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 the Netherlands. We report what each platform's published rules say about the Netherlands 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 the Netherlands before doing anything. ‘Not listed’ only means a platform's own list doesn't name the Netherlands; 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 the Netherlands: what each platform's own published rules say, and what regulators, courts and police in the Netherlands 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 the Netherlands. 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 the Netherlands; 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 the Netherlands.
Polymarket's Help Center page on geographic restrictions (updated August 14, 2026) names the Netherlands among the 39 countries it lists as blocked, with no country-specific note. Its developer documentation (undated, fetched September 24, 2026) puts the Netherlands in a softer tier: close-only on the website only, with the API not restricted. The two official lists don't match, so we cite both; the dated Help Center page is the one shown in the status card above.
In practice the restriction is Polymarket's own geoblock, put in place under pressure from the Dutch regulator: in its objection, as recorded in the Kansspelautoriteit's decision of June 23, 2026, Polymarket said it had implemented and tested blocking measures for the Netherlands on February 18, 2026, one day after the regulator's deadline of February 17, 2026. The regulator's own check on February 18, 2026 still found the site reachable from a Dutch IP address, which is why one week's penalty was later collected. CasinoNieuws reported on May 6, 2026, citing Het Financieele Dagblad, that Dutch users could no longer bet on Polymarket through its website.
We found no Dutch ISP or DNS block of polymarket.com: the Kansspelautoriteit's published decisions are addressed to the operator, and CasinoBeats reported on May 7, 2026 that the regulator currently has no power to order websites blocked. We found no app-store removal for the Netherlands.
The Netherlands is not on the list of 55 Restricted Jurisdictions in Section VI of Kalshi's Member Agreement (undated; fetched September 24, 2026), and it was not on the first international lists in Kalshi's Exchange Notices of October 23 and November 4, 2025. We found no Kalshi notice, blog post or help article that names the Netherlands. Under the main table's labels that is Not listed, which means only that Kalshi's own list doesn't name the country.
The Dutch regulator's public position covers Kalshi too. On October 23, 2025, before the Dutch general election, the Kansspelautoriteit said, as reported by CasinoNieuws, that prediction markets “such as Polymarket and Kalshi” consider themselves financial exchanges outside gambling law, that it disputes that view and that it was considering further steps. In May 2026 a Ksa spokesperson said, as reported by CasinoNieuws on May 7, 2026, that gambling platforms offering games of chance without a Ksa licence are prohibited, correcting an RTL Tonight item that had called Kalshi legal. As of September 26, 2026, no Ksa decision naming Kalshi is published on the regulator's website.
The regulator is the Kansspelautoriteit (Ksa), the Netherlands Gambling Authority in The Hague. Its decisions against Polymarket are addressed to Adventure One QSS Inc., the company named in Polymarket's terms, under case numbers 22310 and 24971, and rest on Article 1(1)(a) of the Wet op de kansspelen (Betting and Gaming Act), which prohibits offering games of chance without a licence. The Ksa's reasoning is that betting on non-sport events cannot be licensed in the Netherlands at all. We found no statement on either platform from the Autoriteit Financiële Markten (AFM); at EU level, ESMA reminded firms on July 3, 2026 that its binary-option measures apply to event contracts that are financial instruments.
October 23, 2025 (secondary report): in the run-up to the general election of October 29, 2025, the Ksa publicly disputed the platforms' view that they fall outside gambling law and said it was considering further steps, naming both Polymarket and Kalshi (reported by CasinoNieuws). No order was issued at that stage.
January 20, 2026 (official): the Ksa imposed an order subject to a penalty (last onder dwangsom) on Adventure One QSS Inc., requiring it to stop offering Polymarket to the Netherlands by February 17, 2026, on pain of €420,000 per week up to a maximum of €840,000. The order was published on February 17, 2026. Ksa director Ella Seijsener said that companies of this kind offer bets that are not permitted on the Dutch market under any circumstances (our translation), and the Ksa cited Polymarket's markets on the Dutch election. The order concerns the operator, not its users, and is the entry shown as Order to stop in the timeline below.
May 19, 2026 (official): after its check of February 18, 2026 found the site still reachable from a Dutch IP address, the Ksa issued a collection decision (invorderingsbesluit) under Article 5:37 of the Algemene wet bestuursrecht, declaring one week's penalty of €420,000 forfeited and collecting it. It was published on June 19, 2026. Formally this is the collection of a forfeited penalty payment rather than a separate fine; the timeline shows it under the label Fine or penalty. Whether the amount has since been paid is not something we could verify.
June 23, 2026 (official): the Ksa rejected Polymarket's objection (bezwaar) to both the order and its publication and upheld both decisions. Polymarket had argued, among other things, that its markets are not games of chance, that the offer was not aimed at the Netherlands, that it is only an interface to a decentralised protocol, that the penalty was disproportionate and that its block was live on February 18, 2026. The Ksa answered that logging in from a Dutch IP address had been possible with no technical block, that the site showed prices in euros, offered a Dutch-language chatbot and ran markets flagged as Dutch (the next prime minister, Dutch Olympic results), and that Polymarket's own use of the words “bet” and “betting” showed it treated the offer as gambling. The decision was published in July 2026. It states that an appeal (beroep) lies to the administrative-law division of the district court within six weeks; as of September 26, 2026 we found no record of an appeal being filed, and no court decision exists.
June 18–19, 2026 (official): the Ksa was one of nine European gambling regulators (Belgium, France, Germany, Italy, the Netherlands, Poland, Portugal, Spain and Switzerland) that signed a joint statement on prediction markets, pledging coordinated enforcement; the statement itself contains no new order against either platform. No Ksa action has been lifted or reversed, and no Dutch court has ruled on either platform.

