Why Fortune 500 Companies Use Captives, and Why Real Estate Is Catching Up

Captive insurance is not new. It is not a startup idea or a loophole. It is one of the oldest tools in corporate risk management, and the biggest companies in the country rely on it.

According to the National Association of Insurance Commissioners (NAIC), approximately 90% of Fortune 500 companies have captive subsidiaries. So the real question is not whether captives work for Fortune 500 companies. It is why real estate owners, who spend heavily on insurance every year, were left out for so long, and why that is changing.

What a captive is, in one paragraph

A captive is an insurance company owned by the businesses it insures. The NAIC describes it as essentially a form of self-insurance that operates like a commercial insurer and follows state rules on reporting, capital and reserves. Practically any risk a commercial carrier writes can be written by a captive.

Why the largest companies use captives

• They stop paying for someone else’s profit. When premiums go to a carrier, whatever isn’t spent on claims and expenses becomes the carrier’s underwriting profit. In a captive, that result belongs to the owners.

• They get coverage built for their risk. A captive can write terms that fit the business instead of a one-size form.

• They reach the reinsurance market. Captives can buy reinsurance directly to protect against large losses.

• They control claims and data. Owners see their own loss data and decide how claims are handled.

The scale is significant. The Captive Insurance Companies Association notes that market studies found more than $100 billion in premium written through U.S.-domiciled captives in 2022.

Why real estate waited

Ownership is spread out

A Fortune 500 company buys insurance as one organization. A real estate portfolio is usually split across many LLCs, partnerships, lenders and states, each with its own requirements. Pooling that premium takes infrastructure that was not built for real estate until recently.

Going it alone is expensive

Forming your own single-parent captive means capital, a domicile, actuaries, a captive manager and ongoing compliance. That made sense for the largest corporations and kept most real estate owners out.

Nobody walked owners through it

Most owners buy insurance the way the market taught them: through a broker, from a carrier, renewed every year. Brokers are usually paid a commission on the premium they place, and that model doesn’t naturally lead to a conversation about owning the insurer. Owners didn’t miss something obvious. The option simply was not put in front of them.

What changed

Costs forced the question

The average apartment unit cost $68.39 a month to insure in 2024, up from $38.74 in 2019 in inflation-adjusted dollars, according to a Federal Reserve analysis of Trepp data. When insurance becomes one of your fastest-growing expenses, you start asking where the money goes. For more, see why multifamily insurance costs rose.

Shared structures arrived

Group captives, risk retention groups and cell structures let many owners share one insurance company’s infrastructure while keeping their own results separate. That removes the need to build a captive from scratch.

Where Insur3Tech fits

Insur3Tech’s captive brings the Fortune 500 model to real estate owners and operators. There is no minimum premium and no unit minimum; portfolios as small as 4 doors can join. There are no holdout periods. The entire program is reinsured, so you carry no downside risk. What isn’t spent on claims comes back to you. We insure 100,000+ doors across every portfolio size and asset type.

The shift is from being a customer of an insurance company to owning one yourself. The largest companies made that move decades ago.
