2026 college basketball rankings, updated AP Top 25 after Week 15

Michigan is the new No. 1 in the latest AP Top 25 poll released Monday. The Wolverines haven’t sat at the top spot in 13 years, and they got there in a big way, pulling 60 of 61 first-place votes with a 24-1 record.

Arizona is the reason that door opened. The Wildcats came into last week unbeaten and left it with two losses, dropping at Kansas and then at home against Texas Tech.

Houston jumped to No. 2 and grabbed that last first-place vote, with Duke sliding into third.
