- The market maker processes over $3.5 trillion in annual trading volume, lending deep liquidity to event contracts.

What Happened
Wintermute, one of crypto’s largest market makers, confirmed it has begun quoting two-sided markets on prediction platforms Polymarket and Kalshi. The London-based firm disclosed the move on Friday, revealing it now provides liquidity for event contracts on both major venues. A person familiar with the matter said this creates a mechanical link between Polymarket and Kalshi, enabling capital to flow dynamically and helping traders execute positions without large price swings. Wintermute’s Head of OTC Trading, Jake Ostrovskis, described the current liquidity profile as “early-stage,” contrasting with rapidly growing demand for prediction markets.
The Numbers
Wintermute claims it processes over $3.5 trillion in annual trading volume, placing it among the most influential market makers in crypto. By quoting two-sided markets across event contracts on two leading platforms, the firm aims to tighten spreads and support larger trade sizes. On the same day, the CFTC issued an order permitting Kalshi to offer Bitcoin perpetual futures to U.S. users—a separate but complementary development that could attract more speculative flow to the platform. The dual announcements signal a deepening of liquidity infrastructure for both prediction markets and crypto derivatives in the United States.
Why It Happened
Prediction markets have seen surging user interest but suffered from wide spreads and shallow order books, limiting their utility for larger traders. Wintermute’s entry directly addresses these structural gaps. As Ostrovskis noted, sustained two-sided liquidity is essential for these markets to become reliable real-time probability estimators. By acting as a neutral market maker—not a bettor—Wintermute profits from the spread while improving price discovery. The CFTC’s concurrent approval of Bitcoin perpetuals on Kalshi suggests a broader regulatory thaw, potentially attracting more institutional participants to the prediction market ecosystem.
Broader Impact
Wintermute’s liquidity provision could accelerate the evolution of prediction markets into legitimate venues for hedging event risk. Tighter spreads and deeper books may draw hedge funds and professional traders seeking exposure to political, economic, or sports outcomes. The CFTC blessing for crypto-settled derivatives on a regulated U.S. platform further blurs the line between prediction markets and traditional finance, possibly opening the door for similar products. This institutional endorsement may boost overall confidence in crypto-based event contracts.
What to Watch Next
- Monitor spreads on Polymarket and Kalshi for signs of tightening as Wintermute deepens its liquidity.
- Watch for other market makers to follow suit, potentially creating a competitive liquidity environment for event contracts.
- The rollout of Bitcoin perpetual futures on Kalshi could influence BTC price discovery and trading volumes, especially if institutional interest grows.
