Use the fee calculator carefully
ForecastIndex's fee calculator can model simple fee impact, but it does not replace the platform's current rules.
Fee research
Polymarket fees and practical trading costs
A Polymarket fee page should not stop at a single headline number. Readers need to think about spreads, liquidity, wallet flow, funding friction, and market-resolution risk before participating.

Polymarket Fees comparison table
Use the table as a routing tool, then verify current platform rules directly before signup or participation.
| Cost area | What to check | Why it matters |
| Explicit platform fees | Review current Polymarket terms directly. | Fee schedules can change. |
| Spread and liquidity | Compare bid/ask and market depth. | Thin markets can cost more than visible fees. |
| Wallet and funding flow | Check network and funding costs. | Crypto rails can add friction. |
| Resolution risk | Read exact market criteria. | Ambiguous criteria can change practical risk. |
Spreads can dominate cost
If a market is thin, buying and selling around the spread may matter more than a visible fee line.
