Microsoft stock rises after OpenAI’s ChatGPT ad test plan, as Europe probes loom
Microsoft shares rose 0.9% to $460.77 Friday after OpenAI, which Microsoft backs, announced plans to test ads in ChatGPT for some U.S. users. Swiss and Italian regulators opened new probes into Microsoft’s licensing and gaming businesses. The S&P 500 and Nasdaq ended little changed. Microsoft’s earnings are due later this month.
