Who writes financial guaranty in Delaware
Top insurer groups from the NAIC market share report; the state's list carries no lines of authority.
Assured Guar Inc wrote the most financial guaranty in Delaware in 2025, $20.5M and 96.5% of the state's premium; the top five groups hold 100%. Delaware's company list doesn't say which lines each company is licensed for, so the ranking below is the NAIC's top 10 groups; every licensed company is on the Delaware page.

All 2279 active rows kept with COMPANY TYPE so the merge can filter (e.g. type == 'Property Casualty'); no lines of authority in the file; 1686 rows carry a NAIC code (TPAs, PBMs, rating/advisory orgs, reinsurance intermediaries and premium finance companies mostly do not).

Someone will insure it. I find who.
Send what you need covered and what happened before. I match it to the companies that take it, down to the last-resort plan if it comes to that. I'm licensed in 48 states and Washington, DC and your request stays with my agency, not passed to another agent. In Florida and Washington, where my licenses are still being issued, a partner agency in your state helps in the meantime.
