U.S. spot Bitcoin exchange-traded funds (ETFs) experienced a significant reversal on May 13, with net outflows totaling $635 million. This marks one of the largest single-day redemptions in recent months and highlights renewed selling pressure amid Bitcoin’s trading range near $79,000–$80,000.
According to data from SoSoValue, BlackRock’s iShares Bitcoin Trust (IBIT) led the exodus, shedding $284.69 million. The outflow underscores that even dominant products are not immune to short-term profit-taking or portfolio rebalancing.
Other major funds likely contributed to the broader decline, though specific breakdowns for issuers like Fidelity’s FBTC or ARK’s ARKB were not immediately detailed in initial reports.
Total assets under management for U.S. spot Bitcoin ETFs stood at $105.01 billion following the session, reflecting the scale of the industry despite the daily dip. This comes after a strong period of inflows in early May, including multi-hundred-million-dollar positive days that pushed weekly and monthly totals into positive territory.
Ethereum ETFs also saw outflows, with $36.3 million leaving the products. BlackRock’s iShares Ethereum Trust (ETHA) accounted for a substantial portion at roughly $21.1 million. The parallel selling in both major crypto ETFs suggests broader institutional caution rather than a Bitcoin-specific event.
Historical Perspective
While notable, the $635 million figure is not an all-time record. Larger single-day outflows have occurred during periods of heightened volatility, such as approximately $1.01 billion in February 2025 and around $672 million in December 2024.
Earlier 2026 saw days exceeding $800 million during sharp price corrections. Recent weeks had been calmer, with outflows typically in the $100–300 million range before this spike.
ETF outflows often coincide with profit-taking after rallies, macro uncertainty, or capital rotation into altcoins or traditional assets. Bitcoin has traded in a relatively tight band recently, lacking a strong directional catalyst to sustain aggressive buying.
Despite the daily setback, cumulative net inflows for Bitcoin ETFs since launch remain robust at tens of billions of dollars. Long-term holders and institutional allocators continue to see spot Bitcoin ETFs as a core portfolio diversifier. Market observers will watch upcoming sessions closely for signs of stabilization or continued redemption pressure.
As of publishing, Bitcoin hovered near $79,500—reacting mildly to the flow data. While CPI and PPI data are now released, investors remain focused on macroeconomic indicators, regulatory developments, and potential catalysts for renewed demand.
