AMD and Micron could be headed for $2 trillion market caps, says analyst

For most of the AI boom, the chip trade has been a one-name show. That script is getting rewritten.

According to an analyst cited by CNBC, resurgent demand for CPUs and efficiency gains from memory could propel more chipmakers to a $2 trillion market cap. AMD and Micron are the two names in the frame.

The numbers behind the rally

Micron added roughly $920 billion in market value during Q2 2026, a gain of 240%. AMD tacked on about $615 billion, up 186%.

Intel joined the party too, adding around $480 billion for a 216% gain. Together, the three chipmakers added roughly $2 trillion in combined value in a single quarter.

Micron got to $1 trillion first, reaching that mark in May 2026. The memory maker posted revenue growth of more than 400% year over year alongside gross margins of 84.9%.

AMD followed later, crossing the $1 trillion threshold between September 21 and 23, 2026. The move came after the company raised its total addressable market estimate to $2 trillion to $3 trillion by 2030.

Total addressable market, or TAM, is the size of the whole pie a company thinks it can compete for. AMD is essentially telling investors that the data center opportunity for GPUs, CPUs and related hardware is far larger than previously assumed.

Why CPUs and memory are back in fashion

The research findings describe a surge in CPU and memory requirements tied to AI-driven data center expansions. High-bandwidth memory has been a particular driver, lifting both revenue and margins across the sector.

Wall Street has taken notice. UBS analyst Timothy Arcuri set a $670 price target on AMD, suggesting the stock had room to push past a $1 trillion valuation.

Intel’s slower comeback

Intel’s recovery offers a useful contrast. The company has benefited from renewed CPU demand, particularly as AI workloads shift toward edge computing.

Even so, Intel’s valuation recovery has lagged behind both AMD and Micron. Its 216% Q2 gain was impressive in percentage terms, but it started from a lower base and has not matched its rivals in absolute market value.

What this means for the chip sector

AMD’s revised $2 trillion to $3 trillion TAM projection is the clearest signal of management confidence.

But the $2 trillion market cap scenario remains a possibility, not a forecast. The research findings note that no immediate projections point to either AMD or Micron reaching $2 trillion individually or in combination in the near term.

The research findings flag elevated valuations and competitive risks as the key caution flags.

Micron’s 84.9% gross margin is extraordinary by historical memory-industry standards. The question investors will be asking is how durable that figure is once new supply comes online.
