Nvidia just crossed the $4.5 trillion market cap threshold Tuesday, driven by a surge in AI infrastructure deals that's reshaping the entire tech landscape. The chipmaker's stock climbed nearly 3% to hit fresh records as investors bet big on the company's dominance in artificial intelligence hardware, with shares now up 39% for 2025.
Nvidia isn't just riding the AI wave anymore - it's basically become the ocean itself. Tuesday's market surge pushed the chipmaker past the $4.5 trillion valuation milestone, cementing its position as the undisputed king of artificial intelligence infrastructure.
The numbers tell a compelling story. Nvidia's stock jumped nearly 3% to hit fresh records, with the company now sitting on 39% gains for 2025. That performance puts it ahead of almost every other megacap stock, trailing only Broadcom which managed 40% gains thanks to its own AI tailwinds.
But here's what's really driving the frenzy: OpenAI essentially handed Nvidia the keys to the AI kingdom last week. The ChatGPT maker announced that Nvidia would take an equity stake worth up to $100 billion in the startup, while simultaneously committing to build hundreds of billions of dollars worth of data centers packed with Nvidia's graphics processing units.
The scale is staggering. OpenAI's "Stargate" project with Oracle will cost $500 billion and span five massive data centers filled with hundreds of thousands of GPUs. According to CEO Jensen Huang, Nvidia's products make up roughly 70% of spending on any new AI data center - meaning the company stands to capture the lion's share of this infrastructure buildout.
"We believe OpenAI came to Nvidia asking for help as Nvidia has a very compelling product, and as the number of users and compute being consumed per user basis is growing," Citi analyst Atif Malik wrote in a research note that raised the firm's price target from $200 to $210.
The OpenAI deal isn't happening in isolation. Meta, Google, and other tech giants are dramatically ramping up their infrastructure spending as AI applications demand ever-more computational power. CoreWeave, a cloud provider where Nvidia holds a significant stake, announced Tuesday it secured a $14.2 billion contract to supply Meta with AI infrastructure services.
