On September 28, Nvidia said its board has authorized an additional $150 billion for its share buyback program, taking the total to $235 billion — which the company calls the largest share repurchase authorization increase in history. With AI chip competition intensifying and the stock under pressure, the $5.42 trillion chip giant chose to shout its conviction to the market with cold, hard cash: the AI infrastructure cycle is far from peaking.
A record-breaking declaration of confidence
According to CNBC, Nvidia expects to complete the total remaining buyback program through fiscal 2028. On the day of the announcement the stock rose about 2.8%, capping a roughly 24% gain over the past 12 months and a market cap of $5.42 trillion. Reuters pointed to the other side of the coin: AI chip competition has been weighing on the stock — making this record buyback both an offensive return of capital and a defensive play to stabilize market expectations.
Key numbers (cross-verified)
· Buyback: additional $150 billion authorized, $235 billion total — the largest single authorization increase in history (CNBC/AP);
· Valuation: market cap around $5.42 trillion, up 24% over 12 months, +2.8% on announcement day (CNBC);
· Demand side: S&P Global projects combined hyperscaler capital expenditure to exceed $1.3 trillion by 2027;
· Supply commitment: Jensen Huang said earlier this month that Nvidia will double the number of chips it sells in 2027;
· Product depth: beyond Grace Blackwell and Vera Rubin systems — CPUs, switch chips, optical networking chips, Jetson chips for robots and cars, and even the chip inside Nintendo's Switch 2.
"I think we're going through the largest infrastructure build-out in human history, and we have the benefit of being a very central part of that. We're going to generate a lot of cash in the coming years, and every single year, as we generate more cash, we'd like to be able to return it back to shareholders." — Jensen Huang, CEO of Nvidia
The cash cow's offense and defense
Nvidia's logic is straightforward. On the demand side, the hyperscaler capex curve keeps steepening — "$1.3 trillion by 2027" implies a multi-year boom in data centers, compute and the semiconductors that power them. On the supply side, Huang offered a quantified pledge: chip shipments will double in 2027. The other meaning of the buyback is hedging the competition narrative — AMD's pursuit and hyperscalers' in-house silicon are both eroding Nvidia's monopoly premium, and proving free-cash-flow quality via the largest buyback in history is the most direct language available.
What it means for enterprise users
For the supply chain, trillion-dollar-scale capex means multi-year visibility for compute, cooling and data center construction. For enterprise AI applications, it means the unit-cost curve of inference compute is still on a downward path — the scaling window for compute-intensive applications is opening.
