Tether's secondary market trading valuation is estimated to be between $350 billion and $375 billion, which is notably higher than previous assessments. According to NS3.AI, this substantial valuation suggests that CFO Giancarlo Devasini's stake could be valued at over $156 billion, potentially surpassing the net worth of renowned investor Warren Buffett.

The company is also expanding its operations with initiatives such as the USAT stablecoin, which is issued through Anchorage Digital Bank.
