Tipper-tippee liability and the personal benefit test are the tools federal courts use to decide whether a corporate insider who leaked confidential information, and the person who traded on it, can be punished for insider trading. The rule, in one sentence: the tipper is only liable if they personally benefited from the disclosure, and the tippee is only liable if they knew the information came from an insider who breached a duty for that benefit. Everything else is argument over what counts as a benefit, what the tippee knew, and how far down the chain of gossip the liability can travel.
How Tipper-Tippee Liability Works
Insider trading enforcement is built on Section 10(b) of the Securities Exchange Act of 1934 and the SEC’s Rule 10b-5, which together prohibit any deceptive device in connection with buying or selling securities.1Office of the Law Revision Counsel. 15 USC 78j – Manipulative and Deceptive Devices2eCFR. 17 CFR 240.10b-5 – Employment of Manipulative and Deceptive Devices Neither provision uses the words “insider trading.” Courts filled in the doctrine case by case, which is why the rules governing tippers and tippees read less like a statute and more like a stack of Supreme Court opinions.
Under the classical theory, a corporate insider owes a fiduciary duty to the company and its shareholders. When the insider passes material nonpublic information to an outsider who trades on it, the law treats the trade as if the insider had made it. The insider is the tipper. The person who received the information and traded is the tippee.
The tippee’s liability is derivative. A tippee owes the company no independent duty. Instead, the insider’s duty passes to the tippee at the moment of disclosure, but only when the insider breached that duty in the first place. That is the whole point of the personal benefit test: not every disclosure by an insider is a breach, and if there is no breach, nothing passes to the tippee and no one is liable for trading on the tip.
What Counts as a Personal Benefit
The Supreme Court established the personal benefit test in Dirks v. SEC in 1983. Securities analyst Raymond Dirks received information from a corporate insider exposing a massive fraud at Equity Funding of America and shared it with clients who sold their shares. The SEC censured him. The Court reversed, holding that the insider had not breached any duty because he received no personal benefit from the disclosure.3Justia U.S. Supreme Court Center. Dirks v SEC, 463 US 646 (1983) The test asks a single question: did the insider personally benefit, directly or indirectly, from the disclosure? If not, there was no breach. And without a breach, the tippee inherits nothing.
The obvious benefit is cash. Courts have also found the test satisfied when the tipper got a reduction in personal debt, a promise of future employment, or reciprocal access to someone else’s confidential information. Share of trading profits counts. So does a kickback.
The harder question for decades was whether intangible benefits qualify, and in 2016 the Supreme Court answered it in Salman v. United States. Bassam Salman’s brother-in-law, a Citigroup banker, shared deal information with his brother, who passed it to Salman. The government offered no evidence of money changing hands between the banker and his brother. The Court held that was not required: when an insider makes a gift of confidential information to a close relative or friend, the personal benefit test is automatically satisfied.4Justia U.S. Supreme Court Center. Salman v United States, 580 US 39 (2016) Gifting a tip to a relative who then trades on it, the Court reasoned, is the same as trading yourself and handing the relative the profits.
Salman rejected a narrower reading the Second Circuit had suggested in Newman, which required something of “pecuniary or similarly valuable nature” in return for a family gift. Under current law, the close relationship itself is enough.
Where the test gets murky is the middle ground. Dirks suggested a reputational boost or an expectation of reciprocity could qualify, but courts still disagree on how much reputational benefit is enough and how to separate a status-driven tip from a careless remark. An insider dropping confidential details at a dinner party to impress acquaintances sits in a zone the case law has not fully resolved.
What the Tippee Must Have Known
A tippee is not strictly liable just because they traded on good information. The government has to prove the tippee had the right mental state, called scienter: the tippee knew, or had reason to know, that the information came from an insider who breached a fiduciary duty for personal gain.
The Second Circuit tightened this in United States v. Newman (2014). The defendants were portfolio managers several steps removed from the original insiders, and the court found no evidence they knew who leaked the information, let alone what the insiders got out of it. The convictions were overturned.
When Salman reached the Supreme Court, the government asked the justices to reject Newman‘s knowledge requirement. The Court declined, noting that Salman’s case “does not implicate those issues” because he knew the source and the family relationship.5Supreme Court of the United States. Salman v United States, 15-628 (2016) Newman‘s heightened knowledge standard still governs in the Second Circuit and influences courts elsewhere, with no Supreme Court decision endorsing or overruling it.
Willful blindness closes one escape route. A tippee who receives suspiciously specific information and consciously avoids asking where it came from cannot shield themselves by claiming ignorance. The line between an innocent recipient and a willfully blind one is often where insider trading prosecutions are decided.
The Problem of Remote Tippees
Information rarely stops with the first person who hears it. An insider tells a friend, the friend tells a colleague, the colleague tells a trader. By the time anyone acts on the tip, three or four people may sit between the trader and the original source.
Each link in the chain has to satisfy the same requirements. The original tipper must have received a personal benefit, and the remote tippee must have known or had reason to know of both the breach and the benefit. The further removed a trader is from the source, the harder it is for prosecutors to prove knowledge. Someone who got a tip from a casual acquaintance has a plausible argument that they had no idea the information originated with a corporate insider at all.
Salman left several questions open. The Court did not define how broadly “friend” reaches, how much knowledge a tippee three or four steps removed must have, or whether constructive knowledge alone can support a criminal conviction at that distance. Enforcement against remote tippees stays fact-intensive, and outcomes turn on what the trader knew and when.
When the Tipper’s Duty Runs to Someone Other Than the Company
The classical theory only reaches people who owe a duty to the company whose stock is being traded. The Supreme Court closed a gap in 1997 with United States v. O’Hagan, holding that a person who trades on confidential information obtained through a breach of duty to the source of the information, rather than the issuer, also commits fraud under Section 10(b).6Library of Congress. United States v O’Hagan, 521 US 642 (1997) O’Hagan was a lawyer whose firm advised a company on a tender offer; he bought stock in the target before the deal went public. He owed no duty to the target, but he owed one to his firm and its client, and the Court compared his conduct to embezzlement.
For tipper-tippee analysis, the misappropriation theory expands who can serve as a tipper. An insider at Company A who leaks information for someone to trade Company B’s stock can create liability if the insider misappropriated the information from any source to which they owed a duty. The personal benefit test still applies; the misappropriation theory simply widens the pool of people whose breach can start the chain.
Penalties
Insider trading carries both criminal and civil exposure, and the government often pursues both against the same defendant.
Willful violations of the Securities Exchange Act expose individuals to a maximum fine of $5 million and up to 20 years in prison. For entities, the fine ceiling is $25 million.7GovInfo. 15 USC 78ff – Penalties Criminal prosecution requires proof beyond a reasonable doubt that the defendant acted willfully.
The SEC can pursue civil enforcement on a lower burden of proof. Under 15 U.S.C. § 78u-1, a court can order a civil penalty of up to three times the profit gained or loss avoided from the illegal trading.8Office of the Law Revision Counsel. 15 USC 78u-1 – Civil Penalties for Insider Trading Disgorgement, which forces the violator to return their ill-gotten gains, is a separate remedy.
Supervisors and employers can also face liability. A controlling person who knew or recklessly disregarded the likelihood of insider trading and failed to prevent it faces a separate civil penalty of up to the greater of $1 million or three times the controlled person’s profit, and the same provision reaches firms that knowingly fail to establish or enforce policies designed to prevent insider trading.8Office of the Law Revision Counsel. 15 USC 78u-1 – Civil Penalties for Insider Trading
