For Marantelli, the exchange format could also cause some customers to lose money faster than they would with a conventional sportsbook. The ability to enter and exit positions creates a perception of flexibility, but that optionality can encourage users to commit more of their bankroll.

A customer might buy a team at 55 or 56 cents expecting the price to rise to 58 or 59 cents, he explains. If it falls to 45 cents instead, the trader may refuse to accept the loss and continue holding the position.

“People will lose money faster on exchanges for lots of reasons,” Marantelli says. “It inherently increases spend, volatility, lots of things. And you’re playing against a sharper audience than you’re playing against at the DraftKings sportsbook.”

Latest ARC data revealed that US consumers purchased 25.8 million passenger trips in August 2026 (+5%), spending 19% more on air travel than they did a year ago. The average ticket price soared 17% year-over-year to $624, with economy tickets at $569 (+17%) and premium classes at $1,454 (+11%).

August’s totals set a new record for ARC-reported and settled sales, reflecting the continued strength of the U.S. travel market and continued demand,” said Steve Solomon, ARC’s chief commercial officer. “The strong summer trends from June and July carried into August, with travel to both U.S. domestic and international destinations remaining steady from the prior month and above 2025 levels.”

Air travel is booming, but Las Vegas isn’t seeing the same lift, as tourism numbers remain turbulent.

Each year, the start of the NFL season gives bonus hunters an opportunity to take advantage of generous offers from leading operators as the companies engage in a customer acquisition bonanza.

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.
