gameshows basically buy an insurance against larger winnings. it is then the banks job to figure out the probability of such large wins, and offer a premium to the gameshow they have to pay regardless what is won.
for small amounts (a few thousand) the gameshows itself can probably handle, for larger ones you need insurances (but are great advertisements). In the middle range you would basically still need insurance, but the premiums (and financial overhead) would probably be too high.
