Big Tech's Four Giants Spend Nearly $500 Billion in Capex Over First Three Quarters, Shareholder Returns Shrink Significantly
nashnova research
Microsoft, Alphabet, Amazon and Meta spent a combined $496.7 billion on property and equipment in the first three quarters of 2026, nearly doubling year-on-year; meanwhile buybacks collapsed to zero at two of the four, as shareholders traded near-term cash returns for a long-dated bet on AI infrastructure.
How much did they spend — and where did it go?
The four companies' combined capex hit $496.7 billion in the first three quarters, up from $257.4 billion a year earlier — a roughly 93% increase.
Operating cash flow over the same period totalled about $498 billion. This means → virtually every dollar the businesses generated was ploughed straight back into infrastructure. Almost nothing was left over.
In plain terms = these four companies earned roughly the same amount they spent — profits went to data centres and servers, not to shareholders.
Where did shareholder cash go?
In the first three quarters of 2025, Alphabet and Meta bought back a combined $66.1 billion in stock. In the same period of 2026, both companies' buyback spending fell to zero.
Dividends continued, but buybacks — the larger, more flexible form of cash return — stopped entirely. (A buyback is when a listed company repurchases its own shares from the market and retires them, making the remaining shares more valuable.)
This means → shareholders shifted from "receiving real cash" to "waiting for a future payoff," with near-term returns materially reduced.
How dramatic was Alphabet's reversal?
In early 2025, Alphabet spent $39.8 billion repurchasing its own stock. This June it reversed course, announcing an $80 billion new-share sale framed as AI-infrastructure financing.
Berkshire Hathaway committed to $10 billion of that offering. In Q3 Alphabet raised another $28.7 billion through note issuances and $12.4 billion through a gradual share-sale programme, primarily to cover employee equity-compensation taxes.
In plain terms = Alphabet went from "spending cash to shrink its share count" to "selling new stock to raise cash" — a complete directional reversal. Last year it was retiring shares; this year it is issuing them.
How do the other three compare?
Meta: equipment spending of $83.1 billion against operating cash flow of $96.9 billion — still covered. But the company plans to create a new class of non-voting shares in January 2027, providing capacity for investment, M&A and employee compensation.
Microsoft: the most comfortable of the four — cash flow still comfortably exceeds capex. Buybacks totalled $9.7 billion through September, down from $10.7 billion a year earlier; Q3 alone fell 26% year-on-year to $2.9 billion.
Amazon: capex exceeded operating cash flow, but the company conducted no buybacks in either year, so it did not contribute to the group-wide decline.
What does this mean for shareholders?
The core logic of buybacks is simple: fewer shares outstanding means the same profit is spread across fewer slices, lifting per-share value.
When buybacks stop — or reverse into new issuance — that process runs backward. Per-share equity is diluted before profit growth has materialised.
This reflects a fundamental trade: shareholders are forgoing near-term cash returns, betting that AI infrastructure spending will eventually generate enough incremental profit to compensate for today's dilution.
