Stablecoin issuer Circle, which filed for approval with the Securities Exchange Commission in January, has announced plans to move its headquarters to the Wall Street initial public offering (IPO) in 2025. To strengthen the market position of its stablecoin USDC, Circle has recently integrated USDC with the national payment systems of Brazil and Mexico, allowing businesses in both countries to access USDC in real time through local Financial Institution Groups without the need for international telegraphic transfers, thus speeding up the settlement of cross-border transactions. Although Circle is expanding its business, its market share is still being suppressed by Tether (USDT), which currently holds more than 70% of the market, compared to USDC's 20%. At the same time, Tether has hired Jesse Spiro, former head of regulatory relations for PayPal's blockchain business, to further strengthen its government affairs team. This series of moves by Circle is designed to enhance its competitiveness in the stablecoin market, especially in the rapidly growing digital dollar ecosystem.
