The 2026 Nobel announcements begin October 5, when the Nobel Assembly at Karolinska Institutet names the Physiology or Medicine laureates. Seven days out, this guide re-runs two checks: the official schedule is unchanged, and every prize series now has an open Kalshi event, including Chemistry and Physiology or Medicine, which had none open on September 14. Every fact below is dated September 28, 2026.
Primary sources checked: the official 2026 announcement press release and prize announcement dates page (both re-checked 2026-09-28T05:33Z), the dated Kalshi public API snapshot (2026-09-28T05:42-05:45Z), and Kalshi's market rules guidance. This page verifies schedule and listing facts only, not odds, prices, volume, or fees.
The concrete news: the Kalshi set is complete. On September 14 the Chemistry and Physiology or Medicine series had zero open 2026 events; as of September 28 each has exactly one open event, 147 open single-name markets across all six series. The calendar pages are identical to the September 14 verification.
Related: the October 5-12 schedule overview and the per-day countdown guide.
All times come from the official pages re-checked at 2026-09-28T05:33Z, with announcements broadcast live on the Nobel Prize's official channels. "At the earliest" is the official qualifier: the live nobelprize.org prize pages control.
The ET conversion is CEST minus six hours. EU summer time ends October 25 and US daylight saving time ends November 1, 2026, both after announcement week, so the offset is stable for every day listed.
The dated snapshot shows exactly one open 2026 event per series, with verbatim titles, market counts, and close_time fields from the per-event queries.
Every market is a single-name contract. The first-listed market's rule text in each event, quoted verbatim: API listing order is not a ranking or favorites list.
Two structural notes: the Peace event includes organizations such as the ICRC and Reporters Without Borders, not only individuals, and the events list view returned mutually_exclusive=false for all six events on this date, reported as an observed field value only. Names appear solely as verbatim rule text, not predictions; the Nobel nomination process is confidential.
close_time is the trading deadline field in the API snapshot, not a settlement, resolution, or payout time. It must not be conflated with the nobelprize.org announcement times, and the dated comparison shows three patterns:
Settlement is governed by each contract's own rules on Kalshi, not by the announcement clock and not by this article. Read the live rules text before assuming anything about resolution timing.
This page is a static source check, not a live board; markets can close or change before announcement day:
Kalshi is a CFTC-regulated exchange, contracts settle in US dollars, and accounts require identity verification. Eligibility varies with jurisdiction and local law, so confirm it under the Member Agreement. Announcement-week notes are posted in the @Kalshi_market channel on Telegram; rules guidance sits at help.kalshi.com.
The 2026 Nobel announcements begin October 5 with Physiology or Medicine at 11:30 CEST at the earliest, then Physics on October 6, Chemistry on October 7, Literature on October 8, Peace on October 9, and Economic Sciences on October 12. "At the earliest" means the live nobelprize.org schedule controls.
The Norwegian Nobel Committee announces the Peace prize on Friday, October 9, 2026, at 11:00 CEST, which is 05:00 ET the same morning. The official pages list this time without the "at the earliest" qualifier, unlike the other prizes. Both clock changes fall after announcement week, so the offset holds.
As of the September 28, 2026 snapshot, each prize series has exactly one open Kalshi event: KXNOBELMED-26, KXNOBELPHYSICS-26, KXNOBELCHEM-26, KXNOBELLIT-26, KXNOBELPEACE-26, and KXNOBELECON-26, with 147 open single-name markets in total. No prices, volume, or fee data is verified here, and nothing promises a market stays open through announcement day. Confirm current availability and exact rules on kalshi.com.
Not necessarily. In the September 28 snapshot, Medicine and Chemistry close_time fields fall hours before their same-day announcements, Literature and Economics close after their announcement days, and Physics and Peace carry year-end values. close_time is a trading deadline field, not a settlement or payout time; settlement follows each contract's own Kalshi rules.
Not financial advice. Prediction-market trading is speculative, and you can lose money. Do your own research.
