Micron to break ground on $100B New York semiconductor fab

For months, construction activity at a major New York semiconductor site moved in fits and starts.

Tech company Micron adjusted long-term timelines in November 2025 for when its first fab would begin operations, pushing the date back by two to three years. But even as those dates shifted, early site work quietly progressed in the background.

Providence, Rhode Island-based builder Gilbane won a preconstruction contract in August to prepare the ground for the site. The award marked the first phase of development at the White Pine Commerce Park site.

Next week, the project reaches a more visible milestone.

Micron announced it will officially break ground Jan. 16 on its $100 billion megafab in Onondaga County, New York, according to a Jan. 7 news release. The company received the greenlight to proceed after obtaining “rigorous environmental review and necessary permit approvals,” per the release.

The company said this project marks the largest private investment in New York state history.

Once complete, the campus, which could feature up to four fabs, will house the most advanced memory manufacturing facility in the world, according to Micron. The $100 billion investment will help the tech company meet the growing demands of the artificial intelligence boom, the company added.

“Breaking ground at Micron’s New York megafab is a pivotal moment for Micron and the United States,” said Sanjay Mehrotra, chairman, president and CEO of Micron Technology. “As the global economy enters the AI era, leadership in advanced semiconductors will be the cornerstone in innovation and economic prosperity.”

Officials from the Trump administration, Congress and New York state and local government will join Mehrotra during the groundbreaking ceremony next week, according to Micron.
