How it works
- 1Pick an event
Choose a question, like where CPI lands or whether a company beats earnings.
- 2Choose Yes or No
Each share costs between 0 and 100 cents. That price is the market's odds.
- 3Wait for the result
A winning share pays $1. A losing one pays nothing. You can also sell before then.
The price is the odds
ExampleWill the Fed cut rates at its next meeting?
Yes 62¢
No 38¢
100 Yes shares
Costs $62
If Yes / if No
Pays $100 / $0
