Data infrastructure for event contracts

Reconstructable market data. Portfolio-level event analysis.

Expreci provides institutional-grade Polymarket order book data and non-advisory portfolio & scenario analytics for event contracts.

We treat prediction-market positions as a portfolio of binary contingent claims.

Expreci does not provide investment advice, trading recommendations, or portfolio management. Every decision remains with the user.

Designed for

Teams already close to the market

  • Quantitative trading desks evaluating prediction-market microstructure
  • Crypto funds and family offices managing event-contract exposure
  • Market makers and liquidity providers that require sequence-aware books
  • Sophisticated traders managing portfolios across related contracts

Differentiation

Infrastructure rather than a balance display

Most existing tools are either wallet P&L trackers or simple market data dumps. Expreci is designed as infrastructure for teams that need reconstructable books and portfolio-level analysis of binary event contracts.

Product boundary

Decision support, not decision making

Status

Beta Testing

Expreci is currently in Beta stage and is validating requirements from additional prospective users.
