Switzerland Blocked Four More Domains Carrying Polymarket's Name

Switzerland's Gambling Supervisory Authority, Gespa, publishes the list of gambling sites that Swiss internet providers must block, each with the date it was added. The list dated 25 August 2026 has 887 entries.

polymarket.com has been on it since 26 November 2024 and kalshi.com since 25 November 2025. On 25 August 2026 Gespa added four Swiss domains carrying Polymarket's name: polymarket-swiss.ch, polymarketschweiz.ch, polymarketsuisse.ch and polymarketswitzerland.ch. The list does not say who registered them.

The four Polymarket domains were among 52 entries added on 25 August 2026 alone. With 216 entries by that date, 2026 had already passed every full year since the list began.

Gespa considers prediction markets to be gambling under Swiss law. In a media release of 17 June 2026, issued as it joined a statement of eight other European regulators, it said that providers from abroad who offer gambling in Switzerland without authorisation do so illegally, and that access to their websites will be blocked.

"The protection afforded by the Swiss Gambling Act does not apply to bets placed on these platforms," said Gespa's director, Manuel Richard. The release put bets on the football World Cup winner on Polymarket alone at about 2.5 billion dollars.

Switzerland is not on Polymarket's restrictions page, read on 21 October 2026. The Swiss block rests on internet providers alone, and network tests in the Europe tracker found it holding on some networks and not on others.
