Wintermute says it is quoting two-sided markets on leading prediction venues, and Decrypt reports those include Polymarket and Kalshi.
Intelligence analysis by GPT-5.4 Mini
Wintermute, a major crypto market maker, has moved into prediction markets by supplying liquidity on leading event-contract venues. The report links that activity to both Polymarket and Kalshi, suggesting a new bridge between two large markets.
Wintermute is like a big store owner who is always ready to buy and sell at the same time. That helps other people trade without waiting too long or paying extra.
The story says Wintermute is doing that on prediction sites, including Polymarket and Kalshi. Those sites let people trade on what they think will happen in the future, like a guessing game with money attached.
If the store owner is there all the time, the game works better. Prices move more smoothly, and bigger trades are less likely to cause trouble.
Analysis
What happened
Wintermute confirmed in a Friday blog post that it has been providing liquidity on prediction markets, saying it has been "quoting two-sided markets across event contracts on leading venues." Decrypt reports that the venues include Polymarket and Kalshi.
Why this is notable
Wintermute is one of the biggest names in crypto market making, and the firm says it processes more than $3.5 trillion in annual trading volume. By acting as a liquidity provider rather than a bettor, it says its goal is to tighten spreads and absorb larger trades. That matters because prediction markets rely on active market makers to keep prices tradable and reduce friction for participants.
The link between two giants
The reported presence of Wintermute on both Polymarket and Kalshi creates a mechanical link between two major prediction-market platforms. The story does not say Wintermute is merging the venues or moving assets between them, only that the same liquidity provider is active on both. Even so, that shared market maker can help connect pricing and trading behavior across the two platforms.
What to watch
The article suggests prediction markets are becoming more professionalized, with crypto-native liquidity firms stepping in to support them. If more large market makers follow Wintermute, event contracts could become tighter, deeper, and easier to trade.
