Kalshi has formed a new partnership with actor Timothée Chalamet to release a series of television commercial spots, building on the operator’s previous collaborations with fellow personalities such as Nate Diaz and Giannis Antetokounmpo.
As part of the television advertisements, Chalamet is depicted in three separate situations where the Kalshi logo eventually appears, including during a trip to the dentist’s office, while trying to quiet down noisy neighbors and while playing piano at a music store.
In a social media post announcing the collaboration, Kalshi CEO Tarek Mansour stated “in a sea of big brand commercials for the World Cup, we made something different.”
The operator formed a multi-tiered partnership with Diaz ahead of his return to combat sports on May 16, as the collaboration granted Kalshi rights to Diaz’s name, image and likeness, as well as included billboard placements and a co-branded social media campaign.
Diaz made his return to MMA in a losing effort against Mike Perry at the Intuit Dome in Los Angeles, part of the Ronda Rousey vs. Gina Carano fight card streamed exclusively on Netflix.
To extend its own efforts for the 2026 FIFA World Cup, Kalshi reached an official sponsorship agreement with the Argentina Football Association (AFA), giving the operator access to AFA intellectual property during the tournament.
The agreement covers co-branded activations, social media campaigns and use of Argentina’s sky-blue and white crest in Kalshi marketing materials. Argentina enters the tournament as the defending champion after winning the 2022 World Cup in Qatar.
Antetokounmpo, a star player in the National Basketball Association (NBA), joined Kalshi as an official shareholder in February 2026 and has since appeared in numerous television and social media campaigns with the operator.
The NBA advanced discussions with Kalshi and Polymarket on forming a new partnership with both operators on April 16, potentially joining Major League Baseball and the National Hockey League in collaborating with prediction market entities.
Kalshi asked several paid influencers to remove social media posts that questioned the integrity of the Los Angeles mayoral election on June 9, following accusations of election interference
