Warren’s Senate Power Play: Subpoenas, Scrutiny and the Crypto Chill

Elizabeth Warren is poised to become chair of the Senate Banking Committee in January, giving the crypto industry’s most vocal congressional critic subpoena power and a direct role in shaping the sector’s regulatory future. Her chairmanship is not yet official, but Democrats won control of the Senate in the November 3 midterms, and as the panel’s ranking Democrat she is expected to secure the position.

Warren’s agenda could target specific companies and tokens through committee investigations, hearings and subpoenas. The Wall Street Journal reported that insider trading on prediction markets, consumer protection at crypto companies and alleged conflicts of interest involving Donald Trump and his family are among her early priorities. On October 28, Warren and Republican Sen. John Curtis asked Kalshi and Polymarket how they prevent insider trading on election bets. She has also criticized the Office of the Comptroller of the Currency for allowing nine crypto firms to operate like banks, including Coinbase, and in May asked the SEC to examine whether World Liberty Financial (WLFI), the Trump family’s crypto company, misled investors.

Her greatest immediate influence could come through legislation. The CLARITY Act, which would establish clear rules for crypto oversight, failed a key Senate vote 49-50 on September 15. Warren opposed the bill, saying, “Donald Trump raked in more than $1.4 billion from cryptocurrency ventures, and this bill does nothing to prevent him from vacuuming up his next $1.4 billion in crypto profits. The underlying bill still fails to adequately protect investors, our financial system and our national security. This bill should be dead on arrival.” Any revised measure would need to clear the Senate Banking Committee before advancing.

Public hearings and compulsory testimony could create headline risk for companies and tokens linked to Warren’s investigations. WLFI trades near $0.047, close to the record low it set on November 5, according to WLFI price data from BeInCrypto, and is down about 61% in a year. Warren will also oversee nominations for regulators including the SEC, with Democrats’ new Senate majority able to block Trump’s nominees. Warren cannot write rules alone, and her authority over legislation, hearings and appointments will remain constrained by the broader congressional process.
