Did Polymarket change the rules of a market?
Open the market on RulesWatch: its page lists every version of the rules I've recorded, with removed words in red and added words in green. If the page shows no changes, I haven't seen an edit since I started tracking it. Since I started recording on Oct 31, 2026, I recorded 7 edits: 7 on Polymarket (4 disputed outcomes, 3 date changes) and 0 on Kalshi.
How to check one market
- Press Ctrl K on any RulesWatch page and type a few words of the title, or a Kalshi ticker. The market page is at
/market/pm/<id>or/market/kalshi/<ticker>. - Read the change history. Each entry links to a change page with the word-level diff, the edit window and the Yes price before and after.
- To hear about the next edit, press Watch. See how alerts work.
To see every edit on both venues as they happen, use the changes feed.

What counts as a change
On Polymarket: the question, the rules text, the resolution source, the end date, and the UMA status that shows a disputed outcome. On Kalshi: the title, the outcome name, the primary and secondary rules, the close and expiration times and the early-close condition. Prices and volume are not changes.
Limits
- Neither venue publishes when it edited. I report the edit window: the time between my last check with the old text and the check that found the new one. The median window across all recorded edits is 2.3 h.
- A clarification posted only on Discord or X, with no edit to the market, is invisible to me until a trader links it on the market page.
- I start tracking a market once it has traded in the last 24 hours, or when someone watches it. The record starts on Oct 31, 2026; earlier edits aren't in it.
- The "clarification" label comes from the wording. The diff under it is exact.
More numbers are on the record; the method is on how it works.
Numbers as of Nov 1, 2026, 05:11 UTC; they refresh every 6 hours.
