This question will not be affected by any name changes.

If companies merge with another company valued at least 20% of their own market cap, they will be resolved as "N/A" and newly created. However, if they acquire a company or merge with smaller companies, this will not affect the resolution criteria.

In the case of a split, both splits will count for the future of the question, but the larger split will be checked at the end of the year. For example, if Meta splits into Facebook and Instagram and neither of these two companies is in the Top 10, the question will resolve as NO.

I will resolve any company created multiple times "N/A". Any company not in the Top 50 [updated January 2nd 2024, before Top 100] at the time of creation according to 

 will be resolved as "N/A", as I suspect these are created to manipulate league results, unlesss you can make a good point in the comments. [added January 2nd 2024]

This question will close on December 31, 2024, at 23:59 UTC.

If you have any questions or if any scenarios are unclear, please ask beforehand. Otherwise, I will use my best judgment to resolve this question. I might seek input from others if I feel too biased. I will bet in this market.
