Dated base-rate sensitivity worksheet
This is reproducible arithmetic, not measured execution or a market-wide ranking. Kraken Pro and Gemini ActiveTrader base taker snapshots were checked October 24, 2026. Eligible tier, asset pair, funding rail and order size can change the result; a $100,000 trade need not remain in the illustrated base tier.
| Exact product | Amount USD | Execution USD | Spread USD | Funding / withdrawal USD | Total USD |
|---|---|---|---|---|---|
| Kraken Pro spot | 1,000 | 8.00 | 0.00 | 0 / 0 | 8.00 |
| Kraken Pro spot | 1,000 | 8.00 | 5.00 | 4 / 4 | 21.00 |
| Gemini ActiveTrader spot | 1,000 | 12.00 | 0.00 | 0 / 0 | 12.00 |
| Gemini ActiveTrader spot | 1,000 | 12.00 | 5.00 | 4 / 4 | 25.00 |
| Kraken Pro spot | 10,000 | 80.00 | 0.00 | 0 / 0 | 80.00 |
| Kraken Pro spot | 10,000 | 80.00 | 50.00 | 4 / 4 | 138.00 |
| Gemini ActiveTrader spot | 10,000 | 120.00 | 0.00 | 0 / 0 | 120.00 |
| Gemini ActiveTrader spot | 10,000 | 120.00 | 50.00 | 4 / 4 | 178.00 |
Reproduce each CSV row: amount × execution% / 100 + amount × spread% / 100 + funding USD + withdrawal USD. Percentages apply to the same USD amount. Example: $10,000 × 0.8% + $10,000 × 0.5% + $4 + $4 = $138. Hypothetical costs are not verified provider charges.
The next dates. The important details.
Next on the calendar: the October FOMC meeting
The Federal Reserve lists October 27–28 for its next meeting and December 8–9 for the final scheduled meeting of 2026. A calendar date is not a rate forecast.

Polymarket US’s standard taker coefficient is 0.0695 in its October 19 schedule; Table Tennis, combos and rebate tiers have separate treatment.

What is a prediction market?
A market for contracts tied to defined outcomes. Its prices can express expectations, while its rules determine what eventually gets paid.
Kalshi vs Polymarket US: costs, funding and rules
Both use event contracts, but the full comparison includes product identity, order execution, funding and exceptional settlement.
How Kalshi works: from a contract price to settlement
A contract has a price today and a defined payoff later. Understand the question, your total outlay and the loss scenario before interpreting its implied probability.
Same questions. Different platforms.
The product matters
more than the logo.
Start with access, contract rules and all-in cost. Keep Polymarket US separate from its international product.
See the comparison framework| Product | Normalised cost basis | Rule distinction |
|---|---|---|
| Kalshi | 100 × 50¢: $1.75 general taker model | Market-specific observation and lifecycle |
| Polymarket US | 100 × 50¢: $1.74 standard taker collection | US dollar account and US settlement rules |
| Novig | 10,000 cent units at 50%: $1.50 when charged | WHEN_LIVE games / ALWAYS specified futures |

Costs deserve a closer look.
Kalshi fees: formulas, funding and a full trade example
The published schedule separates general taker charges, market-specific maker charges, settlement and funding. Here are the numbers and their limits.
Polymarket fees: the US and international schedules
US standard taker fees, market exceptions, maker rebates and international coefficients belong in separate columns.
Kraken vs Coinbase: compare the spot products
Kraken publishes a numeric Pro schedule. Coinbase Advanced directs customers to their account-specific fee tier. Simple purchase pricing works differently on both.
