His death was announced today by his mother Debbie Smith.
Brayden appeared on the long-running game show in December, and was among the last prospects who toured with host Alex Trebek before he died on November 8.
Her mother, Deborah, shared on Twitter: “We are sorry to share that our dear Brayden Smith recently passed away unexpectedly.
“We are so grateful that Brayden was able to live his dream on @jeopardy.”
Brayden died on February 5.
The game show’s Twitter account retweeted the message.
They added: “The JEOPARDY family! Heartbroken by the tragic loss of Brayden Smith.
“He was sweet, funny and absolutely brilliant. Our deepest condolences go to Brayden’s family. He will be missed. “
His cause of death is unknown.
Brayden graduated in 2020 from the University of Nevada, Las Vegas with a degree in economics.
Alex marked the star – the last five-time champion of Alex’s time as a host – “Billy Buzzsaw” because of how quickly he got through the other competition.
In a video posted by the Jeopardy! Social account in January, he spoke about participating in the show’s Tournament of Champions, calling it “something special.”
He praised Alex for “giving America a good mood” when his health was struggling.
Brayden is survived by his mother Deborah and father Scott, as well as his brothers Bryce, 26, Brock, 18 and Brody, 15.
Alex died at the age of 80 after a long battle with pancreatic cancer.
The iconic television personality had been behind the game show podium since 1984.
The Twitter show’s official confirmed the news, “Jeopardy! is saddened to share that Alex Trebek passed away peacefully at home early this morning, surrounded by family and friends. Thanks, Alex. “
