How this market settles
What could still go wrong
- 'Any point between market creation and December 31, 2026' implies continuous monitoring or periodic checks — the frequency and exact timing of checks is not fully specified, creating potential disputes about whether a transient top-3 appearance counts.
- Definition of 'Chinese company' is non-exhaustive ('include but are not limited to'), leaving ambiguity for companies not listed that may or may not qualify.
- 'Primarily owned or operating within the Chinese technology ecosystem' is subjective and could be disputed for companies with mixed ownership or international operations.
- If the leaderboard becomes permanently unavailable, the fallback 'another resolution source' is undefined, introducing uncertainty about what source would be used.
- The end date in the metadata (2027-01-01T04:59:00Z) corresponds to December 31, 2026, 11:59 PM ET, but timezone handling and daylight saving time transitions could create minor ambiguity.
- Granular/unrounded Arena score values used for tiebreaking may not be publicly visible, creating potential transparency issues in tie resolution.
