US Spot Bitcoin ETF Trading Volumes Sink 78% From October 2025 Highs
AI Market Summary
US spot Bitcoin ETF activity has materially cooled, with daily volumes down ~78% from the October 2025 peak and June 2026 posting record outflows. While AUM remains large ($78B–$100B), weaker flows and lower turnover indicate reduced marginal institutional demand and diminished marketmaking impulse versus 2025. Near-term, this points to softer liquidity conditions and less supportive flow-driven momentum for BTC.

Trading in US spot Bitcoin ETFs has cooled sharply. Glassnode data show daily volumes are down about 78% from the October 2025 peak, returning to levels more typical of late 2024 than last year's surge.
At the height of the boom, spot Bitcoin ETFs were turning over roughly $4.4 billion a day. The 30-day simple moving average has since fallen into a $650 million to $950 million range.
Flows have also deteriorated. June 2026 recorded the worst month on record for spot Bitcoin ETF outflows. While the pace of withdrawals has started to moderate, monthly net flows remain negative.
Even with weaker activity, assets under management are still estimated at $78 billion to $100 billion. Since launch, cumulative trading volume across spot Bitcoin ETFs has approached or exceeded $2 trillion.
Current volumes resemble Q4 2024, effectively rolling back market engagement by nearly two years. The institutional-adoption narrative that helped drive Bitcoin toward about $126,000 in 2025 has faded, replaced by a more subdued market tone.
Bitcoin's own price action reflects the shift. BTC has been consolidating between $58,000 and $65,000, well below last year's highs. Glassnode links the decline in ETF volumes to a lack of stabilized institutional conviction.
Major issuers remain in place. BlackRock and Fidelity still hold significant market share, but their role appears to have shifted from active catalysts to more steadystate portfolio management.
For investors, the drop in ETF volume sends mixed signals. Reduced activity weakens a key demand channel that helped propel BTC through 2025, indicating diminished buying pressure. At the same time, steady AUM suggests institutional exposure has not disappeared: $78 billion to $100 billion remains parked in these products even as Bitcoin trades more than 48% below its 2025 peak.
June's outflows are easing, but unless institutional conviction re-establishes in a sustained way, the $4 billion-a-day trading environment increasingly looks like a feature of a prior market cycle.
