Betting AMM vs. Prediction Market: Which Trade-Off Makes More Sense?

Azuro is a decentralized betting protocol that uses pooled capital to support onchain betting applications. Rather than waiting for another bettor to post a matching order, a bettor can accept an available odds quote, subject to the market’s wager limits. The pool’s capital backs potential payouts; it does not make every stake size available at the same price.

A quote reflects the risk the pool is taking. If wagers pile up on one outcome, taking more of that exposure may become less attractive to the pool, so the odds offered on subsequent bets can change. That is the practical reason to understand how betting AMMs price a wager before treating a displayed quote as a standing price for any amount.

Once a wager is accepted, the bettor’s concern is whether that outcome wins under the wager’s terms. Liquidity providers face a different risk: across many wagers, payouts and pricing may leave the pool with a loss. Azuro is a fit for examining that trade-off through applications built around pooled betting, rather than a market in which participants must find counterparties for each order.

Polymarket suits participants who want to set a price for outcome shares rather than take a quoted wager. Buyers post bids, sellers post asks, and a trade occurs when prices match. If the lowest ask is 57¢, a buy limit of 57¢ or more can fill immediately—but only for the shares offered at that price. A larger order may fill partly, then wait for more sellers. A 55¢ limit waits unless an ask falls to 55¢ or lower.

Selling before resolution works in reverse: an immediate sale depends on available bids and their size. The payout of a prediction market share is separate from what another trader will pay for it today.
