Generally, market criteria can be satisfied in one of three ways:
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the London City Airport Station, once finalized and available here: https://www.wunderground.com/history/daily/gb/london/EGLC.
Then only that source may be used for resolution. A consensus of reporting is not valid unless explicitly allowed in the market rules.
In some cases, markets may refer to a general standard like "major news outlets" as the basis for resolution, as seen in markets such as Will the Iranian regime fall by August 31? While this still requires independent corroboration, it narrows the range of acceptable sources to reputable, mainstream reporting.

Some markets may resolve based on public statements made by an official, through various forms of communication. For example:
Only tokens which are confirmed to have been launched by Kanye West, either through posts from official social media channels, or otherwise confirmed by public statements, will qualify.
The resolution source will be a consensus of credible reporting.
There are three resolution methods: posts from official social media, public statements such as interviews or press releases, and a consensus of credible reporting.
The resolution source in these markets may still be listed as a consensus of credible reporting, even if direct confirmation is allowed through other means.
In markets such as Will Kanye launch a coin in 2025? a consensus of credible reporting works as a backup method when there isn't a clear official source.
AskMagnus's social media activity cannot be relied upon as a resolution source. The team managing social channels is separate from the group responsible for issuing official clarifications, and the two are not always aligned. In some cases, official clarifications have directly contradicted earlier social posts. Social media posts are also not endorsements of how a market should resolve, even if they appear to express a position or highlight a particular outcome.
Users who relied on the tweet and took positions accordingly lost money when the market resolved in the opposite direction.
