Gemini Space Station, the cryptocurrency exchange founded by Tyler and Cameron Winklevoss, surged in its Nasdaq debut Friday after raising $425 million in an initial public offering.

The company priced its IPO late Thursday at $28 a share, valuing Gemini at about $3.3 billion before trading began. That price was above the revised $24 to $26 range it set earlier in the week and well above the initial $17 to $19 range. The offering covered 15.2 million shares.

On Friday, the stock opened at $37.01, a 32% premium to the offer price. Shares climbed as high as $45.89 during intraday trading before settling at $32, still 14% above the IPO level by the close.

Gemini, headquartered in New York, operates a suite of crypto services including a spot exchange, custody solutions for institutions, a U.S. dollar-backed stablecoin, a crypto rewards credit card, and staking products. As of the end of July, the company held more than $21 billion of assets on its platform. Filings show Gemini lost $159 million in 2024 and $283 million in the first half of 2025.

The Winklevoss brothers, who became the first bitcoin billionaires after early investments in the cryptocurrency, appeared on CNBC’s "Squawk Box" on the morning of the IPO. Tyler Winklevoss described bitcoin as “gold 2.0” and said adoption remains in the “first inning.” He and his brother projected that bitcoin could reach $1 million within the next decade.

Gemini’s listing follows those of Coinbase (COIN) in April 2021 and Bullish (BLSH), which owns CoinDesk, last month.