Public regulator, court and police actions concerning Polymarket and Kalshi in the Netherlands, as of 2026-09-24. Not legal advice.
This section reports what the law and the authorities in the Netherlands 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 Ksa decision in this case is addressed to the operator, Adventure One QSS Inc. The Ksa's page on tackling illegal online gambling says its enforcement targets illegal providers and those who promote them, and that it works with banks, payment providers and app stores; it says nothing about action against players. We found no prosecution, fine or bank restriction aimed at a Polymarket or Kalshi user in the Netherlands.
The Belastingdienst (tax administration) states a general rule, on a page last modified April 30, 2026, that a person who wins a prize in an online game of chance for which no Dutch licence has been granted, or from a game whose organiser is established abroad, must file a gambling-tax return themselves. That page does not mention prediction markets, and we found no ruling on whether it applies to winnings on Polymarket or Kalshi.
The trigger was the Dutch general election of October 29, 2025. CasinoNieuws reported on October 23, 2025 that Polymarket's market on the next prime minister had passed €1 million in volume and its market on the largest party about €14 million, and that this prompted the Ksa's first public statement.
In May 2026 the RTL Tonight programme said Polymarket was banned in the Netherlands but Kalshi was legal; CasinoNieuws reported on May 7, 2026 that the Ksa corrected this, saying both platforms offer games of chance without a Dutch licence and that comparable sites can be sanctioned. The Ksa has taken no formal step against Kalshi as of September 26, 2026, and Kalshi's own agreement does not restrict the Netherlands, so the two platforms sit differently in the status card above even though the regulator has said both offer games of chance without a Dutch licence.
PolyKal is a read-only research site, and it does not restrict access by country, including from the Netherlands. 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 the Netherlands 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.

