AMD surpassed a $1 trillion market valuation for the first time after its shares jumped 9% to an intraday peak of $613.92, extending a five-day streak that has added about 24% to the stock. The move capped a dramatic run for the chipmaker, whose share price is up more than 180% so far in 2026.
Investors have rallied behind revenue tied to artificial intelligence workloads, with AMD reporting second-quarter sales of $11.54 billion, up 50% from $7.69 billion a year earlier. The company’s Data Center business drove much of that expansion, delivering $6.7 billion in sales, a 107% increase versus the prior year, according to the company’s results.
The stock’s sudden rebound follows a dip last month, when shares fell even though AMD’s Q2 earnings beat expectations. The latest five-day surge has restored momentum and pushed market value above the trillion-dollar threshold, a milestone that underscores investor appetite for firms supplying AI infrastructure.
Despite the jump, AMD remains distant from the sector leader in market value. Nvidia’s market capitalisation sits at about $5.4 trillion, a gap that highlights the scale advantage enjoyed by the top AI chip vendor. Still, AMD’s management has signalled further ambition in data-centre silicon: CEO Lisa Su said on the company’s earnings call last month that it expects to double data centre sales in 2027.
The industry-wide demand for AI chips shows few signs of easing, even as the buildout prompts public debate over data centres and concerns about the safety of large language models. Nvidia’s chief executive Jensen Huang last week characterised silicon demand as robust, saying he expects his company to double the number of chips it sells next year, a projection that points to continued pressure on supply and competition for customers.
For now, AMD’s market-cap milestone reflects investor confidence in its role in the AI hardware cycle and in the rapid expansion of its data-centre business. The next test for the company will be whether it can convert its growth targets into sustained market share gains against larger rivals as chip sales and supply dynamics evolve.
