Gran Hermano 2026, a reality television show marking its 25th anniversary, will officially begin on February 23, 2026, at 22:15. The production is introducing participants in two phases, with some entering on the premiere night and others on February 24. Fans eagerly anticipated the first gala on February 22, but they will have to wait until the following week for the next live event.

Santiago del Moro, the show's host, has teased some of the changes that will be present in this edition of Gran Hermano. Among the expected modifications are new rules and a game format that aims to be more dynamic compared to past seasons. This modernization reflects both viewer demands for innovation and the show's commitment to staying relevant in an evolving media landscape.

One notable change includes the scheduling of the first nomination gala, which is set for February 25, just two days after the start of the show. This quick turnaround is designed to ramp up the competitive intensity early in the season, suggesting a shift toward a more engaging experience for viewers, which could potentially attract a wider audience and sustain interest throughout the season.
