Woofun AI reports that US stock futures declined across the board on Friday, with Nasdaq 100 futures dropping 1.2%, S&P 500 futures falling 0.5%, and Dow Jones futures losing 67 points (-0.1%). The sell-off was led by the technology sector, where the XLK ETF fell 1.6%, extending previous losses. Chip stocks faced significant pressure following reports that OpenAI is considering postponing its IPO until next year due to market volatility and unstable sentiment. JPMorgan's trading desk noted this reinforces concerns about AI infrastructure investment sustainability, while analyst Adam Crisafulli stated the delay could slow AI spending expansion. In the semiconductor space, ON Semiconductor fell over 13% after acquiring Synaptics, while Micron Technology and SanDisk both declined by more than 5%.
