Prediction markets vs binary options — why they are not the same thing

If you describe a prediction market contract to someone in finance, there is a good chance they will say "so, a binary option". The comparison is understandable: both instruments pay a fixed amount if an event happens and nothing if it does not. But the resemblance is superficial. The two differ in who takes the other side, where the price comes from, and — importantly for anyone in Europe — how regulators treat them.

Here is the plain-English version.

What a binary option actually is

A binary option is a contract sold by a broker. You pick an underlying — usually a currency pair, an index or a commodity — and a strike, and you predict whether the price will be above or below that level at a fixed moment, often only minutes away. If you are right you receive a preset payout; if you are wrong you lose your whole stake.

Two features define the product. First, the counterparty is the broker itself, not another trader. The firm that sold you the contract profits when you lose. Second, the payout is asymmetric by design: a typical retail binary option paid something like 70–85% of the stake on a win against a 100% loss on a miss. Repeated over many trades, that asymmetry means a trader has to be right well over half the time simply to break even.

Add very short expiries — sometimes 60 seconds — and you get an instrument that behaves less like an investment and more like a slot machine with a chart attached.

Why the EU banned them for retail clients

This is not a matter of opinion. In 2018 ESMA, the EU securities regulator, used its product-intervention powers to temporarily prohibit the marketing, distribution and sale of binary options to retail clients across the Union. ESMA renewed the measure several times, then stopped renewing it in 2019 — not because the concern went away, but because national regulators in the member states had by then adopted their own permanent bans covering the same ground.

The stated reasons were the product's complexity, its lack of any obvious investment purpose, the structural conflict between broker and client, and consistent evidence that the large majority of retail accounts lost money. Aggressive cross-border marketing by offshore firms was a large part of the picture.

So if you are a retail client in the EU today and you find a site offering you binary options, the relevant question is not "is this a good trade" but "why is this firm able to offer me a product my regulator prohibited".

Where a prediction market differs

A prediction market contract also settles at a fixed value — typically 100¢ if the event happens, 0¢ if it does not. That is where the similarity stops.

You trade against other people. There is no broker on the other side of your position hoping you are wrong. Prices form in an order book where participants buy and sell from each other. The platform runs the venue; it does not take your bet. This is the same structural point that separates prediction markets from sportsbooks, which we cover in prediction markets vs sports betting.

The payout is not shaded against you. Buy a contract at 40¢ and it settles at 100¢, you receive 100¢ — the full amount, not 78% of it. Your entry price is your odds, and you chose it. Nobody quietly clipped the payout.

The price means something. Because it is set by supply and demand rather than by a broker's pricing engine, a prediction market price reads directly as a probability. A contract at 65¢ is the crowd's estimate that the event is about 65% likely. Binary option quotes carry no comparable public signal — they are one firm's numbers, shown to one customer.

The horizon is real. Prediction markets are usually built around events with genuine informational content: an election, a central bank decision, a tournament, an inflation print. Sixty-second price flips on EUR/USD are not forecasting questions. They are noise, sold as a product.

The overlap regulators are still working through

None of this means prediction markets sit outside regulation. European supervisors have been active on exactly this question, including a joint warning from nine gambling regulators earlier this month about unlicensed platforms — we wrote about it in nine European regulators just warned about prediction markets. Part of the live debate is whether certain event contracts fall within the existing binary options restrictions, and the answer will differ by product and by jurisdiction.

The honest summary: "prediction market" is a description of market structure, not a legal exemption. A well-designed, licensed, exchange-style market is a different animal from a broker-sold binary option — but the label alone does not make a platform legitimate. Check who holds the licence, where the platform is authorised, and whether it will actually accept you as a resident of your country.

The distinction worth remembering

A binary option asks you to beat a house that set the odds and pays you less than you risked. A prediction market asks you to disagree with a crowd at a price you can see, and pays the full amount if you are right. Those are different games, even though the payout diagram looks the same.

The cheapest way to feel that difference is to trade it without money at stake. On Outcomer you can buy and sell real markets with virtual money — watch a price move on news, sell before resolution, and see how the probability behaves. Nothing to lose except a few wrong forecasts.
