Gemini Space Station, Inc. (GEMI)

Gemini is a cryptocurrency platform founded in 2014 by Tyler and Cameron Winklevoss, with a mission to build secure financial infrastructure for the next generation of money and markets. It began as a crypto exchange and has grown into a broader, integrated platform that lets individuals and institutions buy, sell, trade, custody, stake and earn rewards on digital assets, and trade event contracts. Revenue comes mainly from transaction fees on trading volume, plus custody fees, interest income, withdrawal fees, credit card interchange, interest and fees, and, to a so-far immaterial degree, prediction markets and spot margin trading.

Its products include the Gemini Exchange and Gemini ActiveTrader (with perpetual-contract derivatives and, since 2025, spot margin trading of up to 5x leverage), electronic and voice over-the-counter trading desks, and institutional-grade custody through Gemini Trust, a New York limited purpose trust company. It also offers the GUSD stablecoin, regulated by the NYDFS and backed 1:1 by cash and cash equivalents, and staking for ether, solana and monad. The Gemini Credit Card, issued with WebBank and Mastercard, pays crypto rewards. In December 2025 it launched Gemini Predictions, a CFTC-regulated prediction markets platform run by its subsidiary Gemini Titan, a Designated Contract Market. It discontinued its Nifty Gateway NFT marketplace in January 2026. Its venture arm, Gemini Frontier Fund, invests in early-stage crypto projects.

Gemini serves retail users, who use its web and mobile apps, and institutions such as asset managers, hedge funds, proprietary trading firms and corporations. They also use APIs (WebSocket, REST and FIX) for automated trading. As of December 31, 2025, it served users across more than 60 countries, mostly in the United States, with a smaller presence in Asia-Pacific and Europe. In February 2026 it announced plans to exit the United Kingdom, the European Union and other European jurisdictions, and Australia, to focus on the U.S. Growth plans include acquiring retail and institutional users, building out derivatives and prediction markets, and possibly adding U.S. equities, tokenized securities and other derivatives.

Gemini describes itself as a vertically integrated, crypto-native platform with proprietary in-house custody and trading technology, including its own central limit order book and Gemini Instant Liquidity Provider. Its security relies on offline cold storage, geographically distributed hardware security modules and multi-party computation, and it has completed SOC 1 Type 2, SOC 2 Type 2 and ISO 27001 examinations. It operates exchanges through regulated entities in the U.S. and abroad and holds money transmitter licenses in all U.S. states that require them, along with licenses in Europe and Singapore and direct access to fiat banking rails.
