US spot Bitcoin ETFs shed $462.7 million between September 8 and 11, with the damage concentrated on Thursday's $282.7 million, led by ARK Invest at $164.3 million. Grayscale and Fidelity were consistent sellers across the week and BlackRock's IBIT, which had led nearly every inflow session in August, posted redemptions on three of the four days. Spot Ethereum funds pulled in $197 million over the same stretch, which makes this look more like rotation between the two than a wholesale exit from crypto.
