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 Taiwan. We report what each platform's published rules say about Taiwan 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 Taiwan before doing anything. ‘Not listed’ only means a platform's own list doesn't name Taiwan; 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 Taiwan: what each platform's own published rules say, and what regulators, courts and police in Taiwan 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 Taiwan. 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 Taiwan; 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 Taiwan.
Polymarket's Help Center page on geographic restrictions, updated August 14, 2026, names Taiwan twice: among the 39 countries it lists as blocked, and in its close-only group with Singapore, Poland and Thailand, where ‘users may close their existing positions but cannot open new ones’. Its undated developer geoblock documentation puts Taiwan in the tier that is close-only on both the website and the API. Because the close-only wording is the more specific rule and both documents agree on it, Taiwan is Close-only for Polymarket under this site's labels. We found no Polymarket publication giving the date on which it applied that rule to Taiwan.
In practice two restrictions overlap. Polymarket's own geoblock stops new positions from Taiwan, and separately the polymarket.com domain is blocked inside Taiwan: first by the Criminal Investigation Bureau through Taiwan's domain registrar in December 2023, and since May 2026 under a court ruling, with Taiwanese ISPs showing a blocking notice (details below). Polymarket still runs a Traditional Chinese interface and a Taiwan topic page, including the market ‘2026 Taiwanese Local Elections: Party Winner’ and markets on whether China will invade Taiwan; those markets remain open to traders outside Taiwan. We found no app-store removal order and no Polymarket statement naming Taiwan.
Taiwan is on the list of 55 Restricted Jurisdictions in Section VI of Kalshi's Member Agreement (undated; fetched September 24, 2026), and it has been there since Kalshi's first international list in its Exchange Notice of October 23, 2025, repeated in the notice of November 4, 2025. Under this site's labels Taiwan is Restricted for Kalshi: Kalshi's own agreement excludes people in Taiwan. Kalshi gives no country-specific reason, and its help center (updated March 20, 2026) says trading from outside the United States is subject to that agreement. We found no Kalshi blog post or notice naming Taiwan, and no Taiwanese regulator, court or police action naming Kalshi.
Taiwan has no regulator dedicated to prediction markets, and we found no statement about either platform from the Financial Supervisory Commission or the Central Election Commission. The actions come from the police and prosecutors: the Criminal Investigation Bureau (刑事警察局, CIB) of the National Police Agency, county and city police departments, and district prosecutors' offices under the Ministry of Justice, with the 2026 domain block reportedly ordered by the Miaoli District Court. The law they cite is Article 88-1 of the Presidential and Vice Presidential Election and Recall Act (總統副總統選舉罷免法, added in 2023): betting on the election result in public or ‘by telecommunications, electronic communications, the internet or similar means’ carries up to 6 months' imprisonment, detention or a fine of up to NT$100,000, and running or hosting such betting for profit carries up to 5 years' imprisonment and a fine of up to NT$500,000 (Yunlin County Police via the National Police Agency's radio service, December 19, 2023; Changhua District Prosecutors Office press release, January 10, 2024; both official). The Public Officials Election and Recall Act (公職人員選舉罷免法) contains a parallel provision with the same penalties for local elections, and the Qiaotou District Prosecutors Office's indictment of May 8, 2026 also cites Article 266 of the Criminal Code (gambling, including over the internet).
The first election cycle, 2023–2024. December 19, 2023: Yunlin County Police announced the arrest of 17 people who had bet on Polymarket's ‘Taiwan Presidential Election’ market, which showed US$311,534 in volume; about NT$171,661 in crypto-assets was seized after the CIB traced the flows (official). December 22, 2023: the CIB, working with Taiwan's domain registrar, blocked polymarket.com inside Taiwan and said the block was domestic only; Taiwan News reported it on January 2, 2024, and we found no CIB press release, which is why the timeline below marks this entry as a secondary report; it is shown there as Blocking order. By January 2, 2024, Miaoli police had arrested 11 more people, with about NT$247,000 in crypto-assets seized (Taiwan News). January 10, 2024: the Changhua District Prosecutors Office announced the seizure of 389.87 USDC from two bettors, citing Article 88-1, paragraphs 1 and 2 (official). CoinDesk described Taiwan on January 13, 2025 as the first jurisdiction to block Polymarket and prosecute its own nationals.
