How to play Big Sumo

The consumer battle in prediction markets is increasingly visible. Kalshi, Polymarket and newer entrants are expanding their sports products, while DraftKings, Flutter, Robinhood and a host of others are investing in exchanges, distribution and market-making capabilities.

The investment banking and capital markets firm Jefferies said in a September report that sports had become prediction markets’ “most important liquidity driver”, with combo and parlay-style contracts accounting for an increasing share of activity.
