The Last Look…

Are prediction markets coming for macro?
Prediction markets have a habit of making people uncomfortable. That is partly because they look like gambling, partly because they sometimes are gambling, and partly because they do something financial markets have always claimed to do: put a price on the future. Since FX is the traditional home for macro trading, it’s perhaps worth taking a quick look at how the new craze could be relevant.
The recent debate around Kalshi, Polymarket and event contracts has mostly been framed around elections, sports and retail speculation. This is understandable, since (let’s face it) more people care about the World Cup than the price of the yen while the outcome of Bangladesh vs Australia is of relevance to more punters than housing stats or the new German ZEW print.
For FX markets, the more interesting question is not whether someone should be allowed to punt on who wins an election, but whether event contracts become another way of trading macro. Are prediction markets a threat or a potential source of trading signals?
A binary contract on whether the Fed cuts rates by a certain date, whether inflation lands above a given level, whether a government falls, whether tariffs are imposed, or whether a central bank intervenes is not obviously remote from the drivers of exchange rates. It is a simplified, all-or-nothing expression of the same themes that already move currencies every day.
Traders who need convincing that politics, policy and data releases matter should probably look for another job. Where prediction markets become worth a look is their ability to turn the event itself into the instrument.
Event contracts that are clean, intuitive and easy to understand have an obvious appeal. They strip out much of the complexity embedded in options, rates and FX derivatives and lower the barriers to entry: who needs market data when views can be formed from publicly-available information? And instead of asking how a policy surprise will travel through rates, volatility, risk appetite and positioning, a trader can simply buy or sell the probability of the event.
This is also exactly why regulators are circling. Recently, the FIA has urged the CFTC to retain the traditional DCM, FCM and DCO structure for leveraged event contracts, limit trading and clearing to contracts that can demonstrate compliance with core principles, consider whether a separate default fund may be needed, and address insider trading, conflicts of interest and settlement finality.
The Atlantic Council has made a different but related point. Prediction markets can be useful, but once their prices are treated by media, investors or policymakers as quasi-official signals, they become part of the information environment and cause issues related to market abuse: thin markets can be nudged, price moves can be amplified and in doing so, a market can become both a forecast and a message. That should sound familiar to anyone in FX.
Today, it’s currency markets that are the most vulnerable to narrative cascades, the first to react and the purest expression of markets incorporating new information into prices. A rumour of intervention, a headline on tariffs, a leaked policy story or a sudden move in rates can ripple through the market before anyone has worked out whether it is true. Add event contracts into that ecosystem and the price of a prediction could itself become a tradable signal. This makes prediction markets potentially very powerful.
Europe’s experience is also a warning. ESMA banned the marketing, distribution and sale of binary options to retail investors in 2018, citing investor protection concerns. The Atlantic Council argues that the US could learn from that approach by asking who should have access to binary event contracts, rather than only debating whether the products should exist. That distinction matters for FX.
If a thinly traded market on a central bank action moves sharply, will FX traders treat it as information?
There is a plausible institutional use case for event contracts linked to economic and policy outcomes. A corporate treasurer exposed to tariff risk, an asset manager worried about election-driven currency volatility, or a macro fund hedging a central bank outcome may see value in a clean binary hedge. But that is not the same thing as saying every retail user should be invited to trade every geopolitical headline in real time.
FX is already one of the largest and most liquid markets in the world, with daily turnover reaching $9.6 trillion in April 2025. It does not lack instruments. It has spot, forwards, swaps, futures, options and NDFs. The case for prediction markets in FX therefore cannot be that the market needs another toy.
The case is narrower: they may offer a more direct way to isolate event risk. This could be useful – or dangerous. The danger is not just that retail traders lose money, although many will. Nor is it only that insiders may know more than the rest of the market, although that risk is real. The larger issue is that macro event contracts could blur the line between pricing probability and shaping probability.
If a thinly traded market on a central bank action moves sharply, will FX traders treat it as information? If a prediction market implies a rising chance of capital controls, will that feed into spot pressure? If a contract on intervention is pushed around by a concentrated position, does it become a signal, a trade, or an attempted market-moving headline? These are real questions for a market that already lives on expectations.
Prediction markets are often touted as democratised forecasting. Sometimes they are, but information is certainly not evenly distributed, liquidity is not always deep and incentives are rarely pure.
Still, from an FX perspective, is dismissal the right response? Maybe not. A better route might be to treat event contracts as a market structure issue. Who can trade them? How are contracts designed? Who decides settlement? How are conflicts managed? What surveillance exists around informed trading? How are prices presented to the public? And what happens when the event being traded is itself capable of moving currencies?
It remains highly unlikely that institutional investors will rush to express their views in prediction markets (for now) but even so, these new market places may yet become another useful layer in the macro toolkit. For FX, they could help isolate policy risk, geopolitical risk and data risk in a way existing instruments do not always do cleanly.
In FX, the future is already traded every day. Prediction markets just make that more explicit.
Worth a second look? Liquidity will tell.
