Kalshi's taker fee is 0.07 × contracts × price × (1 − price), times the series multiplier (1 by default) and rounded up to the next cent, so it peaks at 1.75¢ per contract at a 50¢ price. Resting (maker) orders are free on standard series and pay a fee only on the series Kalshi lists with maker fees.
Country-by-country rules, regulator actions and sources for Polymarket and Kalshi.
This is not legal advice, and we don't say whether trading is legal for you in Australia. We report what each platform's published rules say about Australia and the public regulator, court and police actions we could source, each with a date. Those rules change fast, so check the platform's current terms and the law in Australia before doing anything. ‘Not listed’ only means a platform's own list doesn't name Australia; it doesn't mean trading there is permitted.
Status under each platform's own published rules, and the most recent public action we could source, as of 2026-09-24.

This page keeps two things apart for Australia: what each platform's own published rules say, and what regulators, courts and police in Australia have publicly done. A platform's list is its own policy and a government order is the government's, so a country can be on one and not the other.
The status labels are the same as in the main table. Restricted means the platform's own list blocks trading from Australia. Close-only means existing users there can close positions but can't open new ones. Some regions means only named regions are restricted. Separate product means residents use a different, separately regulated product, as US residents do with the Polymarket US app. Not listed means the platform's published list doesn't name Australia; that is not the same as permitted, and a regulator may still block the site.
Polymarket publishes two official lists that don't fully match: its Help Center page (updated August 14, 2026) and its developer docs (undated). We follow the dated Help Center list and say where the developer docs differ. Kalshi statuses follow its Member Agreement as fetched on September 24, 2026; the agreement itself is undated.
Each action shows the authority as it names itself, what it did, the platform it concerns and the date: the date of the action where it was published, otherwise the date it was first reported. Every entry is marked Official, Platform document or Secondary report. Where only secondary reporting exists, we say ‘reported by’ and name the outlet; where official sources conflict, we report both.
‘No public action found’ means our searches found none, not that none exists. Nothing on this page says whether trading is legal for you: for that, check the platforms' current terms and the law in Australia.
Polymarket's Help Center page on geographic restrictions (updated August 14, 2026) lists Australia among the 39 countries where it says trading is blocked, with no Australia-specific note. Its developer docs (undated) put Australia in the group that is close-only on both the website and the API, meaning existing users can close positions but not open new ones. The two lists don't match; we follow the dated Help Center list and record the difference.
In practice there are two layers. Polymarket's own geoblock applies under its list, and since August 13, 2025 ACMA has had polymarket.com on the list of sites it asks Australian internet providers to block, and has also reported it to family-friendly filter providers (ACMA quarterly report, November 2025). We found no Polymarket statement, blog post or press release that names Australia or gives the date it added the country to its list, and ACMA said in August 2025 that it had received no correspondence from the Polymarket service (as quoted by SiGMA, August 22, 2025). Polymarket's Help Center says that using a VPN to get around its restrictions violates its Terms of Use. We found no app-store removal in Australia.
Kalshi's Member Agreement (section VI, undated, fetched September 24, 2026) lists Australia as a Restricted Jurisdiction. Australia was on Kalshi's first published list, in the Exchange Notice of October 23, 2025, on the list in the Notice of November 4, 2025, and is on the current agreement. We found no Kalshi notice or blog post that names Australia.
We found no action by an Australian authority against Kalshi. ACMA told the ABC's 7.30 programme on May 27, 2026 that it ‘continues to monitor prediction market services more broadly’ and ‘has not undertaken formal investigations into other prediction market operators at this time’, and kalshi.com is not on ACMA's blocked-sites list, as Inside Asian Gaming noted on August 4, 2026. Kalshi's restriction of Australia is therefore contractual only. At the same time SBS News reported on June 11, 2026 that almost US$100,000 had been traded on Kalshi's market on the Farrer by-election; the agreement excludes Australia, and we report both.
The regulator that has acted is the Australian Communications and Media Authority (ACMA), which enforces the Interactive Gambling Act 2001 (Commonwealth). ACMA describes the Act as banning online casinos, in-play sports betting, sports betting services that do not hold an Australian licence and betting on lottery outcomes, and it runs the scheme under which internet providers block sites it refers to them. Its finding on Polymarket, as quoted by SiGMA on August 22, 2025, was that ‘the Polymarket service was providing a prohibited interactive gambling service and an unlicensed regulated interactive gambling service that has an Australian link’. The financial regulator, the Australian Securities and Investments Commission (ASIC), oversees financial markets and derivatives under the Corporations Act 2001; its Moneysmart site states that ‘no prediction market operators are licensed as financial markets to operate in Australia’ (page updated August 3, 2026). ASIC's product intervention order banning binary options for retail clients has been in force since May 3, 2021 and was extended to October 1, 2031 (ASIC media release 22-243MR, September 5, 2022); ASIC has not said that it applies to Polymarket or Kalshi contracts, and we found no such statement.
