Gemini, a crypto exchange run by billionaire twins Tyler and Cameron Winklevoss, on Friday disclosed it had confidentially filed for a U.S. initial public offering, as digital asset firms seize on renewed market momentum.

Cameron and Tyler Winklevoss, who founded Gemini in 2014, were among the most vocal critics of the regulatory clampdown on digital assets companies. Both became active supporters of Trump, contributing to his campaign and to a political action committee funded by the industry to support pro-crypto politicians in Washington.

Gemini, the crypto company controlled by the Winklevoss twins, filed its IPO plans with securities regulators after shares of Circle more than doubled during its first day of trading

Circle, the company behind the $61 billion stablecoin USDC, made a roaring debut on the New York Stock Exchange Thursday, becoming the first stablecoin issuer to go public and making CEO and cofounder Jeremy Allaire a billionaire.

Circle Internet Group Inc.’s initial public offering is likely to price above the marketed range, after fielding orders for more than 25 times the number of shares available in the upsized deal, according to people familiar with the matter.

The cryptocurrency company, which offers fully backed digital money for rapid global payments around the clock, priced its IPO above the expected range.
