The 2026 Michigan Bottom Half Class Championships take place on October 10–11, 2026 at Wyndham Garden Ann Arbor in Ann Arbor, Michigan. The Michigan Chess Association runs a multi-section weekend championship with five-round two-day sections and two shorter one-day lower-rating groups.

The main sections use G/90 + 30-second increment. The Top section is also FIDE rated, while the U900/Unrated and U500/Unrated one-day events use G/30 with a five-second delay.

The organizer guarantees $2,575 in cash prizes for the two-day sections. In addition, trophies and state-champion recognition reward leading Michigan residents and winners in the lower-rated groups.
