This year’s AIME I was held on February 5th, 2026. Middle school and high school students who qualified through the AMC 10 and AMC 12 were able to compete. Congrats to everyone who participated!
The problems can now be discussed! See below for the answer key for the 2026 AIME I questions as well as the concepts tested on each problem. All answers for the AIME are in the form of 3-digit integers.
