Wintermute, a leading algorithmic trading firm, has announced its entry into prediction markets, providing two-sided liquidity as the sector surpasses $60 billion in trading volume in 2026. The firm is actively quoting markets on platforms like Polymarket and Kalshi, which have seen a combined monthly volume increase from under $5 billion in September 2025 to $24 billion in April 2026. Wintermute joins other major liquidity providers such as Jump Trading and Galaxy Digital, marking a significant institutional interest in event contracts. This move coincides with regulatory developments, including the CFTC's approval for Kalshi to offer Bitcoin perpetual futures in the U.S. Despite regulatory challenges in countries like Spain and the U.S., Wintermute sees potential in the growing liquidity and trading volumes of prediction markets.
