A claim that BlackRock sold roughly $310 million worth of ether ricocheted across social media on Tuesday, igniting fast takes on what it might mean for crypto markets.
The post did not include verifiable documentation, and there was no statement from BlackRock to confirm a transaction of that size. Without a regulatory filing or official disclosure, the report remains unverified.
The post framed the move as a large sale of ETH, inviting speculation that the selling pressure came through exchange-traded funds or client accounts.
At the time of writing, neither BlackRock nor its iShares division had addressed the claim. Daily ETF flow reports and fund fact sheets typically update after the close, which means intraday chatter can run ahead of the data.
Crypto has been whipsawed by policy and liquidity headlines in recent weeks, including an earlier SEC move prompts pullback across several crypto ETF tickers.

Recent activity has sent mixed signals, from wallet trackers highlighting accumulation at major players to balance sheet repositioning elsewhere, such as when Tether quietly grabs 8888 bitcoin during market stress.

Those documents, not viral posts, will show whether there was a meaningful move in BlackRock’s ether exposure and whether any shift reflects client flows, internal rebalancing, or routine market making.
