Major League Baseball (MLB) has 2,430 regular-season games scheduled for 2027, based on its standard format of 30 teams playing 162 games apiece. The final number could be lower, however, if games are canceled or a potential lockout disrupts the season.
That uncertainty is the focus of a market on Kalshi, where traders can take positions on how many MLB regular-season games will actually be played.
Here's how the schedule works and what the market rules mean.
2,430 MLB Games Scheduled for 2027
Each of MLB's 30 teams is scheduled to play 162 regular season games; since every matchup involves 2 teams, the calculation is:
30 teams x 162 games ÷ 2 = 2,430
MLB has already released its 2027 schedule, with the regular season set to begin on March 24 with an Opening Night game, followed by traditional Opening Day on March 25. The final day is scheduled for September 26.
How Does Kalshi's 2027 MLB Games Market Work?
Prediction market apps
like Kalshi list a series of contracts under Pro Baseball: Games Played in the 2027 Season. Instead of asking traders to predict one exact final total, it offers separate Yes or No markets based on thresholds.
These include whether the season will feature:
- More than 600 games
- More than 1,215 games
- More than 1,930 games
- More than 2,425 games
- No games
The “More than 2,425 games” contract, for example, resolves Yes if the number of MLB regular-season games played exceeds 2,425. With 2,430 on the schedule, that threshold allows for only four or fewer games not to be played. The market's outcome is verified using the governing league.
What Could Reduce the 2027 MLB Game Total?
The most foreseeable risk is cancellations. Bad weather can postpone games, while scheduling complications may make some fixtures difficult to rearrange before the regular season ends.
A Labor Dispute Between Owners and Players Could Reduce the Total
A wider disruption could have a much bigger impact. In fact, the biggest threat to MLB's 2,430-game schedule is a potential labor dispute between team owners and the MLB Players Association (MLBPA).
The current collective bargaining agreement (CBA) expires on December 1, 2026. If the two sides fail to agree on a replacement, owners are expected to lock out the players, potentially disrupting the 2027 season.
The main sticking point is a proposed salary cap. MLB’s latest proposal sets a $258.2 million cap and a $180.2 million payroll floor, starting in 2028. The MLB Players Association opposes a cap because it would limit player earnings.
The last dispute, the 99-day lockout of 2021-22, pushed Opening Day back a week, but the postponed games were rescheduled and teams still played all 162. That precedent matters here: a lockout only lowers the total if games are canceled outright.
A longer stoppage that forces cancellations would put the 2,425-game threshold at risk, since it allows only four missed games.
What Are Kalshi Traders Predicting?
The latest trading snapshot as of November 5 gives More than 600 games an implied probability of about 84%, falling to 74% for More than 1,215 games, 58% for More than 1,930 games and 36% for More than 2,425 games.
These figures indicate that traders currently consider a season with at least 600 games as highly likely, but are less certain that MLB will complete almost the entire 2,430-game schedule.
