The stablecoin market capitalization has surpassed $300 billion as of October 3, 2025, reflecting a nearly 50% increase since the start of the year. This growth is largely driven by the passage of the GENIUS Act in July 2025, which introduced regulatory clarity for stablecoins in the U.S., attracting significant investment. Dollar-pegged stablecoins dominate the market, with USDT, USDC, and USDe holding the largest shares. Since the GENIUS Act's implementation, the market has seen an influx of nearly $50 billion. Industry experts and officials anticipate that the stablecoin market could expand to trillions in the coming years, as regulatory frameworks continue to evolve and investor confidence grows. The current market composition shows over 99.5% of stablecoins are pegged to the U.S. dollar, underscoring the currency's dominance in the sector.
