U.S. spot bitcoin exchange-traded funds extended their negative streak to an 11th consecutive day following monthly net outflows in May.

According to data from SoSoValue, the bitcoin ETFs posted $483.8 million in net outflows on Monday, led by $440.3 million exiting BlackRock's IBIT. The only net inflow of the day came from Morgan Stanley's MSBT, which added $6.14 million.

During the past 11 trading days of consecutive net outflows, the U.S. bitcoin funds shed a cumulative $3.45 billion. This is an extension of the negative flow trend seen in May, when the funds logged a monthly net outflow of $2.43 billion — the largest monthly outflow since November 2025.

"May's $2.43 billion ETF outflows were caused by rising inflation, higher Treasury yields, and fading hopes for interest rate cuts," said Andri Fauzan Adziima, Bitrue Research Institute's research lead.

The analyst said the dampened hopes for an improved macroeconomic environment have prompted institutions to withdraw funds from crypto ETFs and move to other assets, such as AI-related stocks.
