Timothée Chalamet faces fan criticism after appearing in Kalshi ad campaign

Timothée Chalamet’s new Kalshi advert has sparked debate among fans over actor’s latest endorsement

Timothée Chalamet has drawn mixed reactions online after appearing in a new advertising campaign for prediction market platform Kalshi, with some fans questioning the actor’s decision to endorse the company.

The 60-second advert, which has reportedly attracted more than six million views, features Chalamet in a series of unusual scenarios. The advert is directed by Academy Award-winning cinematographer Linus Sandgren.

The campaign has generated discussion online due to the nature of Kalshi’s business model. According to sources, the platform operates legally because it is classified as a financial trading marketplace rather than a gambling service. Users can speculate on the outcomes of events ranging from current affairs to entertainment awards.

The platform has previously attracted controversy. The source notes that Kalshi faced criticism over reports of a proposed market linked to deaths, leading chief executive Tarek Mansour to state that such listings were not offered.

The report also referenced allegations involving former politician George Santos, though no further details were provided.

Several posts shared by critics referenced Chalamet’s previous comments about pursuing artistic excellence.

Others joked about his courtside appearances at basketball games or compared the endorsement with his recent film work.

Comments included, “A Kalshi ad? I thought you wanted greatness, man,” “Gambling is a poison.” while another user wrote, "I'm not even surprised anymore. Hollywood must have really did a number on him."
