Key Takeaways
- Citadel founder Ken Griffin significantly increased his Nvidia and Amazon positions in Q4 2024, establishing them as his fund’s top two investments while exiting Tesla entirely
- Nvidia’s autonomous vehicle technology suite features Omniverse for simulation, Cosmos for data generation, and Alpamayo reasoning models, with executives forecasting hundreds of billions in revenue potential this decade
- Amazon subsidiary Zoox operates the nation’s only purpose-built autonomous taxis currently serving passengers in Las Vegas and San Francisco, with federal commercial licensing under review
- Amazon shares have declined 14% year-to-date in 2026, yet analysts maintain a Strong Buy consensus with a $284.30 average target price
- French AI firm Mistral AI placed an order for approximately 13,800 Nvidia GB300 GPUs worth an estimated $575 million for their Paris facility
Billionaire hedge fund manager Ken Griffin substantially expanded his positions in both Nvidia and Amazon throughout the final quarter of 2024, elevating these tech giants to the top two slots in Citadel’s investment portfolio. Simultaneously, Griffin completely divested his Tesla holdings.
This strategic repositioning reflects growing institutional interest in the autonomous transportation sector. American light-duty vehicles collectively log more than 3 trillion miles annually. Even with competitive pricing pressure, the robotaxi industry presents a market opportunity measured in trillions of dollars.
Nvidia provides both the computing hardware and development platforms that power many autonomous driving initiatives. The company’s graphics processing units have become the default choice for artificial intelligence applications, regularly surpassing competitors in performance tests for model training and real-time inference tasks.
The chipmaker has assembled a comprehensive suite of tools for robotaxi development. Its Omniverse platform creates detailed virtual urban environments. Cosmos generates artificial training datasets. The Alpamayo model family provides reasoning capabilities that enable self-driving systems to interpret and respond to real-world conditions.
Nvidia Chief Financial Officer Colette Kress informed investors that the autonomous vehicle sector could contribute hundreds of billions in revenue throughout the coming decade. She noted that virtually every major automotive manufacturer and mobility service company developing self-driving technology incorporates Nvidia solutions into their systems.
Broader AI Infrastructure Momentum for Nvidia
Beyond autonomous vehicles, Nvidia continues experiencing robust demand throughout the AI infrastructure landscape. French artificial intelligence company Mistral AI secured $830 million in debt capital and announced plans for a Paris-area data center that will deploy approximately 13,800 Nvidia GB300 graphics processors. This procurement represents roughly $575 million in chip revenue for Nvidia.
Worldwide cloud infrastructure investment reached $110.9 billion during Q4 2025, marking a 29% increase from the previous year. Industry analyst firm Omdia projects 27% expansion for 2026.
On March 16, Nvidia unveiled the Space-1 Vera Rubin computing platform, engineered specifically for orbital data centers. Space technology startup Starcloud recently closed a $170 million funding round at a $1.1 billion valuation and intends to deploy a satellite-based GPU network before year-end.
Financial analysts anticipate Nvidia’s profits will expand at a 38% compound annual rate through the next three years. The stock currently carries a price-to-earnings multiple near 35 times and commands a valuation exceeding $4 trillion.
Amazon’s Dual Strategy in Robotaxis and Cloud Computing
Amazon operates Zoox, presently the sole autonomous mobility provider running custom-designed robotaxis on American public streets. Zoox vehicles transport passengers in Las Vegas and San Francisco, with trials proceeding in Austin and Miami deployments scheduled for later in 2026.
Zoox submitted a request to the National Highway Traffic Safety Administration for authorization to operate a commercial ride-hailing fleet with up to 2,500 autonomous vehicles. Federal regulators are anticipated to issue their determination in early April.
Morgan Stanley forecasts that Zoox will capture 12% of all autonomous ride-sharing trips by 2032.
Amazon’s stock price has fallen approximately 14% in 2026, currently trading around $199 per share. Investor apprehension centers on the company’s announced $200 billion artificial intelligence infrastructure investment plan for the year alongside AWS revenue growth trailing cloud competitors.
Jefferies analyst Brent Thill upholds a Buy recommendation with a $300 price objective, characterizing the recent decline as an excessive market response. The consensus among Wall Street analysts remains Strong Buy, with 44 analysts establishing an average target of $284.30.
Amazon’s forthcoming quarterly earnings announcement represents the next significant catalyst for share price movement.
