AMD Crosses $1 Trillion for the First Time as Meta's Muse Sparks a Chip Rally

Advanced Micro Devices crossed $1 trillion in market value for the first time on Monday, a mark the chipmaker reached in afternoon trading as its shares climbed 8% to $606.72. AMD did not get there alone. A rally ran through the whole semiconductor group.

The spark was Meta’s Muse. Muse is an AI agent Meta released this month, and it has topped Apple’s U.S. list of free iPhone apps for three straight days, according to Barron’s, citing Sensor Tower data. Agents like it carry out multi-step tasks for a user, from comparing prices across websites to working through an inbox, and that kind of orchestration leans on central processors, not only the graphics chips that power AI training. The logic caught on fast. As investors weighed what mass adoption of such agents would mean for data centers, money moved into the companies that sell server CPUs.

The group moved together. Intel rose 12% and Arm climbed nearly 16%, while Qualcomm added 8%, all lifted by the same read on inference demand. Reuters cast chipmakers as the force behind broad gains in global stocks, with oil prices sliding at the same time. For AMD, the round number carried extra weight. Monday’s push briefly made it the seventh chip stock ever to top the level, according to Dow Jones Newswires.

The advance capped a steep late-summer run and extended a five-day climb, by CNBC’s count. AMD shares have gained 29% over the past 30 days and 36% over the past three months, and Monday’s move carried them to a record, with the intraday high just under $616. Volume told the same story. Trading ran 1.6 times the stock’s 20-day average, heavy enough to signal real conviction behind the move. The stock has come a long way, its 52-week low of $76.48 now a distant memory. The strength was market-wide. The Nasdaq Composite rose 2% toward a record and the S&P 500 added 1.4%. The Dow lagged, up 0.7%. Treasury yields eased, with the 10-year note at 4.94%, and the market’s volatility gauge stayed subdued at about 15.

Not everyone is convinced. The bet embedded in Monday’s tape is that consumer AI agents translate into a wave of new server orders, and that link is still a forecast. Arm has estimated the server CPU market could reach $120 billion by 2030, a number that assumes exactly the shift traders are now paying up for. If those apps stall, or lean on the accelerators already installed, the projected CPU demand may not materialize.

The close is the first test. A trillion-dollar tag held for a few midday minutes is not the same as one confirmed at 4 p.m.; the stock ended last week just shy of the mark. Beyond today, the durability of the move rests on adoption figures for Muse and its rivals, the chipmakers’ next earnings updates, and whether the broader AI trade keeps widening. Monday’s turnover, running well above the recent norm, showed how much cash was willing to chase that question in a single session. For one afternoon, at least, the market handed AMD a number it had never worn.
