Intel stock (NASDAQ: INTC) surged 23% on Thursday, September 18, 2025, after a major announcement. Nvidia revealed a $5 billion investment in Intel and a partnership to co-develop new data center and PC products. This collaboration is intended to accelerate workloads and applications across hyperscale, enterprise, and consumer markets.

According to S&P Global Market Intelligence data, Intel's foundry business did only $17.5 billion in revenue last year, and foundry revenue has been falling for the last two years. The foundry unit also lost $8 billion in 2024 -- meaning for every $1 worth of chips Intel makes on contract for a customer, the company loses about $0.46.

Intel’s stock jumped more than 20% Thursday after it announced a $5 billion investment from Nvidia, along with plans to cooperate on new technology for data centers and PCs.
