The Flagship Indices - Mecone

Eight indices run live today, spanning three families where a continuous benchmark is worth the most: macro prints (published slowly, traded constantly), pre-IPO valuations (no public mark at all between rounds), and GPU rentals (a real market with no reference price).

Resolution sources

Every anchored index settles to the exact official series its underlying market resolves on, the discipline of a benchmark administrator:

CPI: BLS CPI-U (NSA, YoY)
GDP: BEA advance estimate (first release)
Unemployment: BLS U-3
Valuations: the event’s own resolution (e.g. IPO pricing)

Data sources

Indices are computed from public prediction-market data (Polymarket order books over WebSocket; Kalshi public REST), official statistics (FRED/ALFRED first-release vintages), and, for real estate, Parcl Labs price feeds. Each index’s page on the terminal shows its sources and current book depth.
