Kevin Plank Net Worth

Kevin Plank has an estimated net worth of $1.1 billion, according to Forbes World's Billionaires List 2026, Kevin Plank profile (figures as of Forbes World's Billionaires List 2026). That is down from a peak of $2 billion.

Kevin Plank is an American businessman best known for founding Under Armour, the Baltimore company that sells sportswear, footwear, and accessories. The idea started when he noticed how soaked football shirts could get and looked for a lighter fabric that would pull sweat away from the body. After college, he tested prototypes, named the company Under Armour, and began selling shirts himself from his grandmother’s basement and from his car.

His rise came from turning that simple product idea into a major sportswear brand. A late 1999 ad in ESPN The Magazine helped bring in $1 million in direct sales the next year, giving the business a big push. Plank later took Under Armour public in 2005. Beyond the apparel company, he also built businesses through Plank Industries, including Sagamore Spirit, real estate projects in Baltimore, and a renovated hotel property in Fells Point.

How Kevin Plank built his fortune

Most of Kevin Plank’s wealth comes from Under Armour, the company he started in 1996. He built it around performance shirts designed to keep athletes drier than cotton. Early on, he leaned on football connections, sending shirts to former teammates and asking them to share the product in locker rooms. A first big team sale to Georgia Tech helped. By 2005, he had taken Under Armour public, turning a basement startup into a public company in Fashion & Retail.

Plank also expanded beyond apparel. Beginning in 2013, his real estate firm Sagamore Development led a $5.5-billion project in Baltimore’s Port Covington area. That same year, he founded the whiskey distillery Sagamore Spirit, with first bottles sold in 2016. He also renovated the former Recreation Pier building, which reopened as the Sagamore Pendry Hotel, and his wider business group bought and revamped the Inner Harbor water taxi. Those ventures added to a career built on consumer brands and property.

Forbes net worth over time

Forbes put Kevin Plank’s net worth at $1.1 billion on the World’s Billionaires List in 2026. The estimate tracks a founder whose money is closely tied to Under Armour and his other business holdings. He stepped down as Under Armour’s CEO in 2019 and returned to the role in 2024. Over time, his business activity also included digital fitness deals, whiskey, hospitality, transportation, and large Baltimore development projects, which help explain why his wealth has moved over different years.

The Forbes estimate has shifted several times: $1.9 billion in 2019, $1.1 billion in 2020, $2 billion in 2021, $1.5 billion in 2022, $1.1 billion in 2023, $1 billion in 2025, and back to $1.1 billion in 2026. Those changes line up with the ups and downs that can come with a founder’s stake in a public company. Under Armour remained the center of his fortune throughout, even as he built projects through Plank Industries.
