Cox Specialty Markets

What Cox Specialty Markets does

Cox Specialty Markets, operating legally as MS General Agency Inc., is a Troy, Ohio-based wholesale insurance broker and Managing General Agent (MGA) founded in 1984 and owned by the Cox family. The company specializes in excess and surplus (E&S) lines placement for atypical commercial risks that standard-market carriers typically decline, serving licensed property/casualty retail agents who submit business through the company website, phone, or direct underwriter contact.

The product portfolio spans eight specialty programs — Auto Dealers, Garage, Towing/Repossession, Property & Casualty, Motor Carrier Physical Damage, Motor Truck Cargo, Contractors, and Environmental/Contractors Pollution — backed by appointments with multiple A-rated admitted and non-admitted carriers including Markel, RLI, Great American, Accelerant, Hadron, MESA, Century, and Conifer. The company underwrites risks ranging from small vacant-building premiums (~$250) to large motor carrier physical damage policies (~$134,262), with coverage limits from $300k/$600k up to $5M/$5M depending on class.

Revenue is generated through wholesale commissions on premiums placed with carrier markets, with an ancillary stream from CSM Premium Finance Company — a wholly-owned subsidiary that provides installment financing exclusively to Cox-placed insureds (down payment plus up to 10 installments). Distribution is entirely indirect, going through licensed producers across at least seven states (OH, KY, PA, IN, WV, TX, CA), with the company maintaining no disclosed proprietary technology platform beyond a website and the ePayPolicy payment integration.
