2nd largest company end of May?

Resolution Criteria

This market will resolve to the second-largest company in the world by market cap on May 31, 2026, as of market close. The resolution source for this market will be a consensus of credible reporting.

Alphabet is the heaviest-backed outcome to be the second-largest company in the world by market capitalisation at the close of 31 May 2026, with Apple the only other contender attracting meaningful volume. The market across 29 possible outcomes is sharply concentrated on these two names. Resolution is based on market-cap rankings at the close of 31 May 2026, verified by a consensus of credible financial reporting.

Market structure

Twenty-nine companies are listed as possible outcomes, but volume is heavily concentrated on just two: Alphabet and Apple. All other named outcomes — including NVIDIA, Amazon, Microsoft, Tesla, Broadcom, and Saudi Aramco — attract negligible trading interest. Resolution uses market capitalisation at the close of 31 May 2026 as the ranking metric, confirmed by a consensus of credible reporting. No fallback deadline is specified beyond the resolution date itself.

Background

The ranking of the world's largest companies by market capitalisation shifts frequently, driven by earnings cycles, macroeconomic conditions, and sector sentiment. As of early 2025, the top five positions have been contested primarily by Apple, Microsoft, NVIDIA, Alphabet, and Amazon, with NVIDIA's rapid ascent during the artificial-intelligence investment boom reshaping the order that had been relatively stable for several years. The identity of the first-place holder — typically Apple or Microsoft — directly determines which company occupies second, making this market structurally dependent on concurrent movements across several mega-cap technology stocks. Alphabet's Google parent has historically held positions between second and fifth in global rankings.

Key factors

The outcome depends on the relative market capitalisation of all major technology and energy companies at a single point in time — market close on 31 May 2026. Key variables include quarterly earnings results from Apple, Alphabet, Microsoft, NVIDIA, and Amazon between now and that date, which can cause large single-day valuation swings. Broader equity market conditions, interest rate decisions by central banks, and macroeconomic data releases affect the entire technology sector simultaneously, compressing or widening gaps between companies. Currency movements matter for companies with significant international revenue when valuations are compared in US dollar terms. Regulatory developments — particularly antitrust proceedings in the United States and European Union affecting Alphabet's advertising and search businesses — could produce material valuation changes. Any significant share buyback programmes or index rebalancing events among the top companies could also shift relative rankings in the weeks approaching the resolution date.
