SYDNEY SWEENEY DIDN'T JUST ADVERTISE A BETTING STARTUP. SHE BECAME AN OWNER.
How one Hollywood star turned a celebrity endorsement into an equity deal — and helped a sports prediction company grab the internet's attention.
1. THE DIFFERENCE BETWEEN BEING PAID AND OWNING A BUSINESS
When celebrities promote a company, the usual arrangement is simple: the brand pays a fee, the celebrity appears in an advertisement, and both sides hope the campaign generates sales.
Sydney Sweeney chose a different route.
In September 2026, the Euphoria actress joined Novig, a sports-focused prediction market platform, as a strategic partner and equity holder. Instead of simply lending her face to the company, she acquired an ownership stake and helped shape its advertising campaign.
The size of her stake has not been publicly disclosed.
That distinction matters. A celebrity who receives a fixed endorsement fee can earn money regardless of whether the company eventually succeeds. An investor, however, can benefit if the business grows in value — but also risks losing money if it fails.
Sweeney was no longer just promoting the product. She had a financial interest in its future.
2. WHAT EXACTLY IS NOVIG?
Novig operates in the growing prediction market industry, where users trade contracts linked to the outcomes of events.
Its positioning is deliberately narrow: sports only.
While competing platforms offer markets covering subjects such as politics and other current events, Novig focuses on sporting competitions. Its message is designed to appeal to fans who want to trade on their knowledge of games, teams and players.
The company was founded in 2021 by Jacob Fortinsky and Kelechi Ukah. By 2026, it was competing in a market attracting substantial investor interest and attention from major celebrities.
But entering a crowded industry creates a difficult problem: how can a relatively young company make people remember its name when better-known competitors have significantly greater resources?
Novig's answer was to combine a celebrity partnership with an advertisement designed to provoke a reaction.
3. THE CAMPAIGN THAT EVERYONE STARTED TALKING ABOUT
Released in September 2026, Novig's “Just Sports” campaign featured Sweeney posing with sports equipment while delivering a provocative message about the platform.
The advertisement quickly generated attention, but it also triggered criticism. Some viewers and female athletes argued that its sexualised presentation distracted from sport and reinforced negative stereotypes about women.
Others focused on the marketing strategy itself: a relatively unfamiliar company had suddenly become part of a much larger cultural conversation.
The campaign attracted substantial engagement on social media, reportedly outperforming a comparable promotional post from the much larger prediction market platform Polymarket in Instagram likes.
That is a striking result for a startup competing against companies with far bigger profiles.
However, there is an important distinction between attention and business performance. Viral engagement does not automatically translate into new customers, profitable trading activity or long-term loyalty.
Novig still needs to demonstrate that the attention can produce lasting commercial results.
4. WHY AN OWNERSHIP DEAL CAN BE MORE POWERFUL THAN A CELEBRITY FEE
Sweeney's arrangement combines three roles: investor, strategic partner and advertising collaborator.
Each contributes something different.
As an investor, she has a potential financial incentive to help Novig increase in value.
As a strategic partner, she can contribute to how the company presents itself and reaches customers.
As a creative collaborator, she can help develop a campaign rather than simply appear in one.
This arrangement can align the interests of the celebrity and the company more closely than a conventional endorsement. If the business succeeds, both sides may benefit.
But equity deals also involve uncertainty. The value of a private company's shares can change dramatically, and investors may be unable to sell their holdings quickly. Even a high-profile partner cannot guarantee a successful business.
The terms of Sweeney's investment remain private, so her potential financial return cannot be calculated reliably.
5. THE BUSINESS STRATEGY: SELL ATTENTION BEFORE YOU SELL THE PRODUCT
For a startup, competing on advertising budgets is often unrealistic. Established rivals can spend enormous amounts on television campaigns, sponsorships and digital advertising.
A smaller company needs another advantage.
Novig's campaign illustrates one approach: create an event that people want to discuss, then make sure the company's name is attached to that conversation.
The strategy has several potential benefits:
Lower barriers to visibility: a controversial campaign can attract attention that would otherwise require a much larger advertising budget.
A recognisable identity: the “Just Sports” message gives Novig a clear position in a crowded category.
Organic distribution: people discussing or criticising an advertisement can spread it beyond its original audience.
Investor and customer interest: increased visibility may encourage people to investigate the business.
Yet controversy has costs. Negative reactions can alienate potential customers, distract from the actual product and make the brand dependent on its next viral moment.
The real test is whether people remember Novig because they want to use its platform — not simply because they remember the advertisement.
6. THE RISK OF MAKING THE CELEBRITY BIGGER THAN THE COMPANY
Celebrity marketing creates an unusual challenge for young businesses.
A famous person can become the main attraction, leaving the company itself in the background.
In Novig's case, people may remember Sweeney's appearance without understanding how the platform works, why it is different from competitors or whether it offers an experience worth returning to.
There is also a trust question. Because Sweeney owns part of the company, she could benefit financially from its success. That is materially different from an ordinary paid endorsement, and audiences should be able to understand that relationship when they encounter promotional content.
For the company, transparency and product quality matter just as much as publicity.
Novig must ultimately compete on factors such as usability, customer confidence, market quality and its ability to retain users. A memorable advertisement can introduce a business to millions of people, but it cannot replace a compelling product.
7. MAACAT PERSPECTIVE
Sydney Sweeney's partnership with Novig demonstrates how celebrity marketing is evolving. The traditional model paid famous people to promote businesses. The newer model can give them a direct financial stake in the businesses they help build.
That changes the relationship. A celebrity becomes more than a spokesperson: their reputation, creative decisions and financial interests become connected to the company's future.
For startups, the lesson is not that every business needs a famous investor or a controversial advertisement. It is that the right partnership can provide access to attention that money alone might struggle to buy.
But attention is only the beginning.
A viral campaign can make people notice a company. A valuable business must give them a reason to stay.
