Nvidia opened trading on October 29 as the first publicly listed company ever to touch a $5 trillion market value, and by the closing bell the number felt almost secondary. Shares had climbed roughly 3%, to $207.04, adding tens of billions in a single session — the kind of move that used to define a company’s entire year. For Nvidia in 2025, it was Wednesday.
The arithmetic is worth sitting with for a second. Nvidia hit $4 trillion in July. It hit $5 trillion in late October. That’s a trillion dollars of value in about fourteen weeks, added by a company that ten years ago was best known for graphics cards that made video games look better. Jensen Huang, who has run Nvidia since he co-founded it in 1993, has spent the last three years turning that reputation inside out. The chips that once rendered explosions in shooter games now train and run the large language models eating up headlines, budgets, and — increasingly — entire data center campuses.
Huang didn’t let the milestone pass quietly. Days before the stock crossed the line, he told reporters Nvidia is sitting on roughly $500 billion in AI chip orders and announced plans to build seven new supercomputers for the U.S. government. He also disclosed, almost as an aside, that Nvidia is taking a $1 billion stake in Nokia to co-develop 6G network technology — a deal that would have seemed like a strange detour for a chipmaker five years ago and now reads as fairly on-brand.
Put the valuation next to something familiar and it stops sounding like a headline and starts sounding strange. Five trillion dollars is more than the entire Stoxx 600, the benchmark for European blue chips, combined. It’s more than the total value of every cryptocurrency in existence. Nvidia alone is now worth more than AMD, Intel, Micron, and Qualcomm put together, which is a strange sentence to type about a company whose closest historical peer was a maker of joystick-adjacent silicon.
None of this is happening in a vacuum, and the people paid to be skeptical are, predictably, skeptical. Keith Lerner at Truist Advisory Services told Bloomberg that a number like this “would have been unimaginable a few years ago” — which is true, and also exactly the kind of sentence that gets said right before things either keep going or don’t. Matt Britzman, an analyst at Hargreaves Lansdown, called the moment less a milestone than a statement: Nvidia has gone from chipmaker to the thing an entire industry now runs on. His firm holds the stock, for what that’s worth.
The bubble question isn’t going away just because Huang keeps waving it off. Since ChatGPT launched in late 2022, Nvidia’s stock is up roughly twelvefold. The company’s own numbers back a lot of that — quarterly revenue north of $85 billion, sales growth above 50%, a $10 billion buyback announced alongside the results — but valuations built on the assumption that demand for AI infrastructure keeps compounding at this pace are, by definition, bets on a forecast, not a balance sheet. Hyperscalers like Microsoft, Meta, Amazon and Google are the customers doing the compounding, and they’re spending capital at a rate that would have gotten a CFO fired in 2019.
I’ve covered enough of these moments to know the framing that follows almost automatically: is this 1999 again, is this different this time, cue the dot-com comparison. It’s a lazy comparison, honestly, because Nvidia is profitable in a way that Pets.com never dreamed of being, and the demand driving its order book is coming from companies with the cash to actually pay for what they’re ordering. But lazy comparisons get made because sometimes they’re not entirely wrong, either. The stock’s five-year return — over 1,500% — isn’t a number that survives on fundamentals alone forever. At some point the growth rate has to slow, and the question that actually matters isn’t whether Nvidia is a good company. It obviously is. It’s whether the price already assumes a decade of flawless execution with no bad quarter in between.
Apple crossed $4 trillion the day before Nvidia’s milestone. Microsoft has done it twice. The trillion-dollar club that felt exclusive five years ago is starting to look like a waiting room. Nvidia just walked past everyone else in it, and the next number analysts are already arguing about — quietly, in notes most retail investors will never read — is whether $6 trillion comes before the first quarter that disappoints Wall Street. Huang, for his part, isn’t hedging. He says the company is tracking toward half a trillion dollars in annual revenue. He’s been right before. He hasn’t yet had to be right about everything at once.
