Chicago White Sox Ballpark Renamed to Rate Field

The name change reflects the stadium sponsor's rebranding and comes as the team explores relocating for a new stadium.

The Chicago White Sox officially announced that their home stadium will be renamed Rate Field starting in 2025, following the rebranding of sponsor Guaranteed Rate to Rate.
The ballpark, which opened in 1991 as Comiskey Park II, has previously been known as U.S. Cellular Field (2003-2016) and Guaranteed Rate Field (2016-2024).
Rate's 13-year naming rights agreement with the White Sox, signed in 2016, runs through 2029, with a team option for an extension.
Team owner Jerry Reinsdorf is actively seeking $1 billion in public funding for a proposed new stadium in Chicago's South Loop, though state officials have expressed reluctance to provide financial support.
The White Sox are coming off a historically poor 2024 season, finishing with a record-breaking 121 losses, adding urgency to the team's efforts to revitalize its future both on and off the field.
