On Friday, May 29, the British firm Wintermute confirmed that it is now a two-sided liquidity provider in prediction markets. The information, published on the blog of the company —which processes more than $3.5 trillion in annual trading volume— revealed that it actively quotes event contracts on leading venues. Sources close to the matter disclosed that these operations are executed dynamically between Polymarket and Kalshi to facilitate the buying and selling of positions without causing sharp price swings.
This decision is critical for a sector that has surpassed $60 billion in volume so far in 2026. Jake Ostrovskis, Head of OTC Trading at Wintermute, noted that the current liquidity profile of prediction markets is in an “early-stage” that contrasts with its growing demand. By acting as capital providers on both platforms, the firm reduces the gap between buy and sell prices (spread), granting these forecasting spaces the structure and infrastructure of a traditional commodities exchange.
As a next step, this injection of institutional capital will prepare the platforms to handle more complex risk events. Coinciding with this move, the CFTC approved Kalshi on Friday to offer the first regulated Bitcoin perpetual futures contracts in the US, a historic milestone that aligns with Wintermute’s strategy to expand its operations in the US market this year.
