A crypto exchange platform backed by the billionaire Winklevoss twins has submitted a confidential filing for an initial public offering (IPO) with the U.S. Securities and Exchange Commission (SEC).

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, a cryptocurrency exchange platform backed by the billionaire Winklevoss twins, has filed to go public on the heels of the frenzied debut by stablecoin issuer Circle Internet Group Inc.
