However, significant consolidation was observed in major states like California, which dropped by 44 plans (-9% YoY), and New York, down by 36 plans (-13% YoY).

These trends suggest a growing divergence in plan availability across states, with some regions consolidating and others expanding to meet demand.

At the national level in 2025, Florida is leading the way with 591 total plans and 64 new plans, followed by California (421, 52), Texas (385, 55), Pennsylvania (316, 54) and New York (236, 26). Along with leading states, Georgia, Illinois, and Washington are witnessing a surge in new plans, with Georgia showing 37 new additions, Illinois and Washington at 35.
The distribution of plan categories across states reveals that Renewal Plans continue to dominate, reflecting national trends. Even in Consolidated Renewal Plans, the leading states are California (45), Florida (22), and Pennsylvania (17), while six states have no such plans. Texas (54), Ohio (33), and Florida (28) top the list for Renewal Plans with SAE, although four states have none. Texas (48), Indiana (41), and North Carolina (38) also show strong numbers for Renewal Plans with SAR, while Hawaii does not have any SAR plans. Initial Contracts are concentrated in Indiana, which has 11 plans, with Georgia, North Carolina, and Missouri each having 8.
Smaller states, like Vermont and Wyoming, exhibit minimal growth. Wyoming holds steady with 20 total plans despite no new additions, and Vermont with only eight plans—the fewest among all states—includes just a single New Plan. These variations reflect diverse strategic priorities across regions.
