BTC ETF AUM falls below $100B

TLDR

Spot Bitcoin ETF assets under management have dropped below 100 billion dollars for the first time since 2025, reflecting price damage and sustained outflows.

1. Spot BTC ETF AUM is around 96.9 billion dollars and recently fell below 100 billion dollars after peaking near 165 to 168 billion dollars in October.
2. The decline is driven by both Bitcoins price slide and several weeks of heavy ETF redemptions, leaving many ETF buyers sitting on unrealized losses.
3. The key signals now are whether outflows stabilize, how Bitcoin trades versus ETF cost basis, and whether flows rotate toward altcoin ETFs instead of BTC.

Deep Dive

1. Size Of The Drawdown

Aggregate spot Bitcoin ETF AUM is about 96.92 billion dollars, down from 113.13 billion dollars at the start of the week, a 14.33 percent decline over 1 to 7 February.

Reporting based on SoSoValue data notes that spot Bitcoin ETF assets recently fell below 100 billion dollars for the first time since April 2025, after reaching roughly 168 billion dollars at their peak in October, confirming that this is a significant round trip in institutional exposure size.

Over the same window, total crypto market cap has dropped sharply and Bitcoins price has pulled back, so part of the AUM loss reflects lower BTC prices rather than just money leaving the products.

2. Flows And Investor Behavior

Recent weeks have seen multiple large net outflow days from US spot Bitcoin ETFs, including daily redemptions in the hundreds of millions of dollars and weekly outflows in the 1 to 1.5 billion dollar range.

Year to date, spot Bitcoin ETFs are now mildly net negative on flows, with roughly 1.3 to 1.8 billion dollars more redeemed than added, even though cumulative inflows since launch remain very large. Articles also highlight that many ETF buyers are now underwater, because Bitcoin trades below the average ETF creation cost basis near 84,000 dollars.

Analysts quoted in these reports argue that most ETF capital is still sticky, with only a small percentage of total assets exiting so far, which suggests risk of continued pressure but not yet a full-scale institutional capitulation.

3. Signals To Watch Next

First, daily ETF flow data is critical: a shift from persistent net outflows to flat or modest inflows would be an early sign that institutional selling pressure is easing.

Second, watch where Bitcoin trades relative to the ETF cost basis around 84,000 dollars and on-chain realized price levels; regaining and holding above those zones would typically support renewed demand from ETF allocators.

Third, there are modest inflows into altcoin ETFs for Ether, XRP and Solana while BTC products lose assets, which hints at some rotation rather than a blanket exit from crypto risk, and that balance will help define which parts of the market lead in the next phase.

Conclusion

Bitcoin ETF AUM dropping below 100 billion dollars reflects a mix of price drawdown and sustained net redemptions after last years euphoria. If outflows persist while BTC trades below key cost basis levels, ETF pressure can reinforce a bearish environment. If flows stabilize and macro conditions improve, the same ETF channel can again act as a powerful lever for renewed institutional demand.
