TheGrant Park 165 was an annualNASCAR Cup Series race held on theChicago Street Course, astreet circuit inGrant Park,Chicago,Illinois,United States. The race was first held in2023 and was the first ever street race contested in the NASCAR Cup Series. TheNASCAR Xfinity Series alsoheld a race on the street course on the day before the Cup Series race.[2]
Shane van Gisbergen is the final winner of the race.
On March 24, 2021, NASCAR announced that an imaginary street course in theChicago Loop in Downtown Chicago would be the track for the fifth (and what turned out to be the final) race of the2021 eNASCAR iRacing Pro Invitational Series. The iRacing event was broadcast live onNASCAR on Fox on Wednesday, June 2.[3]Rick Ware Racing Cup Series driverJames Davison would win the virtual Chicago street race.[4] Ever since the announcement of the track's virtual creation for this iRacing event, there had been rumors and speculation that NASCAR would like to make this track a reality and have a street race in Chicago on the Cup Series schedule in the future. On July 7, 2022, Jordan Bianchi fromThe Athletic reported that an official announcement of a Chicago street race being added to the Cup Series schedule would come on July 19.[5] On June 17, Adam Stern fromSports Business Journal suggested that the Chicago Street Course could replaceRoad America on the 2023 Cup Series schedule as any street course race would likely replace one of the road course races and Road America did not have a contract to have a Cup Series race in 2023.[6] On July 19, the official announcement of the addition of the Chicago street race to the Cup Series schedule took place.[2] After the announcement, NASCAR executiveBen Kennedy confirmed Stern's report of the Chicago street race replacingthe race at Road America on the Cup Series schedule in a question and answer session with the media.[7]
On March 7, 2023, NASCAR announced that the race would not have a title sponsor and would instead be named afterGrant Park, which the street course will pass by. Similarly, the Xfinity Series Chicago street race was named The Loop 121 after theChicago Loop, the area of the city in which the street course is located. It was also announced on that day that the Cup Series race would be 220 miles and 100 laps in length.[1]
The inaugural running of the event was held during a rain storm. The start of the race was delayed, and eventually ran for only 78 of the scheduled laps. New Zealand racing driverShane van Gisbergen and triple AustralianSupercars champion won the event.[8] in his first-ever NASCAR race running forTrackhouse Racing's PROJECT91 program after qualifying in third.[9] He also became the first driver to win in his Cup Series debut sinceJohnny Rutherford in1963. Following the race win, van Gisbergen left Supercars in 2024 and came to the United States to race full-time in NASCAR. He later would join the Cup Series full time in2025.
On October 20, 2023, NASCAR announced that the Cup Series would be shortened from 220 miles (354.056 km) and 100 laps to 165 miles (265.542) and 75 laps.[10] This is a bit shorter than the length of the rain and darkness-shortened 2023 race, which was 171.6 miles and 78 laps long.
On July 18, 2025, officials of the race would announce that it would not return in 2026, with a potential to return in 2027.[11][12]
