Reports emerged over the past few days claiming the streaming service were prepared to pay astronomical figures to secure Wilder, having met with the Bronze Bomber and his co-managers, Shelly Finkel and Al Haymon, in NY on Tuesday.
And according to World Boxing News, DAZN tabled him a mega contract.
Joshua's promoter Hearn said earlier this week there was "a clear desire from both sides to make the fight", and that it could be scheduled for November or December this year if a deal could be struck.
The deal included two bouts with unified heavyweight king Anthony Joshua in 2020.More news: Christchurch residents pay tribute to victims

Hearn insists Joshua has not been distracted ahead of his fight with the unbeaten Miller, saying: "I spoke with AJ on the days of those meetings [about the potential fight with Wilder], he was just like "let me know".
Wilder is now mulling over the agreement, which would reportedly include a fight with compatriot Dominic Breazeale worth around $20m (£15m) and two fights with Joshua which could land him $40m (£32.5m) apiece.

It's another spanner in the works.
However, after the proposed deal fell through, Joshua went on to face Russian Alexander Povetkin, while Wilder took on Tyson Fury.
"Big Baby Miller is a top-10 heavyweight, so if he's not fighting Wilder or Fury, then Big Baby Miller is on the shortlist of people I'd want him to fight".
