Geography
Oscar operates in the United States and offered individual and family coverage in 18 states for the 2025 policy year, expanding to 20 states for 2026. Its business is shaped by state-by-state insurance regulation, local provider contracting and market selection, so geography directly affects product availability, pricing and network design.
Risks
Oscar's results depend on successful member acquisition, retention and market execution in a heavily regulated insurance business. Its model is exposed to ACA policy changes, state-by-state approval processes, medical cost trends, risk adjustment volatility, provider contracting complexity and legal or regulatory challenges around its affiliated medical group and distribution businesses.
