On Monday, June 22, the Boston Celtics lead the race on both platforms. Kalshi traders give Boston a 57% chance of landing Giannis, while Polymarket traders price the Celtics at 55%. The Miami Heat sit in second place at 39% on Kalshi and 38% on Polymarket.

Celtics Take Control of the Market
Boston strengthens its position heading into draft day after ESPN’s Brian Windhorst reports that the Celtics are “all in” on pursuing Giannis Antetokounmpo and would consider including Jaylen Brown in a potential trade package.
That report gives traders a concrete framework for how Boston could acquire the two-time MVP and fuels the Celtics’ rise across prediction markets. Unlike many rumors that lack a realistic path to completion, Windhorst’s reporting signals that Boston puts one of its core stars on the table to get a deal done.
The Celtics also hold additional draft capital and roster flexibility that could help Milwaukee accelerate a rebuild around younger talent. As a result, traders continue to buy Celtics positions ahead of Tuesday’s draft.
With volatility expected to spike around draft night, traders who agree with Boston’s momentum can use the Kalshi promo code ACTION for a $10 bonus or the Polymarket promo code ACTION for a $50 bonus to enter positions before the market potentially moves too quickly to chase.
Heat Continue to Apply Pressure
Miami still commands significant support despite Boston’s surge.
Reports continue to link Giannis to the Heat, and many traders believe Miami remains his preferred destination. A partnership with Bam Adebayo would immediately create one of the NBA’s most dangerous frontcourts and give the Heat another path back into championship contention.
Miami has also reportedly assembled a substantial trade package. According to NBA insider Mark Stein, the Heat would consider including Tyler Herro, Kel’el Ware, Jaime Jaquez Jr., and the No. 13 overall pick in a deal for Antetokounmpo. That package includes three recent first-round selections and a pick just outside the top 10, allowing Milwaukee to add both young talent and future upside.
The willingness to move that level of talent helps explain why Miami continues to hold nearly 40% of the market on both Kalshi and Polymarket. However, traders currently appear to believe Boston’s willingness to discuss Jaylen Brown gives the Celtics a slight edge heading into draft week.
Miami still offers an alternative path for traders who believe the market has overreacted to Boston’s rise. Use the Kalshi referral code ACTION for a $10 bonus or the Polymarket referral code ACTION for a $50 bonus to take Heat positions ahead of what could become a fast-moving draft-night market.
Draft Day Could Shake Up the Odds
The NBA Draft often sparks blockbuster trades, and traders expect this year’s event to trigger major movement in Giannis markets.
If Milwaukee receives a compelling offer, traders push one team sharply higher within minutes. If the Bucks fail to reach an agreement, traders increase positions tied to Giannis remaining in Milwaukee.
With many around the league expecting trade activity to materialize by or during the NBA Draft, traders move quickly to position themselves ahead of potential announcements. Claiming the Kalshi $10 bonus or Polymarket $50 bonus now allows new users to enter the market with one of the best prediction market promos.
For now, the market tells a clear story. Boston and Miami dominate the board, while every other team trails far behind.
