About Spin Party

Jesper Kampmann Madsen, the founder of London-based tech firm Trace2Trace, is building technology to map the networks behind illegal gambling. Madsen, 35, and born in Denmark, knows what it means to be on the other side of the screen: as his decision to fight illegal gambling stems back to his own addiction, he tells iGB.

He was a teenager when he started gambling habitually. For several years, it remained entertainment. Then, when he was in his early twenties, came a large win on a foreign unlicensed gambling site: around €22,000.

“I remember gambling all of it back the same day because they couldn’t pay it out in full immediately,” he says.

“Prediction markets represent a meaningful second channel for NFL wagering but still small on a relative scale, reflecting a new sector with less of an installed base,” observes EKG.

It’s widely believed that all-or-nothing exchanges are carving out significant niches in states, such as California and Texas, where sports betting is prohibited, but there’s also emerging consensus that the prediction market threat to sportsbooks is easing.

A major advantage for traditional sportsbook operators is their ability to aggressively fund customer acquisition and retention bonuses. As EKG points out, prediction markets have “less ability to be generous with bonuses” because users trade against one another rather than against the house.

According to Çiftçi, the rapid growth of digital payments and cryptocurrencies has transformed illegal betting into a major conduit for money laundering. 

“Casinos, junkets, cryptocurrencies and underground banking are the most critical parts of the money laundering infrastructure that fuels international organised crime,” he said at the time. “The global gambling market will reach $205 billion in 2030.”

The government blocked 548,420 illegal betting and gambling websites between 2006 and 2025, including 84,000 in 2025 alone.
