Party Poker, at least the US-facing branch of the company, has been a bit of an enigma since launching in New Jersey in late 2013. The company was bullish on New Jersey and the US in general at the time and was among the biggest spenders in the early land grab. They've drastically reduced spending there in recent years, however, and have become one of the state's poorest performing operators.
Pennsylvania has now legalized online gambling, and the possibility is real for online poker sites to span multiple states. GVC Holdings, the parent company of Party Poker since 2015, appears to be once again reevaluating their potential in the United States.
