- Spot Bitcoin ETFs recorded $2.406 billion in net outflows for May 2026, the weakest month since November 2025.
- BlackRock’s IBIT led with $440.3 million in outflows, the largest single-fund exit in May.
- MSBT was the only spot Bitcoin ETF to record net inflows.
U.S. spot bitcoin exchange-traded funds extended their downward trend for the eleventh day in a row.
BlackRock Leads Others in Major Bitcoin ETF Exodus
Bitcoin ETFs reported $483.8 million in net outflows on Monday, with $440.3 million leaving BlackRock’s IBIT, according to data from SoSoValue.
Morgan Stanley’s MSBT contributed $6.14 million, the day’s only net inflow.
The U.S. bitcoin funds lost a total of $3.45 billion over the last 11 trading days, marked by consecutive net withdrawals.
The funds recorded a monthly net outflow of $2.43 billion in May, the largest since November 2025.
This is an extension of the negative flow pattern that was observed in May.
According to Bitrue researcher Andri Fauzan Adziima, rising inflation, higher Treasury yields, and cooling expectations for interest rate cuts drove May ETF outflows, with institutions diverting funds from crypto ETFs to AI-related companies.
The current negative trend is a cautious, risk-averse action, not a rejection of Bitcoin.
Adziima also blamed the Bitcoin drop on recent US-Iran tensions and Strategy’s first BTC sale in years, claiming that the timing of the prospective sale announcement was terrible and contradicted the company’s “buy and hold” narrative.
Extended Record Outflow Streak Plagues Every Bitcoin ETF
Recent market data confirms that the ongoing institutional selling has established an unprecedented negative trend.
The continued redemptions set a record for spot Bitcoin ETF outflows per day.
This painful daily bleeding saw it’s latest 9-10 consecutive trading sessions of negative fund flows.
This day-long trend of liquidations came on top of nearly $3 billion wiped out in the regulated digital asset wrappers.
The nonstop institutional distribution has caused a significant decline in short-term price sentiment and has reduced support for spot prices.
This ongoing supply from these funds is undermining investor confidence, and consequently, market participants are very cautious.
The steep drop points to an intense short-term pattern where institutions are de-risking across key crypto products.
People are selling shares in a frenzy, so fund managers end up having to sell real spot holdings too, not just paper entries.
Broader Institutional Rotation Triggers Sharp Bitcoin ETF Pullback
That dramatic change in fund flows also suggests a substantial institutional retreat during Q2 2026.
Since May 7, the net outflow from the spot Bitcoin Exchange Traded Funds (ETFs) category has been roughly $4 billion.
This significant contraction in capital shows clearly that institutional demand for premium digital assets has cooled off.
And this downturn marks the steepest monthly financial drawdown for the spot Bitcoin ETF segment since January 2026.
Given the present pessimistic attitude and sustained ETF outflows, Adziima believes the crypto market will consolidate further and test lower levels in the short term.
