IHSA 2026 playoff outlook: The 39 unbeaten teams in Illinois high school football after Week 6

The Illinois High School Association this week released its third 2026 playoff outlook , which at this point still includes every team in the state separated by hypothetical class and ranked by won-lost record.

The weekly list works only as a guide to the playoffs and is not a prediction of the final classes and seeds, although its usefulness as a postseason roadmap grows each week.

Below are the 39 remaining unbeaten teams. They are among the 202 teams listed here who have clinched a playoff berth, with 4-plus wins in each of the eight classes, with playoff points earned, along with the enrollment range of each class, which are subject to change based on which teams qualify for the 384-team playoffs.
