Polymarket Signs LeBron and Spike Lee to Build Its Own Ad Universe
Polymarket is building its own comedic 'ad universe', signing A-listers including LeBron James, Spike Lee and Derek Jeter into celebrity 'Squads' as the prediction-market platform fights for mainstream US attention.
Prediction markets are having a moment, and Polymarket wants to own it — not by buying ads, but by building its own entertainment franchise. The platform, where users bet on the outcome of everything from elections to award shows, has recruited a roster of A-list names to anchor a recurring, sketch-style ad world rather than a one-off celebrity endorsement.
What Polymarket is actually doing
The campaign, developed with Stagwell's creative shop Today on the Moon, drops stars including LeBron James, Spike Lee, Derek Jeter and Craig Robinson into a fictional office, forming competing 'Squads'. It is deliberately comedic and serialised, designed to be returned to like a show rather than skipped like an interruption. Reports put LeBron James's deal alone at around $15 million a year, a sign of how seriously Polymarket is treating brand-building.
Why a betting platform is spending like a studio
Prediction markets are a young, crowded and lightly understood category, competing hard for US users against rivals such as Kalshi. Celebrity and comedy do two jobs at once here: they lend legitimacy to an unfamiliar product and they make the brand feel culturally safe to try. When a category is new, the brand that feels most famous often wins by default.
There is a strategic shift hiding in plain sight. Instead of renting attention through media buys, Polymarket is manufacturing its own — an owned, repeatable format it controls and can extend. That is the same logic behind brand mascots and long-running ad characters, updated for a social-video age where a recurring cast can travel across TikTok, YouTube and Instagram on its own.
The takeaway for smaller brands
You will not sign LeBron. But the transferable idea is to build a repeatable comedic world rather than scattershot one-off posts. A recurring character, a running joke, a format your audience recognises — these compound over time in a way that a stream of disconnected ads never does. Consistency of world beats novelty of execution.
The risk is that celebrity can drown the message. Polymarket's bet only pays off if people remember the brand and the category, not just the famous faces. For any business borrowing fame, the test is simple: take the celebrity out of the ad, and does anyone still know what you sell?

Why use comedy and celebrity for a betting brand?
For a new, lightly understood category, fame and humour build quick legitimacy and cultural permission to try the product — often more effectively than explaining the mechanics.
What I love here is the shift from buying attention to building it. A recurring cast in a world you own is an asset; a one-off celebrity post is a rental. Most small brands could borrow the thinking — pick a format, repeat it, and let people look forward to the next one. — Daniel Nikolla, Founder of Merx Marketing
Challenger brands win by building an owned, repeatable world — not by renting attention one post at a time.
