Aug 10 (Reuters) - Prediction markets giant Kalshi has joined hands with Nasdaq to adopt the U.S. exchange heavyweight's market surveillance tool, as ‌it looks to bolster the monitoring and oversight of trading activity ‌on its platform. Kalshi plans to implement Nasdaq's market surveillance platform in a phased approach, pairing its existing surveillance framework ‌with advanced monitoring capabilities for ⁠prediction markets and perpetual-style derivatives. A White House teleprompter operator is also under investigation over potential insider trading on Kalshi, Reuters reported. Kalshi, which has also ramped up ‌hiring in its surveillance unit this year, ​had referred suspicious trading activity in both cases ​to regulators. Nasdaq's market surveillance platform serves over ‌50 exchanges and 20 international regulators ​globally, helping detect ​potentially abusive trading behaviors across asset classes.
