币界网报道：Circle's stock (NYSE: CRCL) surged 34% on Wednesday with an additional 6% after-hours gain after the U.S. Senate passed the GENIUS Act, a landmark bill establishing regulatory frameworks for dollar-backed stablecoins. The stock closed at $199.59, peaking at $211.87 post-market, marking a 540% rise since its June 5 debut. The bill, requiring House approval and President Trump's signature, outlines rules for U.S. firms issuing fiat-backed stablecoins, signaling bipartisan crypto payment regulation. Circle CEO Jeremy Allaire hailed it as a breakthrough for U.S. competitiveness, while Trump praised it as positioning America as the "undisputed leader in digital assets." USDC issuer Circle, benefiting from regulatory clarity, saw trading volume spike to 60M shares, with its market cap surpassing $48B. Bernstein analysts noted the bill would redirect stablecoin innovation to U.S. players, treating them as "digital cash" for mainstream adoption.
