NVIDIA’s Investment in Intel Sparks New Era in US Semiconductor Industry, Key to AI Chip Competition

2025-09-19

Recent news reveals that NVIDIA’s $5 billion investment in Intel triggered Intel’s share price to surge by about 22.8% on September 18, marking its largest single-day gain since 1987 and attracting wide attention in the semiconductor sector. This momentum helped U.S. major indices hit historic highs on the same day, with the S&P 500 rising 0.48%, Nasdaq up 0.94%, and the Philadelphia Semiconductor Index surging 3.6%. Furthermore, the Federal Reserve's recent one-rate-cut decision has fueled expectations for a looser monetary policy supporting economic growth and stock market performance.

Key Data and Market Reactions:

  • Intel's stock soared 22.8% on the day, while NVIDIA's shares rose about 3.5%, reflecting market approval of their partnership.
  • The Philadelphia Semiconductor Index leading tech sector gains with a 3.6% jump, signaling investor optimism toward semiconductor prospects.
  • Memory sector stocks like Winbond, Macronix, and Powerchip gained more than 4%, driven by foreign capital interest.
  • The U.S. government continues to support domestic semiconductor capacity expansion via the CHIPS Act, enhancing industry competitiveness while the Nvidia-Intel joint push into AI and data center chips fosters innovation.
  • Intel’s price-to-earnings ratio has climbed to 57 times, matching the 2001 dot-com bubble peak, reflecting heightened market risk awareness.

NVIDIA’s strategic investment into Intel not only stimulated the latter’s share price in the short term but also presents a renewed opportunity for resource integration and technological advancement in the semiconductor industry. In the near term, benefiting from Fed easing and cooperation themes, semiconductor-related stocks are expected to exhibit higher volatility and active capital flows, suggesting caution over valuation risks. Medium term prospects depend heavily on Intel’s execution of joint R&D plans with NVIDIA, strengthening its positioning in AI and data center chips while leveraging U.S. governmental industrial support. Successful implementation will bolster its leadership in cutting-edge technology and enhance sector competitiveness. However, execution risk and market acceptance remain critical variables, and investors should monitor product rollout schedules and global semiconductor policy shifts closely.
