What is Reef Raider?
Given the rise of prediction markets, this week arguably represents the most frenzied campaign since the historic PASPA decision in 2018. Buttressed by massive capital injection from substantial funding rounds, operators have spent handsomely on celebrity endorsements. Over the last week, ads featuring LeBron James, Sydney Sweeney, Marshawn Lynch and Jeremy Piven have showered the airwaves. Even Pete Sampras, who disappeared from the public spotlight for the better part of two decades, resurfaced in a US Open spot for Kalshi.
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.

Another bettor noted that gambling debts fractured personal relationships: “Sports betting ruined my six years of friendship because I couldn’t pay back the borrowed loan from my friend. He stopped talking to me.”
Americans wagered nearly $167 billion on sports in 2025 through regulated sportsbooks, an 11% increase year-over-year, according to data from the American Gaming Association (AGA).
The blurring line between financial investing and gambling has been accelerated by the rise of prediction markets—exchanges offering event contracts that are federally regulated as financial derivatives. U.S. News found that over 40% of active sports bettors now also participate in sports prediction markets.

At a time when sports betting and predictions have reached a fever pitch, the majority of the country’s most prominent sports leagues, along with their player unions, sent a memo dated 15 September to a contingent of 35 state gaming authorities. Among proposed regulatory actions, the leagues recommend mandatory lifetime bans for individuals deemed to have “abusively harassed or issued threats of violence” against any professional athlete.
The leagues, including the National Basketball Association and the National Football League, submitted the memo as Texas Senator Ted Cruz works assiduously to pass a landmark federal framework for college athletics. While the NCAA is not a signatory to Tuesday’s letter, the advisory also urges states to pass mandatory bans for individuals who threaten “amateur athletes” along with coaches, officials and team personnel.
“Threatening the safety of an athlete or their family members over a sports bet crosses a bright ethical and criminal line, and it is entirely unacceptable,” the leagues wrote in the statement.
