Coinbase Global is positioning stablecoin payments as a core growth engine as it seeks to diversify beyond crypto trading fees. Chief Executive Officer Brian Armstrong has projected that the roughly $300 billion stablecoin market could expand tenfold by 2030, supported by wider use of digital dollars by banks, fintech firms and businesses for payments and treasury management. Coinbase receives slightly more than half of the economics generated by USDC through its partnership with issuer Circle Internet Group, while Bloomberg Intelligence estimated stablecoin-related revenue represented about 24% of Coinbase's second-quarter revenue. Armstrong has also maintained that Bitcoin could reach $400,000 by 2030, a target requiring a 420% gain from about $76,930. Bitcoin was down 5.4% over seven days and about 39% below its October 2025 record above $126,000. Armstrong said the latest downturn had passed the roughly one-year duration he associates with prior Bitcoin cycles, while analyst Jesse Myers cited historical post-halving gains and projected a possible path above Armstrong's target. U.S. spot Bitcoin ETFs attracted $986.9 million in the week ended Sept. 4 but recorded $166.9 million in net outflows in the current week, placing a three-week inflow streak worth about $3.8 billion at risk.
