Micron Technology Joins the Trillion Dollar Club as AI Demand Surges

The AI Boom Has Created Another Trillion Dollar Tech Giant
Micron Technology has crossed $1 trillion in market capitalisation for the first time, pushing it into the ranks of the world’s most valuable companies and placing it around 12th globally. The speed of the rise has been remarkable: the stock surged 19% in a single trading session on 26 May and has climbed roughly 700% over the past year. Just two months ago, Micron was valued at slightly above $500 billion. The company is part of the semiconductor industry, the chipmakers powering the global AI boom and now the market’s dominant growth story. Semiconductor and semiconductor equipment stocks now make up a record roughly 18% of the S&P 500’s total market value, the highest share ever held by a single industry group. A decade ago, that weighting was only about 2%, showing just how dramatically AI has reshaped where global investment capital is flowing.

So what does Micron Technology actually make? Memory chips. Every computer, smartphone, and data centre depends on two types of chips working together: processors and memory chips that store and move data. Micron specialises in the memory side, and right now demand is far exceeding supply. The AI boom has created massive demand for a specialised ultra fast memory known as high bandwidth memory (HBM), which sits alongside AI processors and feeds them data at extremely high speeds. Demand has become so intense that Micron’s entire HBM production is already sold out through 2026. When supply is scarce and demand keeps rising, prices and profits usually climb as well. A major upgrade from investment bank UBS, which nearly tripled its price target for the stock, helped push Micron over the trillion dollar mark.
