Key Takeaways
- Ken Griffin’s Citadel positioned Nvidia and Amazon as top portfolio holdings in Q4 2024, divesting from Tesla completely
- Nvidia’s autonomous vehicle platform features Omniverse simulation, Cosmos data generation, and Alpamayo reasoning models, with potential for hundreds of billions in revenue
- Amazon subsidiary Zoox operates the only purpose-built autonomous taxis on American public roads, with services in Las Vegas and San Francisco
- Amazon shares have declined 14% 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, valued at approximately $575 million
During the final quarter of 2024, hedge fund titan Ken Griffin significantly expanded his investments in both Nvidia and Amazon, elevating them to become Citadel’s largest equity positions by year-end. Simultaneously, the billionaire investor completely exited his Tesla holdings.
These portfolio adjustments arrive amid intensifying competition in the self-driving vehicle sector. With light-duty vehicles logging more than 3 trillion miles annually across the United States, the autonomous taxi market presents a revenue opportunity measured in the trillions, even accounting for competitive pricing pressures.
Nvidia provides the essential computing hardware and software infrastructure that powers many autonomous driving platforms. The company’s GPUs remain the gold standard for artificial intelligence computing tasks, regularly surpassing competitors in performance tests for both model training and real-time inference operations.
The chipmaker has assembled a comprehensive development ecosystem for autonomous vehicles. Omniverse creates detailed simulations of urban environments. Cosmos produces synthetic datasets for model training. Alpamayo represents a suite of advanced reasoning models enabling self-driving systems to interpret and respond to real-world conditions.
Nvidia Chief Financial Officer Colette Kress informed investors that the autonomous taxi segment could deliver revenue in the hundreds of billions throughout the coming decade. She emphasized that virtually every significant automotive manufacturer and mobility service provider developing self-driving technology relies on Nvidia’s platform in some capacity.
Expanding Horizons for Nvidia
Aside from autonomous vehicles, Nvidia continues experiencing robust demand throughout the AI infrastructure landscape. Mistral AI, a French artificial intelligence company, secured $830 million in debt capital and announced plans for a Parisian data center deployment featuring roughly 13,800 GB300 GPUs from Nvidia. Industry estimates place this chip procurement at approximately $575 million.
Worldwide cloud infrastructure expenditure reached $110.9 billion during Q4 2025, representing 29% year-over-year expansion. Research organization Omdia anticipates 27% growth continuing through 2026.
On March 16, Nvidia unveiled the Space-1 Vera Rubin computing module, engineered specifically for orbital data center applications. Space technology startup Starcloud recently closed a $170 million funding round at a $1.1 billion valuation and plans to deploy a satellite-based GPU cluster before year-end.
Financial analysts project Nvidia’s earnings will compound at 38% annually over the next three-year period. The stock currently commands a valuation of approximately 35 times forward earnings, with total market capitalization exceeding $4 trillion.
Amazon’s Dual Strategy in Robotaxis and Cloud Computing
Amazon operates Zoox, presently the sole autonomous vehicle company deploying purpose-designed robotaxis on American public thoroughfares. Zoox vehicles currently provide service in Las Vegas and San Francisco, with testing programs active in Austin and Miami deployments scheduled for later this year.
Zoox submitted a recent application to the National Highway Traffic Safety Administration seeking authorization for commercial ride-hailing operations utilizing up to 2,500 autonomous vehicles. Federal regulators are anticipated to render their decision in early April.
Morgan Stanley research suggests Zoox will capture 12% of all autonomous ride-sharing trips by 2032.
Amazon’s stock price has retreated approximately 14% during 2026, currently trading around $199 per share. Investor concerns center on the company’s announced $200 billion AI infrastructure capital expenditure plan for the year and AWS growth rates trailing behind cloud computing competitors.
Jefferies analyst Brent Thill upholds a Buy recommendation with a $300 price objective, characterizing the recent selloff as an excessive market reaction. The broader analyst community maintains a Strong Buy consensus, with 44 analysts establishing an average target price of $284.30.
Amazon’s forthcoming quarterly earnings announcement represents the next significant catalyst for share price movement.
