Wintermute, a leading quantitative market maker in the crypto space, has started providing continuous two-way liquidity on several major prediction market platforms. This move extends their infrastructure into event contracts that blend digital assets and traditional macro themes. The firm now streams bilateral buy and sell quotes across multiple venues, where aggregate monthly prediction market trading volume has exceeded $20 billion in 2026, despite liquidity still being in an early phase by institutional standards.
According to reports, Wintermute already handles over $3.5 trillion in annual trading volume across spot, derivatives, and DeFi markets. This new business line aims to extend their cross-asset capabilities into event contracts covering elections, macro data releases, and crypto-specific flows. Jake Ostrovskis, Wintermute’s head of OTC trading, noted that demand in prediction markets resembles traditional asset classes, but with thinner order books and wider spreads compared to established futures or options.
The firm’s goal is to post continuous bilateral quotes that tighten spreads, deepen liquidity, and make implied probabilities more usable for traders and institutions. Ostrovskis emphasized that tighter spreads and greater trading capacity should improve the quality of probability signals from platforms like Polymarket and Kalshi, turning them into data sources similar to traditional derivatives markets rather than exotic side bets. This aligns with Wintermute Ventures’ broader view that everything becomes tradeable as crypto rails transform prediction markets into financial tools rather than niche gambling.
Wintermute is not alone in this space; firms like Jump Trading and Galaxy Digital already provide liquidity to event contracts. Lifetime trading volume on Polymarket and Kalshi has surpassed $150 billion, based on data from industry trackers. However, monthly turnover has slightly cooled from a record growth run. Ultra-short event contracts tied to bitcoin and ether dominate flows on these platforms, with five-to-15-minute up-down bets on BTC and ETH accounting for over half of their crypto volume.
Regulatory risks are mounting alongside growth. Spain recently ordered ISP-level blocks on both Polymarket and Kalshi over unlicensed gambling concerns, becoming the fifth country to take such action in 2026. Wintermute’s move effectively treats these markets as another derivatives frontier, leveraging stablecoin settlement, on-chain clearing, and automated risk management that resemble the institutional DeFi stacks they are already building through products like the Armitage vault platform. If Armitage represents Wintermute’s bet on DeFi lending running on institutional-style vaults, their push into prediction markets signals a wager that event contracts will evolve into a derivatives-like infrastructure layer rather than remaining a regulatory gray zone.
