AMD's stock has ripped higher this year, up more than 45% and soaring over 80% in the last three months, outpacing Nvidia. MarketBeat credited the jump to early traction for AMD's MI300 accelerators and strong EPYC server demand, reporting the MI300 line hit $1 billion in sales in two quarters. Reuters put Nvidia's year-to-date gain near 36% and highlighted pronounced trading swings. The moves reflect a rotation in semiconductors toward companies with broader product pipelines and recent revenue momentum, and they exposed investor worries about concentration among hyperscalers.

AMD's rally has turned heads on Wall Street. MarketBeat reported that AMD shares are up more than 45% so far this year and have risen over 80% in the last three months, driven in part by early sales of the MI300 accelerator family. MarketBeat said the MI300 line reached $1 billion in sales in two quarters, a milestone the outlet tied to renewed investor confidence in AMD's data center strategy.

Why AMD is surging

MarketBeat's review of AMD's results put numbers on the momentum. The outlet reported a 57% year-over-year increase in AMD's Data Center revenue in the first quarter of 2025, a jump MarketBeat attributed to EPYC server CPUs and Instinct GPUs winning business from AI developers. The Client segment, driven by Zen 5 adoption, showed 68% year-over-year growth, MarketBeat added.

Those figures suggest AMD is converting product launches into tangible revenue, and MarketBeat framed the company's broader pipeline as a structural opportunity. The outlet argued that AMD's mix may appeal to hyperscalers wary of single-vendor concentration, pointing to MI300 and EPYC momentum as concrete drivers behind the stock surge.

At the same time, MarketBeat reported shifts in GPU market share that highlight how the chip market has reordered. MarketBeat said Nvidia remains dominant in desktop and laptop GPUs with roughly 92% share, and it cited an about 80% share for Nvidia in chips used for AI training. AMD's GPU share in those categories sits near 8% after falling from 15% in the fourth quarter of 2024, MarketBeat said. That mix shows AMD still has ground to cover on the GPU front even as it wins new server deals.

Why investors are cautious on Nvidia

Reuters covered the market reaction on a volatile trading day and emphasized a contrasting view of Nvidia. While Reuters described Nvidia's earnings as "stellar," the outlet also highlighted investor concerns over lofty valuations and the company's dependence on a small number of hyperscaler customers.

Mastheads

Reuters quoted analysts and market coverage noting that the pace of hyperscalers' capital spending will be critical to sustaining the wider AI build-out.

Those worries showed up in price action. Reuters reported Nvidia stock swung during the session, climbing as much as 5% before ending the day down about 2.2%. Reuters added that Nvidia had fallen nearly 8% in November while still up roughly 36% for the year. The Philadelphia SE Semiconductor Index was down about 2.8% on the day Reuters covered, and chipmakers including AMD and Micron saw sharp intraday declines of 5.8% and 8.3% respectively as investors rotated positions.

Executives and bank analysts offered differing tones about sustainability. Reuters quoted Nvidia Chief Executive Jensen Huang saying demand was "incredible," and Reuters reported Huang told investors bookings extend into 2026, remarks intended to push back on bubble narratives. J.P. Morgan analysts, Reuters added, framed Nvidia's beat-and-raise as evidence of strong execution across its supply chain.

Still, Reuters' market reporting made clear that volatility can be extreme even for the sector leader. The swings underline the tension between near-term execution and longer-term questions about who will fund the next waves of AI infrastructure.

Regulatory moves added another complicating factor earlier this year. MarketBeat reported that export controls in early 2025 materially affected near-term supply and inventory positions for both firms. The outlet said Nvidia took a $4.5 billion excess-inventory charge after shipments of H20 units to China were blocked from April until July. MarketBeat reported AMD booked roughly an $800 million excess-inventory charge tied to the same restrictions.

Those write-downs show how policy can rearrange the economics of chip cycles. They also feed into investor calculations about which firms can manage supply chains and customer concentration while preserving margins and growth.

The two outlets also diverged on valuation snapshots. MarketBeat framed Nvidia earlier as the world's first $4 trillion company, while Reuters referenced Nvidia crossing a $5 trillion valuation in its most recent run, reflecting different timeframes and valuation snapshots. The difference in headline numbers shows how quickly values can shift in this market, and how different reporting windows can produce contrasting narratives.

For now, AMD's stock momentum is tethered to product wins and revenue growth that MarketBeat documented, while Nvidia's market leadership and execution continue to command attention in Reuters' reporting. The investor rotation has mixed winners and losers within semiconductors, and both public- and private-sector decisions will influence who gains long-term share.
