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 buildout has expanded repeatedly: from a $40B domestic-manufacturing plan in 2022 to projects centered on Idaho and New York, then to a CHIPS Act award supporting an up-to-$125B New York and Idaho program in 2024.
The larger commitment follows a sharp revenue upswing and a higher 2026 capex outlook, while Micron is also expanding in Hiroshima and targeting HBM shipments from 2028. The GlobalWafers investment ties the manufacturing push to a critical upstream materials supplier.
First-order effects
Micron commits an additional $50B to US projects through 2035, increasing the scale and duration of planned spending across New York, Idaho, Virginia, and other sites.
GlobalWafers receives a $500M investment, giving Micron a more direct stake in securing wafer supply alongside its capacity expansion.
Second-order effects
The enlarged buildout raises the execution burden on US semiconductor construction, equipment, materials, and labor ecosystems, while increasing the importance of reliable wafer availability for Micron’s ramp.
Other memory producers and US-based semiconductor supply-chain players face a stronger incentive to secure capacity, inputs, and public-sector support as Micron extends its domestic footprint.
Third-order effects
If these projects progress as planned, US memory manufacturing would become less dependent on a small set of overseas production hubs, though the outcome depends on whether suppliers and workforce capacity scale with fab investment.
The move reinforces an industrial-policy model in which public incentives help catalyze long-lived private chip investment, and in which chipmakers increasingly manage supply-chain risk through direct supplier partnerships.
The trend: AI-driven memory demand is accelerating a shift from cyclical fab spending toward geographically diversified, supply-chain-integrated semiconductor capacity plans.
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 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…
Micron $MU is the most mispriced stock in the S&P 500 right now: > You rarely see a combination of high revenue growth + low valuations in the S&P 500. > Micron has ~250% revenue growth for current year (fastest growth in the index). > Micron is one of the cheapest stocks on a [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]
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 […
