Nvidia's Record Buyback Sends a Signal — to Seoul as Much as Wall Street

The Number That Outgrew Its Own Myth

Nvidia’s board approved an additional $150 billion in share buybacks, pushing the company’s total authorization to $235 billion through fiscal 2028. In dollars, it is the largest corporate buyback in US history — surpassing Apple’s $110 billion program announced in 2024. The stock rose more than 2 percent after the disclosure. Wall Street called it confidence. Korea called it something else.

In Seoul, where retail investors funneled record sums into US semiconductor ETFs and direct Nvidia positions last year, the buyback landed not as dry corporate finance but as a status symbol. Financial outlets like AI Times, which broke the story, framed it as a reassurance to a domestic investor base that had watched its Nvidia holdings lag even as the company’s fundamentals expanded. That framing is the point. This move is as much about managing expectations in markets far from Silicon Valley as it is about returning capital.

The Valuation Gap That Bothered Everyone

Nvidia shares have climbed roughly 20 percent year to date. AMD has more than doubled. Intel has more than tripled. Nvidia’s forward P/E sits at approximately 16.5 times — the lowest reading since January 2015 and nearly half its 15-year average of 30 times. The market is pricing the stock as if the AI infrastructure buildout is already hitting a wall, even as the company just reported $96.2 billion in quarterly revenue and projects roughly 70 percent revenue growth through fiscal 2028.

That gap between narrative and numbers is what investors in Seoul and elsewhere are trying to close. The buyback is a tangible gesture: here is cash, here is scale, here is a commitment that this stock is undervalued relative to the cash it will generate. Jensen Huang said it directly, invoking the language of generational platform shifts and the company’s ability to invest in the future while still returning capital. Translated for retail: the company that built this cycle is betting it hasn’t finished.

The Korean Bet, in Plain Sight

South Korea’s retail investor class has become unusually concentrated in American tech. Brokerage data from the past two years shows some of the strongest flows into US-listed semiconductor names relative to domestic alternatives among major Asian markets. The dynamic is simple: domestic equities offer lower multiples and thinner growth narratives, while US AI names offer the only visible path to outsized returns for smaller accounts chasing compounding.

That concentration creates vulnerability. When Nvidia stumbles — and it has stumbled in relative terms, underperforming peers this year — Korean portfolios feel it disproportionately. The buyback announcement arrived in a news cycle where Seoul’s financial media had been asking whether retail investors were being left behind by a rally that no longer included their biggest holding. The $235 billion authorization answers that question before it can fester. It is a signal to a constituency that has no board seat but has enormous voting power at brokerage windows.

The Real Story Is Cash, Not Shares

The buyback is the headline, but the engine is free cash flow. Nvidia generated roughly $100 billion in free cash flow last fiscal year and is projected to reach about $329 billion by fiscal 2028. The buyback is financially trivial relative to that cash generation. What matters is the trajectory. The company is telling the market it expects to sustain hyper-growth long enough to fund a massive repurchase without touching leverage.

It is also deploying that cash in ways that reinforce the moat. The investment portfolio now includes 13 public companies and 229 private ones. Huang has spoken about doubling AI chip volume by 2027. Nvidia is moving beyond GPUs into CPUs, networking chips, optical communication silicon, robotics and automotive processors. It has signed roughly $20 billion in long-term data center lease agreements. It is exploring partnerships with Wall Street banks to partially guarantee up to $500 billion in data center financing.

That last item deserves scrutiny. A structure in which Nvidia helps finance the very customers who buy its chips raises familiar concerns about circularity: the company lends support to demand, then sells into that demand. The analogy to Apple’s buyback strategy is apt but incomplete. Apple bought back shares when growth slowed. Nvidia is buying back shares while growth accelerates — which makes the move either remarkably confident or dangerously presumptive, depending on which risk you weight more heavily.

The Competition Is Not Quiet

The reason the buyback draws attention is the same reason it was necessary. AMD is gaining share. Google is expanding its custom silicon. OpenAI, Anthropic and SpaceX are investing billions in proprietary infrastructure. Chinese manufacturers are pushing low-cost AI chips and open-weight models that compress margins elsewhere in the stack. None of this has dented Nvidia’s dominant position yet, but the competitive architecture is shifting from a single-vendor monopoly toward a fragmented ecosystem where Nvidia remains the default but not the only option.

JPMorgan analyst Harlan Wong, cited in the source material, argued that the buyback signals deep conviction in the durability of demand for Nvidia’s hardware and services. That is a defensible read. It is also a read that assumes the current pace of AI infrastructure spending does not normalize. History suggests it will. The question is when, and how abrupt the transition is.

Who Wins, Who Loses, What Happens Next

Winners: Nvidia shareholders, especially those who held through the relative underperformance of 2025 and early 2026. The buyback reduces share count and supports earnings per share regardless of revenue trajectory. Retail investors in Korea and elsewhere who use US semiconductor ETFs get a psychological lift that may translate into renewed inflows.

Losers: Anyone expecting the buyback to change the competitive dynamics of the AI chip market. It won’t. It changes the capital structure, not the technology stack. It also benefits incumbent shareholders at the expense of any capital that might have gone toward M&A or further R&D expansion — though Nvidia’s cash position makes that tradeoff largely symbolic for now.

What happens next: Expect Nvidia to buy back shares aggressively through fiscal 2028, likely at a pace that outstrips the headline $235 billion authorization if the board feels the P/E remains depressed. The real test will come when AI capex growth decelerates — a timing the market cannot yet price. If free cash flow holds and the buyback continues, the stock becomes harder to short. If the deceleration arrives sooner than expected and the buyback is the only thing keeping the multiple from collapsing, the narrative flips fast.

For Korean investors, the buyback is a reminder that proximity to American tech is both opportunity and concentration risk. The capital returned to shareholders is real. The exposure to a single cycle, a single company, a single currency, is also real. Nvidia is betting it has more cycle left. The market will decide by fiscal 2028.
