‘America’s Got Talent’ Season 21 Episode 20 Release Date, Time, Where to Watch and What to Expect
The competition on ‘America’s Got Talent’ is heating up fast, and Season 21 is barreling toward one of its most pivotal nights yet. The live shows kicked off on August 18 on NBC, with Quarterfinals running through September 8, followed by Semifinals on September 15 and 16, and the Finals and Finale airing September 22 and 23.
For anyone trying to keep track of exactly when to tune in, how the voting works now, and which acts are still standing, this is the moment the season truly narrows down. With the judges’ power officially handed over to viewers, the next episode carries real weight for the Top 44 hopefuls fighting for a spot in the finale.
‘America’s Got Talent’ Season 21 Semifinals Release Date and Time
The Live Semifinal Performances are scheduled for Tuesday, September 15 at 8 p.m. ET, with the Live Semifinal Results following the next night, Wednesday, September 16, also at 8 p.m. ET. That two night format has become the standard rhythm for ‘America’s Got Talent’ this season, giving one night for performances and a separate night dedicated entirely to who moves forward.
This comes right after the September 8 Quarterfinal episode, which aired as a special three hour live event featuring immediate voting and instant results, with no new episode airing the following day. That scheduling shake up happened because of NBC’s football coverage, but it also means the show condensed an entire week’s worth of drama into a single marathon broadcast before heading into the Semifinals.
Once the Semifinals wrap, there is only one round left. The Live Finals are set for Tuesday, September 22, followed by the Live Finale on Wednesday, September 23. That is when ‘America’s Got Talent’ will crown its Season 21 winner.
Where to Watch ‘America’s Got Talent’ Season 21?
Fans can catch new episodes of ‘America’s Got Talent’ Tuesdays at 8/7c on NBC, with episodes streaming the next day on Peacock. For the Semifinals specifically, that means the performance episode airs live on NBC before becoming available to stream on Peacock, while the results episode follows the same pattern on Wednesday.
Voting for this round works a little differently than in past seasons, since audiences now have control over which acts advance rather than the judges making saves or granting wild cards. Viewers can vote through the NBC website, the AGT app, or by commenting on the show’s TikTok posts, with up to ten votes allowed per method before voting closes each Wednesday morning at 7 a.m. ET.
That expanded voting window, especially the addition of TikTok comments as an official method, has become one of the more talked about format changes of the season among longtime fans of the show.
What to Expect From the Season 21 Live Shows?
In the Semifinals, twelve acts will perform, and America will vote to advance six of them into the Finals, joining the acts who already secured their spots through the Live Golden Buzzer. On top of the public vote, the judges will hit a collective Golden Buzzer for one additional Semifinalist, pushing the total number of acts moving on to the Finals into double digits.
This season has also leaned heavily on the Golden Buzzer as a competitive tool. This retains its Live Golden Buzzer format, but has removed Wild Cards, Saves, and other judge driven advancements, putting the audience fully in charge of who continues in the competition. That shift has raised the stakes for every performance, since there is no safety net if a judge personally loves an act but the public vote does not go their way.
The road to this point has not been entirely smooth for the judging panel either. Simon Cowell has been absent from the live judging panel for a few weeks while recovering from back surgery, with guest judges stepping in during his time away. Kenan Thompson filled in for the third Quarterfinal round, while Heidi Klum returned as a guest judge for the final Quarterfinal round.
Top 44 Acts and the Path to the Finale
The Top 44 Acts advancing to the Live Quarterfinals featured a mix of singers, dancers, comedians, magicians, stunt performers, viral newcomers, and established entertainers hand selected by the judges. That variety has been on full display throughout the Quarterfinal rounds, and it sets up a genuinely unpredictable Semifinal night since so many different kinds of talent are still in the running.
By the time voters get to the Finals, the field will be considerably smaller. The Finals of Season 21 are set to take place at the Pasadena Civic Auditorium, with a total of ten acts competing for the one million dollar prize. Getting to that stage means surviving both the judges’ scrutiny in earlier rounds and now the unpredictable nature of a fully audience driven vote.
Terry Crews remains at the helm as host, continuing to guide contestants and viewers through what has already been a season full of format changes and scheduling curveballs. Between the compressed Quarterfinal finale, the rotating guest judges, and the new TikTok voting option, Season 21 has given fans plenty to react to well before the Semifinals even begin.
With the Semifinal performances airing September 15 and results following the next night, the pressure is squarely on the twelve remaining acts to make an impression that lasts. Which act do you think has the best shot at winning America’s vote and locking in a spot in the ‘America’s Got Talent’ Season 21 finale?
