Company Overview

Oscar Health, Inc. is a U.S.-based health insurance and healthcare technology company focused on providing individual, family, Medicare Advantage, and small group health plans. The company operates primarily within the health insurance and digital healthcare industries, with an emphasis on technology-enabled member engagement, virtual care access, and data-driven healthcare management. Oscar generates most of its revenue from premiums earned through health insurance policies offered on the Affordable Care Act (ACA) exchanges, Medicare Advantage plans, and employer-sponsored coverage products.

Oscar differentiates itself through a consumer-oriented digital platform designed to simplify health insurance navigation, telemedicine access, claims processing, and care coordination. Its strategy centers on integrating insurance operations with proprietary technology tools intended to improve member experience and medical cost management. Founded in 2012 by Mario Schlosser, Joshua Kushner, and Kevin Nazemi, the company initially focused on ACA marketplace plans in select U.S. states before expanding into additional insurance products and technology-enabled healthcare services. Oscar became a publicly traded company on the New York Stock Exchange in 2021 under the ticker OSCR.

Business Operations

Oscar conducts its operations primarily through its insurance subsidiaries and technology-focused healthcare services platforms. Its core operating areas include Individual & Family Plans, Medicare Advantage, and Small Group Products. Revenue is generated primarily through insurance premiums, while additional revenue streams include policy administration and healthcare technology-related services. The company also operates technology infrastructure supporting member engagement, telehealth integration, provider search functionality, and clinical care navigation.

The company’s operations are concentrated in the United States, with participation in multiple ACA marketplace states and selected metropolitan regions. Oscar relies on a combination of proprietary software systems, provider network relationships, and care management capabilities to administer plans and manage healthcare utilization. Key subsidiaries include Oscar Insurance Corporation and Oscar Management Corporation. Oscar has also maintained strategic relationships with healthcare providers and technology partners to support network expansion and virtual care offerings. Public filings indicate collaboration arrangements with health systems and provider organizations aimed at improving coordinated care delivery and member retention.

Strategic Position & Investments

Oscar’s strategic direction has focused on scaling membership growth while improving medical loss ratios and operational efficiency through technology automation and data analytics. The company has invested heavily in digital member tools, virtual care integration, and risk-adjustment capabilities intended to support profitability in ACA and Medicare markets. Management has consistently emphasized technology-enabled healthcare navigation as a core competitive differentiator relative to traditional insurers.

Oscar has pursued expansion through both organic market entry and strategic investments in healthcare technology capabilities. The company previously developed and operated the +Oscar platform, which provided technology and administrative services to health system partners and payors. Oscar has also invested in clinical engagement tools and data infrastructure to improve underwriting, member acquisition, and care coordination functions. Public disclosures identify continued emphasis on expanding presence in high-growth ACA markets while balancing regulatory compliance, pricing discipline, and capital management.

Geographic Footprint

Oscar’s operations are concentrated entirely within the United States, where it offers insurance products across multiple states through ACA marketplaces and Medicare Advantage programs. The company is headquartered in New York, New York, and maintains operational and administrative functions supporting insurance, technology development, customer service, and care navigation activities. Its market presence has historically included states such as Texas, Florida, California, New York, and several other ACA exchange markets, although participation levels vary by year based on regulatory and market conditions.

The company does not maintain a significant direct international operating presence. Its geographic strategy has instead focused on selective expansion within U.S. insurance markets where management believes consumer adoption, provider partnerships, and regulatory conditions support long-term growth. Oscar’s influence outside the United States is limited primarily to investor participation and capital markets exposure rather than direct operational activity.
