ARC Music Festival is a dance music festival in Chicago, and its 2026 edition took place in Union Park over Labor Day Weekend. Its own line is "House comes home", and its official Facebook page says it brings the global scene to the birthplace of house music. The 2026 edition ran over four days, from Friday, September 4 to Monday, September 7, and the official passes page offered 4-day passes as well as a single-day pass for each day from Friday to Monday.
ARC's first edition was in 2021, and 2025 marked its five-year milestone. Looking back on the first four editions, the festival's own 2025 lineup post recalled Eric Prydz bringing all three of his aliases (Eric Prydz, Pryda and Cirez D) in 2021, Carl Cox and Green Velvet's B2B at the Expansions stage in 2024, and Hiroko Yamamura closing the 2023 weekend at Area 909. Past lineups back to 2021 are archived on the official site.
In 2026 the festival hours were 2pm to 10pm, general admission was 18+, the event was cash-free, and there was no camping: everyone left the park at the end of each night. The festival posted its 2026 set times as images on its set times page. We only list artists a festival names in text: its own Facebook post announcing ARC 2026 named Anyma, Beltran, Chris Stussy, Green Velvet, Josh Baker, Mau P and Michael Bibi "& many, many more", and its Instagram posts about the 2026 weekend also named Dennis Cruz and Ben Sterling.
