Daily fantasy sports (DFS), a rapidly growing industry, allows players to create fantasy teams of real-life players and potentially win cash prizes, derived from entry fees. Some stakeholders have expressed concern that DFS's accelerated nature and other features might promote excessive play and related harm. We conducted the first descriptive summary of actual DFS play using records from a cohort of subscribers to a dominant operator, DraftKings. Participants (N = 10,385) initially entered paid National Football League (NFL) contests. Across all participants, players entered a median of two contests per entry day and typically submitted a single entry for each contest they entered. Players paid a median of $87 in entry fees throughout the 2014 NFL season and experienced an overall median net loss of $30.7. However, we identified heavily involved sub-groups of players based on number of contests entered, total entry fees, and net loss. These top 1% groups were less likely to restrict themselves to NFL games, exhibited greater time involvement, but also won a greater percentage of the contests they entered than typical players. Our observations of typical and heavily involved players tend to mirror those generated in previous Internet sports gambling research.
每日梦幻体育（DFS）是一个快速发展的行业，允许玩家创建由现实生活中的球员组成的梦幻球队，并有可能从参赛费中赢得现金奖励。一些利益相关者表示担心，DFS 的加速发展和其他特点可能会促进过度参与和相关的伤害。我们使用一家主导运营商 DraftKings 的订阅者的记录，对实际 DFS 游戏进行了首次描述性总结。参与者（N=10385）最初参加了付费的国家橄榄球联盟（NFL）比赛。在所有参与者中，玩家平均每个参赛日参加两个比赛，通常每个参赛比赛提交一个参赛。在 2014 年 NFL 赛季中，玩家支付的参赛费中位数为 87 美元，总损失中位数为 30.7 美元。然而，我们根据参赛次数、参赛总费用和净损失确定了一些重度参与的玩家子群体。这些前 1%的群体不太可能仅限于 NFL 比赛，表现出更多的时间投入，但他们赢得的参赛比赛比例也高于普通玩家。我们对典型和重度参与玩家的观察结果往往与之前互联网体育博彩研究产生的结果相似。
