What is FRED Economic Data?
FRED, maintained by the Federal Reserve Bank of St. Louis, is an economic-data research service. Its search and release navigation help users find a series, identify its source and place a new economic release in historical context.
For prediction markets, the essential step is matching the contract to the exact measure. A seasonally adjusted index, an unadjusted value and a percentage change can answer different questions even when they share a familiar label.
