Nvidia's $150 Billion Stock Buyback, Explained

Nvidia’s board just approved a new $150 billion increase to its stock buyback program, on top of what was already authorized — bringing the company’s total remaining buyback capacity to $235 billion. The increase, approved Monday, 28 September 2026, is the third such expansion in about thirteen months, and financial news outlets covering the announcement have described it as the largest single stock buyback authorization increase in U.S. corporate history. Here’s what the announcement actually says, how the new $150 billion relates to the $235 billion total, and how much of its buyback Nvidia has already executed.

What did Nvidia just announce?

Nvidia’s board of directors approved an additional $150 billion in share repurchase authorization on Monday, 28 September 2026. The company said in its own newsroom release that it expects to execute its total remaining repurchase program through fiscal year 2028. CEO Jensen Huang tied the move to the company’s cash position: “NVIDIA’s growth is being driven by a once-in-a-generation platform shift to AI and accelerated computing. Our cash generation gives us the capacity to invest in the technologies that advance this transformation and return capital to shareholders. This authorization reflects our confidence in the long-term opportunity ahead.”

Is the $150 billion the same thing as the $235 billion?

No — the $150 billion and the $235 billion describe two different numbers. The $150 billion is the size of the brand-new authorization the board approved on 28 September. The $235 billion is the total amount of stock Nvidia is now authorized to repurchase going forward, once the new $150 billion is combined with whatever remained from its earlier authorizations. Put simply: $150 billion is what changed on Monday; $235 billion is the full remaining pool Nvidia can now draw on. Some headlines compress the two into a single “$235 billion buyback” framing, so it is worth keeping straight that Nvidia did not authorize $235 billion in new spending on 28 September — it authorized $150 billion in new spending, which, added to the leftover balance, produces $235 billion in total remaining capacity.

How does this fit with Nvidia’s earlier buybacks?

This is the third time in roughly thirteen months that Nvidia’s board has added to its buyback authorization.

Each of the three increases was approved “without expiration,” meaning Nvidia sets its own pace for buying back stock rather than working against a deadline.

How much stock has Nvidia actually bought back so far?

Nvidia repurchased 282 million shares for $40.4 billion during fiscal year 2026, then another 108 million shares for $20.2 billion in the first quarter of fiscal year 2027 alone, according to figures in the company’s own financial filings. Those numbers predate the 28 September increase and reflect buying under the earlier authorizations; Nvidia’s next quarterly earnings report will be the first to show how much of the newly expanded $235 billion pool has actually been spent.

Why is this being called the “largest” buyback authorization in history?

That superlative comes from financial news outlets covering the announcement, not from language in Nvidia’s own press release, which states the dollar figures without using that phrase. Outlets covering corporate finance noted that the $150 billion increase is larger than Apple’s widely reported $110 billion buyback authorization from 2024, previously cited as a reference point for the largest single increase by a U.S. company. We’re presenting “largest in history” here as reporting characterization, not as a claim Nvidia itself makes in those words.

What is a stock buyback, and why does a company do one?

A stock buyback is when a company uses its own cash to repurchase shares of its own stock, reducing the number of shares outstanding. Companies use buybacks, alongside or instead of dividends, as one way to return cash to shareholders once a board authorizes a specific dollar amount to spend on repurchases. Nvidia frames this move around cash generation from its AI and data-center business giving it capacity for both continued investment and this kind of capital return. This article describes that announced authorization and its terms; it is not a forecast of Nvidia’s stock price, nor a recommendation to buy or sell the stock.

What happens next?

Nvidia says it expects to execute the full $235 billion in remaining authorization through fiscal year 2028, though a board authorization is a ceiling on spending, not a commitment — the company can buy back more, less, or pause entirely within that window depending on its own decisions. The clearest next checkpoint is Nvidia’s next quarterly earnings report, expected in mid-to-late November 2026 based on its recent quarterly cadence, which should disclose exactly how many shares and dollars went toward buybacks in the period covering this announcement.

Whatever comes of the newly expanded authorization, the figure worth watching going forward is how much of that $235 billion actually gets spent — not the size of Monday’s approval on its own.
