A media merger of super hero proportions is about to be settled.

A federal judge is expected to decide Tuesday whether AT&T should go ahead with its planned $85 billion acquisition of Time Warner, home to DC Comics’ heroes Batman, Superman and Wonder Woman, as well as CNN and HBO, the premium network where Game of Thrones resides.

The deal will have far-reaching repercussions for consumers, bringing together the nation’s largest telecommunications company and owner of DirecTV with Time Warner’s entertainment library. An AT&T victory is likely to bolster the variety and number of streaming services competing for Americans’ wallets and time as they ditch traditional options such as cable. But according to the Trump administration, it could raise costs for consumers.

Either outcome will send up the equivalent of a bat signal to other communications and entertainment companies, alerting them to whether they should push forward with their own acquisitions aimed at bolstering their competitive position against companies such as Netflix, Amazon and Apple.

Efforts by AT&T to buy Time Warner started 20 months ago. But the Department of Justice sued, arguing AT&T — whose reach extends to pay-TV, wireless and Internet broadband — would have the leverage to force rival pay-TV providers to pay hundreds of millions of dollars more annually per year for the right to distribute Time Warner’s networks. Those higher costs would be passed on to consumers, the government said.

AT&T has countered that the deal would actually help consumers, allowing the bigger company to better compete with a growing roster of online video competitors. Revenues have stagnated in the saturated wireless industry, as have traditional pay-TV revenue from AT&T’s DirecTV satellite service and U-verse fiber-delivered TV service.

Suspense about the outcome has been building since a six-week trial ended April 30. A new twist emerged in early May: the revelation that the telecom giant paid President Donald Trump’s personal lawyer Michael Cohen $600,000 for consulting services at the time the company was seeking regulatory approval for the merger.
