Bitcoin ETF Outflows: BlackRock Sold $317M BTC as BTC Drops
BlackRock’s spot Bitcoin ETF (IBIT) faced renewed selling pressure after clients sold about $317.1M worth of Bitcoin, according to Arkham Intelligence. The activity sparked fresh outflows from addresses linked to the fund.
Despite this selling, BlackRock still holds roughly $64.34B in BTC, bought at an estimated average price of $83,200.
At the market level, U.S. spot Bitcoin ETFs recorded a combined $290M net outflow on May 15. None of the 12 approved Bitcoin ETFs posted positive flows that day, breaking a six-week inflow streak. On a weekly basis, spot Bitcoin ETFs saw about $1B in net outflows, following prior inflows of roughly $3.4B.
Flow timing was sharp: Monday saw modest inflows ($27.29M), but Tuesday outflows hit $233.25M, Wednesday worsened to $635.23M. Thursday briefly improved with $131.31M in inflows, then Friday saw another $290.42M exit, leaving a roughly $1B loss for the week.
The broader risk-off move also hit Ethereum ETFs: U.S. spot Ethereum ETFs logged $65.65M net outflows on May 15 for the fifth straight withdrawal day.
Price pressure accompanied these Bitcoin ETF outflows: BTC fell 3.2% over 24 hours, slipping back toward the $78,000 range after briefly trading above $82,000. The drop reportedly led to over $500M in losses for leveraged bulls.
For traders, these Bitcoin ETF outflows signal near-term downside risk and heightened volatility, with potential follow-through if outflows persist.
Bearish
The article points to clear negative flows in Bitcoin ETF products. BlackRock’s IBIT saw about $317.1M in reported client BTC selling, and U.S. spot Bitcoin ETFs recorded a $290M net outflow on May 15 with zero of the 12 ETFs showing positive flows—breaking a six-week inflow streak and turning the week into roughly $1B of net outflows. Historically, such synchronized outflows tend to coincide with risk-off positioning: market makers and allocators reduce crypto exposure, liquidity thins, and dips become more self-reinforcing.
Additionally, Ethereum ETFs seeing $65.65M outflows on the same day suggests the move is not coin-specific but part of a broader “de-risking” across crypto. That aligns with the reported BTC drawdown (back toward $78k) and large leveraged liquidation losses (> $500M). When leverage unwinds, it often creates short-term downside momentum as forced selling pressure meets reduced bid support.
Short term: expect volatility to remain elevated, with bears able to press if ETF outflows continue for multiple sessions.
Long term: if this outflow wave stabilizes and inflows eventually resume, the market could absorb the selling and recover; however, until flows turn, rallies may face selling pressure from institutions rotating to cash or lower risk assets.
Overall, the combination of large ETF outflows, broken inflow streak, and leveraged liquidations skews the near-term setup bearish.
