Heidi Klum's primetime musical event, "HeidiFest," is transitioning from ProSieben to RTL and RTL+. This move follows low viewership for the program on ProSieben during 2025. The live event is scheduled to take place at the Hofbräuhaus in Munich on September 17, 2026.

The network shift follows a 2025 premiere that failed to capture a significant share of the key 14-to-49-year-old demographic, achieving only a 5.9 percent market share. Consequently, ProSieben has decided not to broadcast another live version of the event. 

While RTL has secured the rights to broadcast the Oktoberfest gala from the Munich Hofbräuhaus starting in 2026, the transition has sparked speculation regarding whether Klum's other major production, "Germany's Next Topmodel" (GNTM), will also move to RTL. RTL has not confirmed or denied these plans, stating their current focus is on the upcoming "HeidiFest" and that further details will be shared when available.
