The 2 November contract defines the index measure and source hierarchy. Proxy instruments and intraday highs cannot silently replace that benchmark.

What the primary record establishes

CFTC record 65796, dated 27 October 2026, links to KalshiEX terms asking about the S&P 500 at the close on 2 November. That observation is still future as of this edition. CFTC product record 65796 — 27 October 2026 ↗

The terms use the official closing index value, measured to two decimal places. They distinguish that value from intraday highs or lows, indicative after-hours levels and prices of tracking products or derivatives. KalshiEX — S&P 500 close on 2 November 2026 ↗

What the distinction changes

The source hierarchy begins with S&P Dow Jones Indices. Seeing a similar number on another feed is not enough to ignore the hierarchy when sources conflict. KalshiEX — S&P 500 close on 2 November 2026 ↗

Comparison operators also matter: above is strict, whereas at least includes equality. A value equal to a strike can therefore produce different answers for differently worded questions.

What to check before drawing a conclusion

A hypothetical equality example explains arithmetic, not the actual 2 November close. Preserve the listed operator and rounding convention before deciding an outcome.

Read correction cutoffs and no-data provisions alongside the headline. A well-known index name does not make every price carrying that name the governing observation, and the filing is not a forecast or recommendation to trade.
