Re: “Who currently owns the 36 million shares?”
Good question. Most likely, the corporation itself.
If Trump failed to meet the bonus criteria, the shares could be sold on the open market - or - assimilated back into the corporation.
Since the existence - and possible distribution - of the shares was public knowledge, you have to assume that all subsequent investors - those currently buying and selling shares of DJT - have factored the potential value - or - loss of value - into the price they are willing to pay for shares that are already trading.
“If Trump failed to meet the bonus criteria, the shares could be sold on the open market - or - assimilated back into the corporation.”
If so, the shares would never be issued.

Or never issued.
