About Outcalled

What is Outcalled?

Outcalled is a free prediction game platform where you test your forecasting skills against real market data. Every game uses live data from Polymarket, the world's largest prediction market. No sign-up required, no money needed. Just your instincts versus the crowd.

Think of it as Wordle meets prediction markets. Each day, you get 5 resolved markets and guess whether they happened or not. Share your score, build your streak, and compete with friends.

Our Mission

Prediction markets are one of the most powerful tools for understanding the future. But most people have never used one. Outcalled exists to change that by turning prediction markets into something anyone can enjoy, no crypto wallet or trading experience required.

We believe that making predictions accessible through fun, viral games is the best way to introduce millions of people to this space.

How It Works

Every game on Outcalled is powered by real data from Polymarket. We pull live market prices, probabilities, and resolved outcomes through their public API. When you play a game, you are engaging with real markets that have real money behind them, giving you access to the wisdom of thousands of traders.

7 Game Modes

Outcalled offers seven different ways to test your prediction skills:

• Daily Game - 5 resolved markets, yes or no, once per day. The core Outcalled experience. Build streaks, share your score, come back tomorrow.
• Battle Mode - Head-to-head prediction battles. Swipe Tinder-style on 5 markets and compare scores against an opponent.
• Speed Round - 20 markets in 60 seconds. Pure speed and instinct. How fast can you read and react?
• Margin Call - Guess the exact probability of each market. The closer you get, the higher you score. Precision matters.
• Prediction Parlay - Double or nothing. Chain correct predictions together, but one wrong call and you lose everything.
• Category Blitz - Pick your niche (politics, crypto, sports) and face 10 markets in 45 seconds.
• Streak Challenge - Infinite mode. How many correct predictions can you chain together before you miss?

Powered by Polymarket

All game data comes from Polymarket, the world's largest prediction market platform. Polymarket lets real traders bet real money on thousands of real-world outcomes, from elections to crypto prices to pop culture. This means the probabilities you see in our games reflect actual market sentiment backed by millions of dollars in volume.

We use Polymarket's public API to fetch market data, prices, and resolution outcomes. Outcalled is not affiliated with Polymarket. We are an independent project that builds games on top of their data.

How Outcalled Makes Money

Transparency matters to us. Outcalled earns revenue through Polymarket's affiliate program. When you click a link to Polymarket from our site and sign up to trade, we earn a referral commission. That is it. No ads, no premium subscriptions, no selling your data.

Every "Trade on Polymarket" button includes our referral link. We believe this is fair: we introduce you to prediction markets for free, and if you decide to trade, we get a small commission from the platform.
