They look similar — both let you put money on outcomes — but the mechanics and framing differ. Educational only; both involve real risk of loss.
Who sets the price
In a sportsbook, the house sets the odds and builds in a margin (the "vig"). In a prediction market, other traders set the price through buying and selling — you're trading against other participants, not the house.
How you profit
At a sportsbook you win a fixed payout if your bet lands. In a prediction market you can also profit by trading — buying when you think the price is too low and selling higher as the probability shifts, even before the event ends.
Framing: probability vs. wager
Prediction markets are framed around information and probability estimates; sportsbooks around wagering. The overlap is real, which is why treating either responsibly matters.
The risk is real in both
You can lose your entire stake either way. Neither is a reliable income source, and both can become harmful if used compulsively. Use only money you can afford to lose and read managing risk.
