Wintermute Enters Prediction Markets as Liquidity Provider
According to Wintermute, the firm has begun quoting two-sided prices in prediction markets, adding professional market-making capacity to a fast-growing venue for trading event-driven risk.
Fact Check
Wintermute's own announcement page (wintermute.com) confirms it is providing two-sided liquidity on event contracts and that venues collectively exceed $20B in monthly volume in early 2026. The Block article (Brian Danga, May 29, 2026), citing Wintermute's statement, additionally confirms Polymarket and Kalshi together crossed $150 billion in cumulative lifetime volume as of April 2026. BlockBeats independently reports the same two numbers. All elements of the claim are corroborated by primary and reputable secondary sources.
Summary
Wintermute said it has entered prediction markets as a liquidity provider, quoting both buy and sell prices across the sector. The firm’s move adds professional market-making capacity to a market that has grown into a major venue for trading real-world event risk. The new information does not materially change the existing account that Wintermute is providing two-sided liquidity across major prediction market platforms and supporting trading efficiency as the sector scales.
