Gemini IPO: bitcoin's first billionaires take the regulated exchange public

Crypto exchange and custody platform — spot trading, staking, institutional custody, a crypto-rewards card and the Gemini dollar stablecoin — with $21B+ assets on platform.

That being the regulated, security-first exchange — not the biggest or cheapest — would win once crypto needed an institutional-grade US on-ramp.

Raised $425M in the IPO (15.2M shares at $28); in May 2026 the founders injected $100M more through Winklevoss Capital — funded in bitcoin.

Olympic rowers Cameron and Tyler Winklevoss bought bitcoin early and became its first billionaires, then founded Gemini in 2014 to be the safe, regulated place to trade it.

Gemini grew into an $18–21B-assets platform (exchange, custody, staking, stablecoin) but kept losing money: $159M in 2024 and $282.5M in H1 2025. When the 2025 crypto-IPO wave opened — Circle had popped 168% in June — Gemini raised its range twice, priced at $28 with Nasdaq taking a $50M strategic stake, and went public on Sept 12, 2025.

Debut +32.2% to a $4.4B valuation — then fundamentals caught up: shares slid from $28 to $5.26 by May 2026 before a quarterly beat (revenue +42% to $50.3M) and the founders' $100M bitcoin-funded investment at $14 a share sparked a 20% premarket jump.

The regulated-exchange bet finally had its market: GENIUS Act clarity and Circle's +168% debut made compliance look like an asset instead of a tax.

Scarcity did the IPO book's work: only the third US-listed crypto exchange (after Coinbase and Bullish), in a 20x-oversubscribed deal.

The Nasdaq brand stake signaled institutional legitimacy beyond the $50M check.

But the underlying business never earned the valuation: deep, repeated losses and fee-compression risk meant the pop had no earnings support.

Founder control cut both ways — it enabled a fast, unconventional bitcoin-funded rescue once public investors headed for the exits.

A hot listing is liquidity, not a verdict: 20x oversubscription and a 32% pop couldn't outrun $440M of losses — eight months on, the founders were rescue-financing their own company in bitcoin.

As of May 2026 Gemini is public, still running its exchange, custody, staking and stablecoin businesses — and still dependent on its founders. GEMI closed at $5.26 on May 14, 2026, about 81% below the $28 IPO price, before jumping 20% premarket on the Q1 beat and the Winklevoss Capital investment: $100M, funded in bitcoin, priced at $14 a share — above the market. Revenue is growing again (+42% YoY to $50.3M) and losses are narrowing, but the stock now trades as a leveraged bet on the twins' conviction that bitcoin goes to $1M.
