When your customers collectively announce plans to spend $650 billion on AI infrastructure, your stock tends to notice. That is more or less what happened to Nvidia in early 2026, and the ripple effects have been shaping market sentiment ever since.
Nvidia shares posted a gain of roughly 7.7% to 8.2% in February 2026, a move that added more than $300 billion in market value in a matter of days. The catalyst was a cascade of capital expenditure announcements from the biggest names in tech, each one essentially serving as a public endorsement of Nvidia’s hardware as the engine of the AI economy.
Why everyone is suddenly spending so much
Amazon anchored the spending wave with plans for approximately $200 billion in capital investment. The broader tally across major technology firms reached roughly $650 billion in planned AI-related spending for 2026.
Microsoft added more confirmation in July 2026, reporting quarterly capital expenditure of $41 billion, a figure that exceeded analyst expectations. Nvidia shares gained nearly 3% on that news alone.
