Who won Jeopardy! on December 4, 2025?

Jeopardy! season 42 featured a triple stumper in a confusing clue during the Final Round of the 64th game, which premiered on Thursday, December 4, 2025, when all three participants wrote the same response.

Ron Lalonde, who overthrew two-game champion Libby Jones in the previous episode, competed against two new players: Marie D’Avignon, a VP of operations from Durham, North Carolina, and Andy Luo, a student success coach originally from Johns Creek, Georgia.

A medical physicist from Pittsburgh, Pennsylvania, Ron entered the Alex Trebek Stage as a one-day champ with winnings of $15,201.

As the game proceeded, Andy found the Jeopardy! Round Daily Double, betted it all and got it correct, coming second.

He found the first Daily Double as well, wagering $4000, but answered incorrectly. Ron got the last Daily Double, wagering $4,000, and his answer was correct.

The Final Round saw all the wrong answers by players; hence, Jon, who had the highest score, won the game and became a 2-game champion.

The Final Jeopardy! question on season 42, game 64 of Jeopardy! in the category “The Supreme Court in the 19th Century” was:

Citing the “language of the people whether sellers or consumers”, in 1893 the S.C. ruled on the botanical designation of this

Correct answer: What is a tomato?

Final Jeopardy! Round

The Final Jeopardy! was quite surprising as neither of the three players got the correct response, resulting in a triple stumper to the clue from the category "The Supreme Court in the 19th Century."

Ron's runaway made him the winner who would now compete for the third game.

The final scores are:

• Ron Lalonde: $20,400. (2-day total is $35,601.)  (What is tobacco?)
• Andy Luo: $399. (What is tobacco?)
• Marie D’Avignon: $201. (What is tobacco?) 

Ron Lalonde will compete on Friday, December 5, 2025, for his third Jeopardy! game competing against two new players: Youssef Shareef, a cashier from Houston, Texas, and Margaret Dunlap, a writer from Burbank, California.
