Nvidia Tops $5 Trillion, Then Turns Its Guns on the PC Market

Nvidia's ascent shows no sign of slowing. The chipmaker now carries a market value of roughly 5.4 trillion dollars — making it the most valuable company on the planet, nearly a trillion dollars clear of its closest domestic rival — and it is using that dominance to push into new territory.
At the heart of the moment is Rubin, Nvidia's next-generation AI platform. Built around six new chips, the company says Rubin delivers up to a tenfold reduction in the cost of generating AI 'tokens' and can train large models with a quarter of the GPUs its previous Blackwell platform required. For the data-centre customers driving the AI boom, those economics matter enormously.
But the more provocative move is Nvidia's entry into the personal-computer market. A new chip called RTX Spark, developed jointly with Taiwan's MediaTek, is set to appear in Windows machines from Microsoft, Dell, HP, ASUS, Lenovo and MSI — a direct incursion into turf long held by Intel, AMD and Qualcomm. Shares of all three fell as Wall Street registered the threat, with chief executive Jensen Huang openly talking of 'reinventing the PC'.
Nvidia already commands an estimated 85 to 92 percent of the market for AI accelerators, the specialised processors that power modern machine learning. Extending that grip from the data centre down to the laptop on a desk would knit the company into nearly every layer of computing.
For rivals, the message is unwelcome and unmistakable. Nvidia is no longer content to sell the engines of the AI era to cloud giants; it wants a piece of the devices people actually hold. Whether it can dislodge entrenched incumbents in PCs is an open question — but few companies have ever attempted it from a position of such strength.
