Bitcoin ETFs record $70.47M outflow

U.S. spot Bitcoin exchange-traded funds recorded $70.47 million in net outflows on Wednesday, May 21, extending a four-session run of withdrawals, according to an Investing.com market analysis published on May 22. The article said the four-day stretch totaled about $1.34 billion in redemptions through May 21, with BlackRock's iShares Bitcoin Trust and Fidelity's Wise Origin Bitcoin Fund accounting for most of the latest day's decline. BlackRock lists IBIT as an exchange-traded product designed to track the price of bitcoin, while Fidelity describes FBTC as a fund offering bitcoin exposure through brokerage and retirement accounts. ### Which funds drove the latest day of withdrawals? BlackRock's iShares Bitcoin Trust, trading under ticker IBIT, accounted for $61.45 million of the May 21 outflow, according to Investing.com. Fidelity's FBTC posted $10.12 million in net outflows on the same day, the report said. BlackRock says IBIT seeks to reflect bitcoin's price performance and gives investors exposure through an exchange-traded product. (au.investing.com) Fidelity says FBTC is its spot bitcoin fund for U.S. brokerage, trust and IRA accounts. ### How large was the broader pullback? Investing.com said the May 21 withdrawals were the fourth consecutive session of net outflows for the U.S. spot Bitcoin ETF group. (au.investing.com) The article put cumulative withdrawals over those four sessions at about $1.34 billion. Investing.com separately reported in another March analysis that Bitcoin ETFs had already lost about $4.5 billion in 2026 through that point, underscoring that the May outflows came after an already weak year for the category. (blackrock.com) That earlier article said IBIT alone had lost about $2.1 billion over a five-week stretch at that time. (au.investing.com) ### What are IBIT and FBTC, exactly? IBIT is BlackRock's spot bitcoin exchange-traded product, and BlackRock's fund page says it is designed to simplify access to bitcoin without requiring investors to hold the token directly. The page lists a 0.25% expense ratio and shows net asset value data updated for May 21, 2026. FBTC is Fidelity's Wise Origin Bitcoin Fund, which Fidelity says is intended for investors seeking direct exposure to bitcoin's price through a listed product. (investing.com) Fidelity's materials say the fund invests solely in bitcoin and carries a 0.25% expense ratio. ### Did the outflows line up with weaker bitcoin trading? Investing.com said in a separate May 22 market note that bitcoin was trading in the $76,700 to $77,500 range into the close of Friday, May 22. (blackrock.com) FXStreet also reported on May 22 that bitcoin was trying to hold $77,000 as near-term support amid broader risk-off sentiment. (digital.fidelity.com) Investing.com's May 22 analysis described the ETF outflows as evidence of weaker institutional demand, but that characterization came from the publication's own market interpretation rather than from BlackRock or Fidelity. ### Where can investors monitor the next data points? BlackRock's IBIT product page and Fidelity's FBTC fund materials continue to publish daily fund information including NAV, holdings details and prospectus documents. (investing.com) Those pages are the next reference points for investors tracking whether the May 21 redemptions continue into the following sessions. (blackrock.com) (au.investing.com)
