How Does Polymarket Make Money?

When you buy a Yes share on Polymarket for 62 cents, the 62 cents does not go to Polymarket. It goes to whoever is on the other side of the trade, selling you that Yes share. Polymarket itself is not the counterparty. So the question of how it makes money is a question about what it charges for running the market, not about winning bets against its users.

The short answer: Polymarket charges a taker fee on most markets. On polymarket.com, its own fee documentation lists taker fees by category, with makers never charged and geopolitical markets fee-free; on Polymarket US, the CFTC-regulated venue, a published fee schedule took effect on 19 October 2026. Beyond trading fees, Intercontinental Exchange (ICE) has invested in Polymarket and distributes its data, though neither side has published what, if anything, ICE pays for that data.

Checked on 20 October 2026 against Polymarket's fee documentation, Polymarket US's fee schedule and rulebook, and ICE's announcements, all linked below. Fees change; the figure shown when you trade is the one that governs.

Traders trade with each other, not with the house

On a traditional sportsbook, you place a bet and the bookmaker is on the other side, and the book's margin is built into the odds it quotes. Polymarket works as an exchange instead: every filled trade matches a buyer against a seller, both of them traders, and the platform runs the order book and settles the contract when the event resolves. For the full mechanical walkthrough, our guide to how Polymarket works covers the order book and the resolution process.

That rules out the bookmaker's usual margin as a revenue source, because Polymarket is not pricing either side. What it can charge for is the trade itself, and since early 2026 it does.

What polymarket.com actually charges

Polymarket's fee documentation says it "charges a small taker fee on certain markets", and that "Makers are never charged fees. Only takers pay fees." A taker is the trader whose order fills against one already resting on the book; a maker is the trader whose resting order was filled.

The fee depends on the market's category and on the price. Polymarket gives the formula as fee = C × feeRate × p × (1 - p), where C is the number of shares and p the share price, so the fee is largest at a price of 50 cents and shrinks towards the extremes. The taker rates it lists are 0.07 for crypto; 0.05 for sports, economics, culture, weather, other markets and Combos; and 0.04 for finance, politics, mentions and tech. At 50 cents that comes to $1.75 per 100 shares in crypto and $1.25 in sports. Geopolitical and world events markets are the exception: Polymarket says they "are fee-free" and that it "does not charge fees or profit from trading activity on these markets."

This is recent. Polymarket's changelog shows taker fees switched on for 15-minute crypto markets on 5 January 2026, extended to all crypto markets in March, and widened to ten categories under "Fee Structure V2" on 30 March 2026, with geopolitical markets left fee-free; the sports rate rose from 0.03 to 0.05 on 10 July 2026.

Not all of the fee stays with Polymarket. Its documentation says taker fees fund a Maker Rebates programme, returning 20% of the fees in crypto markets, 15% in sports and 25% in the other fee-charging categories (none on Combos) to the makers whose orders filled, at Polymarket's discretion. A tiered Taker Rebate programme, live since 28 May 2026, pays part of a taker's fees back based on 30-day volume. Polymarket also pays out rather than collects in places: its help centre describes Holding Rewards at 3.25% annualised, "funded through the Polymarket Treasury".

Moving money in and out is not a revenue line. Polymarket says there are "no Polymarket fees to deposit or withdraw", though intermediaries such as Coinbase or MoonPay may charge their own, and its withdrawal page says "Polymarket does not charge withdrawal fees." Our walkthrough of placing your first prediction market trade covers what the all-in cost looks like for a new user.

Polymarket US is a different animal

Polymarket US is operated by QCX LLC, which Polymarket describes as "a CFTC-regulated Designated Contract Market"; it is a separate venue from polymarket.com. Its fee schedule, "Effective exchange-wide from 1:00 PM ET, Monday, October 19, 2026", uses the same shape of formula, Fee = Θ × C × p × (1 - p), with a taker coefficient of 0.0695, a maximum of $1.74 per 100 contracts at 50 cents. Table tennis markets use a higher coefficient of 0.10. Maker rebates are tiered by the previous month's maker volume and start at $10 million, and taker rebates of 3% to 30% start at $250,000 of monthly volume. Polymarket US says withdrawals are free. Its rulebook gives the exchange "sole authority to establish the amounts of any fees" and says it may post an updated fee schedule on its website; the schedule, not the rulebook, carries the numbers.

The two venues serve different people. Polymarket's help centre says "Polymarket.com is for international users, while US residents must use the Polymarket US app", and that "US users cannot deposit funds or place trades on the website." A visitor from the US sees a notice that trading is blocked on polymarket.com, with a prompt to switch to polymarket.us and an option to continue in view-only mode.