The second cycle, 2026. May 8, 2026: the Qiaotou District Prosecutors Office in Kaohsiung indicted the first person charged over the November 2026 local elections, who had placed 742.96 USDC (about NT$23,457) on the market ‘2026 Taiwanese Local Elections: Party Winner’; a search warrant was executed and 746.79 USDC seized, and the prosecutor said such markets ‘distort voters' perception of the race’ (official). ABMedia reported on May 9, 2026 that the defendant had used a VPN with a Japanese IP address and was identified anyway. By May 12, 2026, polymarket.com was blocked again in Taiwan, this time under Miaoli District Court criminal ruling 115年聲扣字第4號 for suspected violation of the Public Officials Election and Recall Act, with ISPs showing a blocking notice (reported by BlockTempo, May 12, 2026, and Blockcast, May 22, 2026; we did not obtain the ruling itself, and the exact date the block took effect is not published). May 18–19, 2026: police in Yunlin, Miaoli, Taichung and Kaohsiung summoned further Polymarket users, including a developer whose trading bot had placed 3 USDT on a Taiwan market (BlockTempo, May 18, 2026; Blockcast, May 22, 2026). June 8, 2026: the Taoyuan District Prosecutors Office gave deferred prosecution to four people who had confessed to 2026 local-election bets and disgorged their gains, after investigations spanning several counties including Kinmen (reported by UDN).
Every action so far has been aimed at users, not at Polymarket as a company: the domain is blocked, but we found no proceeding, fine or order against Polymarket itself, no court challenge by either platform, and no report of a block being lifted. The 2023 block was a domain block arranged with the registrar; the 2026 block is a court-ordered domain block implemented by ISPs. The user cases have ended in convictions or deferred prosecutions, and we found no appeal that tests whether prediction-market trading as such is gambling under Taiwanese law. We found no Taiwanese action against Kalshi.

Public regulator, court and police actions concerning Polymarket and Kalshi in Taiwan, as of 2026-09-24. Not legal advice.
This section reports what the law and the authorities in Taiwan 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.
The law states the participant penalty directly: under Article 88-1 of the Presidential and Vice Presidential Election and Recall Act and the parallel provision of the Public Officials Election and Recall Act, a person who bets on an election result faces up to 6 months' imprisonment, detention or a fine of up to NT$100,000; the ‘up to 5 years’ figure that appears in some English reports is the penalty for running such betting for profit. The sentences actually imposed are lighter. ABMedia's review of about 10 judgments from the Hsinchu, Miaoli, Taoyuan, Taichung and Yunlin district courts, published April 3, 2026, found detention of 20 to 55 days, usually with a suspended sentence of one to two years, and forfeiture of between 49.99 and 1,005.94 USDC; it found no acquittals. More than 30 people have been investigated across the two election cycles (Taiwan News, January 2, 2024; BlockTempo, May 18, 2026), with roughly US$700,000 wagered on the 2024 presidential market.
According to ABMedia (April 3, 2026) and Blockcast (May 22, 2026), prosecutors identified bettors by matching on-chain wallets to identity records held by exchanges licensed in Taiwan, and using a VPN did not prevent identification. The Qiaotou indictment shows the same route: the defendant's USDC had been bought on a Taiwan-based exchange before being moved to a self-custody wallet. We found no policy from any Taiwanese exchange or bank that names Polymarket or Kalshi, no Ministry of Finance statement on the tax treatment of prediction-market gains, and no case in which a Kalshi user was investigated.
On May 18, 2026, UDN reported that the Legislative Yuan's Legal Affairs Bureau had issued a report recommending amendments to both Election and Recall Acts and to the Criminal Code so that the ‘attempt’ stage (placing an order that is never filled) can be punished, virtual spaces count as gambling venues, and confiscation of virtual assets becomes mandatory; the DPP, TPP and KMT caucuses commented, and a KMT legislator noted that the Virtual Asset Service Act (虛擬資產服務法) was still in committee. We found no report of any such bill passing as of September 26, 2026.
