Interpretation of Tower Semiconductor's Sharp Decline on October 8

Keywords: OpenAI revenue downward revision, AI infrastructure concerns, pullback from high levels

1. On September 30, 2026, OpenAI disclosed to investors that its annualized revenue was close to $50 billion, lower than the previously rumored $70 billion. Combined with the intraday weakness of Nasdaq and S&P 500 indexes on October 9, 2026, this has weakened expectations for AI infrastructure demand, putting pressure on the valuation of the silicon photonics business. 2. On October 9, 2026, Oracle revealed that its New Mexico data center is facing pipeline delays and is considering trucking natural gas to resolve power supply issues, highlighting how data center power bottlenecks constrain AI expansion and the related supply chain. 3. As of October 9, 2026, the company’s cumulative increase since the beginning of the year is 96.58%, but it has fallen by 4.34% in the past five days, facing profit-taking pressure as the AI and optical communications sectors weaken.
