Bitcoin ETFs Post Record Nine-Day Outflow Streak

US-listed spot Bitcoin exchange-traded funds (ETFs) posted their longest outflow streak since launch, extending withdrawals as institutional demand for Bitcoin exposure weakened.

Spot Bitcoin ETFs recorded another $223 million in net outflows on Thursday, marking the record nine-day outflow streak since the funds launched in 2024, according to data from Farside Investors.

The latest streak surpassed the previous record eight-session outflow run recorded in February 2025, though its roughly $2.84 billion in cumulative withdrawals remains below the $3.2 billion lost during the earlier selloff.

The outflows suggest institutional demand for Bitcoin exposure is weakening through the ETF channel, and come as major corporate holders such as Strategy face renewed pressure even as some new altcoin products like Hyperliquid (HYPE) ETFs continue attracting investor interest.

BlackRock’s IBIT leads the outflows at $2 billion

BlackRock’s iShares Bitcoin Trust (IBIT), the largest US spot Bitcoin ETF by assets, accounted for a massive share of losses during the nine-session outflow streak.

The fund recorded roughly $2.04 billion in cumulative outflows between May 15 and Thursday. As Cointelegraph reported, a $527.8 million withdrawal on May 27 marked IBIT’s second-largest daily outflow on record, narrowly below the $528.3 million record posted on Jan. 30, 2025.

Despite the selling pressure, BlackRock’s Bitcoin ETF remains the dominant US spot Bitcoin fund by assets under management. IBIT held roughly 792,000 BTC as of market close on Wednesday, representing about 62% of all US spot Bitcoin ETF holdings, according to Wallet Pilot data.

HYPE ETFs buck the broader slowdown

While spot Bitcoin ETFs face sustained selling pressure, newly launched HYPE ETFs have continued attracting fresh capital from investors.

The products recorded steady inflows between May 12 and Thursday, with cumulative net inflows rising above $100 million, according to SoSoValue.

Other altcoin funds such as spot XRP ETFs also recorded steady gains over the period, totaling roughly $120 million in net additions between May 4 and Thursday.

The divergence underscores a shift in crypto fund flows, with investors pulling back from Bitcoin and Ether ETFs while newer products tied to tokens such as Hyperliquid’s HYPE continue to attract inflows.

US spot Ether ETFs have also faced persistent selling pressure, logging 13 consecutive days of outflows between May 11 and Thursday, with cumulative losses of roughly $694 million.
