They're the only team that has officially been confirmed as participating on Season 30 of "The Amazing Race" by CBS, and there's a chance that "Big Brother' couple Jessica Graf and Cody Nickson may even be the ones who walked away with the $1 million prize.

Spoiler Alert: The potential outcome of Season 30 of "The Amazing Race" is discussed below.

Season 30 of the show recently wrapped filming, and while an airdate has not been announced yet by CBS, Reality Fan Forum may have revealed that the "Big Brother" favorites were the ones to win the race. The forum follows the race as it is filmed, either with their own members who happen to be in the same locations, or by combing through social media to get more information. They once again followed along as Season 30 filmed, and according to their Timeline summary for the new season, Jessica and Cody were a part of the top three teams who made it to the final leg.

If Jessica and Cody did in fact make it to the final leg, it would place their odds at being the $1 million prize winners much higher than before, and it could mean they are in fact the winners overall. However, the placement the teams finished the race in is currently unknown.

If they did manage to win the prize, they would be the first previous "Big Brother" contestants who participated on the Race to actually win, though others have had luck in making it to the final leg. Brendon Villegas and Rachel Reilly placed third in both Seasons 20 and 24 of the competition series. Jordan Lloyd and Jeff Schroeder placed 7th during Season 16 of the show, and Alison Irwin placed 10th during the 5th Season.

Though Jessica and Cody's participation in the season is the only one that was confirmed by CBS, there have been other teams who have been reported as participating as well. IndyCar racers Alexander Rossi and Conor Daly are also rumored to be on the new season.

"The Amazing Race" Season 30 is expected to air on CBS in Spring 2018.
