Resolution
Index
$CORECPIUS core CPI, month over month. Rulebook v0.2, 2026-10-04.
Prints
Monthly. The Bureau publishes at 8:30 ET, with the Consumer Price Index. Read at 12:35, 13:35 and 14:35 UTC on weekdays. A month read at its release goes on-chain with the next daily proof, at 12:40 UTC. A month loaded as history does not.
First print
No complete month on file yet.
The first print is final for settlement; revisions are shown beside it and never replace it.
Fallback
A month that has not been published stays open. A month the Bureau never publishes is void. A revision is shown beside the first print.
Precision
Percent, one decimal, half away from zero, computed from the index the Bureau publishes to three decimals. The Bureau's public API carries the index and not the percent change, so a venue should check the figure against the Bureau's release.
Cost to move
Not practical. Moving the month means changing the prices the Bureau collects.
Grade
reference. The Bureau of Labor Statistics publishes the index, and a venue can read it. Tickerz keeps the first percent change of each month it reads at release. The Bureau sets the seasonal factors again each February and revises the last five years of the seasonally adjusted index.
For a rulebook
Settle on the Tickerz first print of $CORECPI for the month named in the contract, published at tickerz.com/x/corecpi and in GET /api/indices/corecpi, put on-chain daily with OpenTimestamps.
First prints
None on file yet. A first print is a number Tickerz reads at its release and puts on-chain before the Bureau revises it. The Bureau publishes Sep 2026 on Oct 14 2026, 12:30 UTC.
No forecasts on this index. Calls stay off until a month has been captured as a first print. History loaded at launch is the Bureau's current figure, not a first print.
