[CoinDesk] Warren: What is White House doing to prevent a repeat of teleprompter's Trump bets?

Senator Elizabeth Warren pressed the White House over whether it is doing enough to prevent a repeat of the insider-trading controversy tied to Trump-linked prediction-market bets placed through the CFTC-regulated platform Kalshi. Warren questioned whether the Commodity Futures Trading Commission's enforcement response to the episode was adequate, arguing that administration staff trading on prediction markets may require stronger guardrails than a one-off penalty. The dispute matters because prediction markets such as Kalshi and Polymarket are increasingly treated as real-money venues for pricing political and economic events, putting federal ethics and market-integrity rules under fresh scrutiny. What to watch next is whether Warren's pressure yields formal CFTC rulemaking or congressional hearings on insider trading in event contracts, and whether the White House issues its own staff trading guidance.
