How to play Double Rainbow

Helios, a specialist consultant in gambling web traffic, analysed the number of black market websites actively marketing across the 28 markets included in the report, between March and May.

This data was cross referenced with SimilarWeb traffic analysis to confirm the scale of activity. In some markets, the number of illegal sites being actively marketed was much higher than those that have local licences to operate.

This was true of France, Portugal, Netherlands, Germany, Cyprus, Belgium, Spain, among others.

About Double Rainbow

Misleading messages: Messages that present betting as a risk-free activity, a source of income, a financial solution, a sure profit, a guaranteed method or a way to recover losses cannot be disseminated.

The restriction does not extend to strictly institutional communication made through the authorised operator’s own official channels, such as websites, apps, internal platform areas and customer service channels. In these spaces, information should be limited to company identification, official channels, access rules, self-exclusion and blocking mechanisms and mandatory warnings.

These channels may not contain promises of winnings, bonuses, invitations to bet, boosting or features designed to attract and retain user attention. The operator will also be responsible for the actions of affiliates, agencies, influencers, and other third parties who are paid or incentivised for commercial promotion.

If Bernstein’s $10 trillion prediction market turnover forecast is realized or exceeded, it’d likely prove significant in revenue terms because the research firm previously estimated that $1 trillion in yearly activity could generate as much as $10.8 billion in revenue for operators.

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.
