Timothée Chalamet stars in Kalshi ad campaign fanning backlash
Actor Timothée Chalamet appears in a new advertising campaign for CFTC-regulated prediction market platform Kalshi, with the project described as an offbeat film or commercial series. The campaign, which went live around June 12, drew social media backlash from some fans who criticized the partnership as inappropriate, with comments cited including framing gambling as harmful and one user writing, 'Gambling is a poison.' Critics questioned why the Oscar-nominated actor would endorse the platform, with Reddit threads comparing the endorsement to celebrities filming commercials in Japan to avoid domestic reputational risk. No details on contract terms, creative team, or distribution strategy were disclosed.
Kalshi must now show that Chalamet's cultural reach actually funds new trading accounts, not just generates controversy. If brand awareness doesn't convert to volume, the platform burns marketing budget without closing the retail gap against Polymarket.
Chalamet joins a celebrity ad push now spanning Messi and Giannis Antetokounmpo as Kalshi races Polymarket's Rick Rubin commercial and Media podcast for retail trader attention during the World Cup window.
