Dire warnings on AI from Anthropic CEO Dario Amodei and OpenAI CEO Sam Altman could weigh especially heavily on CoreWeave, which Bernstein analyst Madison Rezaei called the most exposed name in the firm's coverage. Rezaei estimated that 25% of CoreWeave's existing active U.S. power, plus roughly 74% of its contracted power, sits in Tier 3 and Tier 4 markets, and said a slowdown in training development could trigger a pullback in demand for contracted, not-yet-sold rural power, though the take-or-pay backlog itself is not under threat. CoreWeave shares fell nearly 7% in pre-market trading, one of the worst slides in the AI stock patch. Amodei wrote in a 3,800-word essay on Saturday that fully addressing AI risks requires pacing the rate of capabilities advancement, and Altman said he agreed before posting on X early Monday that AI progress could go badly if control of the future is lost or power becomes too concentrated. CoreWeave carries about $27 billion in long-term debt alongside $6.3 billion in cash, and had rallied about 25% before the selling pressure, after second-quarter sales surged 112% year over year, adjusted operating profits more than doubled to $1.5 billion, and management raised full-year 2026 revenue guidance to a range of $12.4 billion to $13.2 billion on a $104 billion total revenue backlog.
