Predictbook (also known as Predictbook.co) is a prediction markets intelligence desk. It is platform focused on the prediction market ecosystem. Founded in July 5, 2026 and based in Tel Aviv, Israel, the platform operates as an independent intelligence desk. Predictbook provides real-time market tracking, data analytics, and financial analysis tailored for traders, journalists, and observers.[1][2]
History
Predictbook was established on July 5, 2026.[1] The company focuses on prediction market platforms such as Polymarket and Kalshi, which handle the majority of the industry's trading volume.[3]
Predictbook was founded by Tal Shmuel Harel and Afik Rechler. Tal Shmuel Harel also manages the company's Substack profile.[4][2]
Mission
Predictbook was built with the stated mission of making prediction markets "legible." While raw betting odds show what the crowd believes, Predictbook was designed to explain why the market is pricing events a certain way, whether real-world data justifies it, and where mispricing hides.[3] The company’s broader vision is to treat prediction markets as serious informational infrastructure for forecasting the future, similar to how traditional finance uses the bond market to read interest rates.[3]
Services and features
Predictbook functions as a combined automated data feed and editorial news desk. Its core features include:
- Real-time market tracking: Predictbook parses large-scale, on-chain transactions across prediction markets. It provides 24/7 automated alerts on significant "whale" wallet movements and algorithmic bot execution.[2]
- Arbitrage identification: Predictbook scans for cross-platform price spreads, alerting traders to arbitrage opportunities where the same event is priced significantly differently on competing exchanges (for example, Polymarket vs. Kalshi).[5]
- Market analysis: The editorial desk publishes original articles, daily recaps, and weekly summaries about market movements.
- Social Feeds: Predictbook distributes its real-time signals to subscribers instantly via messaging and social apps such as Telegram and X (formerly Twitter).[5]
Predictbook's statistics that are cited in its analyses have dates and sources. There are also article links that allow readers to verify the information independently.[3]
