Wintermute Builds a Regulated Route Into US Securities Markets

Digital-asset market maker Wintermute has launched a U.S. broker-dealer, creating a regulated pathway to trade stocks, options and crypto exchange-traded funds in the United States. The move gives the firm a foothold in U.S. securities market structure as it expands its institutional reach.

Expanding Regulated Infrastructure for U.S. Securities

Wintermute’s U.S. entity, Wintermute USA LLC, is registered as a broker-dealer with the Financial Industry Regulatory Authority. A broker-dealer is a regulated entity that buys and sells securities for its own account or on behalf of clients within the U.S. securities oversight framework.

According to the company’s announcement published through PR Newswire, the broker-dealer is intended to support activity in cash equities, listed options and digital-asset ETFs. The combination places Wintermute at the intersection of equities, derivatives and regulated products that provide digital-asset exposure.

Access to stocks and options broadens the markets Wintermute can trade beyond crypto spot and derivatives. Crypto ETFs, meanwhile, package digital-asset exposure in a securities wrapper. The registration therefore formalizes a route for the firm to engage in supervised U.S. securities activity rather than operating only in digital-asset venues.

Reporting by The Block also identified stocks, options and crypto ETFs as the categories tied to the new broker-dealer. The available disclosures establish the registration and the asset classes involved, but do not specify which products Wintermute will trade first or when activity will begin.

Crypto ETF Market Structure

Crypto ETFs are explicitly part of Wintermute’s plans, making the registration relevant to the market infrastructure that supports these regulated products. Broker-dealers can play roles in the trading and support of ETFs, while authorized participants create and redeem ETF shares to help keep fund prices close to the value of their underlying holdings.

Supplementary reporting said BlackRock’s iShares Bitcoin Trust held $43.2 billion at the end of June. The fund’s prospectus names Jane Street, Citadel Securities, Virtu Americas, Goldman Sachs and JPMorgan among its authorized participants. The reported list of authorized participants did not include a crypto company.

Wintermute says it quotes prices across more than 60 venues. Before obtaining broker-dealer registration, the firm could not participate in crypto ETF infrastructure that requires that status. The registration makes Wintermute eligible to apply for market-maker roles and could allow it to seek roles in ETF infrastructure, though no such appointment is confirmed in the available disclosures.

The move is also relevant to institutional counterparties that require regulated intermediaries. A registered broker-dealer may be easier for such institutions to assess and onboard than an unregistered crypto trading firm, although the available evidence does not establish any resulting client mandates, revenue or trading volumes.

Tokenized Securities and Regulatory Positioning

Wintermute’s broker-dealer registration also provides context for the firm’s interest in tokenized securities. In a written submission to the SEC’s Crypto Task Force in September 2025, Wintermute argued that registered broker-dealers should be permitted to trade tokenized equities for their own accounts and maintain custody through self-hosted wallet software.

The filing, available on the SEC website, outlines the firm’s view of how licensed intermediaries could participate in blockchain-based securities markets. It does not establish that regulators have adopted those recommendations or that Wintermute has received authorization for tokenized-equity activity.

More broadly, the registration positions Wintermute within the U.S. securities framework as regulatory treatment of digital-asset products continues to develop. Its stated focus on stocks, options and crypto ETFs reflects an effort to connect crypto-market liquidity with regulated securities products.

What to Watch Next

The next developments will be the practical activation of Wintermute USA’s broker-dealer operations, the products it trades and the counterparties it serves. The current disclosures do not confirm market-maker appointments, authorized-participant agreements or a timetable for those steps.

For crypto ETF markets, the registration creates a potential route for a crypto-native trading firm to seek a more direct role in regulated U.S. securities infrastructure. Whether Wintermute secures those roles will depend on future applications, approvals and commercial arrangements that are not confirmed in the supplied disclosures.
