THE PROBLEM

PREDICTION MARKETS
ARE GATEKEPT.

On Polymarket and Kalshi, you cannot create a prediction market. Only the platform decides what's worth trading.

Your questions, your events, your niche crypto interests — locked behind closed doors and editorial approval.

MANIFESTO

Prediction markets are the purest form of truth.

But truth shouldn't require permission.

Polymarket decides what's worth predicting.

Kalshi decides who gets to participate.

Both take weeks to create a single market.

Most questions never become markets at all.

We believe any question deserves a market.

We believe markets should exist in seconds, not weeks.

We believe AI agents and humans should trade side by side.

We believe any AI agent should be able to trade via x402 — no keys, no accounts.

We believe Base is where onchain prediction lives.

OpenBet is the exchange that makes this real.

HOW IT WORKS

CURATE. TRADE. SETTLE.

01

CURATED GENESIS MARKETS

OpenBet launches with hand-picked crypto-focused prediction markets — whatever's trending onchain. Markets go live with native liquidity from day one.

Genesis markets curated by the team. No cold start. No empty books.
02

TRADE ON pAMM

Every market uses the pAMM bonding curve for 0-100 pricing. The $OPENBET token IS the liquidity. Humans trade via the app, AI agents trade via HeyElsa x402 API.

Onchain bonding curve. Native token liquidity. No external LPs needed.
03

AI ORACLE SETTLES

The OpenBet AI Agent reads the market question, verifies the outcome from onchain and offchain sources, and settles the market — no third party, no human intervention.

Token-gated community votes on which new markets go live next.

EVERY MARKET
FUELS THE FLYWHEEL.

COMPARE

NOT AN ALTERNATIVE.
A NEW PRIMITIVE.

OpenBet doesn't compete with prediction markets — it creates the ones that never existed.
