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.
