In a letter released to Netflix shareholders on Tuesday (July 24), CEO Reed Hastings and chief financial officer David Wells had hinted at the possibility of working with the cable network.
"While we compete for content and viewing time with HBO, it is also possible we will find opportunities to work together - just as we do with other networks," the letter stated.
However, HBO spokesperson Jeff Cusson told Reuters: "We are not in discussions and have no plans to work with Netflix."
HBO has its own on-demand service HBO Go, which is available to its subscribers.
The network's current programming slate includes shows such as Game of Thrones, Boardwalk Empire and The Newsroom.
