Sweeney's controversial playbook
Sydney Sweeney generates massive buzz with provocative ads, but she's not just the face. She engineers the campaigns, takes equity stakes, and outperforms competitors spending far more.
Novig's sports betting ad
Sweeney's latest campaign for sports prediction startup Novig shows her barely clothed, using sports gear as cover. The minute-long video generated tens of millions of views across X and Instagram.
Equity over endorsement

Rather than taking a simple endorsement check, Sweeney negotiated a shareholder stake in Novig. The CEO says she approached them specifically because of their exclusive focus on sports markets.
Outperforming bigger budgets
Polymarket spent an estimated $15 million annually on LeBron James alone, plus millions more on other celebrities. Yet Novig's Sweeney campaign generated 22 times more Instagram likes with a smaller investment.
Creative partner, not just talent
Sweeney served as a hands-on mastermind, shaping every stage of the campaign. She chose the music, guided camera angles, and revised the script herself.
A competitive weapon
For early-stage platforms competing against heavily funded incumbents, a viral endorsement can be a vital equalizer. Sweeney put Novig into the same cultural conversation as Polymarket within hours.
“She's not even a simple endorsement, she's a competitive weapon.”
The Dr. Squatch bathwater moment
In October 2024, Sweeney appeared in a bubble bath ad for men's personal care brand Dr. Squatch. She then pitched selling limited-edition soap made with her actual bathwater, which sold out in seconds.
American Eagle's fading buzz
Sweeney's July 2025 campaign for American Eagle drew controversy over its slogan 'Sydney Sweeney Has Great Jeans,' which some interpreted as a eugenics reference. Initial sales surged, but the company later disclosed no sustained growth.
Virality has limits
A year after the American Eagle campaign, the company's stock returned to pre-campaign levels. Controversy and celebrity partnerships create momentum but can't compensate for weak product or unclear brand identity.
“Advertising, marketing, [and] partnerships with celebrities can absolutely create momentum, but [they] can't really compensate indefinitely for product, merchandising, and unclear brand identity.”
The Novig risk ahead
Novig risks becoming a supporting character in its own advertising, overshadowed by Sweeney's star power. How the company evolves the partnership will determine whether it creates lasting value.
“Being bold is part of brand building. Don't shy away from [it], but recognize that it shouldn't be for short-term gimmicks because that can only take you so far.”
The short version
Sweeney's hands-on creative control and willingness to embrace controversy generates outsized viral engagement, but sustained business impact requires more than buzz.
