[Analysis: OpenAI Delays IPO, Triggering Sell-Off, U.S. Tech Stocks Decline Across the Board] According to CNBC, futures for the three major U.S. stock indices collectively fell on Friday, with the tech sector leading the market downturn. Chip and storage-related stocks generally weakened. Two core market concerns continue to intensify: first, the rising cost pressures of AI infrastructure; second, expectations of a slowdown in overall financing pace within the AI sector. Media reports indicate that OpenAI is considering postponing its IPO to next year. Reasons for the delay include increased volatility in AI-related stocks, weakening market sentiment, and the underwhelming stock performance of SpaceX following its listing, prompting investment banks and companies to reassess the current IPO window.
