Tower Semiconductor's stock fell 7.4% after a report that OpenAI may postpone its IPO into 2027, citing concerns the company's growth may be slower than hoped. This matters because investors fear reduced infrastructure spending by OpenAI and its competitors could hurt AI semiconductor suppliers; Tower has surged 465% in the past year on demand for its silicon photonics chips from data centers.

Tower Semiconductor shares dropped 7.4% on Friday following a report that OpenAI may delay its initial public offering from this year into 2027. The New York Times cited OpenAI's hesitation partly due to Space Exploration Technologies' recent IPO performance.
Why it matters
Investors worry that if OpenAI's growth and financials are weaker than expected—the Wall Street Journal reported it is considering price cuts to compete with rival Anthropic—the company may reduce infrastructure spending. Since AI semiconductor stocks have risen significantly this year, even rumors of slower investment can trigger sell-offs in related companies like Tower.
What to watch
Tower stock is up 465% over the past year due to demand for its silicon photonics technology from AI data centers switching away from copper networking. However, the article notes that even if OpenAI struggles, other large cloud providers may continue infrastructure investment, and the broader AI build-out could still benefit semiconductor makers.
