Polymarket turns to Palantir for sports betting integrity

Polymarket, the world’s largest prediction market, said Tuesday it had formed a partnership with Palantir Technologies to monitor its sports betting markets; a move that comes as the platform faces an intensifying wave of insider trading allegations.

The tie-up will use Vergence AI, a joint venture between Palantir and TWG AI launched last year, to monitor trades in near real-time, screen out prohibited participants and generate automated compliance reports.

Once dismissed as a niche crypto curiosity, prediction markets have burst into the mainstream in just a few years, striking partnerships with major news organisations as real-time forecasting tools, and positioning themselves as an alternative to both traditional polling and licensed sports gambling.

Polymarket allows users to buy and sell shares tied to the probability of real-world events, from election outcomes to military strikes.

But the growth and visibility have brought growing pressure on Polymarket and its archrival Kalshi over suspected abuse of privileged information.

Several accounts reportedly made around $1.2 million in profits on Polymarket after placing bets predicting US military action against Iran hours before the strikes began.

Crypto-analytics firm Bubblemaps identified what it called “six suspected insiders” behind the wagers.

In January, a separate trader reportedly earned over $400,000 after betting that Venezuelan leader Nicolas Maduro would be removed from power, shortly before reports emerged of an operation targeting him.

US Senators Jeff Merkley and Amy Klobuchar have introduced the End Prediction Market Corruption Act, which would bar the president, vice president and members of Congress from trading event contracts on prediction platforms, and impose fines for violations.

Sports markets have drawn separate scrutiny. According to the Wall Street Journal, an anonymous day-old Polymarket account had correctly predicted 17 out of around 20 bets about the Super Bowl halftime show, strongly suggesting the account had some kind of insider knowledge.

Polymarket Founder and CEO Shayne Coplan said the Palantir deal would allow the platform to apply “world-class analytics and monitoring to sports markets” while giving leagues and teams tools to maintain confidence in outcomes.

Drew Cukor, global head of AI at TWG AI, said integrity monitoring could not be treated as an afterthought.

“Market integrity isn’t a feature you bolt on after the fact – it has to be engineered into the foundation of how an exchange operates,” he said.

The US president’s son, Donald Trump Jr., joined Polymarket’s advisory board last year after his venture capital firm, 1789 Capital, invested in the company.

Peter Thiel, a prominent Trump ally, is the co-founder of Palantir and also an investor in Polymarket.
