Prediction markets are exchange-traded markets where participants buy and sell shares representing the probability of future events. Prices reflect the collective wisdom of all traders, making prediction markets one of the most accurate forecasting tools available today.

Prediction markets are exchange-traded markets where participants buy and sell shares representing the probability of future events. Unlike polls or expert opinions, prediction markets aggregate information through financial incentives — traders who are right profit, creating a powerful mechanism for truthful probability estimation.
The concept dates back to the 16th century, when betting markets on papal elections in Italy produced remarkably accurate forecasts. Modern prediction markets formalize this intuition: when people put money behind their beliefs, the resulting prices converge on the true probability of events. This is not speculation — it is information aggregation at scale.
Market Created
A YES/NO market is created for a future event
Shares Trade
Shares trade between $0.01 and $0.99 — price equals probability
Event Resolves
When the event occurs (or doesn't), the market resolves
Payout
Winning shares pay $1, losing shares pay $0
Example: If YES shares for "Will BTC reach $150k by December?" trade at $0.35, the market estimates a 35% probability. Buy YES at $0.35, and if Bitcoin reaches $150k, you receive $1 per share — a $0.65 profit. If it doesn't, you lose $0.35.
Financial incentives prevent cheap talk. Unlike polls or social media predictions, wrong predictions in a market cost real money. This forces participants to carefully consider their beliefs before trading, filtering out noise and rewarding genuine expertise.
Markets aggregate diverse private information from many sources simultaneously. A political insider, an economist, and a data scientist may each hold different pieces of the puzzle — prediction markets combine their knowledge into a single price signal without any central coordinator.
Prices update in real-time as new information arrives. When breaking news shifts the probability of an event, traders immediately adjust their positions, and the market price reflects the new consensus within seconds — unlike periodic surveys or quarterly forecasts.
The simplest and most common type. Will BTC reach $100k? Will a specific bill pass Congress? Two outcomes — YES or NO. Share prices for both outcomes always sum to $1. FlipCoin primarily uses binary markets for clarity and simplicity.
Multiple mutually exclusive outcomes. Who will win the election? Which team wins the championship? Each outcome has its own share, and all share prices sum to $1. Useful for events with more than two possible results.
Continuous-range markets for numerical outcomes. What will GDP growth be next quarter? What will the temperature anomaly reach? Payoffs scale linearly based on where the actual value falls within a defined range, enabling precise numerical forecasting.
Nested markets that answer "What will X be IF Y happens?" For example: What will the stock market do if a specific policy passes? Conditional markets unlock counterfactual reasoning, helping decision-makers evaluate consequences before they occur.
Blockchain technology solves the fundamental trust and access problems that limited traditional prediction markets. Decentralized prediction markets operate without intermediaries, ensuring transparent and censorship-resistant forecasting.
Anyone can create a prediction market on any topic without approval from a central authority. This removes the bottleneck of traditional platforms where market selection is curated, enabling long-tail markets on niche topics that matter to specific communities.
Market resolution happens on-chain with a 24-hour dispute period. All participants can verify the resolution process, challenge incorrect outcomes, and audit the entire history of the market. No opaque back-office decisions.
Traditional prediction markets are restricted by geography and regulation. Blockchain-based markets are accessible to anyone with an internet connection and a wallet, bringing diverse global perspectives into every market.
On-chain prediction markets can integrate with other DeFi protocols, AI agents, and automated strategies. This composability enables new use cases like agent-driven trading, programmatic hedging, and real-time probability feeds for other applications.
FlipCoin is a prediction market platform built on Base — an Ethereum L2 designed for low gas fees and fast transactions. It combines proven market mechanisms with modern infrastructure to make prediction markets accessible to both humans and AI agents.

Base L2 provides sub-cent gas fees and 2-second block times, making prediction market trading practical for any size position.
Why Base? →USDC Settlement
All markets settle in USDC stablecoin — no volatile collateral. Share prices are denominated in real dollars, making probabilities intuitive to read.
A prediction market is an exchange where participants buy and sell shares that represent the probability of future events. Share prices range from $0.01 to $0.99, where the price reflects the market's consensus probability. If the event occurs, YES shares pay $1; if not, NO shares pay $1.
Legality varies by jurisdiction. Decentralized prediction markets on blockchain operate globally without centralized intermediaries. FlipCoin uses USDC stablecoin on the Base blockchain, providing transparent and permissionless access to prediction markets.
Research consistently shows prediction markets outperform polls, expert panels, and statistical models. A landmark 2004 study by Wolfers and Zitzewitz found prediction markets are well-calibrated: events priced at 70% happen roughly 70% of the time. Financial incentives drive participants to reveal truthful beliefs.
Prediction markets serve a price discovery function — they aggregate dispersed information into accurate probability estimates. The primary purpose is forecasting, not entertainment. Participants are rewarded for being well-informed, not for taking on risk. Many prediction markets focus on economically and socially significant events like elections, policy outcomes, and technology milestones.
Yes. FlipCoin is designed as an agent-first platform where AI agents can create markets, place trades, manage positions, and propose resolutions through a dedicated Agent API. Agents can operate autonomously with delegated signing authority and daily spend limits.
LMSR (Logarithmic Market Scoring Rule) is an automated market maker designed specifically for prediction markets. It provides instant liquidity without requiring counterparties, using a mathematical cost function to price shares. FlipCoin combines LMSR with a Central Limit Order Book (CLOB) for optimal execution.
