‘America’s Got Talent’ Season 21 Episode 21 Release Date, Time, Where to Watch

Fans of ‘America’s Got Talent’ are gearing up for one of the most emotional nights of the summer, as the countdown to the Season 21 Semifinal Results episode is officially underway. After weeks filled with Golden Buzzers, guest judges, and shocking Quarterfinal upsets, the competition has narrowed down to a dozen acts vying for six coveted spots in the Finale.

This results episode is particularly significant as it marks the last time America’s vote alone determines who advances before the season crowns its next champion. With the Golden Buzzer now retired for the remainder of the competition, every act’s fate rests solely on viewer support, making fans more invested than ever as they await the announcement.

The Semifinal Performances aired live on Tuesday, September 15, with the results episode set to follow immediately after, airing Wednesday, September 16 at 8 p.m. ET on NBC. This schedule has been confirmed as part of NBC’s rollout for the Live Semifinal Performances and the Live Semifinal Results, both airing at 8 p.m. ET.

The two-night format has become standard for ‘America’s Got Talent’ during its live rounds, allowing the show to showcase a full night of performances before dedicating a separate hour to results the following evening. Fans keeping track of when to tune in have noted that Season 21 is approaching one of its most crucial nights yet as the competition narrows down to its final stretch.

For those who missed the live broadcast, the wait for a rebroadcast is brief. The performance episode airs live on NBC before becoming available to stream, with the results episode following the same next-day pattern on Peacock.

Streaming access for ‘America’s Got Talent’ remains consistent with how the show has operated all season. New episodes air Tuesdays on NBC at 8 p.m. ET, with results shows following. Viewers can watch on NBC through local affiliates, cable, or live TV services, while streaming the next day episodes on Peacock.

This means fans who cannot catch the Wednesday night broadcast live will find the full Semifinal Results episode on Peacock starting Thursday. Season 21 episodes can also be streamed the next day through NBC.com and the NBC App in addition to Peacock.

Voting for this phase of the competition has also expanded beyond traditional methods. Fans can support their favorite acts through the AGT app, the NBC website, or by commenting directly on the show’s official TikTok voting posts, a new option introduced this season to engage younger audiences.

As this is the last purely fan-driven elimination round before the Finale, casual viewers who typically tune in occasionally are encouraged to vote this time, as the twelve acts performing this week represent the last group without a safety net beyond America’s support.

The stakes for this particular round are higher than ever. A total of twelve acts performed, with six advancing to the Finals and six eliminated, as the six acts with the highest totals from the public vote alone move forward since the Golden Buzzer is no longer in play from this point on.

This detail is crucial for longtime fans of ‘America’s Got Talent,’ as in past seasons, a struggling act could still be saved by a judge’s Golden Buzzer during the Semifinals. This year, that safety net is entirely absent, meaning even a fan-favorite act could be eliminated if it does not garner enough votes on the night.

The lineup heading into this round includes acts that survived a grueling four-week Quarterfinal gauntlet. A total of 44 acts performed across the Quarterfinals between August 18 and September 8, with eleven acts competing each week and only three advancing weekly through the public vote, plus one act sent directly to the Semifinal via Golden Buzzer.

Adding to the drama this season has been an unusually chaotic judging panel. Judge Simon Cowell required back surgery partway through the live rounds, necessitating guest judges to step in during his absence. Kenan Thompson and Heidi Klum both took turns filling the empty chair, giving this year’s live shows an unpredictable energy that fans have been buzzing about online.

Once the six surviving Semifinalists are announced, the show will move straight into its final act. The Finals will take place September 22 and September 23 at the Pasadena Civic Auditorium, with ten acts competing for the one million dollar grand prize.

This larger Finals field makes sense once you consider the acts that already secured their spots earlier in the season through Golden Buzzers, in addition to whoever survives this week’s public vote. It sets up a Finale that blends brand new breakout stars with acts that have been building momentum since the earliest Audition episodes back in June.

Fans have spent weeks speculating about who has the strongest chance of taking the title. Some have openly wondered which act stands the best chance of winning America’s vote and securing a spot in the Season 21 Finale. With names like magic duo Hundred Fingers, teen singer Lai Noelle, and robot dance act Unitree already generating serious buzz this season, the pressure on this week’s Semifinalists to stand out has never been higher.

Who do you think deserves to survive this intense round of America’s vote and make it all the way to the ‘America’s Got Talent’ Finale stage?
