AMD Stock Jumps on Major Anthropic AI Deal and New MI455 GPU Reveal

Advanced Micro Devices (NASDAQ: AMD) stock gained 2.7% in after-hours trading, reaching $554.50, after the company announced a landmark artificial intelligence deal with Anthropic and revealed its next-generation AI hardware at its Advancing AI 2026 conference.
Landmark Partnership with Anthropic
AMD and AI firm Anthropic announced a strategic partnership that includes a massive deployment of AMD's AI accelerators. The deal reinforces AMD's growing position as a key hardware supplier for frontier AI model development.
Key terms of the agreement include:
- Anthropic will deploy up to 2 gigawatts of AMD Instinct MI450 Series GPUs.
- AMD will make a milestone-contingent equity investment of up to $5 billion in Anthropic.
- Anthropic committed to purchasing tens of billions of dollars in AMD chips over the deal's term.
According to the announcement, this agreement brings AMD’s total announced AI compute commitments to approximately 14 gigawatts across three major AI companies, signaling significant momentum in challenging Nvidia's market dominance.
Next-Generation Hardware Unveiled
AdAt its conference in San Francisco, AMD also provided a detailed look at its future product roadmap. The company unveiled its new MI455 GPU, a powerful accelerator built on TSMC’s 2nm/3nm process technology. The new chip features 320 billion transistors and 432GB of HBM4 memory.
Alongside the new GPU, AMD showcased its Helios AI Rack solution. The company projects the total addressable market for AI accelerators will reach $1.4 trillion by 2030, underscoring the scale of the opportunity it is targeting.
Market Reaction and Outlook
The after-hours stock gain came after a regular session where the S&P 500 was flat and the NASDAQ Composite rose just 0.4%, indicating the move was driven by company-specific news. The announcements provide a strong tailwind for AMD heading into its August 4 earnings report.
Analysts reacted positively to the developments. Wells Fargo reiterated its Overweight rating and $615 price target, projecting that AMD’s data center GPU revenue could reach $40.6 billion by 2027. The news positions AMD as a strengthening competitor to Nvidia in the high-stakes AI training hardware market.
