$CORECPI

No listing kit for $CORECPI yet. A kit sets its strikes from 14 published numbers. This index publishes one a month and has none yet.

Index

$CORECPI US 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 is timestamped with the next daily proof, at 12:40 UTC. A month loaded as history is not.

As first published

Aug 2026 was not read when it was first published. It is the Bureau's current figure, loaded later, and it settles nothing.

The number as first published is final for settlement. A revision by the source is shown beside it and never replaces 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 number as first published.

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 number Tickerz first recorded for $CORECPI for the month named in the contract, published at tickerz.com/x/corecpi and in GET /api/indices/corecpi, timestamped daily in Bitcoin with OpenTimestamps.

None on file yet. The Bureau publishes Sep 2026 on Oct 14 2026, 12:30 UTC.

21 months in the chart were loaded later: the Bureau's current figures, not the numbers as first published. The settlement file marks each one and gives it no settlement value.
