Bitcoin spot ETFs suffered $635.5M in outflows on October 22, their largest withdrawal since June 2025. BTC slipped toward $81,000, a key ETF investor cost basis.

  • BlackRock’s IBIT led selling with $254.1M outflows.
  • Fidelity’s FBTC and ARKB added another $326.9M in withdrawals.
  • The outflow erased over $1.05B of inflows from the prior two sessions; Switzerland’s BBIT fund is expected to begin trading in November.

LaunchBar verdict: $81K is now the battlefield. Holding it could trigger stabilization, but a clean breakdown risks accelerating ETF-driven panic. Traders should watch daily flows before chasing any bounce.
