The automobile manufacturer behind Chrysler, Jeep, Ram and Fiat will invest $13B into its factories over the next four years to ramp up its U.S. vehicle production by 50%.

Stellantis' investment will support the debut of five new vehicles and create more than 5,000 jobs at production sites in Illinois, Indiana, Ohio and Michigan. Stellantis CEO Antonio Filosa said the investment is the largest in the company's 100-year U.S. history.

“Accelerating growth in the U.S. has been a top priority since my first day,” Filosa said in a statement. “Success in America is not just good for Stellantis in the U.S. — it makes us stronger everywhere.”

The company shipped around 1.3 million vehicles during the third quarter. That total was a 13% year-over-year increase driven by strong numbers in North America.

The announcement comes after what Filosa described as “very productive talks” with the Trump administration, The New York Times reported. Companies like Apple and Pfizer have also announced huge U.S. investments while seeking tariff concessions from the administration.

The latter announced $70B in U.S. projects last month and then secured a “three-year grace period” from tariffs.

In the auto world, Hyundai, Tesla and Honda have announced similar U.S. manufacturing pushes.

President Donald Trump committed to revitalizing American manufacturing while also turning the country into the world's leader in artificial intelligence.

The world's largest tech companies could devote as much as $400B this year to data centers and chips, but U.S. manufacturing hasn’t seen the same growth.

“You have the software and services world accelerating, and becoming almost a monomania for the culture, at the same time that manufacturing remains flat or worse,” Brookings Institution senior fellow Mark Muro told The Washington Post. “The AI boom is kind of papering over some other parts of the economy that aren’t going well.”

Still, U.S. manufacturing momentum could be building. Apollo Global Management Chief Economist Torsten Slok said the U.S. has emerged as a key driver in the industrial revival.

The country has a $590B project pipeline headlined by multiple projects of more than $5B each. Slok told Seeking Alpha those projects could create long-term ripple effects for the nation’s economy.

One of those huge projects is now Stellantis’ planned investment.

The company plans to spend more than $600M to reopen the Belvidere Assembly Plant in Illinois, spend $400M at the Toledo Assembly Complex in Ohio, and conduct a $100M refresh of the Warren Truck Assembly Plant in Michigan to launch a new hybrid SUV.

Stellantis also confirmed previously announced investments. The Detroit Assembly Complex-Jefferson will get a $130M investment, and in Indiana, the company plans to spend more than $100M at its Kokomo facilities to produce a new four-cylinder engine.

Stellantis has 34 manufacturing facilities and employs more than 48,000 workers in the U.S.
