How much does Kalshi charge per trade?

Most Kalshi markets charge a taker fee of 0.07 × contracts × price × (1 − price), rounded up to the next cent — at most about 1.75¢ per contract at a 50¢ price. Resting orders are often free, though some markets have maker fees.

Does Polymarket charge fees?

Yes. Since 19 October 2026 the US app's standard taker fee is 0.0695 × contracts × price × (1 − price), rounded to the nearest cent — $1.74 on 100 contracts at 50¢ — and high-volume makers earn a tiered rebate. The international site has its own, category-based fee schedule.

Which prediction market has the lowest fees?

For pre-game sports, Novig charges nothing on straight trades. Elsewhere it depends on the price you buy at: Kalshi and Polymarket US are now almost identical, Robinhood adds its own commission to the exchange fee, and PredictIt's 10% profit fee is the most expensive on most winning trades.

Are there fees to deposit or withdraw?

Bank transfers are usually free. Card and Apple Pay deposits often cost around 2% on Kalshi. PredictIt scrapped its 5% withdrawal fee on 23 September 2026 — ACH and check withdrawals are now free. Crypto withdrawals pay network fees.

Prediction Market Fees Compared: Kalshi vs Polymarket (2026)

Fees on prediction markets look tiny — a cent here, a cent there. But every contract pays at most a dollar, so one cent is one percent. If you trade often, fees decide whether your hobby is cheap or expensive, and whether any edge you have survives. Here's the full comparison.

Fees change often. Figures are those published or widely reported in early October 2026; always check the platform's fee page before trading.

Maker vs taker: the one concept you need

A taker order fills immediately against an existing order (a "market" order, or a limit order at the current best price).
A maker order rests in the order book until someone else fills it.

Exchanges want resting orders because they create liquidity, so makers usually pay less, nothing, or even earn a rebate. If you're patient, using limit orders is the single easiest way to cut costs.

The comparison table

Platform	Taker trading fee	Maker	Notes
Kalshi	0.07 × C × P × (1−P) → max ~1.75¢	Often free; some markets charge	Card/Apple Pay deposits ~2%^[1]
Polymarket US	0.0695 × C × P × (1−P) since 19 Oct 2026 → max ~1.74¢ (table tennis 0.10; combos priced separately)	Tiered rebate by monthly maker volume (none below $10M; about 5-15% of the taker fee above that)	Rounded to the nearest cent^[2]
Robinhood (Rothera)	Commission 0.10 × C × P × (1−P) (0.05 with Gold), capped at 1¢ per contract + exchange fee of up to 1¢	—	Both charged on opening and closing trades; at mid prices the commission hits the cap, so Gold doesn't help there^[3]
Novig	Free pre-game; live 0.03 × P × (1−P)	Free	Parlay fee built into price^[4]
ProphetX	2% of net winnings	—	No fee on losing trades
FanDuel Predicts	~2% of potential payout (reported)	—	Also on cash-out
DraftKings Predictions	Built into quoted price	—	Total shown on ticket
Crypto.com	Per-contract fees, volume discounts	Lower	Check order screen
ForecastEx	$0.01 per contract per side (exchange fee)	—	IBKR broker commission depends on account; incentive coupon on open positions
PredictIt	10% of profits	—	Withdrawals free since 23 Sep 2026; cards ~3% after one free deposit^[6]

C = number of contracts, P = price in dollars.

Worked example: 100 contracts at 50¢

You buy 100 "Yes" contracts at 50¢ ($50) as a taker and hold to settlement, and you're right ($100 payout, $50 gross profit). Standard markets, no rebates or promotions.

Platform	Approx. fee	Net profit
Novig (pre-game)	$0.00	$50.00
Polymarket US	$1.74	$48.26
Kalshi	$1.75	$48.25
Robinhood	$1.00 commission + exchange fee (up to $1.00) = up to ~$2.00	from ~$48.00
FanDuel Predicts	~$2.00	~$48.00
ProphetX	~$1.00 (2% of $50)	~$49.00
PredictIt	$5.00 (10% of profit)	$45.00

The gaps look small on one trade. Over 200 trades a season, the difference between Novig and PredictIt is the difference between a cheap hobby and a costly one.

Worked example: a 90¢ favourite

Now buy 100 contracts at 90¢ ($90) and win ($10 gross profit).

Kalshi: 0.07 × 100 × 0.9 × 0.1 = $0.63 → keep $9.37.
Polymarket US: 0.0695 × 100 × 0.9 × 0.1 = $0.63 → keep $9.37.
Robinhood: commission $0.90 ($0.45 with Gold) + exchange fee up to $1.00 → keep about $8.10–8.55 (Robinhood's own worked example).
FanDuel Predicts (~2% of $100 payout): about $2.00 → keep $8.00.
PredictIt: 10% of $10 = $1.00 → keep $9.00.

Flat payout-based fees hurt most on favourites. Price-based formulas (Kalshi, Polymarket) are much gentler there.

Don't forget the spread

The bid–ask spread is a hidden cost. If "Yes" is 49¢ bid / 52¢ ask, buying at 52¢ and selling immediately loses 3¢ even before fees. On deep markets the spread is 1¢; on thin ones it can be 5¢ or more. Read our guide to liquidity and slippage.

Funding fees

Bank transfer (ACH): free almost everywhere.
Debit card / Apple Pay: around 2% on Kalshi; varies elsewhere.^[5]
Wire: may carry a fee for withdrawals.
Crypto: blockchain network fees.
PredictIt: ACH and check withdrawals free since 23 September 2026 (the old 5% fee is gone); card deposits ~3% after one fee-free deposit of up to $1,000.^[6]

Five ways to pay less

Post limit orders — be the maker.
Fund by bank transfer, not card.
Trade fewer, bigger-conviction positions instead of churning.
Hold to settlement when you can — closing early means paying a second fee.
Shop prices across two or three platforms before big trades.
