Spot Bitcoin ETFs suffered their worst month on record in June, posting $4.5 billion in net outflows that sharply outpaced the $1.25 billion Strategy is authorized to raise through its new Bitcoin monetization program. The scale of withdrawals pushed year-to-date net outflows for 2026 to roughly $5.5 billion, cutting cumulative net inflows since launch to about $51.2 billion, according to SoSoValue. The downturn highlights a clear shift in sentiment toward Bitcoin ETFs, even as market attention remains focused on Strategy’s evolving capital strategy.

IBIT Drives the Decline as Holdings Fall Below Last Year

BlackRock’s iShares Bitcoin Trust (IBIT) accounted for about 79% of June’s withdrawals, recording $3.55 billion in net outflows, according to Farside Investors. The concentration of redemptions within IBIT added pressure across the broader Bitcoin ETFs landscape. SoSoValue data shows cumulative net inflows into US spot Bitcoin ETFs have risen 4.6% from about $49 billion a year earlier, yet CryptoQuant reports the funds now hold less Bitcoin than they did at this time last year. Julio Moreno noted that total holdings across US spot Bitcoin ETFs have fallen below 1.25 million BTC, reinforcing the view that overall demand continues to weaken.

Strategy’s Monetization Program Sparks Mixed Market Reaction

Strategy’s announcement of its Bitcoin monetization program on Monday marked a significant shift in its capital framework, aimed at supporting dividend obligations tied to preferred securities. The move drew mixed reactions, with some investors welcoming added flexibility while others questioned the long-term sustainability of the structure and suggested the company could ultimately sell more than $1.25 billion.

Market volatility followed. Strategy’s Class A common stock (MSTR) surged as much as 12% to above $90 before reversing and closing at $86.93 on Tuesday, down 6.2%. Meanwhile, preferred stock (STRC) traded higher at $84.86, according to Yahoo Finance. The developments added another layer of uncertainty to a month already defined by historic outflows from Bitcoin ETFs.