May 16, 2025 (Secondary report quoting ACMA). ACMA confirmed to Crikey that ‘the ACMA has opened an investigation into the provision and advertising of the Polymarket service’. Crikey had reported in April 2025 that Polymarket paid Australian TikTok and Instagram creators to promote its federal-election odds, and its reporters could still open an account and deposit funds from Australia in May 2025. This step concerns the operator.
July 2, 2025 (Official). ACMA issued a Formal Warning to Adventure One QSS, Inc., the operator of Polymarket, for providing a prohibited interactive gambling service and an unlicensed regulated interactive gambling service; the redacted warning was published on ACMA's site in August 2025 and is listed in ACMA's quarterly report for July to September 2025. ACMA said in August 2025 that ‘we have not received any correspondence from the Polymarket service’ (as quoted by SiGMA). The warning targets the operator, not users.
August 13, 2025 (Official). ACMA asked Australian internet providers to block polymarket.com, together with three casino sites (Slot Mafia, Top Aussie Pokies and Spinanga), bringing the total of illegal gambling and affiliate websites blocked since November 2019 to 1,296. ACMA's notice says that people who use illegal services ‘risk losing their money’. Its quarterly report published in November 2025 lists polymarket.com among 71 websites referred to internet providers for blocking and reported to family-friendly filter providers in that quarter, in which ACMA completed 29 investigations and found 44 breaches of the Act. The block is at internet-provider level and targets the site.
2026 statements (Official and Secondary). On May 27, 2026 ACMA told the ABC that it continues to monitor prediction-market services and has opened no formal investigation into other operators, and ASIC told the ABC that ‘no prediction market providers currently hold an Australian market licence’. On August 3, 2026 ASIC published a Moneysmart investment warning on prediction markets; it names neither platform and says users of unlicensed markets ‘will be unable to access important rights and legal protections, including internal dispute resolution processes and client money safeguards’. ASIC Commissioner Alan Kirkland told the ABC on August 4, 2026 that trading on these markets ‘is akin to gambling’, that no operator had applied for a licence, and that Australian-specific markets such as Reserve Bank rate decisions suggested local participation (also reported by Inside Asian Gaming).
We found no court challenge by Polymarket, Kalshi or any user to an Australian action, and no action has been lifted or reversed as of September 26, 2026. ACMA's statement that Polymarket never corresponded with it is the only public indication of the operator's response.

Public regulator, court and police actions concerning Polymarket and Kalshi in Australia, as of 2026-09-24. Not legal advice.
This section reports what the law and the authorities in Australia have said about people who take part in these markets, and any enforcement against users that has been made public. It describes; it doesn't advise.
Every ACMA action to date targets the operator: the formal warning was addressed to Adventure One QSS, Inc. and the block request to internet providers. ACMA's only statement aimed at users is that people who use illegal gambling services ‘risk losing their money’ (August 2025). ACMA also told SBS News on June 11, 2026 that ‘it is not illegal for Australians to circumvent geo-blocking, including through VPNs’; we report that statement as made. Polymarket's own terms prohibit VPN use to get around its restrictions, and PolyKal describes no method. ASIC's Moneysmart warning of August 3, 2026 says that users of unlicensed prediction markets lose access to dispute-resolution processes and client-money safeguards; it describes risks, not sanctions.
We found no prosecution of, or penalty against, a Polymarket or Kalshi user in Australia, no statement from the Australian Taxation Office about prediction-market gains, and no bank or payment restriction specific to either platform.
The Australian case began with advertising. Crikey reported in April and May 2025 that Polymarket had paid Australian TikTok and Instagram creators to promote odds on the May 2025 federal election, and ACMA's investigation covered ‘the provision and advertising’ of the service. Trading on Australian events has continued despite the block: SBS News reported on June 11, 2026 that nearly US$500,000 had been traded on Polymarket and almost US$100,000 on Kalshi on the Farrer by-election, and ASIC's Alan Kirkland pointed on August 4, 2026 to Australian-specific markets such as Reserve Bank rate decisions as a sign of local participation.
