## Definition
**Fantasy sports** are contests in which participants assemble virtual rosters of real athletes and score according to those athletes' recorded performances. Season-long and daily formats transform games into portfolio selection, prediction, and comparative ranking.
## Significance
Fantasy sports add a second game above the game. Participants do not control athletes directly; they optimize a model fed by real-world performance data. This makes fantasy play a clear example of simulation, scoring, and financialization layered over tournament infrastructure.
