After signing a breakthrough agreement to bring live major-league American sports to free ad-supported streaming, details about Roku’s acquisition of Major League Baseball’s Sunday Leadoff games package have began to emerge.

According to The Athletic, Roku pays merely $10 million per season to stream the 18-game package through the Roku Channel.

For its part, NBCUniversal reportedly spent about $30 million to stream Sunday Leadoff on Peacock during the last two seasons. The Athletic also reported that NBCU offered the same $10 million to keep the package.

The Athletic, citing an unidentified source, also reported that the pact includes a “opt-out” clause, but it is unclear whether this belongs to Roku or MLB.

The pact is also said to be somewhat backloaded, with Roku paying $10 million this season, $8 million in 2025, and $12 million in 2026.

Sunday Leadoff premiered on Roku Channel on Sunday, with the Boston Red Sox defeating the St. Louis Cardinals 11-3.