There is a public push to license a domestic market. The ABC reported on May 27, 2026 that FEX Global had pitched Australia's first regulated prediction market in Sydney and that former MP Jason Falinski supports legalisation; ASIC said at the time that no provider held an Australian market licence, and on August 4, 2026 that none had applied. We found no sponsorship deal, no statement by the Australian Electoral Commission and no payment-provider restriction specific to Australia.
PolyKal is a read-only research site, and it does not restrict access by country, including from Australia. Its public pages, including prices on both platforms, order-book depth, after-fee cost comparisons, the fee calculator, and large-trade and whale data, need no account. You don't need a VPN to use them.
Viewing public market data is not trading. PolyKal doesn't place orders, hold funds or give access to trading on either platform, and a restriction on Polymarket or Kalshi in Australia still applies to trading there. Polymarket's help center says that using a VPN to get around its restrictions violates its Terms of Use, and Kalshi's Member Agreement excludes people in its restricted jurisdictions; getting around a block can also break local law. PolyKal doesn't help anyone get around them.

Australia is one of 27 countries, plus the United States, that PolyKal tracks. The full availability table shows every country's status under each platform's rules and its regulator actions side by side, with the same dates and sources as this page, and its change log lists every edit we make.
Every entry is re-checked at least once a quarter, and sooner when a platform or regulator announces a change. The next scheduled full re-check is shown in the sidebar.
Two things are true at once. Polymarket's own Help Center (updated August 14, 2026) lists Australia as blocked. Separately, ACMA found that Polymarket was providing a prohibited and an unlicensed regulated interactive gambling service under the Interactive Gambling Act 2001, issued a formal warning to its operator on July 2, 2025, and on August 13, 2025 asked Australian internet providers to block polymarket.com. We found no court challenge and no lifting of that block as of September 26, 2026.
Kalshi's Member Agreement lists Australia as a Restricted Jurisdiction, and has since its first published list of October 23, 2025. We found no action by an Australian authority against Kalshi: ACMA said on May 27, 2026 that it had opened no formal investigation into other prediction-market operators, and kalshi.com is not on ACMA's blocked-sites list. ASIC says no prediction-market operator holds an Australian market licence. Whether trading is lawful for you is not something this page decides.
According to ACMA, because ‘the Polymarket service was providing a prohibited interactive gambling service and an unlicensed regulated interactive gambling service that has an Australian link’ under the Interactive Gambling Act 2001, which, as ACMA describes it, bans online casinos, in-play sports betting and sports betting services without an Australian licence. ACMA opened its investigation in May 2025 into ‘the provision and advertising’ of the service after Crikey reported that Polymarket had paid Australian social-media creators to promote federal-election odds, issued a formal warning on July 2, 2025, received no correspondence from Polymarket, and asked internet providers to block the site on August 13, 2025.
We don't give a verdict for you. What the record shows: the Interactive Gambling Act 2001, as ACMA describes it, targets the providers of prohibited and unlicensed gambling services, and every ACMA action so far has been aimed at Polymarket's operator. ACMA's statement to users is that they ‘risk losing their money’, and it told SBS News in June 2026 that circumventing geo-blocking is not illegal for Australians; ASIC's Moneysmart says users of unlicensed markets lose dispute-resolution and client-money protections. We found no prosecution of a Polymarket or Kalshi user in Australia. Polymarket's own terms prohibit VPN use, and this page describes no way around any block. For your own situation, check the current law and the platform's terms.
Yes, on PolyKal. PolyKal is a read-only research site that shows prices, order-book depth and fee comparisons for both platforms without an account, and it does not restrict access from Australia. Viewing data is not trading: PolyKal places no orders and gives no access to either platform, and ACMA's block of polymarket.com at Australian internet providers is unaffected by anything on this site.
No. Polymarket's help center says that using a VPN to get around its restrictions violates its Terms of Use, and Kalshi's Member Agreement excludes people in its restricted jurisdictions. Getting around a block can also break local law. You don't need a VPN to research these markets: PolyKal's prices, order books and fee calculator don't require one.
We re-check every country page at least once a quarter, and sooner when a platform or regulator announces a change; each rule and action on the page shows its own date and source. If you spot something out of date for Australia, email [email protected] with a link to the new rule or order.

