- Across all US spot Bitcoin ETFs that day, net flows were roughly ?$372.8 million, extending a five?day streak of redemptions, per the same update.

Deep Dive
1. IBITs Record Day
IBITs largest single?day redemption, about $523.2 million, occurred on 18 Nov and was highlighted in todays coverage as a new record for the fund since its January 2024 debut. That session also marked IBITs fifth straight day of outflows, reflecting waning risk appetite amid a broader drawdown in crypto prices, per a market report.
Analysts noted that many spot Bitcoin ETF buyers have an average cost basis near $90,146%%CKPROTECTED2%%, so price retests around that level can trigger redemptions as investors de?risk, the report above added.
A record outflow from the largest BTC ETF is a visible risk?off signal. If outflows persist, they can reinforce negative momentum and keep liquidity thin.
2. Market?Wide Flows
US spot Bitcoin ETFs collectively posted about ?$372.8 million in net flow on the same day, extending a five?day run of net redemptions, per the update above. Several outlets framed this as part of a broader November soft patch for crypto ETPs, with sentiment shifting more defensive as prices fell and hedging costs rose, as covered in another news round?up.
Sustained multi?day net outflows can pressure price and dampen bounces. A single strong inflow day would be an early sign of stabilization.
3. ETH Funds Context
Spot Ethereum ETFs also showed outflows around this period, with coverage flagging about $165 million out of BlackRocks ETHA on the day, though the record callout was specific to IBIT, per a news brief. That divergence suggests BTC flows were the primary driver of the headline record outflow narrative.
BTC ETF flows still anchor crypto market sentiment. ETH flows matter, but the largest BTC products behavior tends to set the near?term tone.
Conclusion
Todays reports point to a record one?day outflow at BlackRocks IBIT, alongside another day of net redemptions across US spot Bitcoin ETFs. The combo of price weakness near investor cost bases and defensive positioning likely amplified flows; stabilization would require a decisive shift back to net inflows or a durable price base. If you meant non?crypto ETFs, say which region or fund type and I can check those specifically.
