Coinbase Global jumped 7.1% after JPMorgan upgraded its rating from Neutral to Overweight, citing stronger revenue prospects from its Base blockchain platform. The bank expects 30% quarter-over-quarter growth in transaction-related income and expanding ETF-driven trading volumes across North America. Analysts noted Coinbase’s improving fee structure and growing institutional custody demand as key catalysts for margin expansion. The upgrade follows sustained crypto-market recovery this month, reinforcing sentiment that Coinbase remains a central infrastructure player in the digital-asset ecosystem.
