PredictBay has exited stealth with a striking simulated trading record: more than $26.1 billion in paper volume and over $1.30 billion in simulated fees accumulated since January 2026. The consumer platform, built on Sui’s DeepBook Predict, generated those figures organically during product testing without any paid marketing. Now the team is preparing one-minute UP/DOWN market data, expanding Sui testnet access, and planning to distribute more than 1 million dUSDC testnet units for broader stress testing.
The shorter market duration immediately distinguishes the offering. While existing prediction market platforms run five-minute or fifteen-minute Bitcoin direction contracts, PredictBay’s sixty-second cycles create a much tighter feedback loop for traders. Sub-second settlement on DeepBook Predict underpins the experience, allowing rapid resolution that feels closer to a mobile game than a conventional trading screen. Much closer.
Paper Volume Built Quietly Before the Public Debut
The $26.16 billion in cumulative paper volume stands out because it grew even as the product remained largely out of view. PredictBay’s dashboard tracked steady activity as the team refined market mechanics and a simplified interface aimed at everyday traders. The parent startup has raised more than $8.2 million yet kept its corporate identity low-profile so attention stays strictly on the product itself.
Paper trading is the only live mode today; balances carry no cash value, and the DeepBook Predict integration remains on testnet. Contracts may still change before mainnet. Even so, the scale of simulated activity supplies concrete evidence of demand ahead of any public marketing push.
Zack Nelson has joined as Chief Marketing Officer to lead the next phase. Nelson, founder of Genzio Media, brings experience supporting major crypto projects and is already preparing a Sui Basecamp session on making advanced tools feel accessible.
One-Minute Markets and the Underlying Technology
The core new feature is the one-minute UP/DOWN format. Traders pick a direction on an asset price and see the outcome settle inside sixty seconds—five times faster than current five-minute Bitcoin markets and fifteen times faster than fifteen-minute versions. DeepBook Predict handles settlement through an on-chain options primitive that supports binary positions and shared liquidity via a vault model, reducing the fragmentation common in isolated order books.
Transactions confirm in under 400 milliseconds with negligible gas costs, thanks to Sui’s parallel execution. zkLogin lets traders sign in with Google or Apple accounts, removing seed-phrase friction. Oracle feeds from Pyth determine final prices, keeping outcomes transparent and on-chain.
Beyond binary markets, the product roadmap includes ranges, calls, puts, spreads, and leveraged structures. Longer-term plans cover additional digital assets, gold, oil, and equity indexes on an ongoing basis, where available. A fair-launch utility token, $PBAY, is also in the works, though no contract exists yet and final terms remain subject to disclosure.
What Traders Can Expect Next
Public testnet access is expanding now, with mainnet targeted for later in 2026. The distribution of more than 1 million dUSDC testnet units will give a broader group of traders hands-on experience before live trading begins. Access remains jurisdiction-dependent and is currently restricted in the United States and several other regions.
With tens of billions in simulated volume already recorded, PredictBay enters this competitive field carrying proven engagement data. The combination of ultra-short markets, sub-second rails, and frictionless onboarding forms the central pitch as the platform moves from testing into wider public visibility.
