Micron hits $1 trillion market cap for the first time as stock surges 18%
Shares jump in early Tuesday trading, pushing the chipmaker’s valuation past the historic milestone while trading at a discount to broader market indices.

Micron Technology has reached a $1 trillion market capitalisation for the first time, following an 18% surge in its share price during early trading on Tuesday. The milestone comes after the company’s stock closed at $751 on Friday, with the sharp rally driven by a global memory shortage exacerbated by surging demand for artificial intelligence infrastructure.
The increased appetite for AI-related hardware has significantly spiked interest in chipmakers, with Micron at the forefront of the sector’s renewed momentum. Analysts note that this demand is fundamentally reshaping semiconductor valuations, prompting major financial institutions to adjust their outlooks. UBS, for instance, has tripled its price target for Micron, citing the structural shift in AI-driven demand as a key factor in the company’s revised trajectory.
Despite the massive valuation jump, Micron’s stock was trading at 8.42 times expected earnings over the next 12 months at the time of the surge. This multiple remains significantly lower than the broader market benchmarks, with the S&P 500 index trading at 21.1 times expected earnings and the Nasdaq 100 at 24.66 times. The disparity highlights the relative value investors are currently assigning to semiconductor hardware compared to the wider technology sector.
The market movement occurs against a backdrop of heightened geopolitical and corporate activity. A summit between US and Chinese leaders is currently underway in Beijing, attended by prominent US CEOs including Elon Musk, Tim Cook, and Jensen Huang, with trade, artificial intelligence, and regional security on the agenda. Concurrently, other major tech firms are seeing significant volatility; Amazon shares rose 31.9% in a month following strong fourth-quarter fiscal 2025 results, while Nvidia shares surged more than 2% following a chip sale approval.
The convergence of supply constraints and unprecedented AI investment has created a distinct environment for memory chipmakers. As institutions continue to weigh the long-term implications of AI infrastructure build-outs, Micron’s entry into the trillion-dollar club signals a pivotal moment for the semiconductor industry, reflecting both the scale of current demand and the market’s confidence in sustained growth.
