I don't know how accurate this is but I read this
Do the losing teams get any cash prizes?
Yes, the losing teams do get small cash prizes, staggered according to how long the team stayed in the race. For some reason, these amounts are kept very secret (much more so than the Sequesterville locations), but we have heard rumors that the second-place prize for some seasons has been $25,000 or $50,000, and third place was $10,000 or $25,000.
According to Aaron of TAR6, here's the prize breakdown:
1st- 1,000,000
2nd- 25,000
3rd- 10,000
4th- 7,000
5th- 6,000
6th- 5,000
7th- 4,000
8th- 3,500
9th- 3,000
10th- 2,500
11th- 1,500
This is, however, unverified
At the top it has this so the information is very dated

Please note, this informaion should be correct as of TAR6
