Nvidia Just Crossed $5.7 Trillion — and Bought $150B of Itself
October 4, 2026 · 5 min read
Nvidia crossed a line this week that no company has ever crossed. On Friday, October 2, the chipmaker's shares climbed nearly 3% intraday to a fresh record, pushing its market capitalization past $5.7 trillion — the first time any public company has gotten there. The stock finished the session at $233.95 a share, worth roughly $5.65 trillion at the closing bell. It was the intraday peak that made the headline: for a few hours on a Friday afternoon, a number everyone had been treating as a distant milestone simply became a fact. (CTEE / 工商时报)
To put that in perspective: $5.7 trillion is larger than the annual GDP of almost every country on Earth. And the next round number — $6 trillion — is no longer a thought experiment. Nvidia is one strong quarter away from it. The question hanging over the market has quietly changed from "is this real" to "how far does this go." Round numbers like this tend to act as magnets: once $6 trillion is in the conversation, every earnings call and every chip shipment gets measured against it.
The $150 billion message
Buried in the same week's news was a quieter announcement carrying its own weight: Nvidia added $150 billion to its share repurchase program, bringing the total authorization to $235 billion, all of it to be executed before the end of fiscal 2028.
A buyback of that size is management talking with the company's wallet. It says, in effect: even at record highs, we think our own stock is still cheap. It also puts a floor under the shares — every dollar spent is real, persistent demand. When a company buys back $150 billion of itself, it isn't trading its own stock. It's voting with its own cash. Buybacks also quietly concentrate ownership: every share Nvidia retires makes the remaining ones a slightly bigger slice of the same machine.
How we got here: up 23% since July
This didn't come out of nowhere. Nvidia has rallied roughly 23% from its late-July low and is up about 25% so far this year. The latest leg got a push from the macro side: a weak nonfarm payrolls report cooled expectations of an October rate hike, and that was a green light for tech stocks across the board. Rate-cut hopes have a way of doing more for mega-cap tech than any single product launch: cheaper money means investors will pay more today for growth that only arrives years from now.
Buybacks don't build the foundation
Here's the part worth slowing down for. A repurchase program makes each remaining share more valuable, but it doesn't create a single new customer or sell a single new GPU. The foundation under this entire rally hasn't changed in two years: exploding demand for AI compute. Data centers are still ordering chips faster than they can be built. If that capital spending ever hits the brakes, the $5.7 trillion arithmetic changes quickly — and no amount of buybacks can paper over a demand slowdown. The bull case for this stock has never been about financial engineering; it has always been one question: do the world's data centers keep buying? So far, they have.
What to watch next
None of this is investment advice — we don't do that here. The honest way to read this story is as a gauge of where the AI trade stands right now: the market believes the compute boom has further to run, and Nvidia's management is willing to stake $150 billion of company money on being right.
So the open question isn't really about the next hundred billion in market value. It's simpler than that: how long can the world's appetite for AI chips keep growing at this pace? That's the only number that decides what happens next — and nobody, not even Nvidia, can answer it for you.
