Polymarket bets on Europe as Kalshi gains US market share
Polymarket is making a major strategic push into Europe, according to a Bloomberg opinion piece published October 1. The article frames the expansion as a significant geographic diversification for the US political and event trading brand. A video opinion piece published October 4 presents the European push against the backdrop of Kalshi overtaking Polymarket in market share, showing a chart of the competitive shift.
Polymarket's European push is a direct response to Kalshi seizing US market share on event contracts. The competitive reversal means Polymarket must build a new user base abroad or cede the leadership position it held through the 2024 election cycle. Europe offers scale but no shortcut: the platform faces lobbying for regulatory licensing market by market, without the operational template it refined stateside.
Kalshi, meanwhile, deepens its American foothold through partnerships like its FanDuel liquidity deal. The risk for Polymarket is dual failure — losing the US volume race while European traction remains years away. Its brand recognition from political trading does not transfer automatically to eurozone sports and macro contracts, where local platforms already hold trust. The timeline is compressed by venture expectations after competitor valuations set a steep benchmark for growth proof-points.
Polymarket's European push joins a broadening debate over prediction markets' social legitimacy, following the Mormon church's moral condemnation and ongoing state-level fights in New York, Ohio, and Tennessee.
