NXT is now live on the USA Network and so they have a much bigger audience now. However, the salaries of the NXT superstars have yet to increase.
According to a report by The Wrestling Observer Newsletter, the NXT superstars have not received any raise to their pay yet. However, it is expected they will be paid more as WWE is making a significant amount of money on the NXT contract with USA Network.
Regarding NXT, there were some noting that raises have not come yet for talent since the TV deal started. There are guys who know that the company got a $30 million a year deal from USA and NXT talent is being told they are a third brand, but most of the talent is earning less than $100,000 per year, if not all but a few.
It is expected that their pay will be raised after six months following the move to the USA Network.
