Advanced Micro Devices (AMD) has reached a $1 trillion market capitalization, driven by a nearly 200% rise in its stock price this year. This performance makes AMD the ninth-best-performing stock in the S&P 500, though it remains significantly smaller than its primary competitor, Nvidia, which is valued at $5.5 trillion.
The two companies are competing for market share in the artificial intelligence sector, primarily through graphics processing units (GPUs) and data center infrastructure. Nvidia established an early lead in 2023 with superior hardware and software ecosystems. AMD is working to close this gap by releasing new GPUs and improving its programming software to compete with Nvidia's CUDA platform. These efforts have contributed to strong financial growth for AMD, with data center revenue rising 107% year over year to $6.7 billion in the second quarter. Total company revenue increased 50% to $11.5 billion during the same period.
Nvidia continues to outpace AMD in both size and growth rate. Its data center division grew 117% year over year to reach $89 billion, more than ten times the size of AMD's corresponding division. Nvidia's overall revenue rose 106% to $96.2 billion, aided by lower exposure to consumer and original equipment manufacturer demand compared to AMD.
Despite AMD's growth, its current valuation is considered elevated relative to its earnings. The stock trades at 158 times trailing earnings and 81 times estimated 2026 earnings. Even when using 2027 projections, AMD trades at nearly 40 times forward earnings. In contrast, Nvidia trades at less than 30 times trailing earnings and 14.7 times forward earnings based on next year's projections.
This valuation gap suggests that much of AMD's recent stock success is driven by rising multiples rather than genuine business performance improvements alone. The source argues that the market may be overvaluing AMD while undervaluing Nvidia, creating a potential investment opportunity for those who shift capital from AMD to Nvidia. If both companies were to trade at similar trailing earnings multiples of around 30 times, AMD investors might face approximately 25% downside, while Nvidia investors could see their holdings double.
AMD is currently about one-fifth the size of Nvidia and has not yet captured significant market share from its rival. However, the market has priced AMD's stock as if it has already won the competitive battle. The source contends that this mismatch between valuation and fundamental performance is unsustainable and that Nvidia represents a more stable investment position as the market adjusts to these realities.
