One-time source collection

Inspect the evidence behind the contract

Collect exact source passages and export them with this contract’s identity. No sign-in required.

Recognized complete terms receive a rule-based reading, including supported Fed, GDP, Core PCE/Core CPI monthly and Bitcoin threshold contracts. Election pair readings are available in Compare. Standard collection reads the named Federal Reserve calendar, BEA GDP overview or the fixed PCE overview for recognized Core PCE terms. The PCE overview is context; the exact monthly figure still needs its release. The optional scope adds the exact official Fed decision, GDP release or selected PCE/CPI monthly release when available. Core CPI collection retains terms only until you explicitly request BLS release evidence. A candle query plan does not fetch candles. Other contracts retain their venue text and explain what is missing.

Price for your size

Read YES and NO depth, then estimate buying or selling a number of shares.

An explicit read only. Changing the size does not create an order or start background collection.

Venue-provided conditions

What defines this contract

Description & declared source

This market will resolve based on OpenAI's market capitalization at the closing price on its first day of trading. If no IPO occurs by December 31, 2026, 11:59 PM ET, the market will resolve to "No IPO by December 31, 2026". Market capitalization expresses the monetary value of a company’s outstanding shares, stated in its pricing currency. It is calculated as the number of shares outstanding multiplied by the closing share price on the first trading day. If the relevant value falls exactly between two brackets, then this market will resolve to the higher range bracket. Resolution will be based on the primary exchange’s official listing page. In the event that the relevant figure is not displayed, another reliable source will be used. In the event of an interruption in the course of the normal trading session on OpenAI’s first day of trading (e.g., a circuit breaker or half-day), the market will resolve according to the official closing price of the abbreviated session. If no such official closing price is published, the market will resolve according to the next trading day on which an official closing price is published, treating that as the first day of trading for purposes of this market.
