Burry Doubles Down on AI Shorts as Nebius, Nvidia, Micron Defy Bear Trap: Short Seller Tracker

Michael Burry is finding out that betting against a momentum-fueled artificial intelligence trade is easier said than done.

The investor made famous by The Big Short movie about his bet against the housing bubble in 2008, has widened his bearish campaign against the sector, adding to short positions in high-flyers like $NEBIUS (NBIS.US)$, $Micron Technology (MU.US)$, and $Oracle (ORCL.US)$, alongside a broader wager against the $iShares Semiconductor ETF (SOXX.US)$.

Labeling $NVIDIA (NVDA.US)$’s financing architecture a "$500 billion Wall Street stunt" backed by private-credit structures, Burry argued that the latest surge across infrastructure names represents textbook peak-boom behavior.

Yet, Wall Street is paying him little heed. Rather than buckling under the weight of Burry’s warnings and elevated short interest—including a tripling in Nebius short volume past 10 million shares—the market's appetite has held firm. Nebius, Nvidia, Micron, and Oracle are all trading higher, brushing off the high-profile skepticism.

Burry’s latest flurry of short additions came hot on the heels of Nebius’s blowout second-quarter earnings report, which sent revenue up more than fivefold to $582.3 million and pushed the stock past $250.

Unmoved by the stellar numbers—or the company's raised five-gigawatt capacity guidance—Burry added to his Nebius short at $247, pointing to aggressive financing models, residual-value guarantees, and systemic risks mirroring past corporate scandals.

Despite short volumes scaling up and technical indicators flashing overbought signals, incoming capital has overpowered bearish pressure, allowing core infrastructure plays to continue commanding aggressive buying support.

Nebius shares gained another 3.5% to $268.14, raising the risk of a squeeze on short sellers including Burry. Micron, which has been a target of Burry’s bearish wagers, rose 2.4%, adding to its 23% rebound from a low in late July. Nvidia, which he has criticized for the circular financing, is up Thursday, taking gains from a recent low to more than 19%. Meanwhile, Oracle has surged 37% from a low in July.

While Burry’s prominent bearish footprint ensures that sector volatility will remain elevated, the immediate tape tells a clear story that bulls are still firmly in control and treating high-profile warnings as mere noise in an otherwise relentless AI rally.
