Devils Diamond Rush

About Devils Diamond Rush

This followed a period of restrategising for the operator, after rebranding from GVC Holdings and committing to having 100% of its revenues come from regulated markets.

But its share price has taken a tumble over the last year, dropping up to 37% since September 2025. Its market cap currently sits at £3.39 billion.

The operator first started trading on LSEG’s main market in February 2016 under its previous company name GVC Holdings. This followed its delisting from the Alternative Investment Market (AIM exchange).

About Devils Diamond Rush

Earlier this year, fellow prediction market platform Polymarket also ended its paid relationship with Santos amid a Department of Justice investigation over whether he had placed a wager on his appearance at the same State of Union address. 

A federal judge sentenced Santos to 87 months in prison last April on felony wire fraud and check fraud charges. After Santos served several months in 2025, US President Donald Trump granted the former congressman clemency, resulting in his immediate release. 

Shortly after his release, Santos had begun working as an influencer for Polymarket.

The $10 trillion forecast also implies significant growth in just five years from what previously stood as some of the most optimistic 2030 projections. In April, Bernstein estimated prediction market volume will ascend to $1 trillion by 2030 while Bank of America said prediction markets will eventually grow to $1.1 trillion in yearly turnover. A July report from Macquarie analyst Chad Beynon included a $1.5 trillion annual volume forecast by 2030.

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.
