The market resolves to Yes or No based on the CDC Measles (Rubeola) counter’s 2026 Total Cases figure, making the CDC the key reference point for the event prediction. If that source becomes unavailable, another credible source may be used, but only CDC-reported cases qualify for resolution. This matters because measles case counts reflect public health conditions, outbreak activity, and broader disease surveillance in the U.S. Market sentiment currently implies about a 65% probability of a Yes outcome, suggesting traders see the threshold as more likely than not to be met before the deadline. The event sits in the Science category and is tagged around measles, pandemics, and weather-related prediction market indexing. As the end date approaches, the forecast will depend on updated CDC reporting and any changes in case totals leading into the May 31 resolution time.","WEATHER","Science",[11,13,14,15],"Measles","Pandemics","Weather","https:\u002F\u002Fpolymarket-upload.s3.us-east-2.amazonaws.com\u002F1200-measles-cases-in-us-before-june-jPVnjl81lNC-.jpg",0.65,41769.07314,74334.21765800001,30083.59683,51545.740985000004,49201.5212334,true,false,"2026-04-27T21:56:11.705Z","2026-05-31T00:00:00.000Z","2026-04-24T19:07:36.532Z","2026-05-30T10:32:42.717Z","https:\u002F\u002Fpolymarket.com\u002Fevent\u002Fmeasles-cases-in-us-by-may-31?r=predstack",[31,32,33,34,35,36,37],"measles cases in u.s. by may 31?","measles cases in u.s. by may 31? prediction","measles cases in u.s. by may 31? odds","measles cases in u.s. by may 31? probability","weather prediction market","weather forecast","weather probability","2026-06-05T13:17:19.051Z","2026-05-30T10:42:59.250Z",0,[42,55,72],{"id":43,"title":44,"slug":45,"category":10,"subcategory":11,"tags":46,"probability":50,"createdAt":51,"updatedAt":52,"resolutionDate":26,"description":53,"summary":53,"volume1wk":54,"featured":24},"427938","Precipitation in Seoul in May?","precipitation-in-seoul-in-may",[11,15,47,48,49],"Precipitation","South Korea","Seoul",0.05,"2026-05-30T10:43:20.360Z","2026-05-30T10:30:37.772Z","This market will resolve according to the total precipitation in mm in Seoul in May, 2026, according to the Korea Meteorological Administration's information for the region\u002Fbranch of \"Seoul\".\n\nIf the reported value falls exactly between two brackets, then this market will resolve to the higher range bracket.\n\nThe resolution source for this market will be the Korea Meteorological Administration, specifically the figure for monthly precipitation in mm when the classification is set for \"ground\", the region\u002Fbranch is set for \"Seoul\", the element is set for \"precipitation\", and the period is set for the month of May at the https:\u002F\u002Fdata.kma.go.kr\u002Fclimate\u002FRankState\u002FselectRankStatisticsDivisionList.do link once the figure is finalized for the whole month of May 2026.\n\nIf the relevant data is not available by July 7, 2026, 11:59 PM ET, another credible resolution source will be chosen.\n\nThe resolution source for this market measures precipitation to 1 decimal place (e.g., 1.5), thus, this is the level of precision that will be used when resolving this market.
