Race context and quick facts
- This race marks the opening event of the 2026 Cup Series Chase (the 10-race postseason for the series), with 16 drivers competing for the championship over the coming weeks.
- The Southern 500 is a long-standing Labor Day weekend fixture at Darlington Raceway; the 2026 running is commonly reported as a roughly 501-mile endurance test on the historic, 1.366-mile egg-shaped oval.
- Pre-race reporting noted that Saturday’s practice and qualifying sessions were impacted by weather in some reports; starting lineups in such situations can be set according to NASCAR rule-book procedures if qualifying is canceled. One outlet states Tyler Reddick will start from the pole after qualifying was affected by weather.
What we verified and outstanding details
Multiple U.S.-based sports and news outlets, as well as NASCAR’s official coverage notes, consistently report the 5:00 p.m. ET start time, USA Network as the TV broadcaster and HBO Max as the streaming partner. Radio coverage on MRN and SiriusXM NASCAR Radio is likewise confirmed across sources.
Some timing details — such as the precise moment the green flag will fall (widely reported as shortly after 5:00 p.m., for example around 5:10 p.m.) — are presented as expectations in the coverage rather than guaranteed clock times; local delays, weather or on-track incidents can push the green flag later. If qualifying or practice were canceled in your timing window, consult NASCAR’s official channels for any adjustments to the starting order.
