Sportsbooks vs. Prediction MarketsWhich offers the highest payouts on your winning picks?

DraftKings, FanDuel and BetMGM: estimated return equals stake × decimal odds, assuming acceptance of the stake and ordinary winning moneyline settlement. Their margin is built into the odds, not deducted again. The feed does not confirm account-specific stake limits.

ProphetX straight trades: estimate deducts 2% of net gains for this single position, with no other positions in the same market and no rebates. Available stake size, contract increments and final rounding are not verified by this feed. ProphetX trading fees (checked 7 October 2026).

Odds source. Operator update times are shown in each row. Cached prices expire after two hours; started games are excluded.

Prediction-market estimates use an implied share price of 1 ÷ displayed decimal odds. Those odds are rounded; the implied price is not a verified executable quote. We model whole shares, hold to settlement, and fit both purchase cost and estimated entry fee within your budget. Full fills and available liquidity are unverified, including for $100 and $1,000. Confirm before trading.

Polymarket rows use the international platform feed, not Polymarket US. Access and eligibility vary by location. Polymarket estimates assume the international platform’s taker formula: shares × fee coefficient × price × (1 − price), rounded to five decimals. We assume 0.05 for sports, or 0.03 for NFL purchases during October 2026 under the published promotion. These coefficients are not flat percentages of your budget. Exact market fees, older schedules, rebates and execution rounding may differ. Estimates assume 1 USDC = $1, with no conversion or payment costs. Polymarket fee schedules · Formula.

Kalshi fallback estimates assume the general taker multiplier of 1; they use the same formula and rounding below with an implied price and unverified fill size. A matching fresh order book takes priority and is labelled “Verified quote”. That label describes the captured price and quantity, not a guaranteed execution.

For verified quotes, Kalshi uses the best available YES purchase price, derived from the highest NO bid. The calculation buys whole contracts only, limited to the quantity available at that price. It does not assume the rest of your stake can fill at the same price or sweep deeper price levels.

Estimated immediate-execution fee: multiplier × 0.07 × contracts × price × (1 − price). For verified quotes the multiplier is retrieved from the market series; fallback estimates assume 1. Trade cost plus fee is rounded up to $0.0001 under the published July 7, 2026 schedule. Displayed dollar figures use two decimals; totals use the underlying precision. Multiple executions and later fee changes may affect the final charge. There is no Kalshi settlement fee under this schedule.

MLS uses the 90-minute home/draw/away (1X2) market, including stoppage time but excluding extra time and penalties. A draw wins only when you select Draw. Operators without a complete three-outcome price set are excluded, so two-way or draw-no-bet prices are not mixed into the comparison.

Selected market’s settlement rules

Select an available market to read its rules.

Results shown assume your selected outcome wins and settles at $1 per contract. Ties, cancellations and postponements may settle differently; they are not necessarily equivalent to a sportsbook void or push. No cross-platform winner will be declared without matching settlement terms.
