While Polymarket pulled off a coup with the signings of James, Eli Manning and Derek Jeter, a Novig ad featuring Sweeney arguably received as much fanfare. Sweeney, an Emmy Award-nominated actress known for her role in HBO’s Euphoria series, stars in the spot titled “Just Sports.” As of Friday afternoon, the Novig post on social media platform X received at least nine million views.
Throughout the ad, Novig throws shade on its rivals for offering niche markets on events such as the timeframe for when traders believe that Venezuelan President Nicolás Maduro will be removed from office. Unlike operators such as Kalshi and Polymarket, Novig has opted to limit its offerings to purely sports. “No betting on wars, or deaths…or politics,” Sweeney mused.
During the 2025-26 NBA season, Kalshi made waves by granting an equity stake to two-time league MVP Giannis Antetokounmpo. According to the Wall Street Journal, Sweeney’s representatives approached Novig to express interest as a potential investor. Eventually, the company granted her an undisclosed amount in equity. The increased role of celebrity endorsements in the space is a trend that will likely receive closer observation in the coming months.

“If we just sold the data to Kalshi in order to list the markets but no one was coming in and placing liquidity, there’s no point in them listing the markets,” Monk said. “We also need to supply the data to the market makers to inform their models.”
Catalist initially received a list of fewer than 10 potential market makers from Kalshi. It has since completed agreements with close to 20 and is engaging with approximately another 20.
That growth reflects the expanding number and variety of sports contracts. ITF tennis is particularly dependent on official data because its more than 60,000 annual matches are not generally televised. Unofficially monitoring a tour moving between locations such as Bogotá and Bali would be difficult, Monk noted.

The company also highlighted its own research that suggests over 80% of consumers cannot “confidently distinguish” licensed operators from unlicensed ones.
Stella David, Entain’s CEO, called for the government to move ahead with the ban immediately, arguing clubs were already aware of the planned changes.
“Premier League clubs that have struck new deals with unlicensed gambling operators knew the risks,” she said. “The government made clear in February that it would bring in a ban and it should do so immediately: even if that means clubs ordering new kit mid-season.