PolyKal is a read-only research site, and it does not restrict access by country, including from Taiwan. 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 Taiwan 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.
Start with the compare page, the fee calculator or large trades, or read how Polymarket works and how Kalshi works.
Taiwan 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.
The domain is blocked inside Taiwan, and Polymarket's own rules restrict Taiwan too. The Criminal Investigation Bureau had polymarket.com blocked through Taiwan's domain registrar on December 22, 2023 (reported by Taiwan News), and by May 12, 2026 it was blocked again under a Miaoli District Court ruling, with ISPs showing a notice (reported by BlockTempo and Blockcast). Separately, Polymarket's Help Center (updated August 14, 2026) lists Taiwan as close-only: existing positions can be closed, new ones can't be opened. No proceeding against Polymarket as a company has been made public; the enforcement has been against users.
We don't decide that for you, but Taiwan is the one country PolyKal tracks where courts have already convicted users. What the record shows: betting on an election result is an offence under Article 88-1 of the Presidential and Vice Presidential Election and Recall Act and the parallel provision for local elections, punishable by up to 6 months' imprisonment, detention or a fine of up to NT$100,000; prosecutors have also cited Article 266 of the Criminal Code. About 10 judgments reviewed by ABMedia (April 3, 2026) imposed 20 to 55 days' detention, mostly suspended, plus forfeiture of the USDC used. Those cases concern election markets; we found no Taiwanese ruling on prediction markets about other subjects. Check the current law before doing anything.
Kalshi's own Member Agreement (Section VI, fetched September 24, 2026) lists Taiwan as a restricted jurisdiction and has done so since its first international list of October 23, 2025, so Kalshi's contract excludes people in Taiwan. We found no Taiwanese authority that has acted against Kalshi by name, but the election-betting provisions described on this page apply regardless of platform.
Police arrested 17 people in Yunlin on December 19, 2023 and 11 more in Miaoli by January 2, 2024 over the 2024 presidential election market; prosecutors in Changhua seized 389.87 USDC from two bettors on January 10, 2024. About 10 court judgments reviewed by ABMedia (April 3, 2026) imposed 20 to 55 days' detention, usually suspended, and forfeited the USDC. For the November 2026 local elections, the Qiaotou District Prosecutors Office indicted a first bettor on May 8, 2026, police summoned more users on May 18–19, 2026, and the Taoyuan District Prosecutors Office gave four people deferred prosecution on June 8, 2026 (reported by UDN). More than 30 people have been investigated in all.
Yes, on PolyKal. Its pages load from Taiwan without an account and show prices, order-book depth and after-fee comparisons for both platforms, including for the Taiwan markets Polymarket runs. Viewing data is not trading: PolyKal doesn't place orders or hold funds, and the domain block, Polymarket's close-only rule, Kalshi's restriction and the election-betting law described on this page all still apply to trading.
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 Taiwan, 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.

Public regulator, court and police actions concerning Polymarket and Kalshi in Taiwan, as of 2026-09-24. Not legal advice.
This section reports what the law and the authorities in Taiwan 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.
The law states the participant penalty directly: under Article 88-1 of the Presidential and Vice Presidential Election and Recall Act and the parallel provision of the Public Officials Election and Recall Act, a person who bets on an election result faces up to 6 months' imprisonment, detention or a fine of up to NT$100,000; the ‘up to 5 years’ figure that appears in some English reports is the penalty for running such betting for profit. The sentences actually imposed are lighter. ABMedia's review of about 10 judgments from the Hsinchu, Miaoli, Taoyuan, Taichung and Yunlin district courts, published April 3, 2026, found detention of 20 to 55 days, usually with a suspended sentence of one to two years, and forfeiture of between 49.99 and 1,005.94 USDC; it found no acquittals. More than 30 people have been investigated across the two election cycles (Taiwan News, January 2, 2024; BlockTempo, May 18, 2026), with roughly US$700,000 wagered on the 2024 presidential market.
