Wagering on fantasy sports and playing at DFS sites such as DraftKings, Monkey Knife Fight and FanDuel is perfectly legal in the state of Oklahoma in 2020. The Daily fantasy sports igaming market remains unregulated for now as there are still some legalities to straighten out. Oklahoma last tried in 2017 when a bill failed. It was shot down by the Tribes. Even when regulation comes, it won’t affect the OK daily fantasy players.
