Wilder has been ordered to defend his WBC title against Dominic Breazeale after Tyson Fury opted to face another opponent before a potential rematch with the "Bronze Bomber".
Confirmation of the long-rumoured tie-up paves the way for a third fight between Golovkin and Canelo Alvarez, who signed a US$365 million contract with DAZN in October.
But Wilder, Haymon and Finkel have a poor relationship with Hearn and to get a deal with Wilder done, Hearn said it would be up to Skipper to negotiate a deal as he had done with Golovkin and Alvarez.
"It's not just about doing a deal with Wilder, it's about doing a deal with Joshua, for the fight". There's a clear desire from both sides to make the fight.' He added: 'If an undisputed fight gets made, it will be November or December 2019.
In-turn, Matchroom Boxing CEO, Eddie Hearn, offered Wilder a multi-fight deal that would have given him $30 million for a fight with Joshua.
"Gennady Golovkin is a generational talent with global appeal", added DAZN Group executive chairman John Skipper.
That's not to say Wilder isn't interested in the fight against Breazeale, but would rather have it on Fox, where it is free to watch in the United States.
But if Wilder signs with DAZN, the Breazeale fight would be the first of the deal.
With DAZN already televising Joshua's fights in America - including the June 1 clash with New York's Jarrell Miller in Madison Square Garden - their move for Wilder revives hopes that they will fight each other at the end of this year.
The double fight deal would lead into an undisputed heavyweight unification bout with Joshua over two fights in 2020.
"Clearly the relationship between Team Wilder and Team Joshua isn't the best".
There are, of course, many details to iron out, including the prospect of a two-fight deal where each fighter has the right to an immediate rematch and the location of the fight.
"Pay-per-view for me is definitely those big moments, those special magical moments for fights that people have to see".
"It's all well and good making an undisputed fight but if you lose to Miller, it's all up in the air".
