PredictBay emerges from stealth with one-minute Sui prediction markets and $26.1bn in paper volume

Published Aug 19, 2026

PredictBay launched from stealth with $26.1 billion in paper volume and one-minute prediction markets on the Sui blockchain. The platform enters a competitive field, positioning itself against Polymarket and Kalshi. Polymarket currently offers five-minute Bitcoin Up or Down markets. Kalshi offers 15-minute contracts. PredictBay's simulated trading volume preceded its public launch. The one-minute market structure targets traders seeking faster resolution than existing regulated venues.

Why this matters?

PredictBay's one-minute markets sharpen the speed war among CFTC-regulated venues. Polymarket's five-minute and Kalshi's 15-minute contracts now look slow by comparison, forcing both to respond or cede high-frequency retail traders. The $26.1 billion in paper volume is simulated, so the platform must convert test users to real capital before incumbents match its interval.

Sui blockchain settlement matters only if traders value on-chain transparency over the familiar rails of Polymarket and Kalshi. Speed alone rarely sustains market share once competitors replicate the interval. PredictBay's survival depends on whether its liquidity matches its clock.
