Nvidia’s Rise to $4.5 Trillion
Nvidia leads the world with a staggering valuation of $4.53 trillion, surpassing both Apple ($3.9 trillion) and Microsoft ($3.89 trillion).
Nvidia GPUs remain the backbone of AI model training, with customers like OpenAI committing billions of dollars to buy its chips.
Nvidia has also committed to investing $100 billion in OpenAI to build more data centers, raising concerns about the circular nature of recent deals between major AI players.
OpenAI is currently the world’s most valuable private tech company, valued at $500 billion.
AI is Everywhere
The AI craze is creating many more winners than just Nvidia.
For example, in early October, AMD and OpenAI announced a strategic partnership to deploy 6 gigawatts of AMD GPUs. A week later, OpenAI followed up with a strategic collaboration with Broadcom to deploy 10 gigawatts of custom AI chips.
Broadcom shares are up 56% year to date, while AMD has rocketed 115% (its shares climbed 43% the week of the OpenAI announcement).
Fact: The average annual return of the S&P 500 is about 10%.
On the software side, Palantir has quickly risen to become the world’s 45th most valuable company, setting record-breaking P/E and P/S ratios along the way. The firms develops AI platforms that digest vast amounts of data to make predictive insights.
Palantir has been the best-performing S&P 500 stock since its addition to the index in September 2024, and has climbed 1,956% since its October 2020 IPO.
