Microsoft held its 2026 AI spending plan roughly steady while Google, Amazon and Meta all raised theirs, and Wall Street rewarded the restraint. Microsoft shares jumped 15% by Thursday's close, the company's best trading day in almost two decades, after CFO Amy Hood walked analysts through the conservative capex plan.
Microsoft shares jumped 15% by the close of trading Thursday. It was the company's best day on the market in almost two decades. The move added the most market value in one day by any US company in history.
The reaction is notable because Microsoft didn't ramp up spending — it held back. Its 2026 capital spending plan stayed unchanged, and the figure actually fell from $190 billion to $175 billion due to an accounting tweak.
Rivals keep raising their budgets
Google, Amazon and Meta moved the opposite way this earnings season. Google added another $15 billion to its 2026 forecast. Amazon separately increased its 2026 spending by $20 billion, and Meta boosted its own plans as well. Against that backdrop, Microsoft's choice to hold spending flat stands out.
Rising memory costs sharpen the contrast
The gap looks even wider once memory chip costs enter the picture. Memory chip prices have soared, which has pushed capex even higher, and Microsoft isn't immune to that pressure. If memory costs keep rising while the overall budget stays flat, less money is left for actually building AI data centers — which is arguably more cautious than the flat headline number first suggests.
Investors reward the conservative signal
Investors cheered the restraint. Shares surged immediately when CFO Amy Hood outlined the conservative spending plan on a call with analysts. Strong Azure growth and rising Copilot adoption helped too, but investors were mostly encouraged by signs that the company is weighing returns, not just piling on spending.
