Prediction markets are becoming a real-time signal layer for the world.
Every trade updates a probability. Every market reflects a belief about the future.
From viral stories about manipulated weather bets to geopolitical markets repricing in real time, platforms like Polymarket are becoming a live feed of what people believe will happen next.
But until now, accessing that data has been fragmented, noisy, and hard to work with.
Today, we’re launching the Prediction Markets API — a simple way to query markets, prices, activity, and user positions from Polymarket through a single interface.
🧠 Why this matters
Prediction markets aren’t just betting platforms.
They are:
- A real-time aggregation of global expectations
- A continuously updating probability layer
- A new kind of signal for developers, traders, and AI systems
We’re already seeing:
- Markets move meaningfully in response to real-world events
- Liquidity concentrate around key narratives
- Probabilities shift as new information emerges
Example:
“Will Trump acquire Greenland before 2027?”
↓ ~9% → ~7% in ~10 days
(~22% drop in implied probability)
Prediction markets don’t just reflect opinions–they reprice expectations. This is the kind of signal that’s now accessible via API.
🧩 What we built
The Prediction Markets API provides:
- Market data — prices, outcomes, metadata
- OHLCV — historical price action per token
- Activity feeds — trades, splits, merges, redemptions
- Open interest — liquidity across markets
- User data — positions and P&L
- Platform aggregates — macro-level insights
All exposed through:
/v1/polymarket/*
⚡ Key features
- Production-grade — built on on-chain Polygon data
- Enriched — combines blockchain events with Polymarket metadata
- Real-time — continuously updated activity and pricing
- Scalable — from scripts to always-on agents
- AI-ready — structured for LLMs and autonomous systems
🛠️ What you can build
We’re already seeing teams use this to:
1. Track probability shifts
Monitor how markets reprice in response to events
2. Backtest trading strategies
Replay historical OHLCV and activity data
3. Build dashboards
Surface real-time market sentiment
4. Copy trading systems
Follow top wallets and mirror behavior
5. Power AI agents
Give models access to structured “future probabilities”
📊 Example: market repricing
Using the API, you can query:
- historical prices
- volume spikes
- activity patterns
And detect moves like:
- rapid probability drops
- liquidity surges
- asymmetric buying/selling
This turns prediction markets into something more than bets:
a structured signal layer you can build on
🔌 How it works
- Request an API key
- Choose your endpoint
- Query data via REST
- Build your app, model, or strategy
🌍 Why Pinax
The Prediction Markets API is part of the Pinax Token API, which provides:
- multi-chain data access
- consistent REST interfaces
- developer- and AI-friendly design
What makes this different:
We combine raw on-chain data with structured market metadata — so you don’t have to.
🚀 Get started
Prediction markets are evolving from niche platforms into a real-time layer of global expectations.
We’re building the infrastructure to make that data accessible.
🛠️ We’re building this with you
