The NBA's exclusive negotiating window with Disney and Warner Bros. Discovery expires on Monday and sources tell CNBC that it will likely pass without a deal.

Both Disney and WBD are in active talks with the NBA to keep games on ESPN and TNT.

The NBA would like to bring in at least one new partner to serve as a flagship streamer.

Beginning on Monday, the NBA can open negotiations with Amazon, Apple, YouTubeTV, Peacock and Netflix, who have all had preliminary conversations about potential interest.

“We continue to have productive discussions with Disney and Warner Bros. Discovery on a renewal of our media deals,” a league spokesperson said in a statement to CNBC.

TNT has shown NBA games since 1988, while ESPN's deal with the league began in 2002.

The NBA is looking to double the $24 billion it generated from its previous media rights deal with Disney and Warner Bros. Discovery by adding new partners and charging more for rights.

Last year’s NBA playoffs was the most watched in 11 years across TNT, ABC, ESPN and NBA TV, according to Nielsen.
