The largest U.S. technology companies reported record cash generation during the first nine months of 2026 but returned the lowest proportion of that cash to shareholders in at least 15 years, according to a recent analysis. This shift reflects increased spending on artificial intelligence (AI) initiatives, which is constraining share buybacks, a long-standing mechanism supporting tech stock prices.

Data from Microsoft, Alphabet, Amazon, Meta, and Oracle indicate these firms allocated just 9.3 percent of their operating cash flow to dividends and stock repurchases in the first three quarters of the year, a sharp decline from 27.4 percent during the same period in 2025. Operating cash flow across the group surged 29 percent to a record $542.9 billion, but capital expenditures, largely driven by AI investments, doubled to $556.9 billion. This marks the first time since 2011 that spending outpaced cash generation for these companies, resulting in a combined free cash-flow deficit of $14 billion compared to a $143.5 billion surplus a year earlier.

The reduction in share buybacks has been particularly pronounced. The five companies cut repurchases by 83 percent to $13.6 billion, down from $81.8 billion in the first nine months of 2025. In contrast, dividends slightly increased to $37 billion from $33.9 billion in the previous year. Notably, Alphabet and Meta refrained from repurchasing shares in 2026 after spending $66.5 billion on buybacks in 2025. Amazon, which does not pay dividends, has not conducted share repurchases since 2022.

Microsoft accounted for the majority of remaining repurchasing activity, although it reduced buybacks to $4.4 billion in the third quarter from $5.7 billion in the same period last year. These spending patterns underscore a growing reliance on AI investments to generate future profit growth, as traditional shareholder returns via buybacks decline.

Industry analysts note that the shift in capital allocation introduces uncertainty for investors accustomed to steady buyback programs as a support for stock prices. With less cash being returned directly to shareholders, the companies’ ability to deliver strong earnings growth from AI projects will be critical to maintaining market confidence.
