IB model of American futures companies refers to the system in which securities companies introduce investors to futures companies and provide certain services for investors to carry out futures trading, so futures companies pay commissions to securities companies. IB model was originally used in grain warehouse to serve farmers and also provide hedge transactions for farmers. The IB model builds the business cooperation relationship between brokers and futures companies, and futures companies will take the initiative to brokers.

Because securities companies prefer to hold shares in futures companies rather than participate in shares, some investors will be unwilling to lose their controlling shares and have no intention of reorganizing securities companies, and will choose to re-register for self-management or asset management, thus not relying on the marketing channels and resources of securities companies.