the Netherlands 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.
We found no Dutch court order naming Polymarket and no ISP block. What exists is a Kansspelautoriteit order of January 20, 2026 requiring Polymarket's operator to stop offering the site to the Netherlands, a €420,000 penalty collected on May 19, 2026 for missing the deadline, and a decision of June 23, 2026 upholding the order after Polymarket objected. Polymarket's own Help Center now lists the Netherlands as blocked (updated August 14, 2026), and its developer docs describe the country as close-only on the website. Whether that amounts to a “ban” in your situation is not something this page decides.
Kalshi's Member Agreement (fetched September 24, 2026) does not list the Netherlands among its 55 Restricted Jurisdictions; that describes Kalshi's own list only, and ‘not listed’ is not the same as permitted. The Kansspelautoriteit, moreover, has said publicly (October 23, 2025 and May 2026, as reported by CasinoNieuws) that it regards Kalshi's offer, like Polymarket's, as unlicensed gambling; it has issued no decision against Kalshi as of September 26, 2026. This page reports both positions and doesn't say whether trading is legal for you.
The provision the Ksa relies on, Article 1(1)(a) of the Wet op de kansspelen, prohibits offering games of chance without a licence, and every Ksa decision in the Polymarket case is addressed to the operator. The Ksa's enforcement page describes action against providers and promoters, not players, and we found no prosecution or fine of a Dutch user. Separately, the Belastingdienst says winnings from an online game of chance without a Dutch licence must be declared for gambling tax, without mentioning prediction markets. This is a description of the law and the record, not legal advice.
Because the Kansspelautoriteit treats Polymarket's event markets as games of chance that can't be licensed in the Netherlands, and ordered its operator on January 20, 2026 to stop offering them, with a penalty of €420,000 per week. Polymarket says it switched on its Netherlands block on February 18, 2026. In its June 23, 2026 decision the Ksa rejected Polymarket's arguments that its markets are not gambling and were not aimed at the Netherlands, pointing to euro prices, a Dutch-language chatbot and markets on the Dutch prime minister.
Yes. PolyKal's pages are read-only and open from any country, including the Netherlands, without an account: current prices on both platforms, order-book depth, fee comparisons and large-trade data. Viewing data is not trading; PolyKal doesn't place orders, hold funds or give access to either platform, and the Ksa order and Polymarket's own block still apply to trading. See how Polymarket works and how Kalshi works.
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.

This page keeps two things apart for the Netherlands: what each platform's own published rules say, and what regulators, courts and police in the Netherlands have publicly done.

Polymarket's Help Center page on geographic restrictions (updated August 14, 2026) names the Netherlands among the 39 countries it lists as blocked, with no country-specific note.

In practice the restriction is Polymarket's own geoblock, put in place under pressure from the Dutch regulator: in its objection, as recorded in the Kansspelautoriteit's decision of June 23, 2026, Polymarket said it had implemented and tested blocking measures for the Netherlands on February 18, 2026, one day after the regulator's deadline of February 17, 2026.

We found no Dutch ISP or DNS block of polymarket.com: the Kansspelautoriteit's published decisions are addressed to the operator, and CasinoBeats reported on May 7, 2026 that the regulator currently has no power to order websites blocked. We found no app-store removal for the Netherlands.
The Netherlands is not on the list of 55 Restricted Jurisdictions in Section VI of Kalshi's Member Agreement (undated; fetched September 24, 2026), and it was not on the first international lists in Kalshi's Exchange Notices of October 23 and November 4, 2025. We found no Kalshi notice, blog post or help article that names the Netherlands. Under the main table's labels that is Not listed, which means only that Kalshi's own list doesn't name the country.
The Dutch regulator's public position covers Kalshi too. On October 23, 2025, before the Dutch general election, the Kansspelautoriteit said, as reported by CasinoNieuws, that prediction markets “such as Polymarket and Kalshi” consider themselves financial exchanges outside gambling law, that it disputes that view and that it was considering further steps.

