Institutional connectivity for prediction markets

Direct, normalized access for trading and research desks.

Who we work with

Built for institutional desks.

Market makers

  • Calibrate spreads and skew against full tick history.
  • Backtest quoting on the same schema you run live.
  • Signed price level deltas rebuild exact book state at any timestamp.
  • Hedge ratios across venues derived from the reference layer.

Prop trading firms

  • Read full book depth before sizing, so the edge survives the quote.
  • Every execution carries price, size, and taker side for flow analysis.
  • Price divergence across venues arrives with fee and spread context attached.
  • One normalized WebSocket keyed by market covers every venue.

Hedge funds & macro research

  • Continuously updated distributions on CPI, payrolls, and FOMC outcomes.
  • A second opinion from a structurally different participant base.
  • Versioned reference data means an ID you cite today still resolves next quarter.
  • Reproduce results months later from the same Parquet archive, queried natively in DuckDB or Spark.
