McIlroy, part of the headline group with world number one, Scottie Scheffler and Xander Schauffele, had the chance to equal the lead on the 17th but missed his birdie shot by inches.
However, he held his nerve on the final hole to finish a bogey-free five-under 65, giving him a share of the lead with Cantlay.
A tough round for Scheffler saw him card a one-over 71, while Schauffele missed his birdie putt on the final hole to finish on level par.
Five-time major winner Brooks Koepka briefly led after 10 holes, but a sloppy finish saw him finish on level par, with Collin Morikawa matching his score shortly after.
Meanwhile, Tiger Woods made a promising start with a birdie on the 10th, his first hole of the round, but he struggled as he went on, finishing with a four-over 74.
Bryson DeChambeau was among the later starters in North Carolina.
