Twelve acts. Six spots. One night to decide it. America’s Got Talent Season 21 hits its Live Semifinal on Tuesday, September 15, and by the time Wednesday’s results show wraps, half the field will be headed home while the other half joins an already-stacked Finale lineup. Here’s who’s actually competing, how they got here, and where the smart money should go.

How the Format Works This Season

This isn’t a simple “top vote-getters advance” round. Per the season’s own rules, one of the 12 Semifinalists will receive a collective judges’ Golden Buzzer straight into the Finale — the last one of the season, since the judges’ buzzer stops being in play after this round.

From the 11 who remain, the six with the highest public vote totals move on. That means five of these twelve acts go home Wednesday night, and the sixth spot isn’t decided by vote share at all — it’s decided by which act the four judges can agree on together.

Four acts have already locked in their Finale spots without touching Wednesday’s vote: Hundred Fingers (Howie Mandel’s Golden Buzzer), Nene Royal (Mel B’s Golden Buzzer, for a searing cover of Soundgarden’s “Black Hole Sun”), Lai Noelle (Kenan Thompson’s Golden Buzzer while guest-judging for the recovering Simon Cowell), and Unitree (Sofía Vergara’s Golden Buzzer for a blade-wielding robot dance routine that had Howie Mandel comparing it to I, Robot).

They’re not part of Tuesday’s competition, but they set the bar the other 12 have to clear on the night.

The Field: 12 Semifinalists

  • Royal Lasers — light-up dance trio, entered the live shows on Terry Crews’ Golden Buzzer from auditions
  • Olivia Befus — teenage dog trainer, advanced from Quarterfinals Week 1 in an emotional first-vote result
  • Luke Taleno — bilingual rapper, entered on Howie Mandel’s audition Golden Buzzer
  • Come Here — Korean dance group, beat out Patrox for their semifinal spot
  • Veronika Goroshkova — aerialist, entered on Sofía Vergara’s audition Golden Buzzer, known for a “death drop” stunt
  • Geno Ploeger — magician, advanced comfortably over Nyjah Music & Zyah Rhythm
  • Kameron Marshall — Canadian card magician, beat out fellow Golden Buzzer alum Pynk Beard for his spot
  • Acro Canine Crew — five-dog acrobatic act, first dog act in AGT history to receive a Golden Buzzer (Terry Crews, auditions)
  • Daniel Alvarez — comedian, edged out aerial duo Holland & Sienna in a result fans called a genuine upset
  • Young & Strange — British magic duo, praised for a “Las Vegas-style illusion” complete with a confetti finish
  • Cesar Dias — Portuguese singing comedian, whose quarterfinal performance literally caught fire mid-song and still won the judges over
  • Travis Garland — singer, delivered a full reinvention of Ariana Grande’s “Dangerous Woman” that left Mel B repeating “wow” four times in a row

Our Predictions: Likely to Advance

Veronika Goroshkova

Her Golden Buzzer pedigree, her genuinely dangerous aerial work, and the fact that she was the first name called safe in her quarterfinal round all point to a large, consistent base. Aerial and danger acts tend to translate well to viral clips, and hers already has.

Acro Canine Crew

Dog acts are close to guaranteed AGT gold, and this one has the added hook of being the first dog act ever to earn a Golden Buzzer, plus unanimous standing ovations in the quarterfinal. The risk is splitting the “family-friendly” vote with Olivia Befus — but the acrobatics angle gives them a different lane than a straightforward dog-tricks act.

Royal Lasers

A visually massive, TikTok-friendly spectacle act with a Golden Buzzer origin story and consistent judge enthusiasm since auditions. Spectacle acts with strong production value have historically over-performed their “talent difficulty” in the vote, and this trio leans hard into that.

Cesar Dias

The “performance literally caught fire and he still won the room” storyline is exactly the kind of chaotic, human moment that drives sympathy voting and social shares. Sofía Vergara has been vocally in his corner since auditions, and comedy-adjacent music acts with a big personality tend to have staying power.

On the Bubble

Three magic acts made it into this same field of 12 — Young & Strange, Geno Ploeger, and Kameron Marshall — and that’s the single biggest variable of the night. Magic voters are loyal but limited in number, and with three acts competing for the same slice of that audience, at least one is likely to underperform relative to how well they’ve actually been received by judges.

  • Young & Strange — the strongest judge reviews of the three (“I could see this in Vegas,” per Heidi Klum), but competing directly against two other magicians for the same vote pool.
  • Kameron Marshall — momentum from beating a Golden Buzzer act in the quarterfinals, but card magic is a harder sell live than illusion or dog-and-pony spectacle.
  • Geno Ploeger — advanced comfortably last round, but with the least distinct “hook” of the three magicians heading into a more crowded semifinal field.
  • Come Here — dance crews can struggle to stand out in a field this stacked with novelty acts (dogs, robots, fire), even with strong choreography.
  • Luke Taleno — genuine emotional storyline and a Golden Buzzer pedigree, but rap acts have historically had a tougher time converting AGT’s more music-theater-leaning voter base into Finale spots.

Our Predictions: At Risk of Elimination

Daniel Alvarez

His quarterfinal win was already framed by recappers as an upset over a fan-favorite aerial duo, which suggests his support, while real, may be narrower than acts with more universal-appeal hooks like dogs or spectacle.

Travis Garland

The judge reaction was arguably the loudest of the night, but a bold, unconventional song choice split even Mel B’s own reaction (“wouldn’t have chosen that song,” followed immediately by praise) — that kind of divided response can translate to a divided vote.

The Wildcard Factor

AGT’s semifinal results have a well-documented history of defying judge enthusiasm. Just one round ago, Lara D — a previous Sofía Vergara Golden Buzzer recipient who nearly earned a second one on the spot — was eliminated anyway, and Simon Cowell’s own Golden Buzzer pick, parkour athlete Ruben Roldan, went home the same night. Judge love does not reliably convert to votes, and with three magicians splitting one audience and two dog acts splitting another, Wednesday’s results are genuinely one of the harder semifinals to call in recent seasons.
