US spot Bitcoin ETFs posted $201.8 million in net outflows on Friday, led by ARK 21Shares, ending a 9-day inflow streak and pulling total fund assets back below $100 billion. At 1.42 standard deviations below the 30-day average daily flow of $109.3 million, this is an elevated single-day outflow but not historically extreme. One-day reversals after multi-day inflow runs are a recurring pattern and carry less signal than a sustained multi-day outflow sequence would.
