About Dark Spiral

The timing is significant. The illegal gambling market is attracting growing attention from regulators and the wider industry, while estimates of its size vary considerably depending on definitions and methodology.

A recent Fincord Intelligence report highlighted by the Betting and Gaming Council estimated that illegal online gambling generated around $50 billion in gross revenue globally in 2025. It estimated that around 5,000 operator structures were using more than 15,000 websites and apps.

Other estimates are considerably higher, illustrating how difficult the market is to measure. As an example, separate research from Gaming Compliance International put the value of unregulated online gambling at $5.9 trillion in wagering value in 2025, while estimating that unregulated operators accounted for 78% of global online gaming GGR.

As has been widely documented, sports event contracts are currently the lifeblood of the prediction market industry, but Bernstein notes that won’t be the case on a permanent basis. In fact, the research firm estimates that sports derivatives’ share of industry volume will decline to 35% in 2035, indicating that the aforementioned volume increase will be led by other categories.

The research firm estimates that by 2035, financial derivatives, including event contracts linked to commodities, cryptocurrencies and stocks, will account for 49% of turnover on yes/no exchanges, topping sports to become the largest volume driver. The research firm sees event contracts tied to key performance indicators (KPIs) leading the charge.

“We expect new products such as KPI markets, which allow users to trade a single corporate metric, such as production, deliveries, or subscriber growth, rather than the stock price itself,” observe the analysts. “Further, perp futures are expanding from crypto to commodities and single stock perps.”

In the second quarter of 2026, Flutter’s US revenue fell 6% to $1.683 billion, while sportsbook revenue fell 15%. US adjusted EBITDA fell sharply, and Flutter subsequently reduced its guidance. Despite this, FanDuel retained the number-one US sportsbook position, with Flutter reporting a 39% share of US sportsbook gross gaming revenue.

Ben Robinson, managing partner at Corfai, argues that the American listing achieved what it was supposed to achieve. The problems came afterwards. “The question was which arm of the K-shaped market Flutter would end up on. We have the answer now. Capital is concentrated in a narrow band of technology names and everything else is being marked on earnings.”

A US listing can improve access to capital without making the underlying business more attractive. London has a capital-markets problem. Gambling has an investment problem. The two overlap, but they are not the same thing.
