Niteharts Festival is coming back to Snapdragon Stadium in San Diego on October 9, 10, and 11, 2026, and this time it will stretch to three days. The expanded run gives the hometown return of Knock2 and ISOxo a bigger frame, with the pair set for a festival built around one stage and no set conflicts.
That is the reason fans are searching now: the lineup is out, the dates are fixed, and the ticket plan is already in motion. 2Hollis and RL Grime are headliners, Porter Robinson is booked for a DJ Set, and the supporting bill also includes Frost Children, Devault, LYNY, Thaiboy Digital & SWEDM, Nitepunk, and Hamdi. For a festival that leans hard into EDM and hyperpop, the draw is not just the names but the shape of the weekend, with every set feeding into the same stage instead of forcing choices.
Knock2’s return matters because it comes with one of the year’s few ISOKNOCK sets, while ISOxo is also slated for an H.C.D. set and Knock2 for a B2B with DJ Snake. That mix turns the 2026 edition into more than a simple repeat of the 2025 debut. It is a tighter, larger booking built around artists who have already helped define the festival’s identity.
Still, the way tickets went shows how fast demand got ahead of the announcement. Three-day passes sold out near-instantaneously in February, months before the lineup was revealed, leaving limited single-day tickets as the only public route in. Niteharts has paired with Ticketmaster for an official resale platform for sold-out three-day passes, so anyone who missed out on the full run will have to watch both that channel and the festival website.
Limited single-day tickets go on sale Friday August 7 at 10AM PST, and that is the next real test of how much appetite is left after the three-day allotment vanished in February. If the first wave already disappeared before fans knew who was playing, the remaining inventory is likely to be brief as well.
