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 May 1, 2027 (8.5%) to Jun 1, 2027 (12%), so the window opens on May 1, 2027. Quotes are bid/ask midpoints read on 27 October 2026; some strikes are quoted out of order, so the ladder is not strictly rising. Estimated contract-count-times-last-price volume across active strikes is about US$1,922 (31,540 contracts); this is not reported cash turnover.[1] Kalshi
On 27 October 2026 Kalshi put an official Stripe IPO confirmation at 1.5% before Nov 1, 2026, rising to 12% before Jun 1, 2027. The largest step in the ladder runs from May 1, 2027 to Jun 1, 2027 (8.5% to 12%), so that window is the market's most likely stretch; it is a bet on timing, not a listing date.
