Elon Musk is in talks with the U.S. Securities and Exchange Commission (SEC) to settle issues related to his disclosure of shares in Twitter, now rebranded as X. The negotiations aim to resolve the matter ahead of a potential SpaceX IPO, which could be the largest in history. Musk disclosed his stake in X 21 days after surpassing the 5% ownership threshold, violating the 10-day disclosure requirement. Additionally, he filed a "Form 13G" instead of the required "Form 13D" for activist investors. Musk's legal team has indicated that some settlement discussions have occurred without the direct involvement of the SEC attorneys managing the case. Resolving this issue is seen as crucial by SpaceX's bankers to clear the path for the anticipated IPO.
