Michael Burry Shorts Oracle and Nebius Amid AI Sector Overvaluation Concerns

Key Facts

Amid escalating concerns over tech sector valuations, renowned investor Michael Burry has announced short positions against Oracle and Nebius Group N.V. According to reports, Burry characterized many AI-linked companies as appearing bloated and vulnerable to a market downturn. This move by the 'Big Short' investor signals a potential bubble or significant correction ahead for these specific stocks within the artificial intelligence ecosystem.

This bearish bet comes as AI cloud infrastructure stocks face heightened volatility, with Oracle (ORCL) closing at $143.47 and Nebius (NBIS) at $189.88 as of August 6, 2026. Per market data, Nebius experienced significant price swings during the August 6 session, hitting a high of $215.51 before retreating toward its daily low of $189.17, underscoring the instability Burry highlighted in his sector assessment.

Traders should watch for price action around key levels, as Oracle closed August 6, 2026, near its daily low of $138.72. While the upcoming economic calendar shows no direct catalysts for these firms in the next seven days, broader market sentiment remains sensitive to institutional moves and recent manufacturing data, such as the US ISM Manufacturing PMI which recently posted a reading of 55.6.
