You might remember Warren Buffett offering a billion USD to people who could perfectly predict something called 'March Madness'.
I don't know the details, but it seems to be some kind of American sporting event, and getting everything right was exceedingly unlikely.
You can buy bespoke insurance for this kind of thing. See https://en.wikipedia.org/wiki/Prize_indemnity_insurance
By your logic, Warren Buffett should have been able to buy spend just a dollar or so to buy insurance against someone getting everything right, shouldn't he? After all, the chances were exceedingly small and competition would have driven down the insurance premium?
