“Good Morning America” anchor Josh Elliott wants ABC to open up the checkbook and give him a big raise.

Page Six says that Elliott is in tense contract negotiations with ABC after upping his demand for a salary raise equivalent to that of co-anchor Robin Roberts.

Sources tell Page Six that after Roberts closed a long-term contract with ABC, worth about $14 million a year, agents for Elliott have upped their demand for “an equally significant bump in salary.”

One source told us, “Josh started as news anchor, but his role has increased significantly and he is an integral part of the success of the show. He is not asking for as much money as Robin, but an equivalent raise.”

We’re told his reps have also talked to NBC News, but the focus is for him to sign a new contract with ABC. One network insider told us, “It would be a blow to lose Josh, so everyone is focused on reaching a deal.”

Elliott joined in April 2011, and a year later “GMA” broke the “Today” 16-year winning streak.

An ABC rep said, “We are in negotiations with Josh. It is no surprise that there is a lot of interest from other networks. He is an important part of the GMA family, and we want him to stay part of the family.”
