Wintermute pushes into prediction markets with $20b monthly volumes

Wintermute is entering the world of prediction markets, joining other major financial institutions in a competition to lead the rapidly growing market for event-based contracts, which currently handle over $20 billion in trades each month.

Summary

  • Wintermute begins two way market making on major prediction platforms
  • Monthly prediction market volume above $20 billion as lifetime flows top $150 billion
  • Move follows institutional push into Polymarket and Kalshi style event contracts

Wintermute, a major player in crypto trading, is now offering constant buying and selling options on several popular prediction market platforms. This expands their services to include contracts based on both cryptocurrencies and traditional economic events, as reported by The Block.

The company shared with The Block that it’s currently providing real-time buy and sell prices across several platforms. These platforms are seeing significant growth in prediction market trading, exceeding $20 billion monthly by 2026, although trading volume is still developing to meet the needs of larger institutional investors.

As an analyst, I’m seeing that Wintermute currently handles over $3.5 trillion in trades every year across various markets – everything from traditional spot and derivative markets to the decentralized finance (DeFi) space. They’re now expanding into ‘event contracts,’ which are essentially bets on the outcomes of things like elections, major economic data releases, and even movements within the crypto market itself. This new line of business aims to leverage their existing trading infrastructure to cover these event-based opportunities.

Wintermute’s thesis on event contracts

Jake Ostrovskis, who leads trading at Wintermute, believes that demand for prediction markets is starting to look a lot like traditional investments. While the way people buy and sell is similar to stocks or futures, these markets currently have less trading volume and bigger differences between buying and selling prices.

He explained to The Block that while there’s definitely interest in these markets, they currently lack enough trading activity. Wintermute aims to address this by consistently offering direct quotes, which should reduce price differences, increase trading volume, and provide clearer, more helpful information for traders and larger financial institutions.

Ostrovskis believes that if platforms like Polymarket and Kalshi can narrow the difference between buying and selling prices and handle more trades, the information they provide will become more reliable. This would make them similar to traditional financial markets, rather than simply unusual or risky bets.

This idea aligns with Wintermute Ventures’ belief that anything can eventually be bought and sold as cryptocurrency technology transforms prediction markets from simple betting into sophisticated financial tools. The firm first highlighted this trend in a 2026 forecast reported by Yahoo Finance.

Polymarket, Kalshi and institutional liquidity

Wintermute is not the first big trading shop to see an opening in event markets.

According to The Block, companies like Jump Trading and Galaxy Digital are already actively involved in providing funds for trading on prediction markets. These markets, specifically Polymarket and Kalshi, have now seen over $150 billion in trading volume, according to data from CoinMarketCap and The Block’s own tracking tools.

A large Ethereum trader, known as an OTC whale (0xFB7), recently purchased $40.48 million worth of ETH (20,000 units) from FalconX. They also transferred $50 million in USDT to Wintermute, probably to buy even more ETH there. This whale currently holds a total of 143,906 ETH, worth approximately $317.6 million.

The total value of all trades ever made on both platforms reaches $150 billion. However, recent monthly trading volume has decreased a bit after a period of significant growth, the report indicates.

Polymarket and Kalshi are seeing a surge in very short-term bets on Bitcoin and Ether. These bets, which predict whether the price of BTC or ETH will go up or down in just five to fifteen minutes, now make up over half of all crypto trading volume on those platforms, as reported previously.

As these prediction markets grow in popularity, so do the legal challenges. This month, Spain joined four other countries in 2026 by ordering internet service providers to block access to Polymarket and Kalshi, citing concerns about illegal gambling, according to a recent report on the crypto industry.

Wintermute is approaching these markets much like the cutting edge of derivatives trading. They’re utilizing stablecoins for settlements, on-chain clearing processes, and automated risk management – all features that closely resemble the advanced DeFi systems the company is already developing, as seen in their new Armitage vault platform (as previously reported by Bitcoin).

If Armitage represents Wintermute’s belief in a more structured approach to DeFi lending—using institutional-grade vaults—then its move into prediction markets signals a bet that these markets will evolve into a robust foundation for financial derivatives, rather than stay stuck as unregulated and risky gambling platforms.
