Lowest-fee prediction markets in 2026: what each platform charges
7 min read
By Turk, founding engineer at Totalis. We build the combo platform for prediction markets on Hyperliquid.
No prediction market charges nothing on every trade, but the gap is wide: a taker buying 100 shares at 50 cents pays anywhere from nothing at entry to 2.38 dollars, depending on the venue. We build Totalis, whose own fee on a single is 0.1%, and we show below where it is cheaper and where it isn't. Totalis is not available in the US.

The short answer#
The lowest-fee prediction markets in 2026 are Totalis for singles and Combos outside the US, at 0.1% plus Hyperliquid's fee on a single; Hyperliquid itself if you skip the app's 0.1%; Novig for pre-game sports in the US; Polymarket for limit orders, which pay no fee there; and SX Bet if you'd rather pay only on winners.
How do prediction market fees work?#
- Takers pay, makers often don't. An order that fills against the book pays the taker fee; one that rests usually pays less or nothing.
- Most fees follow p × (1 − p), so they peak at 50 cents and shrink near 0 and 1. Totalis instead charges a flat 0.1% on singles, and SX Bet a share of a winner's profit.
- The spread is a cost too. On a thin book it can cost more than the fee.

What a Totalis Combo costs: a worked example#
Say you stake 100 USDC on a three-leg Combo and makers quote a 400 USDC payout (an illustrative quote). Per the Totalis fees and limits page, the entry fee is 1.5 USDC, leaving a net stake of 98.5, and a win pays 1% of what the position settles at above that.
| Result | Settles at | Profit fee | You receive | Total fees |
|---|---|---|---|---|
| Every leg wins | 400 | 3.015 | 396.985 | 4.515 |
| One leg resolves at 0.5, the rest win | 200 | 1.015 | 198.985 | 2.515 |
| One leg resolves at 0.2, the rest win | 80 | None | 80 | 1.5 |
| Any leg loses | 0 | None | 0 | 1.5 |
The same 4x position elsewhere, fees only, for 400 contracts at a price of 0.25:
| Platform | If it loses | If it wins |
|---|---|---|
| Totalis | 1.50 | 4.515 |
| SX Bet | 0 | 15.00 |
| Polymarket | 3.75 | 3.75 |
| Polymarket US, lowest volume tier | 9.02 | 9.02 |
Totalis isn't cheapest in either column: SX Bet charges nothing on a loss, Polymarket less on a win. If the 4x price is fair, the position wins one time in four, and Totalis's fee averages about 2.25 USDC against 3.75 on Polymarket and SX Bet. The maker's quote matters more than any fee (how multi-leg payouts are priced).
1. Totalis#
Overview: A prediction market app on Hyperliquid that trades HIP-4 outcome markets as singles on the HyperCore order book, or as Combos of 2 to 5 legs that makers quote and the Totalis vault on HyperEVM settles.
Fees: Singles pay a 0.1% builder fee on filled value, buy or sell, plus Hyperliquid's outcome fee; a new account's first buy skips the builder fee. Combos pay 1.5% on entry and 1% of profit. Totalis charges no deposit or withdrawal fee.
Cheapest for: Taker singles at most prices (near 0.01 or 0.99, p × (1 − p) schedules fall below 0.1%), and Combos averaged over wins and losses.
Costs more for: Limit orders, which pay nothing on Polymarket or SX Bet, and losing Combos, which keep the entry fee. You can ask makers to buy a Combo back early, but an offer isn't assured.
Availability: Not available to US persons or anyone in the US, per the Totalis terms of service; signing up takes an invite code. Fewer markets than Polymarket or Kalshi, and a 1,000 USDC maximum stake.
2. Hyperliquid#
Overview: The exchange whose HIP-4 outcome markets Totalis trades.
Fees: Hyperliquid's own pages don't agree. Its HIP-4 page still says outcome fees are zero for initial testing, while its fees page says outcome trading charges only on closing or settling, with no rebates. A Hyperliquid app announcement gives one rate: a tier 0 taker pays nothing to open and 0.07% to close. Your rate depends on your tier and the market (Hyperliquid fees).
Cheapest for: Traders who place orders on Hyperliquid themselves and pay no builder fee (how to trade on Hyperliquid's Outcomes page).
Costs more for: Anyone who wants Combos; Hyperliquid has none.
