Robust financial performance and strong growth expectations from ASML and TSMC this week boosted sentiment across the tech industry, lifting stock prices and market capitalizations throughout the AI supply chain. Among the most notable beneficiaries of this AI-driven momentum are AMD, with a market capitalization that reached an all-time high on Thursday, and Intel, whose market cap hit a 25-year high. Other notable beneficiaries are Arm Holdings and Nvidia.

AMD's market cap hit $454 billion as its stock price touched $278, an all-time high for the company. Intel continued its rally that began in early March, and its market cap reached nearly $340 billion on April 16 as its stock price tested $68. For Intel, this is its second-best result since August 2020, when its valuation briefly achieved $502.71 billion. Arm has been on the rise since early March; its current market capitalization is $174 billion as its stock approached $165.

All three CPU stocks are driven by AI hype — specifically, rapid adoption of agentic AI and retrieval augmented generation (RAG) systems that benefit from high-performance CPUs and high-bandwidth memory subsystems. While it remains to be seen whether AMD and Intel can actually increase sales of their EPYC and Xeon CPUs tangibly due to the adoption of agentic AI and RAG systems by various parties, it is obvious that both companies benefit from the AI infrastructure buildout and AI adoption by enterprises, as these drive demand for data center-class processors.

If you look at AMD's historical market performance, you'll notice that for roughly 20 years, AMD's market capitalization remained low and volatile, generally in the single-digit to low tens of billions. Peaks around the early 2000s (Athlon era) and mid-2000s (Athlon 64 and Opteron success) were followed by prolonged declines tied to execution issues and performance disadvantages compared to Intel. AMD's inflection started around 2017 with the launch of the Zen microarchitecture as well as EPYC and Ryzen processors on its base, though it was not until around 2020 when the company's market cap hit $100 billion. That was after the market finally believed that the company could execute.

Meanwhile, the majority of AMD's current valuation was created after 2020 and the valuation is based on the market's belief that AMD can benefit from industrial megatrends like AI and cloud computing. So far, AMD has been successful.

When it comes to Intel, its market cap was below its book value last August, but began to climb after the U.S. government, accompanied by SoftBank and Nvidia, injected some cash into the company. To a large degree, the company's current valuation is based on expectations about Intel's ability to execute and sell a boatload of processors for AI systems.

For Arm Holdings — which became a CPU maker a few weeks ago and which gets most of its revenue by licensing CPU technologies rather by selling hardware — the positive sentiment reflects its unique position in the client and AI ecosystems. Arm is the indisputable leader in smartphones and tablets and the rising star in automotive and client PCs. Meanwhile, the Arm ISA has become the architecture of choice for hyperscalers developing custom silicon.

As for Nvidia, its undeniable leadership in the AI infrastructure in general and AI accelerators in particular is driving its market capitalization towards $5 billion. Nvidia's market cap on Thursday reached $4.82 trillion, down slightly from $4.92 trillion on October 21, 2025.

    Seems like I keep writing these to no avail...;) "Market cap" numbers do not tell you about a company, it's size, or it's total capitalization. Market cap is simply a figure that takes the current asking price per share and multiplies it by the total number of shares in circulation. It's an on-paper number that is usually used by brokers to entice the unlearned and/or unwary to use their services to buy the stock, to earn brokerage commissions. So why doesn't market cap describe the size or capitalization of a company? The answer is so simple I'm surprised by how often it is completely misunderstood or misrepresented.

    1) The great majority of the shares used to compile the MC number are not owned by the company--those shares are not assets of the corporation, accordingly. Those shares are owned by the institutions and individuals who bought the stock at whatever price, who own the shares, and if those shares are sold at the MC figure per share, the money goes to the owners of the stock, not to the corporation. As such, they contribute nothing at all to capitalization, since those shares do not put any money into the corporation; and of course, since the majority of those shares are not corporate assets, but are owned outside of the company, they contribute no information as to the size of the company.

    2) Why is MC a theoretical, on-paper number, only? Because every owner of the company's stock would have to sell all of his stock, today, at the current share price. And what happens to the share price of huge volumes of stock put up for sale at the same time? What happens is that the share price begins to fall like a rock in the face of "millions" of shares flooding the market simultaneously. It's a danger signal to investors in the company, in fact. So, For this reason, too, Market Cap is simply an impossible number, and it will never happen that all the outstanding shares will be sold at the same time for the highest asking price...;) That's why the number is misleading to begin with. And, then, as stated earlier, the proceeds from these sales go to the owners of the stock--not the company--so no corporate capitalization takes place.

    3) Companies often do buy back some of their stock, which amounts to money going to the stock owners who sell it back to the company, at a minus to the company's coffers. They do this from time to time to raise the asking share price of the stock, and new buyers of the company stock at the asking share price do actually put money in the company. But this never, ever amounts to all the outstanding shares of company stock being sold immediately at the current share prices used in the MC figures.

    4) Most stock transactions involve institutional and individual buying and selling to and from each other, and when profits are had, they accrue to the owners/sellers of the stocks, not to the company that originally issued the shares. Let's say that I own 5,000 shares of Company A, and that I paid $100 a share for them, and I want to sell 1,000 shares today, and I'm very lucky and get $300 a share for all of them, at that point I make a cool profit per share of $200, even if the asking share price for new company stock is $385 a share. The buyer saves $85 over buying shares directly from the company, and I make my nice profit on selling my shares to him, and the company makes nothing on the sales of those shares. In reality, share price in buying and selling will only amount to whatever the market is willing to pay for said shares at the time--a lot like the difference between realestate appraisals and what someone is willing to pay...;).
