The opening round of NASCAR's new Summer Series delivered a surge of interest, with the TNT broadcast attracting 2.2 million viewers and the concurrent CW slot pulling 1.145 million. Those numbers mark the highest audience for a Sonoma race since the track's debut in 2023, underscoring the series' expanding footprint.
Shane Van Gisbergen, the New Zealand‑born star, captured both the TNT and CW events, adding to his already impressive résumé. The victories bring his career total to 14 wins, eight of which have come in the Cup Series, cementing his status as one of the most successful road‑course racers in recent memory.

The races were aired under the umbrella of Turner Sports, with additional distribution on Prime Video and The CW. The collaboration reflects a strategic push to broaden NASCAR's digital reach, leveraging multiple platforms to capture a wider audience across the United States.
The Sonoma weekend also featured a peak viewing window of 1,231,000 viewers between 6:45 pm and 7:00 pm Eastern, contributing to an 18 percent year‑over‑year increase in total audience. This marks the 19th consecutive race that has drawn more than one million total viewers, a streak that highlights the sport's resilient popularity.
Beyond the numbers, the event showcased the growing synergy between traditional broadcast partners and emerging streaming services. As NASCAR continues to experiment with its schedule, the Summer Series is poised to become a staple of the sport's calendar, offering fans a fresh mix of road‑course and short‑track action.
