the U.S. Securities and Exchange Commission (SEC) is preparing to introduce a new policy that would allow crypto companies to offer blockchain-based tokenized stock trading, potentially having a significant impact on the traditional stock market structure. According to SEC Chairman Paul Atkins, companies will be permitted to experiment with new digital asset business models, including the tokenization of US stocks, without fully complying with existing disclosure and investor protection rules.However, the proposal has also raised concerns among traditional financial institutions such as Citadel Securities and SIFMA, who argue that such changes could divert liquidity and create regulatory arbitrage risks. As of now, the SEC has not made any public comments on the matter. (Reuters)

According to The Block, Jim Esposito, President of Citadel Securities, stated on Thursday at the Semafor World Economic Forum in Washington, D.C., that the firm is “fully capable” of providing liquidity to prediction markets—but explicitly expressed no interest in sports-event contracts. Instead, he emphasized the value of prediction markets for hedging geopolitical risks, citing the U.S. midterm elections this November as “one of the greatest risks facing investors’ portfolios.” Esposito noted that as platforms like Kalshi and Polymarket continue to grow rapidly, the prediction market is poised for sustained expansion—naturally drawing Citadel Securities into the space. Notably, Zhao Peng, CEO of Citadel Securities, participated last year in Kalshi’s $185 million funding round.
