Tether, the issuer of the largest stablecoin USDT, has set a 14-day deadline for investors to commit to a $500 billion valuation deal. This ambitious funding plan aims to position Tether above major U.S. banks in terms of valuation. The ultimatum requires investors to confirm their commitments within two weeks, or the opportunity will be withdrawn. The proposed valuation would significantly elevate Tether's market standing, surpassing financial giants like JPMorgan and Goldman Sachs. To bolster investor confidence, Tether has engaged a Big Four accounting firm to conduct its first full audit, which could be one of the largest in financial history. Despite rising competition from PayPal and Circle, Tether remains the leader in the stablecoin market with a $184 billion market cap.
