Why it's different

An archive nobody can rebuild

Pythia runs tick-level recorders against Polymarket around the clock — order books, trades, and resolutions — plus backfilled hourly histories across thousands of resolved markets. Backtests model real costs and report robustness checks, not just returns. The microstructure archive grows every minute, and it cannot be reconstructed retroactively by anyone who wasn't recording.
