The SEC’s investigation, which has been continuing for months, is focused on the company’s U.S. subsidiary, FTX. US, which lists dozens of crypto tokens. Agency officials believe some of these assets, as well as FTX’s lending product, might constitute securities that, under U.S. law, should have been registered with the SEC before being sold to investors, the person said. If that is the case, then the company’s handling of customer assets might also violate laws governing U.S. exchanges.
