Gainbridge Fieldhouse is an indoor arena located in downtown Indianapolis, Indiana. It opened in November 1999 to replace Market Square Arena. The arena is the home of the Indiana Pacers of the National Basketball Association and the Indiana Fever of the Women's National Basketball Association. The fieldhouse also hosts college basketball games (including the annual Big Ten Conference tournaments), indoor concerts, and ice hockey.
The arena was originally named Conseco Fieldhouse, as the naming rights to the venue were sold to Conseco, a financial services organization based in nearby Carmel. In May 2010, the company renamed itself as CNO Financial Group, but the fieldhouse retained the Conseco name. In December 2011, CNO Financial Group changed the name of the fieldhouse to Bankers Life Fieldhouse, after one of its subsidiaries, Bankers Life and Casualty. CNO decided not to renew its naming sponsorship after it expired on June 30, 2019. On September 27, 2021, the fieldhouse announced that Indianapolis-based financial platform Gainbridge would be the new naming partner for the fieldhouse in a multi-year partnership.
In April 2019, the Marion County Capital Improvement Board approved a major renovation project for the fieldhouse. The $360 million project will include a new outdoor entry plaza, new indoor gathering areas, and various interior enhancements. The Pacers committed to remaining in Indianapolis for at least 25 more years as part of the renovation agreement. Construction will take place in two phases, with the fieldhouse having planned to host the 2021 NBA All-Star Game in between the phases, which was later canceled due to the COVID-19 pandemic. Almost all of the construction work will take place during Pacers offseasons. The project will displace the Fever for all of the 2020 and 2021 WNBA seasons, as well as at least part of the 2022 season; the Fever played the first section of the schedule at Gainbridge Fieldhouse, but after the NBA season ended, the Fever played games at Indiana Farmers Coliseum.
The arena was built to evoke an Indiana high school and college field house. As such, unlike most other North American sports arenas, it was designed primarily for basketball. The arena can accommodate an NHL-sized rink, but the ice hockey seating capacity is reduced to 12,300 in an asymmetrical configuration.
From 2002 to 2007, the fieldhouse served as the site of the Big Ten Conference men's basketball tournament in even-numbered years while the tournament was held at the United Center in Chicago in odd-numbered years. In 2008, the tournament was moved to Conseco Fieldhouse exclusively for five years, through 2012. The arena is also a frequent site of the Big Ten women's basketball tournament. 2012 marked the 12th time in 13 years that the tournament had been held at the fieldhouse. On June 5, 2011, the Big Ten Conference announced that beginning in 2013 the location of both of the conference basketball tournaments for the following four years would be alternated between the Chicago area and Indianapolis. Bankers Life Fieldhouse would again be the site for both men's and women's events in 2014 and 2016. The 2011 NCAA Women's Final Four was also held at the fieldhouse on April 3 and April 5 of 2011. For basketball, the venue seats 17,923 (18,345 from 1999 to 2006, 18,165 from 2006 to 2016).
From 2011 to 2021 the fieldhouse hosted the Crossroads Classic, an annual event that included the Butler Bulldogs, Indiana Hoosiers, Notre Dame Fighting Irish, and Purdue Boilermakers men's basketball teams.
