Everything you need to know about trading on PolyFly — from your first bet to lottery predictions.
🪰 What is PolyFly?
PolyFly is a prediction market platform built on Hedera Hashgraph. You bet on whether something will happen — a crypto price target, a sports result, a lottery number being drawn — and if you're right, you win.
What Can You Bet On?
Classic YES/NO markets on real-world events. "Will HBAR reach $0.50 by June?" — anyone can create one, anyone can bet.
Bet on which numbers will be drawn in real EuroMillions and Powerball draws. Every number is its own market.

- → Check the odds — if YES is $0.95, you risk $0.95 to win $0.05
- → Diversify — spread bets across multiple markets or numbers
- → Watch the volume — higher volume = more liquid = better fills
📊 How Betting Works
Prediction Markets (AMM)
Regular prediction markets use an Automated Market Maker. No order books, no counterparty needed — you bet against a pool. Every market has a YES pool and a NO pool. The ratio determines prices.
Example: YES pool has $600, NO pool has $400. YES price = 400/1000 = $0.40. If you buy YES at $0.40 and YES wins, each share pays $1.00 → profit of $0.60 per share.
Lottery Markets (Pool-Based)
Lottery markets work differently: winners split the losers' pool proportionally. No AMM pricing — the payout depends on how many people bet on each side.
| Prediction Markets | Lottery Markets | |
|---|---|---|
| Bet on | Real-world events (YES/NO) | Specific lottery numbers |
| Pricing | AMM (price moves with bets) | Pool-based (winners split losers) |
| Resolution | Admin/oracle resolves | Automatic from official results |
| Payouts | Claim manually | Automatic to your wallet |
| Min bet | $1 USDC | $0.50 USDC |

🎰 Lottery Predictions
PolyFly turns every single lottery number into its own mini prediction market. For each number in an upcoming draw, you bet YES (it will be drawn) or NO (it won't). After the real draw, winners split the losing pool.

The Number Grid
The lottery page shows a colour-coded grid of every possible number. Colours reflect crowd sentiment. Glow intensity shows how much action each number has.

- "Will it rain in London on March 30?"
- "Will Hedera announce a Fortune 500 partnership in Q2?"
- "Will crypto go up?" (too vague)
- "Is HBAR good?" (subjective)
