Key Takeaways
- Citadel’s Ken Griffin elevated Nvidia and Amazon to his top two portfolio positions in Q4 2024, simultaneously exiting his Tesla position
- Nvidia’s autonomous vehicle suite features Omniverse simulation, Cosmos data generation, and Alpamayo reasoning models, with CFO projecting hundreds of billions in robotaxi revenue within ten years
- Amazon’s Zoox leads with the only purpose-designed robotaxis deployed on American public roads, active in Las Vegas and San Francisco, awaiting NHTSA commercial approval
- Amazon shares have declined 14% year-to-date in 2026, yet analysts maintain a Strong Buy consensus with a mean price target of $284.30
- Mistral AI secured approximately 13,800 Nvidia GB300 GPUs for a Paris-area data center, representing an estimated $575 million equipment purchase
Billionaire hedge fund manager Ken Griffin significantly increased his exposure to both Nvidia and Amazon throughout Q4, positioning these technology giants as his fund’s dominant holdings by year-end December. Simultaneously, Griffin completely liquidated his Tesla stake.
These portfolio adjustments arrive as autonomous transportation captures heightened investor focus. American light-duty vehicles accumulate more than 3 trillion annual miles. Even accounting for competitive pricing pressures, the robotaxi sector presents a trillion-dollar addressable market.
Nvidia provides critical hardware and software infrastructure powering numerous self-driving initiatives. The company’s GPUs maintain industry leadership for AI computing tasks, regularly surpassing competitors across training and inference performance metrics.
The chipmaker has assembled a comprehensive robotaxi development platform. Its Omniverse technology creates realistic urban simulations. Cosmos produces synthetic training datasets. Alpamayo represents a suite of reasoning models enabling autonomous systems to interpret and traverse real-world conditions.
Nvidia CFO Colette Kress informed analysts the robotaxi segment possesses potential to deliver hundreds of billions in revenue throughout the coming decade. She emphasized that virtually every significant automaker and mobility provider developing autonomous capabilities incorporates Nvidia technology.
Nvidia’s Broadening Revenue Streams
Beyond autonomous vehicles, Nvidia experiences robust demand throughout AI infrastructure markets. French artificial intelligence firm Mistral AI secured $830 million through debt financing and intends to construct a Paris-region data center equipped with approximately 13,800 Nvidia GB300 GPUs. Industry estimates value this chip procurement at roughly $575 million.
Worldwide cloud infrastructure expenditure reached $110.9 billion during Q4 2025, representing 29% year-over-year expansion. Analyst firm Omdia anticipates 27% growth continuing through 2026.
Nvidia unveiled its Space-1 Vera Rubin computing module on March 16, engineered specifically for orbital data centers. Emerging startup Starcloud attracted $170 million funding at a $1.1 billion valuation and plans launching a satellite-based GPU cluster before year-end.
Wall Street projects Nvidia’s earnings advancing at a 38% compound annual rate across the next three years. Shares currently command approximately 35 times forward earnings with market capitalization exceeding $4 trillion.
Amazon’s Dual Strategy in Robotaxis and Cloud Computing
Amazon operates Zoox, presently the exclusive autonomous driving enterprise deploying purpose-engineered robotaxis on American public streets. Zoox vehicles provide service in Las Vegas and San Francisco, with Austin testing ongoing and Miami expansion scheduled for later this year.
Zoox recently submitted applications to the NHTSA requesting authorization to operate commercial ride-hailing services utilizing up to 2,500 robotaxis. Regulatory approval decisions are anticipated in early April.
Morgan Stanley forecasts Zoox capturing 12% of autonomous ride-sharing volume annually by 2032.
Amazon shares have retreated approximately 14% during 2026, currently trading near $199. Investor concerns center on $200 billion planned AI infrastructure investments for the year alongside AWS growth deceleration relative to cloud competitors.
Jefferies analyst Brent Thill upholds a Buy rating with a $300 price objective, characterizing the sell-off as excessive. The aggregate Wall Street consensus remains Strong Buy, reflecting an average analyst price target of $284.30 across 44 coverage firms.
Amazon’s forthcoming earnings announcement represents the next significant catalyst for share price movement.