As of September 26, 2026, no Ksa decision naming Kalshi is published on the regulator's website.
The regulator is the Kansspelautoriteit (Ksa), the Netherlands Gambling Authority in The Hague. Its decisions against Polymarket are addressed to Adventure One QSS Inc., the company named in Polymarket's terms, under case numbers 22310 and 24971, and rest on Article 1(1)(a) of the Wet op de kansspelen (Betting and Gaming Act), which prohibits offering games of chance without a licence. The Ksa's reasoning is that betting on non-sport events cannot be licensed in the Netherlands at all. We found no statement on either platform from the Autoriteit Financiële Markten (AFM); at EU level, ESMA reminded firms on July 3, 2026 that its binary-option measures apply to event contracts that are financial instruments.
October 23, 2025 (secondary report): in the run-up to the general election of October 29, 2025, the Ksa publicly disputed the platforms' view that they fall outside gambling law and said it was considering further steps, naming both Polymarket and Kalshi (reported by CasinoNieuws). No order was issued at that stage.
January 20, 2026 (official): the Ksa imposed an order subject to a penalty (last onder dwangsom) on Adventure One QSS Inc., requiring it to stop offering Polymarket to the Netherlands by February 17, 2026, on pain of €420,000 per week up to a maximum of €840,000. The order was published on February 17, 2026. Ksa director Ella Seijsener said that companies of this kind offer bets that are not permitted on the Dutch market under any circumstances (our translation), and the Ksa cited Polymarket's markets on the Dutch election. The order concerns the operator, not its users, and is the entry shown as Order to stop in the timeline below.
May 19, 2026 (official): after its check of February 18, 2026 found the site still reachable from a Dutch IP address, the Ksa issued a collection decision (invorderingsbesluit) under Article 5:37 of the Algemene wet bestuursrecht, declaring one week's penalty of €420,000 forfeited and collecting it. It was published on June 19, 2026. Formally this is the collection of a forfeited penalty payment rather than a separate fine; the timeline shows it under the label Fine or penalty. Whether the amount has since been paid is not something we could verify.
June 23, 2026 (official): the Ksa rejected Polymarket's objection (bezwaar) to both the order and its publication and upheld both decisions. Polymarket had argued, among other things, that its markets are not games of chance, that the offer was not aimed at the Netherlands, that it is only an interface to a decentralised protocol, that the penalty was disproportionate and that its block was live on February 18, 2026. The Ksa answered that logging in from a Dutch IP address had been possible with no technical block, that the site showed prices in euros, offered a Dutch-language chatbot and ran markets flagged as Dutch (the next prime minister, Dutch Olympic results), and that Polymarket's own use of the words “bet” and “betting” showed it treated the offer as gambling. The decision was published in July 2026. It states that an appeal (beroep) lies to the administrative-law division of the district court within six weeks; as of September 26, 2026 we found no record of an appeal being filed, and no court decision exists.
June 18–19, 2026 (official): the Ksa was one of nine European gambling regulators (Belgium, France, Germany, Italy, the Netherlands, Poland, Portugal, Spain and Switzerland) that signed a joint statement on prediction markets, pledging coordinated enforcement; the statement itself contains no new order against either platform. No Ksa action has been lifted or reversed, and no Dutch court has ruled on either platform.

What exists is a Kansspelautoriteit order of January 20, 2026 requiring Polymarket's operator to stop offering the site to the Netherlands, a €420,000 penalty collected on May 19, 2026 for missing the deadline, and a decision of June 23, 2026 upholding the order after Polymarket objected. Polymarket's own Help Center now lists the Netherlands as blocked (updated August 14, 2026), and its developer docs describe the country as close-only on the website. Whether that amounts to a “ban” in your situation is not something this page decides.
Kalshi's Member Agreement (fetched September 24, 2026) does not list the Netherlands among its 55 Restricted Jurisdictions; that describes Kalshi's own list only, and ‘not listed’ is not the same as permitted. The Kansspelautoriteit, moreover, has said publicly (October 23, 2025 and May 2026, as reported by CasinoNieuws) that it regards Kalshi's offer, like Polymarket's, as unlicensed gambling; it has issued no decision against Kalshi as of September 26, 2026. This page reports both positions and doesn't say whether trading is legal for you.
The provision the Ksa relies on, Article 1(1)(a) of the Wet op de kansspelen, prohibits offering games of chance without a licence, and every Ksa decision in the Polymarket case is addressed to the operator. The Ksa's enforcement page describes action against providers and promoters, not players, and we found no prosecution or fine of a Dutch user. Separately, the Belastingdienst says winnings from an online game of chance without a Dutch licence must be declared for gambling tax, without mentioning prediction markets. This is a description of the law and the record, not legal advice.
Because the Kansspelautoriteit treats Polymarket's event markets as games of chance that can't be licensed in the Netherlands, and ordered its operator on January 20, 2026 to stop offering them, with a penalty of €420,000 per week. Polymarket says it switched on its Netherlands block on February 18, 2026. In its June 23, 2026 decision the Ksa rejected Polymarket's arguments that its markets are not gambling and were not aimed at the Netherlands, pointing to euro prices, a Dutch-language chatbot and markets on the Dutch prime minister.
Yes. PolyKal's pages are read-only and open from any country, including the Netherlands, without an account: current prices on both platforms, order-book depth, fee comparisons and large-trade data. Viewing data is not trading; PolyKal doesn't place orders, hold funds or give access to either platform, and the Ksa order and Polymarket's own block still apply to trading. See how Polymarket works and how Kalshi works.
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 the Netherlands, 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.
