Betting Exchange Decline: British Market Undergoes Dramatic Shift

The glory days of British betting exchanges appear to be over for now. What was once hailed as the revolution of betting is increasingly losing relevance in its home country, the United Kingdom. The Gambling Commission's annual report for the 2025/2026 period paints a grim picture for providers such as Betfair Exchange, Matchbook, and Smarkets. While the overall digital sports betting market is flourishing, peer-to-peer platforms are being relegated to a niche existence. The Gross Gambling Yield (GGY) in this sector has plummeted, accounting for only a tiny fraction of the total market.

Interestingly, this decline is occurring at the exact moment when a very similar product is experiencing a massive rise on the other side of the Atlantic. In the US, so-called prediction markets are booming, where users trade contracts on the outcome of events such as elections or sporting events. Jason Trost, the CEO of Smarkets, sees little difference between the two models and draws a vivid comparison. He emphasizes that it is essentially the same concept operating under different names.

"They’re called betting exchanges in the UK. They’ve existed for 20 plus years in the UK in a very legal, stable framework here. This concept of a prediction market coming to the UK – it’s here already. It’s like soccer and football – they’re not apples and oranges, they’re both apples." - Jason Trost, Chief Executive Officer of Smarkets

Numbers and facts

The Gambling Commission report reveals the hard facts. Between April 2025 and March 2026, the GGY of betting exchanges was just £92.66 million. This represents a market share of only 3.79 percent. For comparison, in the 2016/2017 financial year, this figure stood at a robust £171.53 million. Thus, yield has almost halved within a few years. Particularly bitter is the comparison with traditional high street betting shops. Although these suffer from the general trend toward digitalization, their revenue fell by only 26.8 percent during the same period, while betting exchanges contracted by 46 percent.

While exchanges falter, traditional online bookmakers are moving from strength to strength. Their GGY rose from £1.75 billion to around £2.5 billion. Experts suspect that exchange customers are migrating to traditional sportsbooks. These companies have invested heavily in their products and now offer features such as bet builders or complex multi-sport accumulators, which are often technically harder to implement on a pure exchange platform. Furthermore, platforms in the US like Kalshi and Polymarket are attracting trading volumes that reached an estimated $44 billion last year.

Background

The difference between a betting exchange and a prediction market is more regulatory than functional. On a betting exchange, users bet against each other, and the operator collects a commission. In prediction markets, financial derivatives are traded in the form of event contracts, usually priced between $0 and $1. When an event occurs, the contract is settled at a fixed value, such as $1. In the UK, these products have so far been largely inaccessible to retail customers due to strict rules for binary options, unless they operate under the gambling licenses of betting exchanges.

Nevertheless, there are interesting movements: the IG Group recently acquired the US platform Underdog, and Matchbook became the first British provider to launch its own prediction market section in December. However, the legal situation remains complicated. The UK's Financial Conduct Authority (FCA) is currently investigating whether restrictions on such products could be relaxed. This could pave the way for the US trend to officially reach Europe and breathe new life into struggling exchanges.

Why it matters for German players

For German customers, the situation is even more restrictive. Since the State Treaty on Gambling 2021 (GlüStV 2021) came into force, betting exchanges have effectively no presence in the legal market. The strict requirements of the Joint Gambling Authority of the States (GGL) and taxation make the betting exchange model, where the operator takes only a small commission, economically unviable. Players must therefore focus on providers on the official GGL whitelist. Harsh player protection rules apply there, such as the €1,000 monthly deposit limit via the LUGAS system and the €1 stake limit per spin for virtual slot machines. Prediction markets, as they exist in the US, have not yet been classified as sports betting in Germany but rather as speculative financial products, meaning they do not fall under GGL supervision, which complicates access for casual players.

What it means for GGL-licensed casinos

Casinos and betting providers with a German license benefit indirectly from the weakness of betting exchanges. Since peer-to-peer models are difficult to represent regulatorily in Germany, liquidity is concentrated among licensed bookmakers. For operators, this means they must strengthen their products through innovations like bet builders to retain customers who might otherwise migrate to the unregulated gray market or crypto prediction markets. The GGL strictly ensures that no bets are offered on social events or political elections, which form the core of the prediction market boom in the US. Those who want to play safely should therefore exclusively use platforms that carry the official GGL seal of approval and thus offer legal certainty.
