*I'm defining largest by the market cap (share value x outstanding shares). Companies that are not publicly traded (@PetroChina) do not qualify for this market. The companies that qualified for this market did so based on information from the end of 2023. If a company on this list is still one of the world's ten largest companies at EOY 2029, it resolves as Y. If not, then N.

For confirmation, I'll look for several reliable sources converging on the same answers. For this list I used Investopedia and Motley Fool.

Wikipedia's list excludes Saudi Aramco for having a free float of <15%, but I will not be using that consideration, which is why this list differs slightly.
