Payer Overview

Oscar Health Inc Grp is a nationally recognized health insurer focused on retail individual and small-group markets, operating as the #22 largest US A&H payer by premium. The company reports $8.78B in US premium and holds a 0.61% US market share across 18 states, serving an Estimated Total Members base of 1.16M through 12 affiliated subsidiaries.

Oscar Health Inc Grp does not hold a #1 position in any individual state. The insurer’s footprint is concentrated in a subset of states, with premium and membership clustered in key Southeast and Sun Belt markets, which shapes its negotiating leverage with regional provider systems and national multi-state groups.

Premium by Scope

Oscar Health Inc Grp's premium is exclusively reported in the US States & DC scope, representing the entire disclosed premium footprint. This concentration implies provider negotiations and network strategies should focus on US state-level contracting dynamics rather than territorial or foreign exposure. For provider groups evaluating Oscar Health Inc Grp, the lack of territory or foreign premium simplifies market access planning and suggests resources should be allocated to state teams in the primary footprint.

Oscar Health Inc Grp shows heavy concentration in Florida and Georgia, with $4.84B and $1.85B in premium respectively, together accounting for the majority of the carrier's reported premium. The national footprint spans 18 states, but premium outside the top two states is dispersed in much smaller pools (most under $200M), which limits broad negotiating leverage with large national health systems. For provider contracting, this means Oscar Health Inc Grp will likely have the most influence in state markets where it carries >$1B in premium, while multi-state provider groups should prioritize localized contracting strategies in smaller states where Oscar’s share and premium are modest.

State-by-State Market Position

Oscar Health Inc Grp’s strongest presence is in the Southeast and Sun Belt, anchored by Florida and Georgia where the insurer writes $4.84B and $1.85B in premium respectively. The Midwest and Northeast exposures are present but fragmented: states like Ohio, New Jersey, and New York show mid-tier premium pools between $115M and $455M, while many other states register single-digit to low-double-digit millions in premium.

This geographic distribution suggests Oscar Health Inc Grp is a regionally concentrated competitor rather than a uniformly national one. Multi-state provider groups should expect substantive negotiation weight in Florida and Georgia and tactical, state-level discussions elsewhere. For national health systems seeking scale, Oscar’s concentrated footprint means its impact will be greatest where premium and estimated members — 549K in Florida and 308K in Georgia — are largest.

Estimated Member Demographics

OSCAR HEALTH INC GRP is estimated to cover 1,162,084 members nationally based on Census × NAIC share calculations. The age distribution is as follows:

The largest age bands are 55-64 (174,182 members), 45-54 (169,916 members), and 35-44 (167,930 members), indicating a strong adult presence. The pediatric population (under 18) is also substantial, with over 237,000 members.

This age profile suggests that OSCAR HEALTH INC GRP's insured population will drive demand for both adult chronic care and pediatric services. Providers should expect a balanced mix of preventive, acute, and chronic care needs, with a moderate senior segment requiring age-related care management.

Estimated Members by State

OSCAR HEALTH INC GRP's member distribution is highly concentrated in Florida (549,522 members) and Georgia (307,663 members), which together account for over 70% of the payer's national membership. Other states with notable member counts include Texas (88,536), Ohio (61,904), and Tennessee (23,930). The remaining states have significantly smaller member populations, with most under 25,000 members each.

This geographic concentration does not always align with market share rank. For example, Florida and Georgia have high member counts and relatively high market shares, but Texas, despite a lower market share, still has a large member base due to its population size. States like Virginia and Michigan have minimal member presence, reflecting both low market share and smaller populations.

For providers, this means that OSCAR HEALTH INC GRP is a major payer in the Southeast, especially in Florida and Georgia. Multi-state provider groups should prioritize contracting and care delivery strategies in these states, as they represent the bulk of OSCAR's insured population. States with smaller member counts may require less focus, but still offer opportunities for niche engagement, especially in urban centers or specific age bands.
