‘American Ninja Warrior’ Season 18 Episode 13 Release Date, Time, Where to Watch and Preview

The eighteenth season of ‘American Ninja Warrior’ is heading into its final stretch, and episode 13 promises to close out one of the most competitive years the show has staged. ‘American Ninja Warrior’ Season 18 premiered in June 2026 on NBC, with all 13 episodes of the season airing at 8 p.m. ET on Monday nights and episodes pre-taped rather than live. As the National Finals wind down, viewers are eager to know exactly when the finale drops and what it will deliver.

The season premiered on Monday, June 8, and introduced major competition updates, including a supersized three-lane racecourse, new regional Qualifiers and Finals, and an all-racing National Finals built around a $250,000 prize. That new format has shaped the drama building toward the last episode of the year.

‘American Ninja Warrior’ Season 18 Episode 13 Release Date

Episode 13, titled National Finals 4, is set to air August 31 and marks the last night of the national finals. It follows directly on the heels of episode 12, National Finals 3, which continued the third night of competition as the remaining ninjas raced for a spot in the closing rounds.

Episode 12 aired August 24, continuing the show’s established Monday night pattern for the season, which puts episode 13 exactly one week later on the calendar. That steady weekly rhythm has held since the premiere and gives fans a predictable window to plan their viewing.

According to Rotten Tomatoes, episode 13 airs August 31 and covers the last night of the national finals, where only one ninja can be crowned ‘American Ninja Warrior’ champion. The listing also confirms the finale caps what has been described as a record-breaking season for the women’s field.

The finale arrives at the end of a summer that has tracked dozens of competitors through revamped qualifying rounds, so the stakes for this final broadcast are considerably higher than a typical midseason episode.

Where to Watch ‘American Ninja Warrior’ Season 18 Episode 13

New episodes of ‘American Ninja Warrior’ Season 18 air on Mondays at 8 p.m. ET on NBC, streaming the next day on Peacock. That pattern applies to the finale just as it has to every episode since the season began.

There are 13 episodes total in the season, and all of them are pre-taped, meaning there are no live broadcasts to account for. Viewers without cable access can still catch the finale through NBC’s streaming partner the following day.

For anyone who has followed the season through its various regional rounds, the viewing setup for episode 13 will feel familiar. The show has not altered its distribution model even as the competition format itself changed significantly this year.

‘American Ninja Warrior’ Episode 13 Preview and What Happens

Continuing the competition tweaks introduced last season, Season 18’s National Finals follow an action-packed, all-racing format, with the winner taking home the $250,000 grand prize. That structure culminates in episode 13, where the men’s champion will finally be decided.

New this year, a Women’s Bonus Tournament gives the top four female competitors a chance to race for the title of 2026 Women’s Champion and a $50,000 bonus prize, with the tournament unfolding across three single elimination races during the season finale. The ranking for that bonus tournament is measured by the number of obstacles conquered, a detail that has kept fans debating positioning heading into the finale.

Utah siblings Kai and Luke Beckstrand and their sister Baylee are among the competitors expected in the closing rounds, alongside other finalists who advanced through the season’s revised National Finals structure. The National Finals themselves opened with 60 ninjas competing in a round robin of head to head races before narrowing down to the bracket tournament that plays out across the final broadcasts.

Season 18 Format Changes Leading Into the Finale

This year’s competition looked different from the start. Season 18 introduced region based Qualifiers and new Regional Finals featuring a high speed Tripleheader three lane racecourse, a format that replaced the more traditional single lane obstacle runs of earlier seasons.

Round 1 of the Regional Finals used a six obstacle course, with the fastest 14 men and six women advancing to Round 2, where the Tripleheader put ninjas head-to-head-to-head in high speed side by side races, sending only the top two from each heat on to the National Finals. That funnel is what produced the field now converging on episode 13.

Hosts have remained a constant throughout the shakeup. Matt Iseman and Akbar Gbajabiamila have anchored the season alongside co-host Zuri Hall, guiding viewers through both the new regional structure and the National Finals that follow.

With the men’s title and the inaugural Women’s Champion crown both on the line in the same broadcast, ‘American Ninja Warrior’ fans have plenty to weigh in on once the buzzer sounds for the final time this season.