We found no Polymarket statement, blog post or press release that names Australia or gives the date it added the country to its list, and ACMA said in August 2025 that it had received no correspondence from the Polymarket service (as quoted by SiGMA, August 22, 2025). Polymarket's Help Center says that using a VPN to get around its restrictions violates its Terms of Use. We found no app-store removal in Australia.
Kalshi's Member Agreement (section VI, undated, fetched September 24, 2026) lists Australia as a Restricted Jurisdiction. Australia was on Kalshi's first published list, in the Exchange Notice of October 23, 2025, on the list in the Notice of November 4, 2025, and is on the current agreement. We found no Kalshi notice or blog post that names Australia.
We found no action by an Australian authority against Kalshi. ACMA told the ABC's 7.30 programme on May 27, 2026 that it ‘continues to monitor prediction market services more broadly’ and ‘has not undertaken formal investigations into other prediction market operators at this time’, and kalshi.com is not on ACMA's blocked-sites list, as Inside Asian Gaming noted on August 4, 2026. Kalshi's restriction of Australia is therefore contractual only. At the same time SBS News reported on June 11, 2026 that almost US$100,000 had been traded on Kalshi's market on the Farrer by-election; the agreement excludes Australia, and we report both.
The regulator that has acted is the Australian Communications and Media Authority (ACMA), which enforces the Interactive Gambling Act 2001 (Commonwealth). ACMA describes the Act as banning online casinos, in-play sports betting, sports betting services that do not hold an Australian licence and betting on lottery outcomes, and it runs the scheme under which internet providers block sites it refers to them. Its finding on Polymarket, as quoted by SiGMA on August 22, 2025, was that ‘the Polymarket service was providing a prohibited interactive gambling service and an unlicensed regulated interactive gambling service that has an Australian link’. The financial regulator, the Australian Securities and Investments Commission (ASIC), oversees financial markets and derivatives under the Corporations Act 2001; its Moneysmart site states that ‘no prediction market operators are licensed as financial markets to operate in Australia’ (page updated August 3, 2026). ASIC's product intervention order banning binary options for retail clients has been in force since May 3, 2021 and was extended to October 1, 2031 (ASIC media release 22-243MR, September 5, 2022); ASIC has not said that it applies to Polymarket or Kalshi contracts, and we found no such statement.
May 16, 2025 (Secondary report quoting ACMA). ACMA confirmed to Crikey that ‘the ACMA has opened an investigation into the provision and advertising of the Polymarket service’. Crikey had reported in April 2025 that Polymarket paid Australian TikTok and Instagram creators to promote its federal-election odds, and its reporters could still open an account and deposit funds from Australia in May 2025. This step concerns the operator.
July 2, 2025 (Official). ACMA issued a Formal Warning to Adventure One QSS, Inc., the operator of Polymarket, for providing a prohibited interactive gambling service and an unlicensed regulated interactive gambling service; the redacted warning was published on ACMA's site in August 2025 and is listed in ACMA's quarterly report for July to September 2025. ACMA said in August 2025 that ‘we have not received any correspondence from the Polymarket service’ (as quoted by SiGMA). The warning targets the operator, not users.
August 13, 2025 (Official). ACMA asked Australian internet providers to block polymarket.com, together with three casino sites (Slot Mafia, Top Aussie Pokies and Spinanga), bringing the total of illegal gambling and affiliate websites blocked since November 2019 to 1,296. ACMA's notice says that people who use illegal services ‘risk losing their money’. Its quarterly report published in November 2025 lists polymarket.com among 71 websites referred to internet providers for blocking and reported to family-friendly filter providers in that quarter, in which ACMA completed 29 investigations and found 44 breaches of the Act. The block is at internet-provider level and targets the site.
2026 statements (Official and Secondary). On May 27, 2026 ACMA told the ABC that it continues to monitor prediction-market services and has opened no formal investigation into other operators, and ASIC told the ABC that ‘no prediction market providers currently hold an Australian market licence’. On August 3, 2026 ASIC published a Moneysmart investment warning on prediction markets; it names neither platform and says users of unlicensed markets ‘will be unable to access important rights and legal protections, including internal dispute resolution processes and client money safeguards’. ASIC Commissioner Alan Kirkland told the ABC on August 4, 2026 that trading on these markets ‘is akin to gambling’, that no operator had applied for a licence, and that Australian-specific markets such as Reserve Bank rate decisions suggested local participation (also reported by Inside Asian Gaming).
