Google Gemini 3 launch wipes $250 billion off Nvidia market value

Google’s Gemini 3 rollout on Nov 18 erased about $250 billion from Nvidia’s market capitalization in a single morning of trading [1]. The new model, embedded directly into Google Search, topped the LMArena leaderboard and posted record scores on benchmarks such as Humanity’s Last Exam (41 %) and GPQA Diamond (93.8 %) [1].

The reaction reverberated across the AI‑focused equity landscape. Nvidia fell nearly 4 % since the Gemini 3 announcement and is down roughly 9 % over the past month, while Alphabet rose 11 % in five days and almost 19 % in a month [1]. Rival chipmakers felt the shock too: AMD slipped over 13 % in five days and more than 23 % over a month, and Oracle dropped 10 % and 30 % respectively [1].

Analysts see the week as a crossroads for the AI trade. Google’s I/O conference (May 19‑20) will showcase how the company plans to turn Gemini into an operating‑system‑like layer across Android, Search, Chrome and cloud services, with 67 buy ratings and a 12‑month price target 8 % above the latest close [2]. The following day, Nvidia’s fiscal Q1 results are due, where investors will scrutinize demand for its Blackwell and Rubin chips, margin trends and any revision to its $1 trillion data‑center revenue outlook [2][3]. Consensus expects $78.8 billion in revenue and $1.75 EPS, but a miss or muted guidance could dampen the broader AI rally [3].

The juxtaposition of Google’s aggressive AI integration and Nvidia’s earnings spotlight underscores a shifting power balance. If Google’s Gemini 3 proves a durable competitive edge, it could accelerate a move away from Nvidia‑centric AI infrastructure toward a more diversified ecosystem. Conversely, a strong Nvidia report could reaffirm the chipmaker’s dominance and keep the AI trade buoyant.

The market now watches whether Google’s AI push will rewrite the hierarchy or simply add another contender to a still‑evolving AI landscape.
