Tech giants are accelerating their layout in the stablecoin track, pushing it to become the core of digital financial infrastructure. In June 2025, Circle, the world's second-largest stablecoin issuer of USDC, listed on the New York Stock Exchange, with its stock price skyrocketing 168% on the first day. Meta also restarted its stablecoin plans, exploring payment scenarios for Facebook and WhatsApp. PayPal offers a 3.7% yield for PYUSD holders, and Stripe launched the programmable stablecoin USDB, covering enterprise accounts in 101 countries. Visa and Mastercard are facilitating offline consumption scenarios by linking stablecoin payment cards. On the regulatory front, the passage of the U.S. 'Genius Act' and Hong Kong's 'Stablecoin Regulations' paves the way for compliance, allowing tech giants to seize trillion-dollar markets in cross-border payments, DeFi, and AI proxy payments.
