There are dozens of prediction products. Here is what makes Prediction Arena different — and why we believe these differences matter.
1. Truly non-custodial
Your stake never touches our wallet, our database, or our balance sheet. It moves from your wallet directly into an audited smart contract, and from that contract directly back to your wallet when the round settles. We could not seize, freeze, or rehypothecate user funds even if we wanted to — the contracts are non-upgradeable on the dimensions that matter.
We do not store private keys. We do not store seed phrases. We never ask for either. Anyone who does is not us.
2. Oracle-verified settlement
Settlement prices are not chosen by Prediction Arena. They are produced and cryptographically signed by Pyth Network publishers — a consortium of exchanges and trading firms whose business is producing real-time prices. Our settlement contract refuses to accept any price that is not signed by the Pyth guardian set, and refuses to settle if the price’s confidence interval exceeds a per-market safety threshold. In practice this means:
- We cannot fake a price to favor either side.
- A compromised admin key cannot fake a price either — the worst it can do is delay settlement until a real signed price arrives.
- Wide-spread, low-liquidity moments (e.g. metals over a holiday weekend) are automatically rejected rather than settled on garbage data.
3. Anti-copytrade protections
Most prediction sites leak information. Order books, public mempools, “live” leaderboards — all of it lets sophisticated actors mirror retail traders in real time and skim the alpha. Prediction Arena is built around a commit-reveal flow: predictions are committed as opaque hashes during the active window, and only revealed after the window closes. Nobody — not other players, not bots watching the mempool, not us — can see your pick until it is locked in and unchangeable.
4. Sybil-resistant tournaments
Bracket-style tournaments on most platforms are won by whoever spins up the most wallets. Prediction Arena’s tournament contract requires every entrant to commit their entire bracket upfront, anchored by a single on-chain commitment. Late-stage strategy switching, bracket-swapping, and “multi-account hedging” are mathematically impossible. ESPN-style path-dependent scoring further punishes lucky guesses and rewards genuine forecasting skill.
5. Transparent rake, no hidden fees
A flat, published rake is taken from each pot. There are no spread games, no priority-fee auctions, no “premium” tiers, no VIP rebates. What you see is what every player sees.
6. Verifiable, every step
Every round leaves a permanent on-chain trail: the strike price, the settlement price, the signed oracle attestation, the payout transactions. Anyone — including you, including a journalist, including a regulator — can independently verify any round we have ever run. We will publish a one-click “verify this round” button next to every settled round in the UI.
7. Built by people who actually use it
We are traders. We have been on the wrong side of opaque settlement, custodial bankruptcies, and toxic order flow. Prediction Arena is the product we wanted to exist.
