What is MLB World Series?
The World Series is Major League Baseball’s annual championship series, played between the American League and National League champions. The first team to win four games becomes the World Series champion. The series takes place after the league championship rounds and normally begins in late October. October 22 is shown as a planning reference for 2027 because it follows the opening-date pattern of the previous four editions. The official 2027 opening date, participating teams, game locations, and first-pitch times remain unannounced. The championship uses a best-of-seven format, with additional games played only when neither team has reached four wins.
How People Observe It
Fans watch the games on television or streaming services, follow live scores, attend games at the participating teams’ ballparks, and gather for viewing parties. The championship concludes when one team earns its fourth victory and receives the Commissioner’s Trophy.

The World Series follows the Wild Card Series, Division Series, and American League and National League Championship Series. Its final dates depend on MLB’s announced postseason schedule, while the number of games played depends on the results.
Previous years note
Recent World Series opening dates were October 27, 2023; October 25, 2024; October 24, 2025; and October 23, 2026. All four fell on a Friday. These dates establish a recent scheduling pattern but do not guarantee the same arrangement in 2027.
