Who won Jeopardy! on December 3, 2025?

Jeopardy! season 42's latest episode, which premiered on Wednesday, December 3, 2025, saw returning champion Libby Jones enter the stage to play her third game after winning an impressive $70,802 in two games.

Libby Jones, a recruiter from Davenport, Florida, competed against Ron Lalonde, a medical physicist currently based in Pittsburgh, and Sarah Murphy, a freelance transcript editor from Hamilton, Ontario.

Libby, however, competed against only Ron Lalonde in the Final Round, and could not continue her winning streak on Jeopardy! as she answered incorrectly. Sarah was unable to participate due to her negative score, which did not meet the criteria to continue.

Ron answered correctly, becoming the second Lalonde twin to win on the show, as his identical twin brother Ray won 13 games in December 2022, earning a total of $388,400 and ranking in the top 20 on Jeopardy! players of All-Time Regular Play at number 13.

While Libby got it wrong in Final Jeopardy! ending her two-game streak, wagering only $7,999 by the end of the game, she wrapped up her three-day appearance with a total of $73,802.
