They don't need to donate their fortune by then, just someone who is significantly involved in the EA movement who commits to donating a significant portion of their fortune to EA causes. Forbes must estimate their net worth to be greater than $1B.
Could you give some list of people who currently qualify? A non-exhaustive list is OK, just to check e.g. if people such as Vitalik Buterin (if net worth $1B), Patrick Collison, or Bill Gates count for the purposes of the question.
@dp none of those would qualify. Dustin Moskovitz, Jaan Tallinn would currently count. SBF, Gary Wang, Caroline Ellison would have counted were it not for the FTX situation. Furthermore, "one unknown person doing earning to give" would count if it was confirmed that this person was a billionaire and was donating a significant fraction to EA causes but just wished to stay anonymous (but this guy becoming known would not count as a new billionaire).

@MarcusAbramovitch stupid nitpick: sbf and Ellison wouldn't count "were it not for the ftx situation" because the scam is how they became paper-billionaires in the first place.
