Stock Market Today: Intel Surges on Nvidia Stake and Chip Partnership

Intel Corp (NASDAQ: INTC) skyrocketed 22.8% today to close at $30.57, driven by a major investment and partnership announcement. Trading volume topped 520 million shares, more than five times its three-month average of about 97 million on the news. The stock also reached its 52-week high of $32.38 intraday.

The broader market also advanced. The S&P 500 (SNPINDEX: ^GSPC) rose 0.48% to 6,631.96, and the Nasdaq Composite (NASDAQINDEX: ^IXIC) gained 0.94% to 22,470.72.

Among peers, NVIDIA Corp (NASDAQ: NVDA) closed at $176.24, up 3.49% on the day and likely lifted by news of its $5 billion stake in Intel. Advanced Micro Devices Inc (NASDAQ: AMD) finished at $157.92, down 0.78%.

The jump followed Nvidia's declaration that it will invest in Intel and collaborate on custom PC and data center chips. The deal combines Nvidia's GPU strength with Intel's CPU base, aiming to boost U.S. semiconductor capacity and meet accelerating AI demand.

While the partnership marks one of Intel's biggest positive developments in years, challenges remain. Execution, regulatory approvals, and Intel's ability to regain ground in AI and foundry will determine how much long-term value this move delivers.
