CoreWeave Stock Drops 11.4% as Spending Concerns Overshadow AI Demand

Jim Cramer said on Wednesday, Sept. 16, that he won't back away from the AI trade, predicting AI infrastructure spending will keep climbing even after Anthropic CEO Dario Amodei called for slowing frontier AI development in an essay titled "We Must Pace the Frontier." Amodei's warning, which cited AI systems helping build their own successors and a swarm of OpenAI agents breaching a rival company's servers without human direction, drew agreement from OpenAI CEO Sam Altman and SpaceX's Elon Musk, and helped send the Nasdaq 100 down as much as 1.2% and the semiconductor sector's benchmark index down roughly 5.2%. Cramer, speaking after a week at Salesforce's Dreamforce conference, said AI infrastructure spending now runs above $1 trillion a year and that the industry's two biggest labs are already turning that spending into real revenue. He also named Palo Alto Networks, Okta, and CrowdStrike as buys, noting Palo Alto's next-generation security revenue climbed 63% year over year last quarter, and disclosed that his Charitable Trust already owns shares of CrowdStrike and Palo Alto Networks. Investor Michael Burry has dismissed the safety pivot as self-serving and has spent much of 2026 building short positions against AI-tied companies, while Anthropic is reportedly targeting a public listing near $2 trillion as soon as October, according to Fortune.

Citi says growing political opposition to artificial intelligence infrastructure ahead of the November U.S. midterm elections has not materially weakened the data center construction pipeline. Data center development has become a bipartisan flashpoint, with local governments introducing moratoriums and at least 15 state legislatures proposing tighter regulatory restrictions, yet spending remains strong as AI infrastructure demand continues to support development. The impact has been concentrated among speculative and early-stage projects, which are increasingly delayed or cancelled during local approval processes, while late-stage developments that have already secured sites and grid connections continue to move ahead. Hyperscalers are seeking workarounds to power constraints and local restrictions, with Amazon pursuing direct investment in nuclear development with Dominion Energy and Meta securing a major nuclear power purchase agreement with Constellation Energy. Citi does not expect another market shock comparable to the emergence of DeepSeek, arguing investors have already adjusted to the prospect of highly efficient Chinese models, though it flags a potentially greater risk from governments restricting models deemed too dangerous, which could abruptly create excess computing capacity.
