Tether is reportedly raising funds at a $500 billion valuation, aiming for $20 billion in funding, which would make it the most valuable private company globally alongside OpenAI. This valuation would position Tether as the second-largest bank by market cap, surpassing Bank of America ($382.93B) and being worth more than two Goldman Sachs ($244.09B). This highlights the significant growth and potential of stablecoins and the broader crypto market.
