TLDR
- Billionaire hedge fund manager Ken Griffin made Nvidia and Amazon his two largest holdings in Q4 2024, while selling Tesla
- Nvidia’s robotaxi tools include Omniverse, Cosmos, and Alpamayo, and its CFO says the segment could generate hundreds of billions in revenue over the next decade
- Amazon’s Zoox is the only company with purpose-built robotaxis on U.S. streets, operating in Las Vegas and San Francisco, with an NHTSA commercial application pending
- Amazon stock is down 14% in 2026, but Wall Street’s consensus is Strong Buy with an average price target of $284.30
- Mistral AI ordered roughly 13,800 Nvidia GB300 GPUs for a new Paris data center, in a deal estimated at around $575 million
Hedge fund billionaire Ken Griffin added to his positions in Nvidia and Amazon during the fourth quarter, making them the two largest holdings in his fund as of December. At the same time, he sold his stake in Tesla.
The moves come as the autonomous vehicle market draws serious investor attention. Light-duty vehicles in the U.S. travel over 3 trillion miles per year. Even at reduced prices, robotaxis represent a trillion-dollar market opportunity.
Nvidia supplies the hardware and software that many autonomous driving companies rely on. Its GPUs are the industry standard for AI workloads, consistently outperforming rivals in benchmarks for both training and inference.
The company has built a full robotaxi development toolkit. Omniverse simulates city environments. Cosmos generates synthetic training data. Alpamayo is a family of reasoning models that help autonomous vehicles perceive and navigate the real world.
Nvidia CFO Colette Kress told analysts that robotaxis could generate hundreds of billions of dollars in revenue over the next decade. She added that every major automaker and service provider working on autonomous vehicles is using Nvidia technology in some form.
Nvidia’s Expanding Market
Beyond robotaxis, Nvidia is seeing strong demand across AI infrastructure. French AI company Mistral AI raised $830 million in debt financing and plans to build a data center near Paris housing around 13,800 of Nvidia’s GB300 GPUs. That order is estimated to be worth roughly $575 million in chip sales.
Global cloud infrastructure spending hit $110.9 billion in Q4 2025, up 29% year-over-year. Research firm Omdia forecasts 27% growth in 2026.
Nvidia also announced the Space-1 Vera Rubin computing module on March 16, designed for space-based data centers. Startup Starcloud raised $170 million at a $1.1 billion valuation and is planning a satellite GPU cluster launching later this year.
Wall Street expects Nvidia’s earnings to grow at 38% annually over the next three years. The stock currently trades at about 35 times earnings and carries a market cap above $4 trillion.
Amazon’s Robotaxi and Cloud Bets
Amazon owns Zoox, currently the only autonomous driving company with purpose-built robotaxis on U.S. public roads. Zoox vehicles operate in Las Vegas and San Francisco, with testing underway in Austin and Miami launches planned for later this year.
Zoox recently applied to the NHTSA to run a commercial ride-sharing service with up to 2,500 robotaxis. The agency is expected to decide in early April.
Morgan Stanley projects Zoox will handle 12% of autonomous rides annually by 2032.
Amazon stock has dropped around 14% in 2026, trading near $199. Concerns include $200 billion in planned AI capital spending for the year and slowing AWS growth compared to rivals.
Jefferies analyst Brent Thill maintains a Buy rating with a $300 price target, calling the selloff an overreaction. The broader Wall Street consensus is Strong Buy, with an average price target of $284.30 from 44 analysts.
Amazon’s next earnings report is the upcoming major catalyst for the stock.
