The tribe operates its own housing authority and issues
tribal vehicle tags. They own two gas stations, two smoke shops, two financial services companies, and five casinos. The estimated annual economic impact of the Otoe–Missouria Tribe is $156.30 million. The Otoe–Missouria casinos are 7 Clans Paradise Casino in Red Rock; First Council Casino in
Newkirk, and Lil' Bit of Paradise Casino—Chilocco, also in Newkirk; and Lil' Bit of Paradise Casino—Red Rock, in Red Rock. A new casino was opened in May 2016 in Perry, Oklahoma. The tribe also jointly operates a wind farm along with other tribes. On May 20, 2019, the
National Credit Union Administration presented a federal credit union charter to the Otoe-Missouria Federal Credit Union in
Red Rock, Oklahoma. The Otoe-Missouria Federal Credit Union will serve approximately 4,200 citizens and employees of the Otoe-Missouria Tribe. The Taylor Policy Group concluded that the tribe's efforts to diversify its economy resulted in a massive economic impact to Oklahoma and surrounding areas, including over $45 million in direct compensation to employees across the Tribe's various enterprises.
Predatory payday lending In 2010, the tribe partnered with
Mark E. Curry to create a high-interest
payday loan company, American Web Loan, initially using its sovereign status as a defense against state
usury laws until that argument was rejected in court challenges. By 2014, American Web Loan was one of the largest payday lenders in the United States, with a typical annual interest rate of around 700 percent on loans it provided. The tribe paid for the company by taking out loans in that amount from Curry and one of his companies, and a federal judge ruled in 2019 that Curry had continued to maintain control. In 2022, another company that had paid the Otoe-Missouria tribe to use its tribal sovereignty to claim exemption from state usury laws paid $44 million to settle a lawsuit for lending at illegally high interest rates. ==Language and culture==
