Spot Bitcoin ETFs just posted their biggest 30-day vanishing act: $6.35B poof 💨

US-listed spot Bitcoin exchange-traded funds recorded their largest 30-day net outflow since launching in January 2024, shedding $6.35 billion over the trailing 30 trading days, according to data from Galaxy Research. The figure extends a sixth straight week of withdrawals and pulls cumulative net flow down to $53.4 billion from a $63 billion peak reached in October 2025. Galaxy Research noted that daily outflows are "still deepening day over day."

The withdrawals coincide with a broader pullback in Bitcoin, which was trading at $64,167 at the time of writing, down 17.4% over the past month. The asset has been pressured by macroeconomic factors, including rising US inflation and the ongoing war between the US and Iran, even as on-chain Bitcoin activity has neared record highs amid a surge in microtransactions.

BlackRock US head of equity ETFs Jay Jacobs told Cointelegraph on Thursday that daily outflows can be read in many ways and are not necessarily a signal of waning institutional appetite. "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 the firm's iShares Bitcoin Premium Income ETF (BITA), which launched on Wednesday. Jacobs added that volatility has not altered BlackRock's view of Bitcoin as a global, decentralized, nonsovereign monetary alternative. "Every asset class has volatility… we have over 450 exchange-traded funds within iShares," he said. "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."
