Futures climbed on Wednesday as the latest batch of earnings pointed to strong demand for, and spending on, artificial intelligence. SpaceX reported higher-than-expected AI-related outlays, which overshadowed results that broadly beat forecasts. The company's increased investment in AI infrastructure signals growing confidence in the sector's trajectory.

Meanwhile, Nvidia Corp. rallied after Elon Musk touted his computing plans, reinforcing the narrative that major tech players are doubling down on AI capabilities. Nvidia's stock gains reflected investor optimism about sustained AI spending across the industry.

As the S&P 500 approaches another record, the focus remains squarely on artificial intelligence as the primary growth driver. The convergence of corporate spending and executive enthusiasm suggests the AI boom is far from over, with implications extending across multiple sectors and asset classes. Analysts noted that the combination of private sector investment and public statements from influential figures contributed to a supportive environment for tech stocks.
