a16z Highlights $9 Trillion Stablecoin Market in 2025, Explains Arc Investment Thesis

According to a16z Crypto, stablecoin transaction volume reached approximately $9 trillion in 2025, positioning stablecoins on par with global payment networks like Visa and PayPal. The total supply of U.S. dollar-denominated stablecoins exceeded $270 billion, with cross-border payments, B2B settlements, and foreign exchange trading emerging as primary use cases.

a16z Crypto stated that it is backing Arc as blockchain infrastructure evolves from application-layer finance toward a system-level economic operating system. The firm believes only a limited number of public blockchains will ultimately serve as the foundation for on-chain economic systems as global finance continues to migrate on-chain.
