Central bank wave grows: ECB's Panetta now warns of AI valuation correction risk

Fabio Panetta, a senior figure at the European Central Bank, has warned — according to a summary of his remarks to Bloomberg Economics — that optimistic valuations of AI companies could end in a market correction.

According to Crypto Briefing's account of remarks Panetta gave to Bloomberg Economics, he has warned that today's optimistic valuations of AI companies could end in a market correction if the enthusiasm proves excessive (920dc46d). The remarks were reportedly given to Bloomberg Economics, but neither the interview itself, speaking notes, nor direct quotes have been published in the available source material. What exists is thus a secondary account of a message, not a primary source. The warning follows a string of official cautions about elevated AI valuations — but without direct quotes or primary sources, it remains unclear how detailed and how conditional Panetta's warning actually was.

What is actually reported

According to Crypto Briefing, Panetta highlighted the possibility of a market correction should the valuations prove overly enthusiastic (920dc46d). The remarks reportedly came in a context where Panetta, per the same source, joins a series of similar warnings from financial analysts and industry experts who are increasingly skeptical of the rapid value gains in the AI sector.

Two things are worth noting. First, this is a summary from a single source, not a transcribed interview or a public speech. Second, the message is conditional — the correction risk assumes that the valuations prove excessive. This is not a prediction that a collapse is imminent, but a risk warning tied to a scenario that Panetta, according to the source, considers real enough to be worth flagging.

A broader wave of central bank warnings

Panetta's warning fits a pattern that has been visible for some time. In October 2025, IMF chief Kristalina Georgieva warned that AI valuations were approaching dot-com-era levels. "Valuations are heading toward levels we saw during the bullishness about the Internet 25 years ago," she said, warning that a sharp correction could tighten financial conditions, weaken world growth, and hit developing countries particularly hard (5a17aaac).

The same report noted that the Bank of England had warned of the risk of a "sharp market correction," that ECB policymakers had expressed concern, and that the Reserve Bank of Australia had pointed to vulnerabilities in the markets that same month (5a17aaac). It is important to hold this as background, not as confirmation of Panetta's September remarks — Georgieva's warning is almost a year older and applies to a different point in the market cycle.

What Panetta adds, then, is not a new theme but a reinforcement from a central actor: a top ECB official with proximity to monetary policy has now aligned himself with what the IMF, the Bank of England, and other central banks have already signaled.

A separate appearance the same day: AI and inflation

The same day, September 21, 2026, Panetta took part in an event hosted by the National Bank of Ukraine. There he argued, according to Reuters via the Miami Herald, that central banks need to understand who benefits from AI-driven gains, because their distribution will help shape aggregate demand and inflation (9410ee4f).

The source suggests that AI could be both inflationary and disinflationary, depending on whether the technology primarily creates new tasks or primarily automates existing ones. This is a different perspective from the valuation warning — it is not about asset prices, but about AI as a macroeconomic force. Taken together, the two appearances give the impression that Panetta is working on AI from several angles: partly as a financial stability risk through valuations, partly as a structural driver of demand, output, and inflation dynamics.

The prediction market and the Anthropic figure

Crypto Briefing also attaches a prediction-market figure to the story: the probability of Anthropic reaching a valuation of $600 billion by the end of 2026 is, according to the outlet's data (powered by Vera), just 1.8 percent (920dc46d). This figure should be treated with caution. It comes from a single source, has not been independently confirmed, and the causal link the source suggests between Panetta's remarks and market movements is asserted, not documented.

Open questions

• Panetta's exact role. Crypto Briefing describes him as a member of the ECB's Executive Board, while Reuters via the Miami Herald describes him as a member of the ECB's Governing Council and governor of the Bank of Italy. The available sources do not resolve this discrepancy.
• Missing primary source. No transcript, speech text, or the actual Bloomberg interview is available in the public source material. This limits how precisely the message can be conveyed.
• Level of detail and timing. The specifics of what Panetta actually said beyond the summary — including whether he emphasized particular valuation metrics, sectors, or time horizons — cannot be verified from what is available.

What remains is a clear core message: a central figure in European monetary policy shares the concern that the IMF, the Bank of England, ECB colleagues, and the Reserve Bank of Australia have already signaled — that the AI sector's valuations rest on an optimism that will not necessarily hold, and that a correction is then a real risk. How nuanced and conditional Panetta's warning actually was, we do not yet know.
