In a stunning move that’s sending shockwaves through the crypto market, clients of BlackRock, the world’s largest asset manager, have offloaded $473.72 million worth of Bitcoin (BTC) in a single day—the biggest USD-denominated outflow since the firm’s spot Bitcoin ETF launched.

The massive sell-off, confirmed via on-chain data and ETF flow trackers, marks a sharp reversal from the relentless institutional buying that propelled BTC past $90,000 earlier this month. Today’s exodus shatters the previous record of $329 million set in late October, raising fresh questions about near-term price stability.

Scale : $473.72M in BTC sold — ~5,200 BTC at current prices.

Context: Comes just 48 hours after BlackRock’s iShares Bitcoin Trust (IBIT) hit a new AUM peak of $52.1 billion.

Market Impact : BTC dipped 2.8% within hours of the flow data surfacing, now trading at $88,900.

Analysts are split: some see profit-taking after the post-election rally, while others warn of macro jitters—rising bond yields and a stronger dollar—as the real trigger.

One thing’s clear: when BlackRock clients move this much BTC, the market listens.
