 is #1 on Manifold leaderboard by profit: 

But a mystery remains: how much actual real-world money do they have?

All currencies and stocks converted to USD using Google at close time.

Including: cash, bank accounts, stocks, cryptocurrency, property with no other significant usage that could be easily exchanged for money (e.g. collectibles).

Not including: mana, other property, loans/credit.

Allowed direct market manipulation strategies for 

 includes: to spend or receive money (e.g., but not limited to: from their job, selling something, receiving donations, etc.)

In case if they lend money to someone, it still counts towards the total if it happened after market open and doesn't count if it happened before market open, to prevent market manipulation.

If I didn't think about some clause, please clarify in comments and I will update the description, the spirit of this market is to get an honest number, i.e. the one that would be considered as such by most people.

If you are unsure about something (what counts and what not) – please ask in comments.

Allowed direct market manipulation for everyone else would be to donate money to 

 for a number (at close time) and resolve to that. If I don't get a response (that seems honest and a non-joke), this market will resolve N/A.

If the number falls out of bounds, I will resolve to min or max boundary accordingly.

Market might be closed/resolved earlier than the specified close time if I feel like it and will get an answer, I just don't know what duration to choose yet. The specified close time is the max boundary.
