Bitcoin ETF Outflows Hit $635M as IBIT Leads

• U.S. spot Bitcoin ETFs recorded $635M in net outflows.
• BlackRock’s IBIT led with $285M in withdrawals.
• Spot Ethereum ETFs saw $36.30M in net outflows.

U.S. spot Bitcoin ETFs saw a sharp wave of withdrawals on May 13, with total net outflows reaching $635 million, according to SoSoValue data. The move marked a notable shift in investor activity as several major funds faced selling pressure.

BlackRock’s IBIT led the day’s Bitcoin ETF outflows, recording $285 million in net withdrawals. As one of the largest and most closely watched spot Bitcoin ETFs, IBIT’s movement often draws attention from traders and market analysts.

The outflows suggest that some investors may be taking profits, reducing risk, or reacting to short-term market uncertainty. While daily ETF flows do not always show the full market trend, a large withdrawal figure can influence sentiment across the crypto sector.

Bitcoin ETF Outflows Led by BlackRock’s IBIT

BlackRock’s IBIT has often been seen as a strong institutional gateway into Bitcoin. However, the latest Bitcoin ETF outflows show that even leading funds can experience heavy redemptions during volatile periods.

The $285 million outflow from IBIT accounted for a major share of the total $635 million withdrawn from U.S. spot Bitcoin ETFs. This could point to cautious positioning among institutional investors or a broader pause after recent market activity.

Other Bitcoin ETFs also contributed to the total outflows, showing that the selling pressure was not limited to one product.

Ethereum ETFs Also See Net Withdrawals

Spot Ethereum ETFs also faced negative flows on May 13. U.S. spot Ethereum ETFs recorded total net outflows of $36.30 million.

BlackRock’s ETHA posted the largest single-day Ethereum ETF outflow, with $21.10 million leaving the fund. Although smaller than Bitcoin ETF outflows, the Ethereum ETF withdrawals show that investor caution extended beyond Bitcoin.

For now, ETF flow data remains an important signal for crypto markets. Strong inflows can support confidence, while large outflows may create short-term pressure. Investors will likely watch the next few trading days closely to see whether this was a one-day move or the start of a broader trend.
