Wintermute, one of the largest crypto market makers, has received approval from the U.S. Securities and Exchange Commission to trade equities, ETF blocks, U.S. stocks and options, and to support ETFs. The move lets the firm apply its algorithmic trading expertise beyond digital assets and into the heart of traditional markets.
A new lane for Wintermute
The approval is broad. Wintermute can now trade individual stocks, handle block trades for ETFs, write options, and provide support for exchange-traded funds. That's a meaningful expansion for a company best known for quoting prices and providing liquidity in crypto markets.
For Wintermute, the approval doesn't just add new instruments. It places the firm in a regulatory framework that governs some of the most active trading venues in the world. The SEC's sign-off is the kind of license that lets a market maker operate across a wider range of products, potentially opening the door to new clients and revenue streams.
Crypto market makers have spent years building sophisticated trading systems designed to handle volatile digital assets. Wintermute's move into equities and options suggests that infrastructure can be repurposed for more traditional fare. The firm's algorithms don't care what the asset is, as long as there's a bid and an ask.
That's not to say it's an easy pivot. Equities and options have their own quirks — different settlement rules, different market structure, different participants. But Wintermute has the capital and the tech to make the jump.
Bridging two markets
The approval is also a sign of the times. Regulators have been cautious about letting crypto-native firms into the traditional financial system, but the lines are blurring. Wintermute is now a bridge between the two worlds — it can trade bitcoin in one portfolio and Apple shares in another.
For the broader industry, the move could encourage other crypto firms to seek similar approvals. If a market maker can operate on both sides, it might help bring liquidity to both markets and reduce some of the friction between them.
Wintermute hasn't said when it will start trading these instruments or how it will phase in its new capabilities. The approval is the first step. The firm will need to build out the operational side — clearing, settlement, compliance — before it can go live in a meaningful way.
But the groundwork is done. Wintermute now has the regulatory green light to become a full-fledged player in U.S. equities and options. That's a rare position for a crypto market maker, and it will be worth watching how the firm uses it.
