Why More Small and Mid-Size Employers Are Turning to Stop-Loss Captives

AUGUST 4, 2026

As healthcare costs continue to rise faster than inflation, fully insured health plans will continue to see premium increases at renewal. Larger employers with more predictable claims may find savings by moving to a self-funded health plan, but smaller employers often lack the claims volume or financial stability to take on that risk alone. Captive arrangements offer a middle ground, giving organizations with 50 to 200 employees a way to access the benefits of self-funding while reducing the risk.

How Do Employers Benefit From a Captive?

Captives allow multiple employers to access the savings potential and stability of self-funding by pooling their risk. Each employer pays for their health plan claims up to a defined amount, while stop-loss coverage protects against catastrophic or unpredictable claims.

The captive sits between the employer's retention and the stop-loss carrier, covering a portion of larger claims before higher-level coverage begins. Because large losses are spread across the group, employers benefit from more stable pricing.

Many captives are also structured to return surplus to employer members when claims costs are lower than expected. With recent renewal pressures, participation has steadily increased, helping captives move from a niche solution to a more mainstream strategy for smaller employers.

Why Captives Are Gaining Ground

What makes captives increasingly attractive is not just the funding structure, but the level of control and transparency it can give employers:

Underwriting and Plan Pricing. For smaller groups, fully insured pricing relies heavily on the combined averages of many employers, with pooling charges to cover high-cost claims across the carrier’s entire book of business.

With a captive, employers pay based on their own claims experience, only pooling with other members of the captive to cover their catastrophic risk. This focus on individual claims history, paired with a narrowed risk-sharing group, is what helps drive lower costs for employers within a captive arrangement.

Cost-Containment Programs. Captives often incentivize employers to keep claims expense low by offering cost management programs and other tools typically reserved for larger groups. These may include:

• Case management for the coordination of high-cost, complex medical claims
• Utilization review to evaluate whether healthcare services are medically necessary and appropriate
• Population health solutions to help employers proactively manage risk and improve health outcomes

Together, these programs can reduce the impact of claims on overall plan spending. Keeping claims costs low also improves the likelihood of a surplus return for all the members of the captive.

Insights Into Cost Drivers. Captives also give employer members direct access to their own claims data — something employers may not get with a fully insured plan. With greater visibility into health plan spending, employers can identify cost drivers and take steps to improve health outcomes while optimizing plan performance.
