Michael Burry Escalates Nvidia Puts, Micron Short Bets

A Bearish Bet Against the AI Trade

Investor Michael Burry, best known for his early call against subprime mortgages, has doubled down on skepticism toward the artificial intelligence chip boom. His most recent portfolio disclosure shows an increase in put options against Nvidia and a new short position against Micron and the SOXX semiconductor index, alongside unrelated additions like DraftKings, Flutter, Zoetis, and Lululemon 1. The move signals that Burry views AI-linked chipmakers as overextended, even as much of the rest of the market continues to bid up the sector on the strength of ongoing infrastructure spending.

Memory Makers Tell a Different Story

Burry's short thesis arrives just as Samsung is painting a starkly more bullish picture for at least one corner of the chip world: memory. The company's latest results indicate that demand tied to AI infrastructure build-outs is not cooling off, and Samsung expects supply to remain tight through 2028 as cloud providers lock in multi-year purchase agreements 2. That tightness has already rippled through the broader memory market, with stocks like Micron and Sandisk seeing notable gains following Microsoft's latest earnings report, where an analyst praised the company's balance between aggressive AI investment and financial discipline 5. The contrast is notable: Burry is shorting the very company, Micron, that other market participants are treating as a prime beneficiary of a structural memory shortage.

Cracks Beneath the Surface

Not all the sector commentary is unambiguously bullish, however. Some analysts argue that a wave of "good enough" AI technology, spurred in part by recent developments out of China, has begun to rattle confidence in premium chip valuations, raising questions about whether every player in the semiconductor supply chain can command the pricing power investors have assumed 3. This narrative complicates the picture Samsung is telling, suggesting that while raw demand for AI compute and memory remains robust, the competitive and pricing dynamics underlying that demand are shifting in ways that could pressure margins for chipmakers positioned at the higher end of the market.

A Sector in Flux

Beyond the immediate chip debate, broader technology trends are compounding the uncertainty. Coverage of the enterprise tech landscape points to a moment of rapid transformation, encompassing AI agents, foldable devices, rising cyberattack threats, robotics, and a fresh round of major chip deals, all reshaping how businesses plan technology investment 4. Taken together, the divergence between Burry's bearish positioning, Samsung's multi-year supply confidence, Microsoft-driven optimism in memory stocks, and warnings about "good enough" AI competition illustrates just how unsettled sentiment remains around AI chip valuations. Investors are left weighing genuine, sustained infrastructure demand against the risk that expectations, and prices, have run ahead of fundamentals.
