Yahoo Finance analyzed on August 4th that tech giants such as Microsoft, Google, Amazon, and Meta have invested approximately $1 trillion in AI data centers. Specifically, Microsoft is projected to spend $115.95 billion on property and equipment by the end of fiscal year 2026; Google spent $44.92 billion in a single quarter, resulting in a negative free cash flow of $5.86 billion and a suspension of share buybacks; Amazon spent $54.21 billion in the June quarter; and Meta expects full-year capital expenditures to be between $130 billion and $145 billion. These massive capital expenditures will gradually be reflected in income statements through depreciation expenses over the next few years, putting pressure on profit margins. Meta has already shown early warning signs, with its operating profit margin falling from 43% a year ago to 31%, and free cash flow dropping from $8.55 billion to $784 million. To mitigate depreciation pressure, Microsoft announced on July 29th that it would extend the estimated useful life of its data centers and office buildings from 15 years to 25 years, starting in fiscal year 2027.
