“Gladiator II” opens in U.S. theaters Friday and traders are betting on how well the sequel to the 2000 Hollywood blockbuster “Gladiator” will do at the box office and in the minds of viewers.

The new film had its world premiere in Australia on October 30 and was released in Britain last week. As of Thursday evening, traders on the offshore forecasting platform PolyMarket gave the film a 38% chance of making $60-$67 million in sales in its opening weekend.

If “Gladiator II” reaches $65 million domestically, it would be the biggest opening ever for an R-Rated film in the month of November, according to SportsCasting.

Polymarket traders see a 22% chance of the film landing somewhere between $67 and $75 million in the next three days, and the same chance of pulling in $53 to $60 million. Only 10% are betting the film will make less than $53 million.

On the U.S. betting market Kalshi, traders are speculating on how well “Gladiator II” could perform on movie and TV review site Rotten Tomatoes based on its “Tomatometer” score.

The Tomatometer is determined based on the opinions of hundreds of critics, and a film is considered “Fresh” if it receives 60% or more positive reviews.

As of Thursday night, “Gladiator II” had a Tomatometer score of 72%. Traders on Kalshi at the time saw a 91% chance that the film would maintain a Tomatometer score above 70% on Monday, and a 44% chance that the score would rise above 72%.

There was only a 10% chance that the film would top the 75% of the Tomatometer after the weekend, which would give it the title of “Certified Fresh.”

“The Rotten Tomato markets are incredibly popular,” Kalshi CEO Tarek Mansour told FOX Business’ “The Claman Countdown” last week. “People love to predict the success of a movie, and it looks like the new Gladiator is going to be incredibly successful, and people are betting on its success.”

Gladiator II stars Paul Mescal, Pedro Pascal, Denzel Washington, Connie Nielsen, Joseph Quinn and Fred Hechinger.
