How Are Odds Calculated?
Percentages on ShowStakr represent the current distribution of stakes for each option.
Example
In a market predicting "Will Team A win the championship?":
This means 65% of total staked USDC is on Team A. If Team A wins, those stakers share the entire pool proportionally.
The Underdog Advantage
Staking on the less popular option yields higher returns if you're right. Fewer stakers means a larger share of the losing pool for each winner.
How Are Polls Resolved?
Poll resolution determines which option won and triggers payouts to winners.
Resolution Process
Poll outcomes are determined by platform administrators based on verifiable real-world events. We use official sources and wait for confirmed results before resolving.
Automatic Payouts
Once resolved, winnings are automatically calculated and added to winners' balances. You'll receive a notification when this happens.
Cancelled Polls
If a poll is cancelled (e.g., event didn't happen), all stakes are fully refunded to participants automatically.
Winnings & Payouts
When your prediction is correct, here's how payouts work.
How Winnings are Calculated
Winners share the entire pool proportionally based on their stake amount relative to the winning side's total.
Example:
Total Pool: 100 USDC
Your Stake: 10 USDC (on winning side)
Winning Side Total: 60 USDC
Your Share: 16.67 USDC
(10/60 × 100 = 16.67)
Profit Potential
Your profit = Your share of pool - Your original stake. In the example above: 16.67 - 10 = 6.67 USDC profit (66.7% return).

Minimum stake is 0.1 USDC. Maximum limits may vary by poll and are shown when placing your stake.
