Nvidia has announced an unprecedented $5 billion investment in Intel, signaling a strategic pivot in the global chip industry and marking a lifeline for the once-dominant but recently embattled U.S. chipmaker.

This move comes soon after a whirlwind of corporate and political drama involving Intel, America’s one-time semiconductor chips champion, that saw President Trump call for the resignation of CEO Lip-Bu Tan, his sudden reversal, and then the U.S. government itself making an unprecedented investment into Intel, taking a nearly 10% stake in the process.

Nvidia, the world’s leader in artificial intelligence chips, announced it will invest $5 billion in Intel’s common stock at a discounted price of $23.28 per share. The news prompted a premarket surge in Intel shares of a whopping 30%. Nvidia CEO Jensen Huang hailed the deal as a “historic collaboration” that will tightly couple Nvidia’s AI and accelerated computing stack with Intel’s central processing units (CPUs) and its x86 ecosystem. Specifically, Intel will build and bring to market x86 system-on-chips (SOCs) that integrate NVIDIA RTX GPU chiplets.

“AI is powering a new industrial revolution and reinventing every layer of the computing stack — from silicon to systems to software. At the heart of this reinvention is NVIDIA’s CUDA architecture,” Huang said in the press release on the announcement. Together, he added, the companies will expand their ecosystems and “lay the foundation for the next era of computing.”
