According to CNBC, citing a committee aide on Warren's team, Elizabeth Warren is poised to take the helm of the Senate Banking Committee. The aide stated that her priorities for the new Congress convening in January include lowering the cost of living, tightening export controls on advanced AI chips to China, and formulating regulatory rules for prediction markets, though the official agenda has not yet been released. Warren and Republican Senator John Curtis have sent letters to Kalshi and Polymarket requesting information on safeguards for election-related markets; she has also asked relevant figures in the technology, government, and financial sectors to preserve documents in preparation for the proposed oversight efforts.