The other revenue levers

Polymarket's largest announced outside partner is ICE, the owner of the New York Stock Exchange. ICE's announcement of 7 October 2025 said it "will invest up to $2 billion in Polymarket, reflecting a valuation of approximately $8 billion pre-investment", that it "will become a global distributor of Polymarket's event-driven data", and that the two would partner on tokenisation. That $2 billion was a ceiling, not the sum paid then: ICE later said its initial direct investment, in October 2025, was $1 billion. On 11 February 2026 ICE said it now offers normalised data feeds of Polymarket's markets and "will become the exclusive provider of this data for institutional capital markets". On 27 March 2026 it said it had completed "a new $600 million direct cash investment" and expected to buy up to $40 million of Polymarket securities from existing holders, after which it "will have completed its obligations" under the arrangement. On ICE's own figures, that is $1.6 billion invested directly, plus up to $40 million of shares bought from existing holders, rather than $2 billion.

Two cautions belong beside that. An investment is funding, not revenue: it pays for the business rather than coming out of trading. And none of ICE's three releases states what ICE pays Polymarket for distributing its data, or whether the arrangement involves licence fees or a revenue share. Polymarket's terms of use do bar market data distributors and professional users from using its data "unless otherwise agreed to in writing by us", which is consistent with data being licensed, but the terms of any such agreement have not been published. Until they are, data licensing is a possible revenue line rather than a documented one.

Can you make money on Polymarket?

Yes, you can make money on Polymarket, and some users do. The more useful question is whether the typical user makes money, and our deeper read on who wins and who loses looks at how returns are spread. The intuition is familiar from any trading venue: prices are set by whoever is willing to take the other side, and a casual user clicking into a political market with a few hundred dollars is competing, on price, with traders who build models and refresh them.

That does not mean recreational trading is pointless, and some markets do misprice in ways a thoughtful outsider can see. But treat the question the way you would treat it for any exchange, not the way you would treat a scratchcard. Our realistic guide to making money on prediction markets is the honest version of the pitch.

How much money can you make on Polymarket?

There is no cap in the mechanical sense. A contract that resolves Yes pays out $1 per share, so a Yes share bought at 20 cents returns five times your stake if it resolves in your favour, and nothing if it does not. The taker fee comes off the trade when you buy or sell against a resting order, so on a fee-charging market it is part of the real after-cost return.

How to make money on Polymarket

The parts that are true and dull: do your own work on markets you understand, size positions you can afford to be wrong on, and read the resolution criteria of each contract before you buy. A market resolves on exactly the text written in its rules, not on the intuitive meaning of its headline.

The parts that are more useful: look for markets where your view differs from the price for a reason you can state, not just a feeling. Prefer markets with real liquidity, because a thin market costs you on entry and on exit. On a fee-charging market, check whether you are paying the taker fee; a resting order that someone else fills is not charged. And keep records, so you can tell an edge from a run of luck.

iPredicta's role

iPredicta tracks prices across the major prediction markets and publishes explainers and analysis of how they work. We do not operate a trading or betting product, we do not take positions, and nothing here is trading advice. For fees and charges, Polymarket's own documentation, linked above, is the authority.

Frequently asked questions

How does Polymarket make money?

Mainly through taker fees. On polymarket.com, Polymarket's fee documentation lists taker rates by category, from 0.04 to 0.07, applied as C × feeRate × p × (1 - p); makers are never charged, and geopolitical and world events markets are fee-free. Part of the fees goes back out through maker and taker rebate programmes. Polymarket US, the CFTC-regulated venue, charges takers under a fee schedule effective from 19 October 2026, with a coefficient of 0.0695. Deposits and withdrawals carry no Polymarket fee. Checked on 20 October 2026.

How to make money on Polymarket?

You make money on Polymarket by buying contracts for less than they turn out to be worth and holding, or selling, at a better price. In practice that means working on markets you understand, reading the resolution rules before you buy, trading markets with enough liquidity to exit, and knowing when you are paying the taker fee. Treat it as a competitive trading venue, not a casino.

Can you make money on Polymarket?

Yes, and some traders do consistently, but the other side of every trade is another trader, so a gain for one is a loss for another before fees. If you have a considered view on a specific market and the discipline to size positions sensibly, there is money to be made; if you trade casually on headlines, assume a durable profit is hard to come by.

What is Polymarket's revenue model?

Polymarket runs an exchange and charges takers a fee on most markets: by category on polymarket.com, with geopolitical markets fee-free, and under a published fee schedule on Polymarket US. It returns part of those fees through rebates. Separately, ICE has invested in Polymarket ($1 billion in October 2025 and a further $600 million in March 2026, under an arrangement of up to $2 billion announced in October 2025) and distributes its data, but neither has published the financial terms of the data arrangement.

How much money can you make on Polymarket?

There is no mechanical cap. A winning share pays $1, so a share bought at 20 cents returns five times your stake if it resolves in your favour, and nothing if it does not. On a fee-charging market the taker fee comes off the trade, so it belongs in the after-cost sum.
