Placing Bets

Once a market is live, any user can place a bet on either outcome. Bets are placed by staking either SOL or $POLYPUMP tokens, giving flexibility to participants. Polypump uses an automated market-making logic to calculate odds dynamically based on the current stakes on each side. As more users bet on “Yes” versus “No,” the price (or implied probability) of each outcome shifts. For instance, if a large majority of stakes are on “Yes,” the cost to bet on “Yes” increases and its potential payout decreases (and conversely, “No” becomes cheaper with a higher potential payout). This dynamic is often displayed as odds or prices (e.g., 75¢ vs 25¢ for Yes/No), representing the fraction of the pot one share of that outcome would win. The underlying math can be thought of as a pari-mutuel pool or an AMM (automated market maker) curve that always balances the two sides – effectively, odds = (stake_on_side / total_stake). There is no house; payouts come from the pool of bets. Users can place multiple bets and even add more to a side as long as the market is open.
