Markets Index
Where the money questions trade. Bitcoin, the S&P 500 and US growth expectations are each read off real-money prediction markets — strike ladders, range bins and growth contracts — on one shared 0–100 scale: 50 = a balanced book, above 50 = bulls or optimism paying up, below 50 = bears or recession fear in control.
US GDP Index
A market-implied read of economic-expectation sentiment — not a GDP forecast. Prediction-market GDP-growth contracts are folded by period into an expected growth rate, then mapped to a 0–100 scale where 50 = the market expects growth at potential (~2%), above 50 = optimism / expansion, below 50 = recession fear.
By Period
Each period folds every venue's GDP-growth contracts for that year or quarter into one market-implied expectation. The score is the sentiment (50 = neutral); the market-implied growth rate is shown alongside.
