Three years of ChatGPT: Nvidia up 10x, the Mag Seven tripled, and AI discourse has finally reached the Thanksgiving table
Dec 1, 2025
Key Points
- Nvidia has surged to a $4.4 trillion valuation in three years, up 10x from $420 billion, as retail and institutional investors funneled AI capital into the company due to its liquid stock and lack of alternative infrastructure plays.
- The Magnificent Seven's composition has completely reordered by market cap in three years, with Nvidia now topping the ranking ahead of Apple, which held the largest cap in November 2022.
- Google's Gemini app is eroding OpenAI's consumer dominance, with Gemini downloads catching ChatGPT and users spending more time in the app, despite Nvidia's continued infrastructure monopoly.
Summary
Three years after ChatGPT's launch, the Magnificent Seven has tripled in value from under $8 trillion to over $21 trillion. Nvidia has outpaced them all, rising 10x from $420 billion to $4.4 trillion. That move has created an industrial complex of retail and institutional investors who heard AI was big, couldn't buy OpenAI, and landed on Nvidia as the logical next step. The stock's liquidity meant anyone could deploy serious capital without SPV gatekeeping or illiquidity friction. Runway's Sikhi Chen and investor Nir Zuk both put uncomfortable amounts of net worth into Nvidia years ago. One fund is explicitly branded around buying only Nvidia.
Market concentration has shifted dramatically. Apple held the largest market cap in November 2022 with a sizable lead over Microsoft, Amazon, and Google. That gap has compressed as hyperscalers grew on the back of the AI boom. Today's ranking by market cap is Tesla, Meta, Amazon, Microsoft, Alphabet, Apple, then Nvidia at the top—a complete reordering in three years.
Whether Nvidia is truly a monopoly or whether alternative suppliers can break its dominance remains unresolved. Broadcom sits at number 10 globally but faces a structural branding problem: it has no consumer angle whatsoever. The Mag Seven itself tends to include companies with at least some consumer accessibility. Tesla, Meta, Amazon, Microsoft, and Google all have consumer products or brands. Nvidia has gaming graphics cards. Broadcom has none. The Mag Seven also appears to be implicitly limited to American companies; including foreign firms would collapse the ranking into a meaningless exercise.
On the consumer side, Google's Gemini app downloads are catching up to ChatGPT. Gemini users now spend more time in the app than ChatGPT users do. OpenAI's first-mover advantage in consumer mindshare is eroding despite Nvidia's continued dominance in infrastructure.
