Nvidia's $235 Billion Buyback Plan Exposes an AI Cash Divide in Big Tech

Nvidia Corp. authorized a fresh $150 billion share-repurchase program on Tuesday, bringing its cumulative buyback capacity to $235 billion through January 2028 — a figure that highlights how flush the chipmaker has become while its biggest customers struggle to fund their own AI ambitions.

DataTrek Research co-founder Nicholas Colas framed the gap in blunt terms. "Nvidia is the only U.S. Big Tech company in any real position to increase its stock buyback, which is both good and bad news," he wrote in a Tuesday note. "On the plus side, the world's most valuable company is signaling confidence in its future cash flows. On the downside, its clients cannot express similar faith."

Why is Nvidia buying back stock now?

Nvidia trades at 17x estimated forward earnings — a multiple Colas called cheap but not the real reason for the buyback. Capital allocation, he argued, should follow opportunity, not valuation.

"Managements and boards are in the business of allocating the capital entrusted to them by shareholders," Colas wrote. "When they have opportunities that exceed their cost of capital, they should invest in them. When they run out of those, they should buy back stock."

Nvidia first plowed capital into its core chip business and into an expanding slate of AI-related venture investments, including $18.6 billion in venture commitments over a recent three-month window. The company has effectively acted as a venture capitalist inside the AI value chain, taking strategic stakes in customers and partners. Even after those bets, free cash flow continued to accumulate — leaving the new authorization as the next-best use of cash.

Why have Alphabet and Meta pulled back?

The contrast with two of Nvidia's largest customers is sharp. Alphabet spent more than $15 billion on share buybacks in the quarter ending Dec. 31, 2024, according to FactSet data cited by MarketWatch. A year later, that figure had fallen to $5.5 billion. By early 2026, Alphabet had halted repurchases entirely, posting negative free cash flow in the quarter ending June 30 as data-center and AI infrastructure spending outpaced operating cash generation.

Meta's program has flatlined in similar fashion. After spending more than $10 billion on share repurchases a year ago, the social-media company has not repurchased any stock for the past three quarters.

Both companies are now redirecting cash toward infrastructure. Alphabet is projected to spend up to $205 billion on capital projects in 2026; Meta's infrastructure budget is expected to reach $145 billion.

Who is still returning cash to shareholders?

Microsoft has held a steady capital-allocation posture while scaling its Azure cloud business. Apple has continued its long-running repurchase program, returning $25 billion to shareholders through buybacks in its most recent quarter — a track record that predates the current AI buildout but still anchors Big Tech's return-of-capital tradition.

Whether either company can sustain that pace is an open question. Both face rising AI infrastructure bills of their own, and competitive pressure to keep spending is intense.

How long can the AI capex arms race continue?

Colas described the spending behavior of Nvidia's customers as defensive rather than analytical. "They will therefore invest in anything their competitors are also working to build, even if the potential returns are uncertain," he wrote. "The penalty for falling behind is, in theory, increasing irrelevance and, eventually, bankruptcy."

That calculus explains why Alphabet accepted negative free cash flow and why Meta went three straight quarters without a buyback. Each company is anchoring its survival on out-building the other.

Nvidia's $235 billion authorization may be the clearest signal yet of where AI-related cash flow is concentrating. As long as chip demand outpaces the ability of cloud and platform companies to fund their own infrastructure, the supplier sits in a position no other tech giant can match.
