Nvidia Just Authorised $235 Billion of Buybacks. Spending It on Schedule Means Twice Last Quarter's Pace, Every Quarter, Until 2028.

On 28 September 2026 Nvidia announced a $150 billion increase to its share repurchase authorisation, leaving $235 billion to be used through fiscal 2028. Reuters noted that this passes Apple's $110 billion approval in 2024 as the largest on record. The headline invites a simple reading: a very profitable company is returning cash. The more useful reading is arithmetic. Nvidia says it expects to execute the full remaining programme by the end of fiscal 2028, which closes in late January 2028. That is six quarters, and $235 billion over six quarters is about $39 billion a quarter. In the quarter that ended 26 July, Nvidia paid $19.7 billion for repurchases.

What was actually authorised

An authorisation is a ceiling, not a commitment. Nvidia's press release says the company expects to use the full amount through fiscal 2028, and it gives no quarterly schedule. It also does not say how much was left before the increase; Reuters, reporting the same day, made the same observation. Nvidia's own filings allow an estimate. Its second-quarter fiscal 2027 earnings release put the remaining authorisation at about $99.0 billion at quarter end. Adding $150 billion gives $249 billion, so the $235 billion now reported implies roughly $14 billion of repurchases between the end of July and 28 September. That is our inference, not a reported figure, but it is consistent with a pace near $20 billion a quarter.

Jensen Huang, quoted in the release, said that Nvidia's growth is being driven by a “once-in-a-generation platform shift to AI and accelerated computing”. The release does not say how the money will be found.

The run-rate arithmetic

Nvidia's earnings release for the July quarter (filed with the SEC) supplies the comparison figures. Revenue was $96.2 billion, up 106% from a year earlier. Operating cash flow was $24.1 billion and free cash flow was $21.3 billion. Nvidia paid $19.7 billion for repurchases and $6.0 billion in dividends, about $26.0 billion returned to shareholders in total.

• Pace implied by the authorisation: $235 billion ÷ 6 quarters = about $39.2 billion a quarter (our arithmetic).
• Last quarter's repurchase payments: $19.7 billion, so the implied pace is 1.99 times as fast.
• Last quarter's free cash flow: $21.3 billion, so the implied pace is 1.84 times free cash flow, before any dividend.
• Last quarter's total return (buybacks plus dividends): about $25.7 billion, or 121% of free cash flow.

Put differently, at July-quarter free cash flow it would take about eleven quarters to spend $235 billion, not six. Bram Berkowitz of the Motley Fool arrived at the same figure of more than $39 billion a quarter; both calculations are the writers' own and neither is a company commitment.

What it would be funded from

Reuters cited Nvidia's cash and cash equivalents of $22.44 billion at quarter end, and that number alone makes $39 billion a quarter look unfundable. The filing shows a larger balance sheet. Alongside $22.4 billion of cash, Nvidia held $76.9 billion of marketable securities: $34.1 billion of debt securities and $42.8 billion of equity securities. Total liquidity of about $99.3 billion covers well under half of $235 billion. The $42.8 billion in equity securities is also marked to market, so its value moves with share prices; Nvidia has not said it plans to sell any of it for buybacks.

The programme therefore depends on cash generation, not on cash on hand. Motley Fool reports Nvidia's guidance for roughly 70% growth in fiscal 2028. If free cash flow grows with revenue, later quarters can carry more than July's $21.3 billion. But to fund a $39 billion average from free cash flow alone, it would need to run, on average, at about 1.8 times the July-quarter level across the six quarters. Otherwise the gap comes from the balance sheet or from borrowing, and the filing already shows the company returned more than its free cash flow in July.

The margin line matters more than the headline

Free cash flow depends on gross margin, and gross margin is guided down. Nvidia's release guided third-quarter fiscal 2027 gross margin to 74.0%, plus or minus 50 basis points. Motley Fool reports that the CFO, Colette Kress, expects gross margin to fall to roughly 71% to 72% by the fourth quarter of fiscal 2027, mainly because memory costs are higher, from about 74.7% now. At July-quarter revenue of $96.2 billion, each percentage point of gross margin is worth about $0.96 billion of gross profit a quarter, so a three-point decline would be roughly $2.9 billion a quarter. That is an illustration at constant revenue, not a forecast, and by itself it is small beside the repurchase gap. What it shows is direction: cash generated per dollar of revenue is guided lower in the same period the authorisation steps up.

The case against reading it as a vote of confidence

Large repurchases are usually read as bullish, and the Motley Fool piece says so. Reuters quoted analysts with a more mixed emphasis. Jacob Bourne of Emarketer said Nvidia is signalling confidence in demand for its hardware and services, and added that “the AI buildout won't continue at its current pace forever.” Ben Barringer of Quilter Cheviot, in Reuters's account, compared the move with Apple's use of buybacks to support its stock as growth slows. Reuters also reported that shares rose more than 2% on the news and that the stock was up just over 20% for the year through Friday, trailing AMD and Intel.

The argument against is opportunity cost. Berkowitz flags risks tied to AI capital spending, circular financing deals and margin pressure, and describes the valuation, about 24 times forward earnings by his count, as not demanding. The authorisation equals about 4.3% of a market capitalisation the Fool puts at $5.5 to $5.6 trillion. Every dollar spent on repurchases is a dollar unavailable for supply commitments, customer financing or acquisitions. We examined Nvidia's customer-financing model in August; the two uses of cash are not necessarily either-or, but they draw on the same free cash flow.

What the evidence does not establish

Nvidia has published no schedule, no split between buybacks funded by cash flow and by securities or debt, and no statement of how much of the programme is intended to offset stock-based compensation rather than shrink the share count. The July earnings release does not disclose the number of shares repurchased. Authorisations of this kind can also be left partly unused if the share price or the company's priorities change; the press release commits Nvidia to nothing.

The test is the next set of quarterly figures. A repurchase total near $39 billion would suggest the company intends to execute on the schedule it described. A total near $20 billion would suggest the authorisation is functioning as a ceiling, with the pace unchanged from July.
