The Aces started the season by splitting a two game set in Seattle in a rematch of last year's finals. After that set, they won four of their remaining five games in May, with their only other loss coming against Connecticut. They lost their opening game in June, but went on a five game winning streak from there. The streak was snapped in Minnesota, in overtime, in a one point loss to the Lynx. The Aces followed the loss with an overtime win against Seattle to finish out June 7–2. They carried their winning streak into July, winning the first two games of July. The streak was snapped, again in overtime, by the Mercury. They rounded out July with a loss and a win to finish 3–2 in the month. The Aces went into the Olympic break with a 15–6 overall record. They returned from the break with a 4–1 record in August, with the loss to the Sun surrounded by two wins. They closed out the season with a 5–1 record in September, including a four game winning streak. They finished the season with a 24–8 overall record, which earned the team the second seed in the 2021 WNBA Playoffs. 24 wins tied their franchise record for regular season wins with 2008.

As the second seed, the Aces earned a double bye into the Semifinals, and awaited the highest remaining seed from the Second Round. After the games of the First and Second Round, the highest remaining seed was the Phoenix Mercury. The Aces had home court advantage in the series, but lost two of their home games, despite a 13–3 home record in the regular season. The Aces couldn't win Game 5 at home, losing by three to end the series and their season.
