TLDR

• President Trump publicly called Micron “great” at a New York rally, boosting investor confidence
• MU stock climbed nearly 35% in five days, briefly pushing Micron above a $1 trillion market cap
• UBS raised its price target to $1,625 from $535
• Micron’s 2026 high-bandwidth memory supply is fully sold out, with HBM4 production already underway
• MU still trades at 8.42x forward earnings, well below the S&P 500 and Nasdaq 100

President Donald Trump praised Micron Technology at a New York rally, calling the company “great” and pointing to its plan to invest more than $100 billion in Clay, New York. The comments sent MU stock sharply higher.

Micron Technology, Inc., MU

MU climbed nearly 35% over five trading days following the remarks. The stock briefly pushed Micron’s market value above $1 trillion for the first time.

The rally built on existing momentum driven by strong AI memory demand. Micron had already been one of the better-performing chip names heading into the week.

Trump’s endorsement came as investors were already watching Micron closely. The company has become a key name in the AI hardware trade due to its high-bandwidth memory chips.

UBS added fuel to the fire, raising its price target on MU to $1,625 from $535. That kind of move from a major bank tends to get attention, and this was no exception.

Micron said its entire 2026 high-bandwidth memory supply is fully sold. That means every chip it plans to produce this year already has a buyer lined up.

The company is also moving ahead with next-generation HBM4 production. That puts Micron in a strong position as the AI buildout continues to demand more and faster memory.

Valuation Still Looks Cheap Relative to Peers

Despite the sharp run-up, MU still trades at 8.42 times expected earnings over the next 12 months. That is well below the broader S&P 500 and Nasdaq 100 by comparison.

That gap has kept bulls engaged. The argument is straightforward: if AI spending holds up, Micron’s earnings could grow fast enough to justify even higher prices.

The $1 trillion milestone was brief but symbolic. It puts Micron in a club that few chip companies have entered, and it came faster than most analysts expected.

Trump’s Comments Come at a Pivotal Moment

Trump’s remarks were not part of a formal policy announcement. They came during a rally, which made them informal but no less powerful in terms of market impact.

Investors have been watching Washington closely for any signals on semiconductor policy. Any presidential nod toward a domestic chipmaker carries weight given the ongoing focus on supply chain and national security.

Micron’s Clay, New York facility is a large-scale domestic investment. The $100 billion figure Trump referenced is one of the bigger manufacturing commitments in recent memory for the chip sector.

The stock’s reaction showed just how sensitive MU has become to any news that reinforces the AI memory demand story. Combine a presidential shoutout with a sold-out order book and a massive UBS target hike, and the move starts to make sense.

UBS’s revised target of $1,625 implies further upside from current levels. Whether Micron can sustain the momentum will depend on whether that AI demand story continues to hold.