Availability: Its interface terms exclude the US and Ontario.
3. Polymarket#
Fees: A taker rate from 0.07 on crypto to 0 on geopolitics markets; per its fee page, Polymarket charges no fee on geopolitics trades and none to deposit or withdraw USDC, though intermediaries may. Makers pay nothing.
Cheapest for: Limit orders, and geopolitics markets.
Costs more for: Crypto takers, at 1.75 per 100 shares at 0.50; bitcoin price prediction markets compares the crypto venues.
Availability: No new positions from the US, the UK and others. Polymarket's pages conflict on exits: its developer geoblock page calls them close-only, its help center, updated 29 October 2026, completely restricted.
4. Kalshi#
Fees: Kalshi charges on a contract's expected earnings. Its fee schedule sets 0.07 × C × p(1 − p) for takers, maker fees on some markets and no settlement fee. Combo takers pay the taker fee and accepted quoters the maker fee, per its rule filing with the CFTC.
Cheapest for: Resting orders on markets without maker fees.
Costs more for: Takers near 50 cents.
Availability: The US and many countries; its Member Agreement bars the UK, Canada, Australia, India and others (Kalshi alternatives).
5. Polymarket US#
Fees: Per its fee schedule, a taker coefficient of 0.095 below 10,000 dollars of 30-day volume, falling to 0.0695; new accounts pay 0.0695 for their first seven days. From 11 November 2026 the combo fee is C × p × [Θ(1 − p) + 0.06(1 − p)⁴].
Cheapest for: High-volume US traders.
Costs more for: New and low-volume takers, and combos.
Availability: The US, with state restrictions. As of 11 November 2026 its iPhone listing says trading is unavailable in Nevada, and under an agreement with Michigan it stops new sports contracts there and closes remaining sports positions by 25 November.
6. SX Bet#
Fees: Per its fee page, takers pay 1% of net profit and multi-leg takers 5% of profit, on winners only; makers pay 0%.
Cheapest for: Makers, and takers whose positions lose.
Costs more for: Winning multi-leg positions.
Availability: Its terms exclude residents of the US, the UK, Australia, France, Germany and Ontario, among others.
Other options. In the US, Novig charges no fee on pre-game straight trades or maker fills, and is unavailable in Nevada, Arizona and Michigan. Robinhood caps its commission at 0.01 per contract. Outside the US, Limitless and Predict.fun charge makers nothing; Limitless Packs build a 10% fee into the multiplier. Limitless's terms bar the US, Ontario and Alberta, and Predict.fun's the US, the UK and France, among others.
Does any prediction market charge zero fees?#
Not on every trade. Per their own fee pages, several charge nothing on specific orders: makers on Polymarket, Limitless, Predict.fun, SX Bet and Novig, and on Kalshi markets without maker fees; Polymarket's geopolitics markets; Novig's pre-game straight trades; and opening a position on Hyperliquid.

How we evaluated these platforms#
We compared taker fees, maker fees, combo fees and availability, using each platform's own fee page, terms or help centre, verified on 8 to 10 November 2026. We build Totalis.
Verdict#
If you're outside the US and want low fees on singles and Combos, choose Totalis and compare a Combo quote on Totalis. Without an app, Hyperliquid; for US pre-game sports, Novig; for limit orders, Polymarket; to pay only on winners, SX Bet.

FAQ#
Which is cheaper, Kalshi or Polymarket?#
For a taker at 50 cents, Polymarket on most categories: per 100 shares, 0.75 for sampled full-game NFL markets and 1.25 at the documented 0.05 sports rate, against Kalshi's 1.75. Polymarket crypto markets cost the same as Kalshi, and makers pay nothing on Polymarket.
Do you pay fees on a losing trade?#
On most venues, yes: the fee is charged when the order fills. SX Bet charges only winners, and Totalis keeps a Combo's 1.5% entry fee but takes no profit fee on a loss.
Do prediction markets charge deposit or withdrawal fees?#
Totalis and Polymarket charge none of their own; Kalshi charges none on ACH transfers but up to 2% on card deposits. Card processors and bridges can add theirs, and depositing to Hyperliquid covers its activation fee.
