SUNDAY, OCTOBER 4, 2026 — Nvidia has done something no American company has ever done. On Monday, the chip giant's board authorized an additional $150 billion in share repurchases, bringing the total remaining under its buyback program to $235 billion through fiscal 2028, which ends in January of that year. It is, by every available measure, the largest buyback authorization in U.S. corporate history.
The previous record holder was Apple, which announced a $110 billion repurchase authorization in May 2024, according to data from Birinyi Associates cited by MarketWatch. Nvidia's new authorization exceeds that figure by $40 billion — and it arrived only months after the board had already approved an additional $80 billion for share repurchases in May of this year, TechRepublic reported.
The market noticed. Nvidia's stock rose nearly 2% on the announcement day, and the shares touched a record intraday high of $237.39 later in the week, capping a rally that has the chipmaker trading at roughly 30 times trailing earnings with forward valuation metrics lower still.
What a buyback actually does
A share-repurchase authorization gives a company permission to buy back its own stock on the open market — it is a ceiling, not a schedule. No company is obligated to spend a specific amount, and Nvidia disclosed no fixed timeline for execution beyond saying it expects to work through the remaining program through fiscal 2028. When companies do execute, the effect is mechanical: fewer shares outstanding means each remaining share represents a larger claim on earnings, which tends to boost earnings per share.
Companies typically buy back stock to return cash to investors, and they often do so when executives believe shares are undervalued. In Nvidia's case, the message is broader than the stock price. "Our cash generation gives us the capacity to invest in the technologies that advance this transformation and return capital to shareholders," CEO Jensen Huang said in the company's release. "This authorization reflects our confidence in the long-term opportunity ahead."
The cash story behind the number
A $150 billion authorization is not a number a company can reach without extraordinary cash generation — and that is precisely the point the market took from it. Nvidia is the primary supplier of the chips powering the artificial-intelligence infrastructure build-out, and demand has been so strong that the company has been able to fund both heavy internal investment and historic shareholder returns at the same time.
"Nvidia's growth is being driven by a once-in-a-generation platform shift to AI and accelerated computing," Huang said in the company statement, framing the buyback as evidence that the AI economy is producing cash faster than even Nvidia can reinvest it.
That reading was echoed on Wall Street. "Nvidia's cash flow is becoming the real flex" for the company, and the stock's momentum following the announcement shows "investors are starting to get the message," Matt Britzman, a senior equity analyst at Hargreaves Lansdown, said in emailed comments to MarketWatch. David Wagner, head of equity at Aptus Capital Advisors, told MarketWatch that the fact Nvidia can ramp spending to "unprecedented" levels while returning cash at historic scale tells investors it "sees the current AI buildout as durable rather than a short-term spike." The announcement, Wagner added, sends an upbeat message about the AI trade "at a moment when AI bubble concerns have been resurfacing."
A widening divide in Big Tech
One of the sharper analyses of the announcement came from Nicholas Colas, co-founder of DataTrek Research, who argued the buyback underscores a growing split between Nvidia and the rest of the technology industry. "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," Colas wrote in a 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."
Colas pushed back on the idea that the buyback means management thinks the stock is cheap — although he noted Nvidia trades at about 17 times estimated forward earnings, a modest multiple for a company of its growth profile. "Managements and boards are in the business of allocating the capital entrusted to them by shareholders," he 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." Translation: Nvidia has more cash than high-return places to put it, which is the best problem a company can have.
What to watch next
The authorization sets the ceiling; the spending pace will decide how much of it becomes reality. The next real checkpoint is Nvidia's fiscal third-quarter earnings report, where the repurchase line in the filing will show whether the company is buying at a daily clip. Investors will also be watching the broader earnings season for confirmation that the AI infrastructure demand behind Nvidia's cash machine is still accelerating — a record share of S&P 500 companies just issued profit forecasts above Wall Street's expectations, with tech and AI-linked chipmakers leading the optimism.
For now, the signal is unmistakable. The world's most valuable company is generating so much cash from the AI build-out that it can fund its growth ambitions and still write the biggest buyback check in American corporate history. On Wall Street, that is not a bubble trade. That is a balance sheet talking.
