The two sportsbook brands’ prediction products are close cousins: both are US-only brokers offering CFTC-regulated contracts, centred on sports. FanDuel Predicts is scored on our model and available in all 50 states for financial contracts; DraftKings Predictions is newer, unscored so far, and excludes Maine and New Hampshire.
Not enough recorded facts on both sides to call a row-by-row edge yet.
Our model uses 9 criteria with fixed weights. We score the evidence we can document and leave unassessed criteria unrated. Funded-account tests are shown only when a review includes a dated test record. Liquidity has the largest declared weight (20%); commercial relationships do not affect scores.