We found no court challenge by Polymarket, Kalshi or any user to an Australian action, and no action has been lifted or reversed as of September 26, 2026. ACMA's statement that Polymarket never corresponded with it is the only public indication of the operator's response.

This section reports what the law and the authorities in Australia have said about people who take part in these markets, and any enforcement against users that has been made public. It describes; it doesn't advise.
Every ACMA action to date targets the operator: the formal warning was addressed to Adventure One QSS, Inc. and the block request to internet providers. ACMA's only statement aimed at users is that people who use illegal gambling services ‘risk losing their money’ (August 2025). ACMA also told SBS News on June 11, 2026 that ‘it is not illegal for Australians to circumvent geo-blocking, including through VPNs’; we report that statement as made.

The Australian case began with advertising. Crikey reported in April and May 2025 that Polymarket had paid Australian TikTok and Instagram creators to promote odds on the May 2025 federal election, and ACMA's investigation covered ‘the provision and advertising’ of the service. Trading on Australian events has continued despite the block: SBS News reported on June 11, 2026 that nearly US$500,000 had been traded on Polymarket and almost US$100,000 on Kalshi on the Farrer by-election, and ASIC's Alan Kirkland pointed on August 4, 2026 to Australian-specific markets such as Reserve Bank rate decisions as a sign of local participation.

Two things are true at once. Polymarket's own Help Center (updated August 14, 2026) lists Australia as blocked. Separately, ACMA found that Polymarket was providing a prohibited and an unlicensed regulated interactive gambling service under the Interactive Gambling Act 2001, issued a formal warning to its operator on July 2, 2025, and on August 13, 2025 asked Australian internet providers to block polymarket.com. We found no court challenge and no lifting of that block as of September 26, 2026.
Kalshi's Member Agreement lists Australia as a Restricted Jurisdiction, and has since its first published list of October 23, 2025. We found no action by an Australian authority against Kalshi: ACMA said on May 27, 2026 that it had opened no formal investigation into other prediction-market operators, and kalshi.com is not on ACMA's blocked-sites list. ASIC says no prediction-market operator holds an Australian market licence. Whether trading is lawful for you is not something this page decides.
According to ACMA, because ‘the Polymarket service was providing a prohibited interactive gambling service and an unlicensed regulated interactive gambling service that has an Australian link’ under the Interactive Gambling Act 2001, which, as ACMA describes it, bans online casinos, in-play sports betting and sports betting services without an Australian licence. ACMA opened its investigation in May 2025 into ‘the provision and advertising’ of the service after Crikey reported that Polymarket had paid Australian social-media creators to promote federal-election odds, issued a formal warning on July 2, 2025, received no correspondence from Polymarket, and asked internet providers to block the site on August 13, 2025.
We don't give a verdict for you. What the record shows: the Interactive Gambling Act 2001, as ACMA describes it, targets the providers of prohibited and unlicensed gambling services, and every ACMA action so far has been aimed at Polymarket's operator. ACMA's statement to users is that they ‘risk losing their money’, and it told SBS News in June 2026 that circumventing geo-blocking is not illegal for Australians; ASIC's Moneysmart says users of unlicensed markets lose dispute-resolution and client-money protections. We found no prosecution of a Polymarket or Kalshi user in Australia. Polymarket's own terms prohibit VPN use, and this page describes no way around any block. For your own situation, check the current law and the platform's terms.
Yes, on PolyKal. PolyKal is a read-only research site that shows prices, order-book depth and fee comparisons for both platforms without an account, and it does not restrict access from Australia. Viewing data is not trading: PolyKal places no orders and gives no access to either platform, and ACMA's block of polymarket.com at Australian internet providers is unaffected by anything on this site.
No. Polymarket's help center says that using a VPN to get around its restrictions violates its Terms of Use, and Kalshi's Member Agreement excludes people in its restricted jurisdictions. Getting around a block can also break local law. You don't need a VPN to research these markets: PolyKal's prices, order books and fee calculator don't require one.
We re-check every country page at least once a quarter, and sooner when a platform or regulator announces a change; each rule and action on the page shows its own date and source. If you spot something out of date for Australia, email [email protected] with a link to the new rule or order.
Every statement on this page rests on the sources below. Platform rules were checked against Polymarket's and Kalshi's own pages on September 24, 2026; regulator, court and police actions were checked against the sources listed on September 24–26, 2026. Each source is marked as official, a platform document or a secondary report. Where only secondary reporting was available, we cite it and say so; where official sources conflict, we report both. We re-verify this page quarterly.
