As anticipated, spoilers for Thunderbolts* have started to surface online after the film's global premiere in london earlier tonight. According to reports, the film included a sequence during and after the credits. We have a thorough analysis of the second, thanks to MTTSH, but details on the first are hazy (there are contradicting accounts, making it hard to determine which are authentic).

SPOILER ALERT!

Several social media responses referred to the post-credits scene as "insane" and a "game changing moment," which may be a bit of an exaggeration, but it does seem to directly relate to what happened in Avengers: Doomsday.
 
"The following is the Thunderbolts* post-credits scene: In their new tower, the New Avengers discuss Sam's hiring of his own New Avengers squad and his ownership of the name's copyright. Subsequently, they learn that the Fantastic Four ship is entering their universe from space. Pedro Pascal (Reed Richards) attended the premiere, but we don't know if the Fantastic Four themselves show there.


New box office projections indicate that Thunderbolts* will earn between $63 million and $77 million domestically during its opening weekend, and we have received confirmation that the next MCU film will have a pretty regular runtime of two hours and six minutes. 

Given that Thunderbolts* is a rather unknown film with no significant A-list stars (the biggest names are by far Florence Pugh and Sebastian Stan), this wouldn't be a bad outcome for a film with a (relatively) low budget of $180M (excluding additional costs).
 
During Marvel's last live-stream, it was confirmed that the film's primary cast—aside from Olga Kurylenko—would be returning for Avengers: Doomsday.
