Citadel’s Griffin Warns AI Bubble as Credit Fears Rise
On.cc · 2 SOURCESabout 4 hours ago2 MIN

Summary
Citadel founder Ken Griffin said investors are “almost certainly” in an AI bubble, arguing that major economic shifts often come with speculative excess but that companies surviving the shakeout can still dominate for decades. His comments came as investors also focused on AI infrastructure financing risks after CoreWeave’s shares fell about 25% last week and some of its bonds traded at yields near 15%. Together, the two developments underscore a central market question: whether surging AI spending can generate enough cash flow to justify valuations and repay debt. Griffin has also shifted to a more constructive view of AI, saying it could create many new business models in the US even as it threatens white-collar jobs and erodes corporate moats
Key Points
- Griffin said at Citadel Securities’ annual conference in New York on Tuesday that investors are “almost certainly” in an AI bubble
- He said companies are still struggling to judge how much to spend on AI and how to turn bills from Anthropic and OpenAI into productivity gains
- Griffin compared the moment to the pre-crash internet era, saying some models were far-fetched, but survivors could lead markets for decades; he cited Amazon
- Separately, CoreWeave’s shares fell about 25% last week, while some bonds around October 14 saw yields jump to 15% amid market anxiety
- Goldman Sachs upgraded CoreWeave to “buy” on Monday but cut its target price to US$106 from US$139, while the stock closed at US$61.12
Why It Matters
For Hong Kong investors tracking US technology names, the story points to two linked risks: stretched expectations for AI growth and the financing strain behind the build-out of chips and data centres. If capital markets become less willing to fund AI infrastructure at reasonable costs, sentiment toward related equities could stay volatile even when long-term demand remains strong.
