The Silicon Valley-built, Panama-incorporated PredictBay.io is preparing one-minute UP/DOWN markets on Sui's DeepBook Predict, combining sub-second blockchain settlement, shared liquidity, zkLogin and an options roadmap spanning crypto, gold, oil and eventually 24/7 equities
SAN FRANCISCO, Aug. 19, 2026 (GLOBE NEWSWIRE) -- PredictBay™, a new consumer prediction-market platform built on Sui's DeepBook Predict, is coming out of stealth with numbers designed to get the prediction-market industry's attention: more than $26.1 billion in simulated paper-trading volume and more than $1.30 billion in simulated paper-trading fees since its stealth launch in January 2026 , according to the company's current trading dashboard.
Those figures are simulated rather than real-money revenue - but that is exactly the point. PredictBay™ says the activity was generated during months of product testing, without a paid marketing campaign, as the team fine-tuned a trading experience intended to make high-speed prediction and options markets feel less like a crypto terminal and more like a consumer app.
Now the stealth period is ending.
PredictBay™ says its next phase will introduce 1-minute UP/DOWN prediction markets , broaden public access to its Sui testnet experience, distribute more than 1 million dUSDC testnet units for users to put the system through its paces, and prepare for a DeepBook Predict mainnet rollout later in 2026. DUSDC is DeepBook Predict's Testnet quote asset; testnet balances are not cash and are being used to test the system with the early community.
And the one-minute market may be the feature that immediately puts PredictBay™ into the Polymarket-versus-Kalshi conversation.
As of August 17, Polymarket is offering 5-minute Bitcoin Up or Down markets, while Kalshi is offering 15-minute BTC Up or Down markets. PredictBay's announced one-minute format would make its round duration five times shorter than Polymarket's current five-minute BTC format and fifteen times shorter than Kalshi's current 15-minute product. That comparison concerns market duration rather than a blanket claim about matching-engine latency, but for retail users it creates a radically different loop: choose UP or DOWN, watch the market resolve, and move to the next opportunity within a minute.
A Polymarket Alternative Built More Like an Options Engine
What could make PredictBay™ more consequential than simply another prediction-market frontend is the infrastructure underneath it.
DeepBook Predict is the third financial primitive in the DeepBook stack, alongside Spot and Margin. Sui describes Predict as an on-chain prediction and options primitive capable of supporting binary markets, options, leveraged products and structured instruments. Its options pricing infrastructure was developed with Block Scholes, and Sui says transactions can settle in under 400 milliseconds.
DeepBook Predict also approaches liquidity differently from a conventional prediction-market order book. Its current documentation describes liquidity providers supplying quote assets into a shared vault , against which applications can mint and redeem oracle-priced binary positions and vertical ranges.
That matters because liquidity fragmentation is one of prediction markets' hardest scaling problems.
Polymarket documents a CLOB architecture in which user orders are created off-chain, matched by an operator and then settled on-chain, with markets relying on their order books for price discovery. Kalshi likewise exposes order books for individual market tickers, while Kalshi Alternative PredictBay does not. DeepBook Predict instead is designed around an on-chain options primitive with shared liquidity and composability across the broader DeepBook stack. Sui describes the architecture as enabling Predict positions to compose with Margin, Spot and other Predict positions rather than ending as isolated binary tokens.
DeepBook's own technical presentation goes further: it describes shared liquidity as a way to reduce fragmentation across large numbers of markets and calculate option contract pricing on demand.
That distinction could become increasingly important as PredictBay™ moves beyond simple UP/DOWN markets.

Prediction Markets Are the Front Door. Options Are the Bigger Bet.
PredictBay's vision is much larger than guessing whether Bitcoin moves up or down over the next minute.
DeepBook Predict's architecture treats many of these products as options under the hood. Its roadmap extends from binary markets into ranges, calls, puts, spreads, leveraged exposures and structured products. DeepBook's own presentation describes an eventual expansion from Bitcoin into crypto, equities and real-world assets, including the concept of trading an S&P 500 UP/DOWN market around the clock.
For PredictBay™, that points toward an eventual consumer market covering Bitcoin, Ethereum and other digital assets, gold, silver and potentially broad equity markets - 24 hours a day, seven days a week where legally available.
The ambition is to hide most of that complexity.
A user should not need to understand options Greeks, manage a seed phrase or learn an institutional trading terminal to express a simple market view. Sui's zkLogin technology can turn an existing OAuth login such as Google or Apple into a Sui address without exposing users to seed phrases or persistent private-key management.
For PredictBay™, the intended experience is deliberately simple: log in, select a market, choose UP or DOWN, select a stake and trade.
