SEC Probes Trump Crypto Partner Alt5 Sigma Over Earnings Claims

The U.S. Securities and Exchange Commission has opened an investigation into Jon Isaac, president of the crypto platform Alt5 Sigma, according to multiple reports. Regulators are reviewing allegations that Isaac overstated Alt5 Sigma’s earnings and sold shares during price surges linked to the company’s trading activity. Alt5 Sigma recently partnered with World Liberty Financial, the Trump family’s cryptocurrency venture, to help market and sell $1.5 billion of digital tokens. People familiar with the matter said the inquiry focuses on whether Isaac personally profited from inflated valuations that may have arisen during the project’s promotional phase. The probe adds to a history of regulatory run-ins involving Alt5 Sigma’s father-and-son leadership team. Neither Isaac nor World Liberty Financial has commented publicly on the latest SEC action.
