Alphabet’s stock buybacks: History & investor impact explained

The article reviews Alphabet’s long-running share repurchase program and its implications for investors. Alphabet first launched buybacks in late 2015, authorizing up to $5.099 billion, and repurchased $348 billion in stock from 2015 through 2025. Buybacks accelerated alongside rising profits and free cash flow, peaking near 99% of free cash flow in 2022, then remaining elevated in 2023–2024 before easing in 2025. The key market takeaway is that Alphabet has not repurchased shares in 2026 so far, as it prioritizes heavy AI-related capital spending and continued dividends. Capital expenditures more than doubled in the first half of 2026 versus the prior year, leaving just $4.3 billion in free cash flow for Jan–Jun 2026 versus $24.3 billion a year earlier. Despite the pause, Alphabet still has $69.5 billion authorized for future buybacks, which could support the stock if spending normalizes later.
