Which has better odds — prediction markets or sportsbooks?

On most straight bets, exchanges will be cheaper because of lower fees. But sportsbook promos, boosted odds, and sign-up bonuses can flip that on individual bets. The move is to check both and take the better number.

Yes — and a lot of serious bettors do exactly that. Having accounts on both gives you more options to shop for the best price. When the exchange and the book disagree on a price, that's where arbitrage opportunities come from.

Are exchanges safer than sportsbooks?

Different risks. Sportsbooks are regulated by state gaming commissions. Kalshi and Polymarket US are CFTC-regulated. The international version of Polymarket runs on crypto, which carries smart contract and custody risk. Different platforms, different protections.

Can I live-bet on prediction markets?

Contract prices update in real time, so you can trade during events. But it feels different from sportsbook live betting — you're placing limit orders, not accepting posted odds, and liquidity can get thin during a game.
