Micron raises its US capex commitment to $250B through 2035, adding $50B for New York, Idaho, Virginia, and other projects, and invests $500M in GlobalWafers
Micron Technology Inc. plans to increase its spending on new plants in the US to $250 billion to help meet unprecedented demand …

Context & Ripple Effects
Micron’s US expansion has progressed from a $40B-by-2030 plan, including an Idaho memory fab, to a CHIPS Act-backed New York and Idaho buildout that had been described as up to $125B over a longer horizon. The new commitment substantially extends that domestic manufacturing arc.
The increase follows a sharp revenue upswing and higher 2026 capex expectations, while Micron is also expanding in Hiroshima and targeting HBM shipments from 2028. Its $500M investment in GlobalWafers ties the buildout to a key upstream wafer supplier.
First-order effects
Micron commits an additional $50B to US projects through 2035, increasing the scale and duration of planned construction and equipment spending across New York, Idaho, Virginia and other sites.
GlobalWafers gains a direct $500M investment from a major memory-chip customer, strengthening its connection to Micron’s planned capacity ramp.
Second-order effects
The enlarged program raises demand visibility for the US semiconductor construction, fab-equipment and wafer supply chain, while increasing the execution pressure on Micron to bring capacity online in step with demand.
Other memory producers face a clearer signal that Micron intends to expand both US manufacturing and HBM supply; this could intensify competition for production inputs and skilled fab labor as capacity plans overlap.
Third-order effects
If these commitments translate into operating fabs, US memory-chip production would become less concentrated in existing overseas manufacturing hubs, though the outcome still depends on project delivery and sustained demand.
The move reinforces a model in which government-supported domestic manufacturing programs and private supplier partnerships shape where advanced semiconductor capacity is built.
The trend: AI-linked memory demand is accelerating a broader shift toward geographically diversified, policy-supported semiconductor capacity and more tightly aligned supply chains.
Today in Central New York, I joined @HowardLutnick as @MicronTech announced it is growing its U.S. investment to $250 BILLION in America's semiconductor supply chain - building on the commitment secured by @POTUS last year. Micron is moving at Trump speed to build a megafab, the …

Today is a proud day for Micron and American manufacturing. 🇺🇸 We're increasing our planned U.S. manufacturing and R&D investment commitment to more than $250B, supporting our goal of producing 40% of our DRAM in America and creating 90,000+ jobs. We also poured the first [image]
Today, @SBA_Kelly joined @HowardLutnick at the Micron concrete pouring ceremony in Central New York - where the company announced an increased $250 BILLION nationwide investment in the domestic semiconductor supply chain. President Trump's fair trade agenda is working: bringing […
Today in Clay, New York, @MicronTech poured the first concrete for its historic semiconductor campus. After announcing a $250 billion investment in America under President Trump, construction is now underway on one of the largest semiconductor manufacturing projects in U.S. [imag…
Today marks a major milestone for Micron as we celebrate the first concrete pour at our Clay, New York fab and increase our planned U.S. investments to more than $250 billion through 2035. This investment will help advance our goal of producing 40% of Micron's DRAM in the U.S. [i…
Thanks to @POTUS' tariff program, semiconductor manufacturing is roaring back, with Apple, Broadcom, and Micron investing billions of dollars to produce advanced memory chips on American soil. [video]
Tim Cook has done more to curb inflation than any President All he had to do was raise prices and now Micron is emptying their wallets Why $aapl is at all time highs along with semiconductor companies [image]
