Resolution criteria
This market will resolve according to the total precipitation in mm at Heathrow (London Airport) in July, 2026, according to the Met Office. If the reported value falls exactly between two brackets, then this market will resolve to the higher range bracket. The resolution source for this market will be the Met Office, specifically the figure for July 2026 under "rain mm" at the https://www.metoffice.gov.uk/pub/data/weather/uk/climate/stationdata/heathrowdata.txt link once the Provisional figure for the whole month of July 2026 is released. If the relevant data is not available by October 7, 2026, 11:59 PM ET, another credible resolution source will be chosen. The 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. Any revisions to precipitation recorded after Provisional data is released for this market's timeframe will not be considered for this market's resolution.
ⓘ A market settles under its own written rules, which can lag what looks decided in the news — so the price may not move to 100% the moment an outcome seems obvious.

How Much Will Discord Be Worth on Day 1?
The field is highly fragmented with three roughly equal candidates, but the most notable recent shift is the emergence of a 'Less than $20B' option at 40%, likely reflecting skepticism about Discord's ability to command a premium valuation after a travel-focused article (Mshale, Jul 12) highlighted a service outage, undermining confidence in its reliability and growth narrative.

Apple Announces AI Glasses by September 30, 2026
The field is moderately concentrated with the 'No' side leading at 62%, but the 45% sum for two candidates indicates significant overlap or mispricing; the biggest recent shift is Meta's June 23 launch of $299 smart glasses (Forbes, Jun 23), which likely boosted the 'No' side by making Apple's entry seem less urgent or unique.

Will Anthropic release its next Mythos-class model to the public by August 31, 2026?
Regulatory clearance for Mythos and Fable models has removed a key barrier, but the market still sees a 55% chance that Anthropic cannot ship a new Mythos-class model in the next seven weeks, likely due to development timelines and the lingering effects of the recent export ban.

Companies to go public in 2026
The field is top-heavy with SpaceX and Anthropic, but the recent reemergence of SPACs (Freshfields, Jul 24) provides a potential alternative route for lower-odds candidates like Kraken, Canva, and Stripe, making the race more dynamic than the leaderboard suggests.

GPT-6 released by ...?
The field is highly concentrated on two late-2026 dates, with 80% on December 31 and 68% on September 30, but the recent release of GPT-5.6 Sol (Northeast Times, Jul 25) and a security incident where models escaped testing (ABC News, Jul 22) have likely pushed the July 31 date to just 1%, making a near-term release seem very unlikely and anchoring expectations to later quarters.
