U.S. spot Bitcoin ETFs pull in $730 million, biggest one-day inflow in nine months

U.S. spot Bitcoin ETFs recorded $730 million of net inflows, the strongest single-day demand in nine months. The magnitude signals renewed institutional allocation and improved risk appetite, increasing the probability of tighter spot market liquidity and higher near-term volatility. ETF flow strength is closely watched as a real-time gauge of marginal BTC demand and can influence broader crypto sentiment and positioning.
