AMD’s surge beats Nvidia in 1H26 returns, but valuation raises the bar for 2H26

Advanced Micro Devices, which helped drive the AI-chip boom, outperformed Nvidia in the first half of 2026, according to a market recap published Tuesday. AMD shares were among the top performers in the S&P 500, rising about 142% year-to-date, while Nvidia gained just over 4% in the same period.

The rally, the article said, is tied to AMD’s recent financial performance and its growing share in the artificial intelligence infrastructure market. It pointed specifically to demand for AMD’s Instinct GPU accelerators, describing them as a continuing beneficiary of broader spending on AI data-center buildouts.

On the company execution side, the piece cited AMD’s latest quarterly results as “solid,” saying revenue climbed 38% year-over-year to $10.3 billion. It linked that trend to the durability of customer orders for AI compute and to expectations that AMD can continue to take design wins as AI workloads expand.

The article also argued AMD may benefit as the industry shifts from primarily training large models to running more inference, where the models are used to generate outputs. It further referenced the rise of agentic AI, which it described as workloads that demand more compute capacity, giving AMD opportunities across both GPU accelerators and central processing units used in servers.

For 2H26, the market recap framed AMD’s outlook around the idea that its GPUs and its EPYC processor line (AMD’s server CPUs) could both see strength. It suggested that as AI workloads evolve, demand for high-performance EPYC chips could rise in parallel with accelerator demand, supporting a multi-year growth path.

Even with those tailwinds, the post said AMD is not trading cheaply. After the sharp run-up, it reported AMD at 87.9 times forward earnings, a substantial premium to Nvidia’s forward price-to-earnings ratio of about 22.7 times. The underlying message for 2H26 is that higher expectations increase the market’s sensitivity to any slowdown in orders, margin pressure, or delays in deploying new systems.

In response to that tension, the article argued that the valuation may be supported if AMD maintains momentum in AI accelerators and if its CPU business has enough room to expand. It also pointed to the company projecting robust growth over the next three to five years, although it did not provide detail on assumptions behind that range.

Notably, beyond the valuation and high-level demand discussion, the post did not offer specifics on near-term catalysts for 2H26 such as new product launches, customer contract wins, or guidance updates, and it did not quote AMD on what it expects from the second half. As a result, investors looking for clarity on timing and magnitude of growth will likely need confirmation from AMD’s next earnings materials and any public guidance updates.
