Prediction market on metaculus. The 27th Arabian Gulf Cup ("Khaleeji 27") is a biennial football tournament for the eight members of the Gulf Football Federation, hosted in Jeddah, Saudi Arabia, from 23 September to 6 October 2026. Group A comprises Saudi Arabia (hosts), Iraq, Oman, and Kuwait; Group B comprises Qatar, UAE, Bahrain, and Yemen. The top two teams from each group advance to the semi-finals. Group stage matchday 3 concludes on 29–30 September 2026, after which the semi-final pairings are confirmed. Both semi-finals are played on 3 October 2026: Semi-final 1 (Group A winner vs. Group B runner-up) at 18:00 UTC+3 (7:00 PM local) at Al-Inma Stadium, King Abdullah Sports City; Semi-final 2 (Group B winner vs. Group A runner-up) at 21:30 UTC+3 at Prince Abdullah Al-Faisal Sports City. The final is on 6 October 2026. In knockout football, if the score is level after 90 minutes plus stoppage time, the match proceeds to 30 minutes of extra time, and if still level, to a penalty shootout. Penalty shootouts are common in tight international knockout football: with two evenly-matched semi-finals between regional rivals, the probability that at least one goes to penalties is materially uncertain. Historically, Gulf Cup and comparable regional knockout ties have gone to penalties at a meaningful rate. As of 18 September 2026, teams have arrived in Jeddah and the tournament is about to begin; the specific semi-finalists are not yet determined. `{"format": "llm_question", "info": {"sdk_version": "0.6.0", "rating": {"quality": 3, "ambiguity": 4, "resolvability": 4, "passes": true}}}`
