Some Democrats want to repeal the insurance anti-trust exemption. Austin Frakt and Ian Crosby caution:

[I]nsurance companies are partially exempt from federal antitrust law for an important reason: so they can share rate-making data. This function actually benefits small insurers who would not otherwise have sufficient data to properly adjust premiums. Paradoxically, removing the legal cover for data sharing would harm small insurers more than large ones.
