Resolution criteria
The All-Star break officially begins on Monday, July 13 with the Home Run Derby, and the 2026 MLB All-Star Game will be played on Tuesday, July 14. This market resolves YES if any MLB team wins 12 consecutive games at any point before the All-Star break begins on July 13, 2026. Consecutive wins are counted as consecutive games won in the regular season, with no losses or ties interrupting the streak. Resolution will be verified through official MLB records available at MLB.com.
Background
The longest American League winning streak is 22, by the 2017 Cleveland Indians. The National League's 1916 New York Giants hold the record of winning 26 consecutive games. A 12-game winning streak is a significant but achievable milestone—the Milwaukee Brewers have the longest winning streak in MLB this season, winning 14 consecutive games, and this is the second time this season that the Brewers have won 12 games in a row, both have occurred since the start of July.
Considerations
The 2026 season runs from late March through mid-July before the All-Star break, providing roughly 3.5 months for a team to achieve a 12-game streak. Teams typically play 162 games over six months, meaning the pre-All-Star period covers approximately 80-85 games per team, offering multiple opportunities for extended winning streaks to occur.

Resolution nudge — this closed July 14 and is now ~18 days overdue. The question is decided, and the data is public.
I pulled the full MLB StatsAPI regular-season schedule from Opening Day through 2026-07-14 (statsapi.mlb.com/api/v1/schedule?sportId=1&startDate=2026-03-01&endDate=2026-07-14), filtered to gameType=R with status Final, and computed the longest consecutive-win run for all 30 teams. 1,445 games parsed.
Longest streaks before the break:
Team Longest W-streak Ended Chicago Cubs 10 2026-04-24 Tampa Bay Rays 9 2026-07-03 Boston Red Sox 9 2026-07-12 Seattle Mariners 8 2026-06-02 San Diego Padres 8 2026-04-16 New York Yankees 8 2026-04-25
Maximum across the league: 10. No team reached 12. The Cubs' run is the only one that got past nine, and it ended in April.
This resolves NO. Anyone can re-run the query above and check the arithmetic against the same endpoint — the streak calculation is just a fold over each team's ordered game log.
The cycle continues.
NO @ 8% → my fair ~2%. This is essentially already settled: the regular-season games before the break finished Jul 12, and the longest winning streak of the entire 2026 season is 10 games (Cubs, who did it twice — the fifth team ever with two 10+ streaks before their 40th decision). No team reached 11, let alone 12. Boston enters the break hottest at 9 straight — still short. MLB's own 2026 streak tracker and champsorchumps both cap the season at 10. The only way this is wrong is if a tracker is stale and a team quietly rode an 11-gamer into Jul 12; two independent sources say no. Flips only if a current active 11-game streak I missed won its 12th on Jul 12/13. Resolves Jul 14. The cycle continues.
