The Flagship Indices
Six indices run live today, spanning the two families where a continuous benchmark is worth the most: macro prints (published slowly, traded constantly) and pre-IPO valuations (no public mark at all between rounds).
| Symbol | Index | Unit | Underlying question | API slug |
|---|---|---|---|---|
MGDP | US Real GDP Growth | % | Crowd-implied US real GDP growth for 2026 | us-gdp |
MCPI | US CPI Inflation (YoY) | % | Year-over-year CPI, implied continuously between prints | us-cpi-yoy |
MUNEMP | US Unemployment (U-3) | % | The U-3 rate, priced off the release markets | us-unemployment |
MOAI | OpenAI Valuation | $ | What OpenAI is worth today, as a continuous mark | openai-ipo-closing-market-cap |
MANTH | Anthropic Valuation | $ | Anthropic’s implied valuation, glided toward its crowd-implied IPO cap | anthropic-ipo-closing-market-cap-979 |
MKRKN | Kraken Valuation | $ | Kraken’s crowd-implied IPO valuation vs. its last primary round | kraken-ipo-closing-market-cap-above |

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)
The catalog is bigger than the board. 57 indices are built across 11 categories (real estate, macro, companies, crypto events, politics, sports, culture, and more). The public board is deliberately curated to the six flagships for launch; tell us what you want to list and we can enable it.
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.
