Solutions
How Prophecy solves current problems
Problem #1
Fragmented Prediction Market Data
The prediction market landscape is scattered across multiple venues (Polymarket, Kalshi, etc.), each with incompatible data formats, delayed feeds, and price gaps that make it impossible to get a clear, unified picture of market probability.
A single deterministic data stream that consolidates all venues into one standardized, real-time feed — giving clients one source of truth instead of juggling dozens.
Problem #2
Operational Complexity of Multi-Venue Integration
Building on top of prediction markets today requires teams to manually integrate multiple APIs, handle on-chain and off-chain data separately, build internal storage, and maintain all of it — a massive engineering burden.
A plug-and-play single API/SDK that replaces all of that internal infrastructure work with one flexible integration, dramatically reducing time-to-market and ongoing maintenance costs.
Problem #3
No Standardized Market Intelligence Layer
The prediction market landscape is scattered across multiple venues (Polymarket, Kalshi, etc.), each with incompatible data formats, delayed feeds, and price gaps that make it impossible to get a clear, unified picture of market probability.
