(Reuters) -Crypto firm Gemini said on Friday it had confidentially filed for a U.S. initial public offering, as digital asset companies move to tap into renewed investor risk appetite amid improving market conditions.

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.
