Agreed, Eric. Any fund of this type must be made up of stable investments & be able to account for inflation. In reality, $1,000,000 doesn't fund a $100k tourney every year. Due to the lower interest of said stable investments & adding some of the earned interest back in to help balance out inflation, the $1,000,000 actually funds a $50k tourney.
Then, as LC3 mentioned, there has to be someone to oversee the endowment/annuity & they'll want to be paid for those services. In addition, I'd guess the fund needs to cover the tournament expenses as well. So, to get your $100k tournament, you would need roughly $2.5M to $3M in principal.
As an idea, it sounds great. The trouble will be raising the initial capital, then finding someone to oversee it.
