| Question | Why it matters | ForecastIndex page |
| Am I eligible? | Availability differs by platform and jurisdiction. | /platforms/ |
| What market type do I need? | Crypto-native, regulated, political, and community platforms are different. | /best-prediction-markets/ |
| What are the costs? | Fees, spreads, funding, and withdrawal friction can all matter. | /guides/prediction-market-fees/ |

Then compare market coverage
A platform with many markets may still be a poor fit if your specific category is thin or hard to resolve.
Calculate practical cost
Direct fees are only part of the cost. Spreads, funding, wallet costs, and liquidity can matter more.
Use referral links carefully
ForecastIndex may earn a referral benefit, but readers should still compare alternatives and verify rules directly.
Disclosed referral link
Review the Polymarket evidence for how to choose a prediction market, then compare alternatives.

What should I check first?
Check eligibility and market rules first. Fees and app experience matter only if you can actually use the platform.
Why does ForecastIndex recommend Polymarket often?
Polymarket is the configured primary referral platform and a strong crypto-native reference where the reader is eligible and the use case fits.
