Advanced Micro Devices (AMD) briefly crossed the $1 trillion market capitalisation mark for the first time on Monday, as investors continued to bet on the chipmaker’s expanding role in artificial intelligence computing.
The milestone comes as AMD accelerates its AI product launches and expands beyond individual chips into complete systems combining processors, networking equipment and related hardware.
The company is also benefiting from rising demand for central processing units (CPUs) used alongside graphics processing units (GPUs) in servers handling AI inference, helping it gain market share from Intel.
AMD shares rose 9% to $610 after reaching an all-time high of $613.92, pushing the company’s valuation above $1 trillion.
AMD’s expansion puts it in closer competition with Nvidia in AI infrastructure, particularly as demand grows for the computing systems required to train and run artificial intelligence models.
The company is also benefiting from demand for CPUs used alongside GPUs in AI inference servers, a market that has helped AMD take market share from Intel.
AMD’s milestone comes amid a wider rally in AI-related stocks as investors focus on continued spending on artificial intelligence infrastructure.
Reuters reported on Monday that major US indexes gained as AI-related stocks advanced, with semiconductor companies among the stronger performers. The rally followed renewed investor focus on signs that spending on AI technology was continuing to expand.
The semiconductor sector supplies processors, GPUs, networking equipment and other infrastructure used in data centres and AI systems.
The latest milestone comes amid a broader run of trillion-dollar valuations among technology companies benefiting from the artificial intelligence boom.
Earlier in 2023, Nvidia crossed the $1 trillion valuation mark. In 2025, Nairametrics reported that the company became the first company to reach a $5 trillion valuation, driven by continued demand for its AI processors and growing influence in data centres and advanced computing.
Investors have continued to pour money into companies linked to the artificial intelligence boom, although the sustainability of that spending has also come under scrutiny.
Nvidia and AMD both declined during the sell-off, while investors also questioned the scale of spending on chips, data centres and other infrastructure supporting the industry.
