The Chicago Fire's home venue will be known as SeatGeek Stadium as of next season.
SeatGeek and the Village of Bridgeview, which owns the stadium, announced on Thursday that the secondary market ticket seller has taken over the naming rights to Toyota Park.
Toyota bought the naming rights when the stadium opened in 2006, and Bridgeview retained the name even after the car manufacturer chose not to renew its deal in 2016.
The stadium has plunged Bridgeview deeply into debt, according to Bloomberg, which estimated the value of the deal at between $2.5 and $4 million per year.
"We're thrilled to align ourselves with SeatGeek as our new naming rights partner," Bridgeview mayor Steven Landek said in a statement. "We're excited about SeatGeek making a meaningful and long-term investment in the stadium and our community."
The naming rights deal is the first for SeatGeek, a nine-year-old company which also has partnerships with five other MLS clubs.
The statement announcing the deal also said SeatGeek would work with Bridgeview and venue managers Spectra to bring more concerts and "international sporting events" to the stadium, which is also the home of the NWSL's Chicago Red Stars.
