Bottom line

Which is actually better?

Prediction markets are better for: analytical traders, long-term profitability, avoiding sportsbook limits, and trading early exits.

Sports betting is better for: large positions, instant payouts, and deep liquidity on mainstream events.

For most experienced bettors with an edge, the math favors Polymarket. The lower vig means a skilled trader needs only a 52–54% win rate to profit long-term, versus 55–58% on a traditional sportsbook. Over hundreds of bets, that gap is the difference between profit and the slow grind of a losing season.

The four reasons sharps are migrating.

Odds comparison

Same Lakers game, different math.

On Polymarket, Lakers YES trades at $0.48, implied 48% probability, ~3% effective vig. If Lakers win, your $0.48 share settles at $1.00 for a +108% ROI. Long-term break-even win rate: 52.5%.

On DraftKings, Lakers moneyline is −115, implied 53.5% probability, ~7% effective vig. Bet $115 to win $100, +87% ROI on the same outcome. Long-term break-even win rate: 56%.

On 100 bets with a 55% true win rate, the math says Polymarket nets ~+$1,200 vs ~+$400 on DraftKings: same edge, three times the profit. The vig is the silent tax on every position you take.