According to ABMedia (April 3, 2026) and Blockcast (May 22, 2026), prosecutors identified bettors by matching on-chain wallets to identity records held by exchanges licensed in Taiwan, and using a VPN did not prevent identification. The Qiaotou indictment shows the same route: the defendant's USDC had been bought on a Taiwan-based exchange before being moved to a self-custody wallet. We found no policy from any Taiwanese exchange or bank that names Polymarket or Kalshi, no Ministry of Finance statement on the tax treatment of prediction-market gains, and no case in which a Kalshi user was investigated.
On May 18, 2026, UDN reported that the Legislative Yuan's Legal Affairs Bureau had issued a report recommending amendments to both Election and Recall Acts and to the Criminal Code so that the ‘attempt’ stage (placing an order that is never filled) can be punished, virtual spaces count as gambling venues, and confiscation of virtual assets becomes mandatory; the DPP, TPP and KMT caucuses commented, and a KMT legislator noted that the Virtual Asset Service Act (虛擬資產服務法) was still in committee. We found no report of any such bill passing as of September 26, 2026.
PolyKal is a read-only research site, and it does not restrict access by country, including from Taiwan. 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 Taiwan 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.
Start with the compare page, the fee calculator or large trades, or read how Polymarket works and how Kalshi works.
Taiwan 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.
The domain is blocked inside Taiwan, and Polymarket's own rules restrict Taiwan too. The Criminal Investigation Bureau had polymarket.com blocked through Taiwan's domain registrar on December 22, 2023 (reported by Taiwan News), and by May 12, 2026 it was blocked again under a Miaoli District Court ruling, with ISPs showing a notice (reported by BlockTempo and Blockcast). Separately, Polymarket's Help Center (updated August 14, 2026) lists Taiwan as close-only: existing positions can be closed, new ones can't be opened. No proceeding against Polymarket as a company has been made public; the enforcement has been against users.
We don't decide that for you, but Taiwan is the one country PolyKal tracks where courts have already convicted users. What the record shows: betting on an election result is an offence under Article 88-1 of the Presidential and Vice Presidential Election and Recall Act and the parallel provision for local elections, punishable by up to 6 months' imprisonment, detention or a fine of up to NT$100,000; prosecutors have also cited Article 266 of the Criminal Code. About 10 judgments reviewed by ABMedia (April 3, 2026) imposed 20 to 55 days' detention, mostly suspended, plus forfeiture of the USDC used. Those cases concern election markets; we found no Taiwanese ruling on prediction markets about other subjects. Check the current law before doing anything.
Kalshi's own Member Agreement (Section VI, fetched September 24, 2026) lists Taiwan as a restricted jurisdiction and has done so since its first international list of October 23, 2025, so Kalshi's contract excludes people in Taiwan. We found no Taiwanese authority that has acted against Kalshi by name, but the election-betting provisions described on this page apply regardless of platform.
Police arrested 17 people in Yunlin on December 19, 2023 and 11 more in Miaoli by January 2, 2024 over the 2024 presidential election market; prosecutors in Changhua seized 389.87 USDC from two bettors on January 10, 2024. About 10 court judgments reviewed by ABMedia (April 3, 2026) imposed 20 to 55 days' detention, usually suspended, and forfeited the USDC. For the November 2026 local elections, the Qiaotou District Prosecutors Office indicted a first bettor on May 8, 2026, police summoned more users on May 18–19, 2026, and the Taoyuan District Prosecutors Office gave four people deferred prosecution on June 8, 2026 (reported by UDN). More than 30 people have been investigated in all.
Yes, on PolyKal. Its pages load from Taiwan without an account and show prices, order-book depth and after-fee comparisons for both platforms, including for the Taiwan markets Polymarket runs. Viewing data is not trading: PolyKal doesn't place orders or hold funds, and the domain block, Polymarket's close-only rule, Kalshi's restriction and the election-betting law described on this page all still apply to trading.
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 Taiwan, 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.
