Reporting from ESPN alone would not satisfy the source requirement. ### Review the evidence Do not rely only on headlines, summaries, or another user's verification. Review the underlying evidence yourself. If you're unsure, discuss it with others before treating the proposal as correct. *Example*: In *Will Trump say "Zohran" or "Mamdani" this week? (November 3–9)*, traders disagreed over what Trump said. One user claimed he said "Zohran," but others reviewed the evidence and found otherwise. ### Consider the timing of evidence Only consider information that was publicly available when the proposal was submitted. *Example*: In *Will Trump endorse Andrew Cuomo for NYC Mayor?*, a Yes proposal was later disputed because the available reporting did not yet satisfy the market's consensus requirement. ### Use the market odds as a sanity check If the Polymarket odds strongly disagree with the proposed outcome, take that as a reason to investigate further. Market odds are not evidence and should not determine the resolution. *Example*: If a Yes proposal has been submitted but the market is still trading at 50¢, it may suggest the outcome needs further review. ### Prioritize proposals about to finalize Consider prioritizing proposals whose challenge periods are about to end. *Example*: In the [UMA Oracle](https://oracle.uma.xyz/), prioritize proposals that are closer to the end of their challenge period.
