PredictBay™ Emerges From Stealth With $26.1 Billion in Paper Volume and 1-Minute Sui Prediction Markets, Taking Aim at Polymarket and Kalshi

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.
