Title: How to Play Fantasy Sports Strategically (and Win)


Daily Fantasy Sports (DFS) is a multi-billion dollar industry with millions of annual users and widespread appeal among sports fans across a broad range of popular sports. Building on the recent work of Hunter, Vielma and Zaman (2016), we provide a coherent framework for constructing DFS portfolios where we explicitly model the behavior of other DFS players. We formulate an optimization problem that accurately describes the DFS problem for a risk-neutral decision-maker in both double-up and top-heavy payoff settings. Our formulation maximizes the expected reward subject to feasibility constraints and we relate this formulation to the literature on mean-variance optimization and the out-performance of stochastic benchmarks. Using this connection, we show how the problem can be reduced to the problem of solving a series of binary quadratic programs. One of the contributions of our work is the introduction of a Dirichlet-multinomial data generating process for modeling opponents’ team selections and we estimate the parameters of this model via Dirichlet regressions. A further benefit to modeling opponents’ team selections is that it enables us to estimate the value in a DFS setting of (i) insider trading and (ii) collusion whereby a number of DFS players combine to construct a single portfolio of entries to a given contest. We demonstrate the value of our framework by applying it to both double-up and top-heavy DFS contests in the 2017 NFL season. (Joint work with Raghav Singal)
