Estimated: a "by when" market with no scheduled event behind it. The largest step between consecutive strikes (taking the highest quote seen so far where a later strike is quoted lower) is Apr 1, 2027 (11%) to May 1, 2027 (14%), so the window opens on Apr 1, 2027. Quotes are bid/ask midpoints read on 27 October 2026. Estimated contract-count-times-last-price volume across active strikes is about US$139 (1,384 contracts); this is not reported cash turnover.[1] Kalshi
On 27 October 2026 Kalshi put an official Rippling IPO confirmation at 2.5% before Nov 1, 2026, rising to 15% before Jun 1, 2027.
