- AMD shares jumped almost 10% on September 21st, extending a five-day winning streak. The stock's climbed roughly 30% over the past month and more than 180% year-to-date
- This growth comes from AI optimism, the company's Taalas acquisition, and reports of pricing power through a Q4 price hike
- Investors seeking pure upside velocity in AI hardware expansion might favor high-beta AMD. Those prioritizing higher profit margins and CUDA ecosystem dominance should look to Nvidia
Advanced Micro Devices (AMD) stock has been on a scintillating run in recent trading sessions. On September 21, 2026, the stock climbed nearly 10%, closing at $615.52. This pushed the company’s market capitalization over $1 trillion, a first for them.
The stock’s recent climb capped a five-day rally, adding up to about a 30% gain over the last month. So far this year, AMD’s stock is up more than 180%, easily outperforming broader market indexes.
Investors are wondering what’s behind this continued momentum. They’re asking what helps AMD stand out in the semiconductor industry, and if its stock is a better bet than Nvidia’s for the rest of 2026.
What’s Fueling AMD stock Massive Rally?
AMD stock is soaring because of its pricing power and more major cloud providers adopting its tech. Reports indicate AMD raised prices by 10% on its data center products. This isn’t just about passing along higher costs, and market observers see it as real pricing power.
Management points to quicker deployment of its Instinct accelerators and consistent market share gains for its EPYC server processors. Major clients, including OpenAI, Meta, Oracle, and Anthropic, have already committed to large capacity orders.
AMD also announced it’s acquiring Taalas, a company focused on AI inference silicon. This shows AMD plans to compete beyond just AI chip training. Demand for AI infrastructure remains a key driver.
In its second-quarter earnings report, AMD posted total revenue of $11.54 billion, a 50% jump from the previous year. The data center segment, now accounting for over half of all sales, saw a significant 107% surge, reaching $6.7 billion.
AMD’s X-Factor Provides Cushion
AMD’s big edge is its ability to provide high-performance CPUs and AI accelerators in integrated systems.
Unlike Nvidia, which earns over 90% of its revenue from data center GPUs, AMD has a broader business, covering CPUs, GPUs, embedded chips, and gaming silicon. The data center segment makes up roughly 50% to 60% of AMD’s revenue.
This diversified business offers AMD a buffer if capital expenditure on AI initiatives slows down. Its stronger focus on inference, bolstered by the Taalas acquisition, targets the next wave of AI spending.
This next wave will prioritize cost-effective, efficient model execution and training. AMD has pointed to its accelerators’ higher memory capacity and claims better performance per dollar for specific workloads.
Is AMD the Better Buy than Nvidia in 2026?
Year-to-date, AMD stock has risen over 180% while Nvidia stock is up by a much lower 19%. However, Nvidia still has clear advantages, with scale, a mature software ecosystem, and its current lead in data center revenue. Its market capitalization is still considerably larger, and its CUDA platform remains the foundation for most AI developer workflows.
But AMD could see higher percentage gains as it grows its market share in AI accelerators and server CPUs. Cloud service providers often want multiple suppliers, and AMD’s Instinct lineup provides competitive value.
For investors focused on growth, AMD is a high-beta challenger in an expanding market. However, with net profit margins exceeding 50% and gross margins around 75%, Nvidia remains a lower-risk, highly profitable core holding.
Ultimately, the choice between the two companies depends on an investor’s time horizon and risk tolerance. Both stand to benefit from ongoing investment in AI infrastructure, though their risk-reward profiles are quite different.
AMD stock jumped after reports surfaced about higher data center chip prices and major cloud providers deploying more AI accelerators.
AMD sells integrated systems that combine high-performance server processors with AI accelerators. This setup lets them capture spending across training, inference, and host compute tasks simultaneously.
Nvidia operates on a larger scale, boasts a more developed software ecosystem, and leads in AI accelerator sales. These attributes often make it appear a safer investment.
