Shares of Nvidia (NASDAQ: NVDA) climbed roughly 2% on Monday after the company announced a $150 billion expansion of its stock repurchase program, raising the total remaining authorization to $235 billion. The stock hovered near the $230 mark following the disclosure.

The chipmaker described the increase as the largest single buyback authorization expansion in its history. The new figure also surpasses the $110 billion repurchase approval Apple received in 2024, undersoring how authorizations of this scale have become a defining feature of capital return among the largest U.S. technology companies.

A buyback returns capital to shareholders by repurchasing stock on the open market, reducing the number of shares outstanding and, all else equal, lifting earnings per share. Companies often pair repurchases with dividends as complementary ways of returning excess cash to shareholders. An authorization itself grants permission rather than an obligation, with the pace of purchases left to management's discretion over time.

Management plans to deploy the entire $235 billion by fiscal year 2028, which concludes in January of that calendar year. That timeline translates to outlays of approximately $40 billion per quarter over the remaining 16-month window, more than double Nvidia's recent repurchase velocity. Over each of the last two quarters, the company allocated roughly $20 billion toward buybacks. Nvidia's quarterly filings, which disclose repurchase activity, will show whether execution tracks that accelerated cadence.

Financial Strength Fueling the Program

The expanded authorization follows a stretch of exceptional cash generation. During the first six months of fiscal 2027, Nvidia produced $69.9 billion in free cash flow, a 77% surge versus the corresponding period of the prior year. The company also delivered $74.4 billion in operating cash flow over the same timeframe. Even with that level of capital deployment, Nvidia still distributed $46.1 billion to shareholders during the period, the scale of cash flow that underpins capital-return programs of this magnitude.

Chief Executive Jensen Huang directly connected the authorization to this robust cash generation, characterizing it as a demonstration of confidence in the “long-term opportunity” presented by artificial intelligence and accelerated computing technologies.

The repurchase announcement coincided with the unveiling of Nvidia's Open Agent Safety Platform, an open-source software framework designed to enhance security protocols for third-party AI agent ecosystems.

Lessons From Previous Buyback Programs

Historical analysis of Nvidia and Apple buyback announcements shows that shares have typically outperformed the S&P 500 in the subsequent 12 months, although the pattern is not without exceptions.

Between 2018 and 2025, Apple approved six separate buyback authorizations of $90 billion or higher. The company's stock posted gains during each of the six subsequent 12-month intervals, outperforming the S&P 500 in five instances.

Nvidia's historical record appears even stronger. Following its $25 billion buyback expansion in August 2023, the stock surged approximately 175% over the next 12 months, while the S&P 500 advanced roughly 27%. After a $50 billion authorization increase in August 2024, Nvidia shares climbed 43% against a 16% gain for the broader index. Last year's $60 billion boost preceded a 26% stock advance, compared with the index's 19% rise.

The pattern does not guarantee success in every scenario. Apple's 2023 buyback occurred amid declining revenue, and its shares underperformed the S&P 500 during that period.

Market observers also highlight valuation as a critical factor. According to a former Wall Street analyst posting on X.com, Nvidia currently trades at approximately 18.7 times forward earnings estimates. A forward earnings multiple measures a company's share price against the per-share profit analysts expect it to report over the coming year. The analyst emphasized that Nvidia is repurchasing its shares at a more attractive valuation multiple than most S&P 500 constituents, and noted that the company maintains the financial flexibility to simultaneously fund AI infrastructure expansion and reward shareholders.

Limited Impact on Outstanding Share Count

Notwithstanding the substantial repurchase volumes, Nvidia's outstanding share count has seen only minimal reduction. Diluted shares decreased by approximately 1% during the past year, while earnings per share more than doubled over the same timeframe. The overwhelming majority of that growth stemmed from operational expansion rather than share count reduction. Stock issuances for employee compensation can also offset repurchases, limiting the net decline in shares outstanding.

Nvidia currently maintains approximately 24.1 billion outstanding shares. At the current price of roughly $230 per share, the company's market capitalization approaches $5.5 trillion, the largest valuation among publicly traded companies. Executing the full $235 billion authorization at prevailing market prices would enable repurchases of slightly more than 4% of outstanding shares.

Nvidia's stock settled at $227.21 by Monday's closing bell, marginally below its intraday peak near $232.82. The company's upcoming quarterly reports will provide the first hard data on how quickly the enlarged program is being deployed, and on how the outstanding share count responds.
