Which product answers your question?
For US dollar-account research, compare Kalshi with Polymarket US. The international Polymarket product has a different account, fee schedule and resolution system; it is context here, not a US trading alternative. A smaller fee does not compensate for a differently defined contract.
| Decision | Kalshi | Polymarket US | International context |
|---|---|---|---|
| Account / funding | USD; ACH and other documented rails | USD; cleared-fund and KYC workflow | Separate wallet/asset workflow; US access restricted |
| 100 × 50¢ taker example | $1.75 general model | $1.7375 raw; $1.74 half-even collection | Category schedule; not the US coefficient |
| Maker treatment | General zero unless scheduled | US maker/rebate tiers in US schedule | Separate international programme |
| Settlement evidence | Market-specific source/rules and lifecycle | US contract settlement/rules | International resolution docs |

Choose by contract and workflow
Kalshi is a useful research starting point for broad event-contract questions. Polymarket US is useful for readers who want its dollar-based order book and documented US funding workflow. Neither has been assigned a star rating or a universal winner. A particular contract’s definition and liquidity can matter more than a one-cent scheduled fee difference.
This is a US-product comparison. International Polymarket pricing, liquidity and wallet instructions are excluded from the US column.

The same $50 entry scenario
For 100 standard $1-payoff contracts at $0.50, Kalshi’s general M=1 taker fee is $1.75; Polymarket US’s standard taker fee is $1.7375 before its rounding rule, collected as $1.74. If they win, net proceeds above entry outlay are $48.25 and $48.26 before other costs. If they lose, losses are $51.75 and $51.74.
The Kalshi PDF is effective July 7 and the US schedule October 19, 2026. Special series, Table Tennis, combos, maker charges/rebates and funding can invalidate this simple pairing. Those numbers do not establish identical available contracts or executable prices.

Funding and access side by side
Kalshi’s schedule lists no Kalshi ACH deposit/withdrawal charge and up to 2% on card deposits. Polymarket US lists bank/card deposits clearing in 3–4 business days and wires in one, and returns withdrawals to the original funding source in FIFO order. It supports Apple Pay, PayPal, Venmo and certain USDC deposits as well.
Polymarket US requires KYC before funding/trading and restricts trading using confidential information or a position able to affect an outcome. The documents do not supply a definitive current state-by-state access matrix for every contract; that specific limit should not be confused with an unknown fee schedule.

Settlement and limits
The contract rulebook controls resolution source, observation window and alternative outcomes. US documentation explicitly allows market-defined alternative settlement. Similar market titles do not prove the same expiry or dispute terms.
An exit requires a counterparty at a real bid/ask, not merely a displayed historical last price. We compared published mechanics and costs; no account deposit or withdrawal benchmark was conducted. Readers who need a forecast rather than platform mechanics should distinguish implied probability from a guaranteed event likelihood.
