Swedish prosecutor Jonas Myrdal said a likely information leak may have occurred before Sivers Semiconductors announced its U.S. dual listing. According to his statement, an anonymous X account with roughly 200,000 followers published the claim about 48 hours ahead of the company’s official disclosure, after which the stock rose several hundred percent. He called on Nasdaq to investigate whether the episode involved violations of the EU Market Abuse Regulation, which is designed to prevent insider dealing, unlawful disclosure of inside information, and market manipulation.
