SEC Probes Trading Affiliates of Crypto Giant Binance’s U.S. Arm

The Securities and Exchange Commission is examining the relationship between the U.S. arm of Binance, the world’s largest cryptocurrency exchange, and two trading firms with ties to Binance’s founder, people familiar with the probe say.

The two trading firms, Sigma Chain AG and Merit Peak Ltd., act as market makers that trade cryptocurrencies on the Binance.US exchange. One area of focus for regulators is how Binance.US disclosed to customers its links to the trading firms, the people say.
