FanDuel TV to shut down by November 2026, cutting over 100 jobs as network fails to align with strategy

FanDuel TV, the linear network that originated in 1999 as Television Games Network (TVG), is being phased out over the next 20 months. More than 100 jobs will be eliminated by the end of November 2026, FanDuel CEO Amy Howe announced during a company-wide meeting. The network will reduce its workforce by approximately 60% at the end of June after completing Keeneland and Triple Crown coverage commitments. FanDuel's account deposit wagering platforms will continue operating. FanDuel/TVG handled $2.239 billion through the Oregon Racing Commission hub in 2025, holding a 32.8% market share. The decision reflects FanDuel's strategic pivot towards sports betting, where it commands a 41% market share in the US. The network currently reaches approximately 30 million households, down from 50 million several years ago.

Missouri sportsbooks generate $53.3M revenue in second month as handle drops 29%

Missouri sportsbooks generated $53.3 million in gross revenue during January, their second month of operation, according to the Missouri Gaming Commission. FanDuel and DraftKings led operator performance. Handle dropped 29% from December's $543 million to $385.1 million, partly due to the Kansas City Chiefs missing the playoffs. Despite adjusted gross revenue of $19.3 million, the state collected only $137,900 in tax revenue as most operators carried forward December losses. Parlay wagers drove results, accounting for 60% of total volume and 67% of revenue with a 25.1% hold generating $35.6 million. DraftKings led with $22.8 million in January winnings, reducing its deficit to $3.7 million, whilst FanDuel earned $19.9 million, cutting its losses to below $905,000.
