The NBA’s free agency negotiation window opens up Tuesday, June 30 at 6 p.m. ET, and there will be no shortage of interest in James’ services.

The Golden State Warriors are “at the front of the line in pursuit of LeBron James,” per NBA insider Marc Stein . ESPN’s Shams Charania reporte d on Monday that the Warriors had a goal to assemble a “big four” of James, Stephen Curry , Draymond Green and Anthony Davis , who currently plays for the Washington Wizards . Despite reports from ESPN’s Brian Windhorst that a trade for Davis is now looking less likely , the Warriors remain in pursuit.

There has also been some speculation that James could opt to return to the Cleveland Cavaliers to potentially close out his career with his hometown team, where he played the first seven years of his career and won his third NBA title in 2016. The Cavs reportedly have interest in a second reunion with James, according to insider Chris Haynes . James is the Cavs’ all-time leader in points (23, 119), rebounds (6,190), assists (6,228) and steals (1,376).

Earlier this week, Cavs star James Harden declined his $42.3 million player option to work on a new, multi-year contract.

The Warriors are current favorites to land James in free agency with -500 odds per DraftKings , with the Cavaliers at +300, Heat at +1000 and Spurs at +2000.
