CoreWeave shares extended their post-IPO slide after a six-month lockup on insider holdings expired on 14 Aug. The stock lost about 10% that day and is down roughly 22.5% over the past five sessions, as early holders rushed to sell into a market that has otherwise remained firm. CNBC reported that JPMorgan, Morgan Stanley and Goldman Sachs have been managing several CoreWeave blockchain operations. JPMorgan has already disposed of an estimated 5 million to 6 million shares in a block trade, while insider Cogen Jack sold about 3 million shares through Goldman Sachs, according to market participants. Some traders noted intraday attempts to stabilize the stock around the $100 level, but selling pressure persisted amid concerns that additional insiders may follow suit now that restrictions have lifted.
