Oscar Health
The business, the turning points, and the decisions behind them.
01 / WHAT IT BUILT
What the company did
Oscar Health is a US technology-driven health insurer founded in 2012, selling individual and family health plans — largely through ACA marketplaces — with a tech-first member experience. It listed on the NYSE (OSCR) in 2021 at a valuation of about $7.7 billion, grew to roughly 2 million members, and reported $11.7 billion in revenue for 2025.
02 / Oscar Health FAILURE REASONS
Failure reasons
In 2025 healthcare costs outran Oscar's technology savings. The medical loss ratio worsened to 87.4% from 81.7% in 2024, driven by higher morbidity and risk-adjustment accruals, while SG&A reached $2.0 billion. Operating earnings of $57.3M in 2024 swung to a $396.4M operating loss; net income of $25.4M became a $443.2M net loss. Management called 2025 a reset year and targeted 2026 profitability, with the expiration of enhanced premium tax credits looming as a further headwind.
