Oscar Health, Inc.

The venture-backed, technology-first health insurer that bet its existence on the Affordable Care Act's individual exchanges. Oscar spent a decade losing money, went public in 2021 at ~$7.9bn and lost most of that value, then under Mark Bertolini became the largest ACA-focused insurtech and the first of its cohort to post an annual profit (2024). It was knocked back into loss by the 2025 exchange morbidity shock and returned to strong profit in the first half of 2026 (verify).
