Overview The Sports Illustrated Circuit Series is the late-night party Sports Illustrated throws on Formula 1 race weekends, a bill that has carried The Chainsmokers, Travis Scott, Post Malone, The Kid LAROI and Dom Dolla. In 2021 it was the official after party of the US Grand Prix weekend in Austin, and in 2023 it went to Montreal, the first time Sports Illustrated's events business had entered Canada. For 2026 Authentic Live, the events arm of Authentic Brands Group, which owns the brand, scheduled it for Miami, Montreal, Austin, Las Vegas and, for the first time, Singapore. In Austin and Las Vegas it runs alongside Club SI, the magazine's trackside hospitality suite at the same races. On site Each stop is a single night in a different kind of room. The 2021 Austin party, co-produced with The h.wood Group's Bootsy Bellows, was built at the Austin American-Statesman site. Montreal in 2023 took a 44th-floor terrace downtown: VIP and media from 7 p.m., then invited guests and hospitality-package holders from 10 p.m. to 2 a.m. Austin in 2025 opened at 9 p.m. on East Third Street and ran into the early morning. In Miami in 2026 it moved to the Guitar Hotel pool at Seminole Hard Rock Hollywood. Every stop has a live headline set, general admission and VIP tables. Talent and Influencers The Chainsmokers, Travis Scott, Chase B and DJ Irie played Austin in 2021, to a room that included Serena Williams, Alexis Ohanian, Winnie Harlow and Logan Paul. Chantel Jeffries DJed and snowboarder Mark McMorris hosted Montreal in 2023. SOFI TUKKER and Xandra Pohl headlined Austin in 2025, with Adrian Grenier, Brooks Nader, Camille Kostek, Chase Rice and Tara and Hunter Woodhall in the crowd. Shaquille O'Neal, as DJ Diesel, and Loud Luxury played Miami in 2026. Track record Authentic puts the Austin, Las Vegas, Montreal and Miami editions from 2023 to 2025 at 289 million social impressions and $133 million in advertising value. Brand presence Partners come in at four levels: a presenting partner with presenting rights, a custom activation and VIP and general-admission tickets; participating partners with their own activation; hospitality buyers on VIP tables; and print and digital media programs with Sports Illustrated. At Austin in 2025 Patron, Grey Goose and Celsius poured, Champion dressed the night and Verizon ran connectivity.
