Bitcoin ETFs experienced their worst 13-day outflow streak since 2024, losing $4.4 billion (59,400 BTC) during the period from May 15 to June 3, 2026. According to Galaxy Research, this streak set new records across multiple timeframes: 7 days: $2.78B and 39,300 BTC, 10 days: $3.06B and 42,900 BTC, and 20 days: $5.42B and 73,100 BTC. The outflows effectively erased the year's net inflows, pushing them back into negative territory, though cumulative net inflows remain at $55 billion. As reported by Bloomberg Senior Analyst Eric Balchunas, the streak ended on June 5 with a modest $3.05 million inflow, marking the first positive flow after 13 consecutive days of outflows. Total assets under management in bitcoin ETFs fell to $80.40 billion from $104.29 billion at the start of the streak, with holdings dropping to 1.277 million BTC, about 7.2% below the October 2025 peak.
Institutional Bitcoin demand has collapsed to a record low, with combined buying across ETFs, corporate treasuries, and miners turning more negative than at any point since 2020. According to Capriole Investments data shared by analyst Charles Edwards, the firm's Net Institutional Buying metric fell to -464%, its deepest reading since the series began in 2020. The metric aggregates flows across spot ETFs, corporate treasuries, and Bitcoin miners, with all rate-of-change components dropping below zero, including the ETF line sliding to -0.0126%, the lowest on the chart. Historically, readings of this negative have signaled aggressive distribution, with the data suggesting institutions are now reducing exposure faster than at any prior point in the current cycle. A return to positive territory would require sustained net buying from at least one major cohort, until then pointing to broad institutional outflows rather than accumulation.
Professional investors significantly reduced their Bitcoin exposure during Q1 2026, with total holdings declining by 52.5K BTC from 313K BTC to 261K BTC, representing a 17% decline. According to a recent report from CoinShares, this reduction in professional holdings was primarily driven by hedge funds and brokerages, with hedge funds and brokers accounting for 95% of the reduction. The bulk of selling came from hedge funds, which cut positions by 31,400 BTC (39%) and brokerages, which reduced by 18,800 BTC (53%). Notably, much of the brokerage selling came from Morgan Stanley and Jane Street, with Morgan Stanley exiting its 8.3K BTC position likely due to the launch of its own Bitcoin ETF, while Jane Street reduced 10.8K BTC. The timing of this sell-off coincided with broader market weakness, as Bitcoin traded at $61,005 at publication, down about 2.7% on the day and roughly 25% over the past month, with the market cap standing near $1.22 trillion.
Glassnode data confirms the broad-based decline in institutional exposure, with aggregate spot ETF holdings peaking near $160 billion in autumn 2025 when Bitcoin set a record high above $126,000. Since then, balances have fallen across nearly every issuer, from BlackRock's IBIT to Grayscale GBTC, with total holdings falling to around $75 billion by June 2026. US spot ETFs posted 13 straight days of net outflows through early June, shedding about $4.3 billion according to recent flow data. This broad-based unwind shows the pressure is not isolated to one fund, but spans the issuers that absorbed the heaviest inflows during the 2024 and 2025 rally. The selling has drained spot Bitcoin ETF balances since their autumn 2025 peak, with the decline reflecting lower prices rather than redemptions, though recent flow data removes this ambiguity.
The selling pressure has spread to large holders, with new whale wallets realizing roughly $2.5 billion in losses as Bitcoin dropped from the high $70,000s toward $60,000. According to CryptoQuant data, older whales stayed close to flat, indicating the pain is concentrated among recent, higher-cost buyers who overlap heavily with institutional money that entered through ETFs. BTC traded near $61,005 at publication, with a hold above $60,000 marking the nearest psychological support. A break below it could open the door to the low $50,000s, deepening the current capital drain. Reclaiming the $70,000 area would weaken the bearish case and suggest flows are stabilizing, with the path now hinging on whether macro pressure eases enough to slow institutional redemptions. Until net flows turn positive again, sellers hold the advantage in the current market environment.
