Description
This event group determines which company will hold the third-largest market capitalization globally as of May 31, 2026, market close. Both Polymarket and Predict platforms offer identical binary outcome markets on the same resolution date and criteria, with a comprehensive list of named companies plus catch-all options.
PredictionHero - Resolution Divergence Alerts (RDA)
Unified Resolution Criteria (Consistent across platforms)
Both platforms use identical resolution criteria: third-largest global company by market cap on May 31, 2026, at market close, resolved via consensus of credible reporting.
Primary resolution logic:
Consensus of credible reporting (e.g., Bloomberg, Reuters, Yahoo Finance, or official exchange data as of May 31, 2026 market close)Core resolution logic:
- Rank all publicly traded companies globally by market capitalization as of May 31, 2026, market close
- Identify the company in the third position by market cap
- Exactly one binary market resolves YES; all others resolve NO
- If the third-ranked company is not explicitly listed, the catch-all "any other company" market (Polymarket only) resolves YES
- Ties at the third position are resolved by consensus of credible reporting sources
Edge cases & Clarifications:
- Tie for third place: In the event of a tie in market capitalization at the third position, consensus of credible reporting sources will determine which company is ranked third. If sources diverge, the most widely reported ranking by major financial data providers (Bloomberg, Reuters, Yahoo Finance) will prevail.
- Delisting or bankruptcy: If a company is delisted or enters bankruptcy before May 31, 2026, it is excluded from the ranking. The fourth-ranked company becomes third, and resolution proceeds accordingly.
- Merger or acquisition: If a company merges with or is acquired by another before May 31, 2026, the surviving entity's market cap is used for ranking purposes.
- Currency and exchange rate: Market cap is calculated in USD using exchange rates as of May 31, 2026, market close.
- Catch-all resolution (Polymarket): The "any other company" option resolves YES only if the third-largest company is not among the 28 explicitly named options on Polymarket.
Timing:
Resolution occurs on May 31, 2026, at market close (typically 4:00 PM ET for US exchanges). Consensus of credible reporting is applied immediately after market close data is available.Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.
