On Friday, July 31, 2026, from 4:00 PM–5:00 PM CST at the Whatnot Stage inside the Donald E. Stephens Convention Center in Rosemont, IL, fans will witness something the hobby has never seen before.
For the first time in the history of The National, a live professional fighter weigh-in and face-off will take place on the convention floor. Normally reserved exclusively for media and fight week, BKFC is bringing the excitement directly to collectors by allowing fans to watch the official weigh-in, experience the intensity of a live fighter face-off, and participate in an interactive Q&A where attendees can ask fighters questions in real time. This unprecedented experience gives fans an exclusive, behind-the-scenes look at one of combat sports’ most exciting traditions.

Throughout the event, Oh YAAS and BKFC will be handing out FREE limited-edition parallel sample packs featuring cards from the upcoming Root collection, the inaugural BKFC Experiential Collectible™ release launching this September. Fans can rip their packs on-site, download the Oh YAAS App, activate their cards, and become among the very first collectors in the world to experience the future of trading cards.
Activated sample cards unlock exclusive experiences, and collectors have the chance to win free tickets to the BKFC event of their choice, along with exclusive collectibles, experiences, prizes, and additional surprises only available through the Oh YAAS platform.
The Root collection represents the first-ever Experiential Collectible™ trading card release, combining authenticated physical collectibles with immersive digital experiences, exclusive rewards, augmented reality, and fan engagement that continues long after opening the pack.
“BKFC has always challenged convention, and this event is no different,” said David Feldman, Founder & President of Bare Knuckle Fighting Championship. “Bringing our fighters to The National for the first live weigh-in and face-off in the show’s history gives fans an experience they’ve never had before. Pairing that with Oh YAAS’ groundbreaking trading cards creates something truly special for collectors and fight fans alike.”
“For more than 150 years, trading cards have been something you collect. We believed they could become something you experience,” said Scott Terrell, Founder & President of Oh YAAS. “The Root collection is the world’s first Experiential Collectible™, where every activated card unlocks unique experiences, rewards, and opportunities. Launching our inaugural BKFC release at The National alongside Whatnot is the perfect way to introduce collectors to the future of the hobby.”
“Whatnot is built around bringing collectors together through unforgettable live experiences,” said Josh Reilly, Marketing Manager at Whatnot. “Hosting the first-ever BKFC fighter weigh-in and face-off at The National, while giving collectors exclusive sample packs and streaming the entire experience live, perfectly captures what our community loves most, being part of history as it happens.”
