Bitcoin ETFs Bleed $6.35B in 30 Days, Setting a Record Nobody Asked For 🩸

US-listed spot Bitcoin exchange-traded funds recorded their largest 30-day net outflow on record, shedding $6.35 billion over the trailing 30 trading days, according to Galaxy Research. The figure ranks as the heaviest of all 582 rolling 30-day windows the firm has tracked since the funds launched in January 2024. Galaxy Research said daily outflows are "still deepening day over day." The redemptions mark six consecutive weeks of withdrawals, bringing cumulative net flows across the complex down to $53.4 billion from a $63 billion peak in October 2025.

The selling has been concentrated in the largest product. BlackRock's iShares Bitcoin Trust (IBIT) accounted for roughly $4.51 billion of the 30-day outflows, making it the largest single source of redemptions, while the broader complex lost a combined $4.06 billion during June alone, the worst monthly figure on record, surpassing the prior monthly high of $3.56 billion set in February 2025, according to SoSoValue data. Grayscale's GBTC continued its structural leak, shedding $27 billion since launch, in part attributed to its 1.5% fee compared to IBIT's 0.25%. BlackRock's US head of equity ETFs Jay Jacobs told Cointelegraph on Thursday that single-day outflows can reflect portfolio moves rather than sentiment shifts. "What I think is maybe sometimes misunderstood by the market is that if we see a day of outflows, there could be a million reasons why. It could be someone selling IBIT and buying BITA," Jacobs said, referring to BlackRock's iShares Bitcoin Premium Income ETF (BITA), which launched on Wednesday. He added, "Every asset class has volatility… we have over 450 exchange-traded funds within iShares. So we see inflows and outflows every day across a wide range of assets from large cap, small cap, Bitcoin, gold, etc. So in the short term, it's absolutely not something that changes the way we view the asset or the utility of the asset."

Bitcoin was trading near $64,167 at the time of writing, down 17.4% over the past month and roughly 49% below its $126,080 record set on October 6, 2025. The asset has been pressured by rising US inflation, renewed geopolitical tension, and a broader risk-off shift that pushed weekly outflows from $1.72 billion in the week ending June 5 to about $226 million last week. Total net assets across US spot Bitcoin ETFs have fallen to roughly $72.6 billion, a decline of about 57% from the $169.5 billion peak in October 2025, with the funds holding a combined 1.24 million $BTC as of Tuesday, according to WalletPilot data. Strategy, the largest corporate Bitcoin holder, bought roughly 3,600 $BTC in June, down from about 25,000 in May and more than 50,000 in April, and recorded a net sale of 32 $BTC earlier in the month. Not every crypto ETF bled during the stretch: Solana ($SOL) ETFs drew $113.34 million in inflows over the 30-day window before later posting roughly $786,580 in June outflows, XRP ($XRP) ETFs pulled in $59.46 million during June, and Hyperliquid ($HYPE) ETFs led with $161.05 million in monthly inflows, while Ethereum ($ETH) ETFs shed $528.99 million in June.
