Wintermute Is Providing Liquidity on Kalshi and Polymarket, Linking Two Giants
Wintermute confirmed it is providing liquidity on prediction markets by quoting two-sided markets on leading event-contract venues, including Polymarket and Kalshi. The firm says this is still an early-stage market but one with growing demand, and that sustained liquidity is needed to narrow spreads, support larger trades, and improve the reliability of market-implied probabilities. The move highlights a key market-making function: liquidity providers do not bet on outcomes, but instead help others trade efficiently and earn the bid-ask spread. Wintermute said its role could help shift prediction markets from a forecasting tool into a broader market for trading event risk. The announcement comes as Kalshi and Polymarket compete in an emerging sector, and as Wintermute signals increased focus on the U.S. market.
