    RESEARCHAPR 2027 →

    The endgame: a neutral venue where anyone can post a question, stake the bond, and let the crowd price the answer.

    • ○Planned: Permissionless market creation + creator fee share
    • ○Planned: $PBAY staking · governance over fees and listings
    • ○Planned: Oracle dispute layer for messy real-world outcomes

Dates are targets, not promises — engineering reality wins. Milestones are re-priced every quarter.

02 — WHY PREDICTBAY

The prediction market Sui has been waiting for.

PREDICTION MARKET ON SUI

Native to Sui, not ported to it

PredictBay is a prediction market built on Sui from day one. Sui reaches finality in ~400 ms, which is why PredictBay can run 10-second UP or DOWN rounds — a market format no slower chain can settle honestly.

Sui prediction markets →BUILT ON DEEPBOOK PREDICT

Order-book prices, not AMM curves

Every PredictBay market routes through DeepBook Predict, Sui’s shared central limit order book. Liquidity pools at the protocol layer, spreads come from real quotes, and outcomes settle against the on-chain feed — not by us.

DeepBook Predict →KALSHI ALTERNATIVE

The on-chain counterpart to Kalshi

Kalshi is a regulated US brokerage-style event exchange. PredictBay is the wallet-native alternative: non-custodial, global, open 24/7, with a free practice mode that needs no brokerage account and no KYC.

Kalshi alternative on Sui →POLYMARKET ALTERNATIVE ON SUI

Event markets, ten seconds at a time

If you trade Polymarket, PredictBay will feel familiar — then faster. The same YES or NO event markets, priced by an order book instead of an AMM, plus sub-minute crypto rounds that only Sui’s finality makes possible.

03 — FAQ

Asked constantly. Answered once.

Is PredictBay live?
Practice mode is live today at predictbay.io — no wallet, no KYC. The public testnet on DeepBook Predict opens AUG 15 · 12:00 UTC; mainnet and the $PBAY token follow on October 8, 2026 at 12:00 UTC.
What chain is PredictBay on?
Sui — with DeepBook Predict as the order book and Pyth as the oracle. Multichain deposits from ETH, SOL and EVM chains land in Q1 2027; settlement stays on Sui.
How is it different from Kalshi or Polymarket?
Kalshi is a regulated US exchange; Polymarket runs AMM-style markets on Polygon. PredictBay is non-custodial, order-book priced on DeepBook, and fast enough for 10-second rounds — the crypto-native alternative on Sui.
When is the $PBAY token?
Target OCT 8 · 12:00 UTC — community-first, no VCs. Details go out through official channels only. No contract exists yet; anything claiming otherwise is a scam.

Will PredictBay ship mainnet
before October 1?

You can settle this one yourself on October 1. Until then the demo is free, the testnet opens in August, and every date above is a target we re-price each quarter.
