Siebert Financial Corp said the U.S. Securities and Exchange Commission has declared effective its S-3 shelf registration statement, allowing the Nasdaq-listed brokerage to raise as much as $100 million. The company intends to use the proceeds to buy digital assets—including Bitcoin, Ethereum and Solana—fund artificial-intelligence initiatives and pursue strategic acquisitions. The registration permits Siebert to issue a variety of securities, giving the firm flexibility to tap capital markets as investment opportunities arise. Separately, National Securities Depository Ltd. is moving ahead with an initial public offering that could raise about $400 million as early as July 2025, according to multiple reports. India’s central securities depository secured regulatory clearance from the Securities and Exchange Board of India in October 2023 and is now finalizing details of the share sale.
