NASCAR arrived at the Chicago Street Course for the 2025 Grant Park 165, and the drama was high as always. Michael McDowell and Ryan Blaney won the first two stages; however, neither driver was upfront at the end. Instead, a Trackhouse Racing driver from New Zealand returned to victory lane in Chicago.

At the end of the day, Shane van Gisbergen won his second Cup Series race of 2025 at the Chicago Street Course. After a slight overview of the notable moments, here are the NASCAR TV ratings following the 2025 Grant Park 165 at the Chicago Street Course.

NASCAR and Warner Bros. Discovery earned 2.1 million average viewers for the Grant Park 165 at the Chicago Street Course on TNT. Compared to the 2024 event, Chicago was down from 1.8 million average viewers. Overall, it was a shocking TV turnout for NASCAR and Warner Bros. Discovery on Sunday afternoon.

Now, NASCAR will focus its attention on Sonoma Raceway, as the 22nd NASCAR race weekend will be underway in just a few days.
