What Happened?
Shares of memory chips maker Micron (NASDAQ: MU) jumped 16.8% in the morning session after UBS analyst Timothy Arcuri tripled his price target to $1,625 from $535, sending the stock past the $1 trillion valuation mark for the first time and making it the most bullish call on Wall Street.
Arcuri's note re-framed Micron as an "AI-native infrastructure giant" rather than a cyclical memory maker, arguing that long-term supply agreements which already covered 60–70% of industry server DDR5 volumes gave the business Nvidia-like earnings visibility through 2029. UBS modeled EPS of $155, $167 and $117 for calendar 2027–29 (up from $133/$122/$77) and over $400 billion in cumulative free cash flow over the period.
The new target is based on a ~15x NTM multiple, with Arcuri writing he sees "no reason why MU should trade a whole lot differently than NVDA." CEO Sanjay Mehrotra called memory supply "structural scarcity," with Micron able to fulfil only 50–67% of HBM and DRAM demand.

What Is The Market Telling Us
Micron’s shares are extremely volatile and have had 48 moves greater than 5% over the last year. But moves this big are rare even for Micron and indicate this news significantly impacted the market’s perception of the business.
The previous big move we wrote about was 5 days ago when the stock gained 2.3% after AI chip leader Nvidia reported record sales and income, driven by what its CEO described as 'parabolic' demand for AI infrastructure.
The strong results confirmed investors' belief in a sustained AI-driven boom, lifting the entire semiconductor sector. Nvidia's success signals a massive buildout of data centers, which require a vast supply of high-performance chips.
This directly benefits memory chip manufacturers like Samsung and SK Hynix, which produce essential components like High Bandwidth Memory (HBM). The intense demand led some analysts to declare a 'semiconductor supercycle,' a prolonged period of above-average growth for the industry, as companies worldwide race to develop their AI capabilities.
Micron is up 178% since the beginning of the year, and at $876 per share, has set a new 52-week high. Investors who bought $1,000 worth of Micron’s shares 5 years ago would now be looking at an investment worth $10,652.
