Advanced Micro Devices shares rose 2.7% in after-hours trading to $554.50 after the company announced a multi-faceted push into AI infrastructure that combined a large supply agreement with Anthropic and a product rollout at its Advancing AI 2026 event in San Francisco.
At the center of the moves is a strategic partnership between AMD and Anthropic. Under the agreement, Anthropic will deploy up to 2 gigawatts of AMD Instinct MI450 Series GPUs in AMD Helios rackscale solutions. The rollout will begin with the first gigawatt in the first half of 2027. As part of the arrangement, AMD agreed to provide up to $5 billion in milestone-contingent equity to take a stake in Anthropic, and Anthropic committed to purchasing tens of billions of dollars in AMD chips over the life of the deal.
In parallel with the supply agreement, AMD used the Advancing AI 2026 conference to unveil its Helios AI Rack and to introduce the MI455 GPU. The MI455 features 320 billion transistors, is produced on TSMC's 2nm/3nm process node combination, and pairs with 432GB of HBM4 memory. AMD said the MI455 delivers dramatically higher performance than its predecessor, and the company offered a market projection that the AI accelerator segment could represent as much as $1.4 trillion by 2030.
Analysts responded to the announcements with more optimistic forecasts for AMD's data center GPU opportunity. Wells Fargo updated its model to project data center GPU revenue of $40.6 billion by 2027, and the firm assigned an Overweight rating with a $615 price target. The Anthropic commitment also raised AMD's total public AI compute pledges to roughly 14 gigawatts across three leading AI customers, a cumulative figure cited by market participants as evidence of growing commercial traction ahead of AMD's upcoming earnings report on August 4.
Bank of America's semiconductor desk also made a related call by adding Micron Technology to its U.S. 1 List with a $1,550 price target, a move characterized by analysts as an endorsement of the broader AI-memory-and-compute stack that AMD anchors through its GPU lineup.
Macro and market context supported the reaction. IDC increased its full-year 2026 forecast for AI infrastructure spending, and the Advancing AI 2026 conference was broadly viewed as a pivotal industry event where AMD was expected to commercially launch the Zen 6 "Venice" EPYC server processor and provide a detailed roadmap update for the MI455X Helios GPU platform. The NASDAQ finished the regular session up 0.4%, while the S&P 500 was essentially flat, underlining that AMD's after-hours move reflected company-specific momentum beyond general market moves. Alphabet's strong quarterly revenue performance also helped lift sentiment across the technology sector.
Together, the supply deal with Anthropic, the MI455 product debut, and a supportive analyst backdrop formed a set of near-term catalysts that investors priced into AMD's after-hours quote. Market observers noted that AMD's willingness to provide equity and to collaborate on software optimization represents a direct strategy to narrow the gap with larger competitors in AI training hardware.
Trading near $554.50 in after-hours — below its 52-week high of $584.73 — the stock appears to reflect investor expectations for continued execution as AMD heads into its August 4 earnings report. While company-specific developments drove the after-hours gain, analysts and investors will watch order flow from announced agreements and the commercial uptake of new hardware to assess whether the momentum persists into the next reporting period.
