Niteharts Festival is expanding to a 3-day return at Snapdragon Stadium in San Diego on October 9, 10, and 11, 2026, with Knock2 at the center of the bill. The move gives the festival a larger frame after its 2025 debut, but the immediate takeaway for readers is narrower: 3-day passes are already gone, and the remaining access is limited.
Knock2 and ISOxo returned to present the 2026 lineup after the 2024 San Diego 4EVR shows and the 2025 debut of Niteharts Festival. The two are also tied to the live draw here, with Knock2 set for a B2B set with DJ Snake and ISOxo scheduled for an H.C.D. set, while 2Hollis and RL Grime headline the festival.

The lineup leans into EDM and Hyperpop and keeps the event on one stage, which means the schedule stays tightly managed instead of spreading across multiple performance areas. Porter Robinson is set for a DJ Set, and the supporting lineup includes Frost Children, Devault, LYNY, Thaiboy Digital, SWEDM, Nitepunk, and Hamdi. For a festival with a single-stage format, that kind of bill is less about overlap and more about timing the strongest names into one run.
Ticketmaster resale rules
3-day passes sold out near-instantaneously in February before the lineup announcement, a rare sequence that shows how far the brand had already moved on reputation alone. Niteharts partnered with Ticketmaster to provide an official resale platform, so the only path left for many buyers is the secondary market rather than a fresh 3-day release.
August 7 at 10AM PST
Limited single-day tickets go on sale Friday August 7 at 10AM PST on the Niteharts website, and that is the practical next step for anyone still trying to get in. With the full 3-day run already spoken for, the real story now is how quickly those remaining single-day tickets move once the sale opens.
