Two world records were broken at the 2018 NCAA Indoor Athletics Championships:
Men's 400m: Michael Norman, University of Southern California 44.52
Men's 4 x 400m: Texas A&M University 3:01.39*
* In this race the University of Southern California actually had a faster time (3:00.77) but world records can only be awarded if all runners are from the same nation - USC had a runner from Antiqua and 3 Americans.
