Mostly True
Wall Street notched another all-time high as investor optimism over artificial intelligence and corporate earnings lifted the S&P 500 index past the 7,800 mark, extending a rally driven by enthusiasm for AI-related stocks.
The latest record close came amid continued expectations that investment in AI infrastructure and related technologies will translate into sustained corporate profit growth. The S&P 500's move above 7,800 caps a streak of gains that has repeatedly pushed major US indexes into record territory.
The core facts of the claim — that New York markets reached a new all-time high on AI and earnings expectations, and that the S&P 500 crossed the 7,800 level — are supported by the underlying reporting. Details such as the precise closing values, the exact drivers of individual sessions, and how long the rally will continue remain subject to market movement and were not pinned down in the available material.
Given that the central claim aligns with the reported market data while some finer details remain open to interpretation, the claim is assessed as Mostly True.
