'Choke Point'—Bitcoin's $77B Coinbase ETF Warning Shocks Markets

Forbes reports that roughly $77 billion—about 84% of the $91.7 billion U.S. spot bitcoin ETF market—is custodied at Coinbase Prime, creating a concentration risk that has market participants and regulators talking. The piece contrasts growing institutional demand (new products from BlackRock, Morgan Stanley, Goldman Sachs and others) with fears that a single-custodian failure or regulatory action could trigger systemic stress. The article notes Coinbase’s recent conditional OCC national trust charter (April 2) increases regulatory oversight but also folds custody exposure into the federal banking perimeter. Analysts lay out both bullish scenarios (large advisor flows lifting bitcoin toward much higher targets) and bearish scenarios (operational, fiduciary or rehypothecation risks). The net takeaway: institutional adoption is bullish for flows, but custody concentration is a material structural risk to monitor.
