We are halfway through the MLS regular season, and although the grand finale is still a ways away, traders are already predicting which team will lift the Philip F. Anschutz Trophy.
The "MLS Cup Winner 2026" market, which opened on Polymarket on February 17, has already amassed a volume of nearly $17 million. This total is expected to increase significantly, as the settlement date of December 18 is still nearly seven months away.
Who Will Win the 2026 MLS Cup?
What the Odds are Saying
Inter Miami, according to Polymarket traders, is the frontrunner to win the MLS Cup and is closely followed by the Vancouver Whitecaps and Los Angeles FC. The market reflects an established hierarchy within the league, favoring star power and not just the positions in the table, which explains why Los Angeles FC appears as a strong contender. Despite struggling to stay among the top seven of the Western Conference, their talented squad has earned the trust of many traders.
Though the team led by Lionel Messi is the defending champ, much can change on the road to the coronation day. Tadeo Allende’s knee surgery was a blow to the squad’s depth, as the striker, who had a fantastic 2025 season, may be ineligible for several months. Still, the market sentiment toward Inter Miami remains largely positive as traders believe the team can become the first since 2012 to win back-to-back titles.
For those seeking profitable longshots, teams such as the San Jose Earthquakes and Chicago Fire are great buys. Despite having strong regular seasons, their current “Yes�� share prices are still on the lower side. These positions appeal both to traders who love underdog narratives and those looking for contracts with significant potential for appreciation as the playoffs approach.
Keep an Eye Out For …
The FIFA World Cup will be a key event for MLS traders to monitor. As the premier soccer tournament, it can offer insights into the future plans of veteran players. For example, Argentina’s performance could influence Lionel Messi’s decisions regarding the conclusion of his career. Although Messi is currently under contract with Inter Miami through the end of the 2028 season, things may shake up after the World Cup. Without Messi, Inter Miami’s chances of winning the MLS would be significantly reduced.
Another significant development that will surely have an impact on this market is the MLS Secondary Transfer Window, which opens on Monday, July 13, and will close on Wednesday, September 2. The summer transfer window was significantly extended to match the schedules of major international leagues. For the first time in decades, the window will run deep into September, allowing teams to acquire high-quality talent right before the playoffs.
The Secondary Transfer Window may shake up things in the MLS as some big names will be a part of the conversation. For instance, Bernardo Silva and Robert Lewandowski are two of the biggest stars who have reached the end of their respective contracts and will be open to negotiation after the World Cup. In the case of the Polish striker, the Chicago Fire are among the frontrunners courting the veteran. The incorporation of such a lethal attacker could most definitely affect the market sentiment.
The structure of the Major League Soccer is grueling, combining a long regular season followed by a sprint through a single-elimination playoff format. That means that the eventual champion will need both endurance and expertise in knockout games.
The teams are subject to drastic changes like injuries, the acquisition of top players, and overall changes in performance. Prediction markets react almost instantaneously to those shifts, so we can expect some movement in the next few weeks. As contracts are tradeable assets at any point before the settlement, there is room for strategic investments from traders.
