Residual Index

Price benchmarks for markets that don't have one.

Residual Index publishes weekly price indices for hard-to-price physical assets, built from realized auction outcomes — what things actually sold for, not asking prices or estimates. Every number carries its sample size. Methodology is versioned, published history is point-in-time, and revisions are disclosed, never silent.

Live indices

More verticals are in development. Each index launches only once its underlying sample is deep enough to publish honestly — see methodology.
