Giannis Antetokounmpo is the biggest domino that could fall this NBA offseason.

The Bucks’ star has already been the subject of trade rumors despite the NBA Finals not yet starting.

DraftKings’ oddsmakers have a new betting market up with money already flowing in on a potential trade, although the two-time MVP is still expected to start the season in Milwaukee (-140 odds, 58.33 percent implied).

The Spurs are the most likely team to acquire the Greek Freak, with +380 odds (20.83 percent implied likelihood).

A duo of Antetokounmpo and Victor Wembanyama would be scary and form perhaps the best defensive big man pairing in league history.

Antetokounmpo is a former Defensive Player of the Year, while Wembanyama was a massive favorite to win the award last year before being shut down due to a blood clot issue.

There surely will be a massive market for Antetokounmpo if the Bucks opt to field offers for him.

The Spurs are followed by the Rockets (+450), Raptors (+800), Mavericks (12/1) and Thunder (13/1).

The Knicks, whom some fans had hoped would be in the market, are thought of as long shots to acquire him, coming in at 16/1 odds.

The Post’s Brian Lewis reported that the Nets were hoarding draft capital with Antetokounmpo in mind, but DraftKings views that as a 20/1 long shot.

The NBA hot stove will really tip off when the NBA Finals complete and the new league year officially begins July 1.
