The Caesars and Tropicana casinos are joining New Jersey's growing sports betting market, and FanDuel's mobile betting app has gone live.

And William Hill US is expected to do so on Friday with its casino and racetrack partners.

The Tropicana announced Thursday it has reached a deal with William Hill Race & Sports Book to offer sports betting in the near future.

No timetable was given for the launch.

Hours later, the New Jersey Division of Gaming Enforcement said Caesars began online and mobile sports betting, a surprising move for a casino that had not said anything about sports betting plans.

The FanDuel sports betting app also went live Thursday.

New Jersey gambling outlets took in $40.6 million in sports wagers in July, the first full month it was legal.
