U.S. stock futures decline as investors react to higher AI capital expenditure plans from Alphabet and Tesla, coupled with rising oil prices and inflation concerns.

U.S. stock futures fell ahead of Thursday's session as investors digested quarterly results from major technology companies. Concerns over Alphabet's increased 2026 capital expenditure outlook, potentially reaching $205 billion, and Tesla's negative free cash flow due to higher capital spending, weighed on sentiment. These company-specific developments, combined with rising Treasury yields on renewed inflation concerns and surging oil prices, pressured broader market sentiment.
