How It Works
Everything you need to know.
How markets are priced, how anyone can create them, and how you collect your winnings.
01 / Market Pricing
Automatic pricing via AMM
Arculate uses a constant-product AMM. The contract sets prices based on how much liquidity flows to each side. No orderbook. No market makers needed.
When more money flows to YES, the YES price rises automatically. The price at any moment is the market's implied probability.
Live probability example
Market opens
$10,000 flows to YES
$25,000 flows to YES
Price equals probability. Always transparent.
Will BTC be above $67,000 in 5 minutes?
Will Argentina win the 2026 World Cup?

02 / Open Markets
Anyone can create a market.
Arculate is open. Any wallet can create a prediction market on any topic and it goes live on-chain immediately. Community markets sit alongside Official markets from the Arculate team.
Live micro-markets are short-duration crypto price markets that open and settle in minutes, powered by Arc's sub-second finality. A new kind of market that isn't practical on any other chain.
03 / Resolution
Transparent, verifiable resolution.
Every market specifies its resolution source before it opens. Official and community markets are resolved by the Arculate team based on publicly verifiable data. Live micro-markets are resolved automatically by the Arculate resolver bot.
Every resolution is a transaction on-chain, verifiable by anyone at any time on ArcScan.
