GROUP 1001 INS HOLDINGS GRP Market Analysis: Market Share and Coverage by State

Payer Overview

GROUP 1001 INS HOLDINGS GRP is the #114 ranked US Accident & Health payer by premium and operates across 50 states. Its US premium footprint totals $456.05M, representing a 0.03% US market share and rolling up through 12 affiliated subsidiaries. The carrier reports an estimated 80.8K members nationally, with concentrated premium in several states that drive its national positioning.

The company's profile is focused on a broad, low-share national footprint rather than dominance in a handful of states; it does not hold a #1 position in any state. This distribution implies sourcing and contracting strategies that emphasize regional provider network relationships and selective, state-specific negotiations rather than a single national network play.

Premium by Scope

GROUP 1001 INS HOLDINGS GRP's premium is entirely within the US States & DC scope, with $456.05M reported in that channel and no recorded premiums in US territories or foreign jurisdictions. For providers assessing this payer, the concentration in the US mainland implies negotiations, credentialing, and network strategies should prioritize state-level dynamics and regional contracting teams. The absence of territory or foreign exposure simplifies compliance and reimbursement alignment to US state regulatory regimes.

GROUP 1001 INS HOLDINGS GRP shows a geographically broad but low-concentration premium footprint. The largest single-state premium is in CA at $129.10M, followed by IL at $52.83M and GA at $28.23M. Nationally reported premium sums to $456.05M and the carrier serves an estimated 80.8K members, so provider contracting teams should expect many states where the payer is a modest regional player rather than a market leader.

From a contracting perspective, the presence in higher-premium states like CA, IL, and GA suggests prioritizing negotiation resources in those markets where leverage and membership are greatest. In smaller states with sub-$1.00M premiums, operations and credentialing should be centralized to control overhead while still supporting local network access.

The Affordable Care Act (ACA) established federally-facilitated health insurance marketplaces ("exchanges") where individuals and small businesses can shop for and enroll in health plans, often with income-based subsidies. Issuers that participate in these marketplaces are required to report enrollment, claims, and denial data to CMS (Centers for Medicare & Medicaid Services) each year.

The sections below cover this payer's ACA marketplace-specific footprint — enrollment, plan portfolio, and claims/denial-rate data. This is a narrower, separate population from the NAIC-based commercial data shown earlier on this page (total premium, market share, and membership across all lines of business): ACA marketplace enrollment is typically a small fraction of a payer's total commercial book, and the two datasets should not be treated as equivalent. CMS claims-transparency reporting has also been inconsistent industry-wide since 2020 — many issuers have little or no data for 2021 onward, so a single reporting year is common and does not necessarily indicate anything about the payer's current ACA presence.

Estimated Member Demographics

GROUP 1001 INS HOLDINGS GRP is estimated to cover 60,073 members nationally, based on Census × NAIC share calculations. The age distribution is as follows:

The largest age band is 6-18, followed closely by the 35-44, 45-54, and 55-64 groups. This indicates a member base that is weighted toward families and working-age adults, with a smaller but meaningful senior population. Providers should expect a mix of pediatric, adult, and geriatric care needs, with utilization patterns reflecting preventive, chronic, and acute care across the age spectrum.
