A New Kind of Market

Opinion, not prediction

Prediction markets ask “what will happen?” - b⁴ asks “what do most people believe?” Markets resolve based on crowd consensus, not real-world outcomes. Your edge isn't knowing the future, it's knowing the crowd.

OLD WAY

Prediction Markets

Bet on whether something actually happens. Requires oracles, real-world event verification, and waiting for outcomes. Resolution is binary and objective.

—Resolves on real-world events
—Needs trusted oracles
—Wait days, weeks, or months
b⁴ WAY

✓No oracles, the crowd decides
✓24-hour resolution cycles
Simple. Fast. Fun.
