Polymarket, the crypto-based prediction market platform, was banned in the Netherlands in February. But three other platforms — Kalshi, Hyperliquid, and Interactive Brokers — are still offering prediction market services to Dutch users, according to company websites and regulatory filings.
Polymarket's Netherlands exit
The ban came after Dutch regulators determined that Polymarket’s operations violated local gambling laws. The platform blocked access for users with Dutch IP addresses and stopped accepting new registrations from the country. Existing users were given a short window to withdraw funds before the block took effect.
Alternatives that remain open
Kalshi, a U.S.-based regulated prediction market, continues to accept users from the Netherlands. The platform lists contracts on events ranging from Federal Reserve rate decisions to election outcomes. Hyperliquid, a decentralized exchange that offers prediction market-style perpetual contracts, also remains accessible to Dutch traders. Interactive Brokers, the global brokerage, provides a range of event-based derivatives that function similarly to prediction markets.
None of these three companies have announced any restrictions for Dutch users. Their websites still list the Netherlands as a supported jurisdiction, and customer support teams have confirmed availability to prospective users.
Regulatory patchwork
The situation highlights the fragmented nature of prediction market regulation across Europe. Polymarket’s ban stemmed from a specific Dutch law covering online gambling, while the other platforms appear to operate under different legal frameworks — Kalshi as a regulated U.S. exchange, Hyperliquid as a decentralized protocol, and Interactive Brokers as a traditional broker with a derivatives license.
Dutch users now have a choice, but the lack of a unified European stance means the regulatory risk could shift quickly. Any of the remaining platforms could face similar action if Dutch authorities reinterpret the rules.
For now, the three companies are still taking Dutch money and trades. The next move is up to the Dutch gambling authority, which has not commented on whether it plans to investigate the other platforms.
