What legal precedent was established regarding the liability of the brothers in Salman v. US?

In Salman v. US, the court established that individuals who provide insider information (tippers) can be held liable for insider trading, even if they do not personally share any financial gain with those who receive the information (tippees). This case clarified that the act of tipping itself constitutes a violation, reinforcing the principle that sharing confidential information for trading purposes, regardless of profit-sharing arrangements, is unlawful.

The court underscored the idea that familial relationships, particularly close ones such as between brothers, do not create a safe harbor for insider trading. In this scenario, the relationship between the brothers emphasized the court's stance that the integrity of the securities market is paramount and that close kinship does not lessen the responsibility of a tipper when insider information is shared. Thus, the precedent set firmly holds tippers liable, aligning with regulatory expectations against insider trading practices.
