"Big Short" Money Manager Michael Burry Just Bet Against Nvidia and Palantir. Is He Calling the Top of the Artificial Intelligence (AI) Boom?

Michael Burry's Scion Asset Management has reportedly taken new short positions by purchasing put options on semiconductor giant Nvidia and data mining specialist Palantir Technologies, signaling a belief that the artificial intelligence (AI) sector is overvalued and due for a correction. Burry's rationale centers on the companies' high price-to-sales valuations, particularly Palantir's 124 P/S ratio, drawing parallels to the dot-com bubble, and noting broader market indicators like the Shiller CAPE ratio. However, the article also highlights strong ongoing investment in AI infrastructure by major tech firms such as Meta, Microsoft, and OpenAI, suggesting robust long-term demand for Nvidia's GPUs and Palantir's services, which could position Burry's bet as a short-term view against a powerful secular trend.

Analysis

Michael Burry's Scion Asset Management initiated new short positions in Q3 on Nvidia (NVDA) and Palantir Technologies (PLTR) via put options, signaling a belief in an impending AI sector correction. This move, reminiscent of his subprime crisis foresight, is driven by concerns over high valuations. Palantir's 124 P/S multiple significantly exceeds dot-com era peaks, while Nvidia's P/S of 29 approaches historical bubble thresholds, further pressured by increasing competition from AMD and Broadcom.

Burry's bearish stance is contextualized by broader market indicators, including a Shiller CAPE ratio near 40 and a Fear & Greed Index at 29, historically associated with market corrections. Conversely, the article highlights robust, ongoing AI infrastructure investments from hyperscalers like Meta, Microsoft, and OpenAI, committing billions to procure Nvidia GPUs and other AI resources, suggesting a powerful secular trend.

While acknowledging Palantir's "well overbought" valuation and potential for a near-term pullback, the analysis notes continued bullishness on its long-term ability to secure significant public and private sector business. Nvidia is also seen as well-positioned to capitalize on the unfolding AI infrastructure era. The article's overall tone remains cautious, yet mildly positive on the long-term AI narrative, suggesting Burry's bet might be a short-term tactical play.

Key Decisions for Investors

• Investors should consider Burry's short positions as a potential signal for short-term volatility or a near-term correction in highly valued AI stocks like Palantir.
• Evaluate the long-term investment theses for Nvidia and Palantir by weighing their current valuations against sustained AI infrastructure spending and evolving competitive landscapes.
• Monitor broader market indicators such as the Shiller CAPE ratio and Fear & Greed Index for signs of systemic overvaluation or shifts in market sentiment.
• Assess individual company fundamentals and competitive positioning within the AI sector to differentiate between speculative froth and durable long-term growth drivers.
