Polymarket Promo Code WSN: $50 Bonus for Sun vs. Mystics (September 22)

Polymarket Promo Code for Tuesday, September 22, 2026

Below is a snapshot of the active promotional terms available for new users entering prediction market positions on today's WNBA schedule.

Featured Matchup: Sun vs. Mystics

The Washington Mystics (26-16) enter this regular-season contest carrying strong momentum as they prepare for the upcoming postseason. Washington has been led in the paint by strong performances from rookie standout Kiki Iriafen and veteran forward Michaela Onyenwere, while point guard Georgia Amoore continues to orchestrate their perimeter shooting. Over their past 10 games, Washington’s offense has surged to an average of 89.7 points per game, benefiting from elevated execution beyond the arc.

On the other side, the Connecticut Sun (10-32) look to break out of a five-game slide during their final road game of the season. Connecticut continues to rely on interior contributions from Brittney Griner and defensive presence from Olivia Nelson-Ododa and Aaliyah Edwards. However, allowing 91.9 points per contest over their last 10 games has created uphill battles for the roster.

When these teams last met in July 2026, Washington pulled away for a 92-84 victory at CareFirst Arena.
