BlackRock Bitcoin ETF Records $10 Billion Trading Day Amid Sharp Selloff
BlackRock's spot Bitcoin exchange-traded fund registered its highest single-day trading volume on Thursday, with more than 284 million shares changing hands according to Nasdaq records. The activity represented over $10 billion in notional value, nearly tripling the fund's previous record of 169.21 million shares set on 21 November.
The surge in volume accompanied a sharp price decline. IBIT fell 13 percent to close below $35 per share, its lowest level since 11 October 2024. The fund has now declined 27 percent year to date, retreating from a peak of $71.82 reached in early October.
Thursday's session saw IBIT record outflows totalling $175.33 million, representing 40 percent of the combined $434.11 million withdrawn from the 11 spot Bitcoin ETFs tracked by SoSoValue. The fund, which holds physical Bitcoin and tracks the cryptocurrency's spot price, has served as a regulated access point for institutional investors seeking exposure to digital assets.
Bitcoin itself dropped to approximately $60,000 during Thursday's session, continuing a broader decline across cryptocurrency markets.
Options market data from MarketChameleon showed heightened defensive positioning. Put options with longer expiry dates, typically used to hedge against further declines, traded at a premium exceeding 25 volatility points above call options. This skew towards protective instruments reached record levels during the session.
The combination of extreme volume and falling prices often indicates capitulation selling, a phase in which long-term holders exit positions at a loss. Such episodes historically coincide with late-stage bear market activity, though sustained downturns can extend beyond initial selling peaks.
IBIT remains the largest publicly traded Bitcoin fund globally, holding physical coins as its underlying asset. The product launched as part of the first wave of spot Bitcoin ETFs approved by US regulators, attracting significant institutional capital during its initial months of operation.
Industry Impact and Market Implications
Thursday's trading activity in IBIT may signal a shift in sentiment among institutional holders who have used spot Bitcoin ETFs as their primary exposure vehicle. The record volume suggests a meaningful reallocation away from cryptocurrency assets within portfolios that previously maintained long-term positions through regulated products.
The options market skew indicates participants are prioritising downside protection over speculative positioning, a behavioural pattern typically associated with heightened uncertainty. If sustained, this defensive stance could influence liquidity conditions across both ETF and spot cryptocurrency markets.
For ETF issuers, concentrated outflow events test operational infrastructure and redemption processes, particularly when managing physical Bitcoin transfers to authorised participants. The ability of IBIT and competing products to handle large-scale redemptions without significant tracking errors will likely inform institutional confidence in these vehicles during volatile periods.
From a regulatory perspective, the episode demonstrates how spot Bitcoin ETFs function under stress conditions. Regulators monitoring these products will observe whether the funds maintain orderly markets and accurate pricing during sharp selloffs, information that could shape future approval decisions for cryptocurrency-linked financial products.
The price action may also affect miner economics, as Bitcoin's decline toward $60,000 approaches cost-of-production levels for some operations. Reduced institutional demand through ETFs could compound pressure on miners already facing profitability challenges following recent network adjustments.
