S&P 500 Slides as AI Shift and Middle East Tensions Fuel Volatility

Software sector outlooks soured following the emergence of OpenAI’s GPT-6 Astra.

Tensions spiked following attacks on Saudi energy infrastructure by Iran-backed groups, driving oil prices higher and complicating the outlook for global inflation and central bank policy.
