The firms that quietly power global financial markets are now turning their attention to something that, until recently, most of Wall Street dismissed as glorified gambling. Wintermute, Jane Street, DRW, and IMC are all actively expanding into prediction markets, providing the liquidity infrastructure that transforms speculative event contracts into something resembling a real asset class.

The numbers behind the shift

Event contract trading has surpassed $60 billion in volume for 2026. Prediction market platforms were processing over $20 billion in monthly volume by early 2026. For context, Wintermute alone handles over $3.5 trillion in annual trading volume across various asset classes. The firm has now committed to providing two-sided liquidity on platforms like Polymarket and Kalshi.

Wintermute isn’t just dipping a toe in. It’s deploying its algorithmic market-making infrastructure, the same technology stack it uses for crypto and traditional markets, to price event contracts with the kind of tight spreads that attract serious capital.

Jane Street, DRW, and IMC are taking a similar approach, each building out dedicated trading desks specifically for prediction markets. Quantitative trading firms across the industry are actively hiring specialists to run these desks.

Galaxy Digital’s institutional play

On June 2, 2026, Galaxy Digital launched an over-the-counter trading desk specifically designed for institutional prediction market activity. The desk kicked off with a $10 million Kalshi trade.

Despite all this activity, institutional participation in prediction markets is estimated to remain under 5% as of 2026. A market already generating $60 billion in annual volume with less than 5% institutional penetration has a lot of room to grow if these firms actually follow through on their infrastructure investments.

What this means for investors

The entry of professional market makers fundamentally changes the character of prediction markets. Better liquidity means tighter spreads, which means lower costs for everyone trading event contracts. It also means more accurate pricing, since firms like Jane Street and Wintermute specialize in finding and eliminating mispricings across markets.

Event contracts can capture risks that traditional financial instruments miss entirely. A futures contract can hedge your exposure to oil prices, but it can’t hedge your exposure to a specific regulatory decision or geopolitical outcome. Prediction markets fill that gap, and the fact that serious institutional players are now treating them as a complement to existing investment strategies rather than a curiosity suggests the asset class has crossed an important credibility threshold.
