AEP 2026 reshuffled the MA market. While membership is down 1.2% from Dec 2025, the changes in markets that carriers are choosing to focus on are opening up real selling opportunities this year.

States with the most change

NC, TX, OK, TN, and FL are the growth markets to watch by absolute member growth. WV, KS, and KY are also worth prioritizing: while their member volumes are smaller than others, their high percentage growth signals these markets are heating up.

Top 25 fastest-growing plans 

Many are in MN, NY, GA, and MI due to carrier exits and service area reductions in these states, forcing members to find new plans. If they’re not satisfied with their current plan, you may be able to help them make a change with one more month left in OEP.
