Few artificial intelligence (AI) stocks have seen more capital pile into them in such a short period than Micron Technology (MU 3.15%). The memory-chip maker has seen its stock soar 250% since the start of September, and now sports a market cap of over $460 billion.
With the stock already 44% higher through the first few weeks of 2026, investors may be wondering whether it's set to surpass $1 trillion in the near future. Another doubling will just about do it.
Stock prices are forward-looking. To determine whether Micron can reach a $1 trillion valuation, it's important to understand what's driving its price higher and whether those factors will sustain its growth well into the future.

What's behind Micron's soaring stock price?
Micron has been one of the biggest beneficiaries of the growing demand for high bandwidth memory (HBM). These memory chips are packaged with graphics processing units (GPUs) and AI accelerators for AI training and inference. With the growing demand for compute from AI developers, hyperscalers have increased their chip budgets, which, in turn, has increased demand for Micron's HBM.
The entire industry now faces a shortage of DRAM memory chips. These not only compose the building blocks of the high-bandwidth memory chips Micron makes but are also key components in other computing hardware, including PCs and smartphones.
As a result of the shortage, Micron has seen the prices it can charge for its chips rise considerably. The company's average selling price for DRAM chips increased 20% sequentially in the first quarter and gross margin expanded to 57% from 46%. With the pricing tailwind, Micron's earnings per share grew 167% to $4.78 last quarter and operating cash flow ballooned to $8.4 billion.
The company's outlook suggests 2026 could be even better. Management guided gross margin to expand to 68% this quarter, and earnings per share will reach $8.42. Management also said the supply of memory chips will remain tight beyond the 2026 calendar year.
That news kicked off another run in Micron's stock price, and analysts increased their expectations for fiscal 2026 and 2027 earnings. Wall Street now sees Micron generating $33.73 per share for 2026 and $43.54 in 2027.

Key Data Points
Can Micron climb to $1 trillion?
Micron stock trades at about 12.2 times analysts' 2026 earnings expectations and 9.4 times 2027 earnings expectations. That might seem cheap, compared to other AI semiconductor stocks, but Micron's business isn't as differentiated as those of high-end chipmakers.
Memory chips are practically a commodity, and Micron faces competition from Korean companies SK Hynix and Samsung. Rest assured, neither of them is sitting on the opportunity to ramp up DRAM chip production.
While all three have remained cautious about how long demand will remain elevated, all three major DRAM chipmakers are investing in production capacity. Micron itself plans to spend $20 billion in capital expenditures for fiscal 2026.
This cycle has played out repeatedly in the industry, leading to peaks and valleys in Micron's earnings. The three chipmakers have to ramp up capacity to meet demand, but they're left with an oversupply when demand slows, leading to severe declines in earnings power. The cyclical nature of the industry is why Micron's earnings today aren't valued as highly as a company with more predictable and sustainable earnings power.
Nonetheless, Micron's current earnings multiple is much higher than it has been amid other peaks in its earnings cycles over the last 15 years or so. Micron's trailing price-to-earnings ratio (P/E) around the peak of prior earnings cycles has ranged from 3 to 6.

As mentioned, Micron stock currently trades at 9.4 times 2027 earnings. That means investors are currently expecting the pricing tailwinds supporting Micron's current earnings boost to continue well past fiscal 2027. While AI demand is a strong driving force, past demand cycles suggest that Micron's earnings won't continue to climb much higher beyond 2027.
Even if this demand cycle extends to the end of the decade, the stock price is, at best, fairly valued. For it to reach a $1 trillion valuation, it would require overwhelming outperformance of management's guidance and analysts' expectations, fueled by an acceleration in demand from its hyperscaler end customers.
