A predicate act is an underlying criminal offense that counts toward a larger federal charge, most often under the Racketeer Influenced and Corrupt Organizations Act (RICO) or the federal money laundering statutes. Standing alone, a predicate act is already a crime with its own penalties. Stacked together in a pattern of two or more, predicate acts unlock far more severe federal exposure: decades in prison, six- and seven-figure fines, and mandatory forfeiture of assets tied to the conduct. Congress built the concept because dismantling organized criminal activity requires prosecuting the pattern, not just the isolated incidents inside it.
The statutory list of qualifying crimes appears in 18 U.S.C. § 1961, which defines “racketeering activity” for RICO purposes.1Office of the Law Revision Counsel. 18 USC 1961 – Definitions To win a RICO conviction, the government must prove beyond a reasonable doubt that the defendant committed at least two of these qualifying acts as part of a pattern of racketeering activity.2United States Department of Justice. Criminal Resource Manual 109 – RICO Charges Prior convictions for those offenses are not required. The prosecution only has to show the acts were “chargeable” under state law or “punishable” under federal law.
Which Crimes Count as Predicate Acts
The list is deliberately broad, capturing the range of conduct organized criminal enterprises typically engage in, from street violence to sophisticated financial fraud. It splits into two categories.
The first covers state-law offenses punishable by more than a year in prison: murder, kidnapping, robbery, arson, bribery, extortion, gambling, and drug trafficking.1Office of the Law Revision Counsel. 18 USC 1961 – Definitions These are the crimes historically associated with organized crime families, and they remain among the most commonly charged predicates.
The second is an extensive list of federal offenses:
- Mail and wire fraud (using the postal system, phone lines, or the internet to carry out a scheme to defraud)
- Bribery and extortion, including corrupt payments to officials
- Financial fraud, including embezzlement from union funds, bankruptcy fraud, and securities fraud
- Drug offenses involving manufacturing, importing, or distributing controlled substances
- Immigration offenses involving smuggling or harboring people for financial gain
- Counterfeiting and identity fraud
- Terrorism offenses listed in 18 U.S.C. § 2332b
The statute also reaches offenses under the Currency and Foreign Transactions Reporting Act, including structuring transactions to evade bank reporting requirements. One common misconception: the list references embezzlement from union funds under Title 29, not pension funds generally.
Two Acts Is the Floor, Not the Finish Line
Two predicate acts are necessary but not automatically enough. In H.J. Inc. v. Northwestern Bell Telephone Co. (1989), the Supreme Court held that the acts must also satisfy two tests: relationship and continuity.3Legal Information Institute. H.J. Inc. v. Northwestern Bell Telephone Co.
The relationship test asks whether the acts share common purposes, results, participants, victims, or methods. Two unrelated crimes committed years apart by the same person typically don’t form a pattern. Prosecutors have to show a thread tying the acts to each other and to the enterprise.
The continuity test asks whether the criminal activity extended over time or threatened to continue. Courts recognize two forms. Closed-ended continuity means the conduct actually lasted a substantial period, generally well beyond a few months. Open-ended continuity exists when the nature of the activity itself implies a threat of repetition, such as when the predicate acts are the regular way a group operates.3Legal Information Institute. H.J. Inc. v. Northwestern Bell Telephone Co. A short-lived scheme that ran for a few weeks, even one involving several crimes, will struggle to clear this bar.
Both tests must be met. Sporadic, unrelated crimes don’t form a pattern no matter how many there are, and tightly related acts confined to a brief window may fail continuity.
There is also a time frame written into the statute. The predicate acts must have occurred within ten years of each other, with any period the defendant spent in prison excluded from that count.1Office of the Law Revision Counsel. 18 USC 1961 – Definitions
The Enterprise Requirement
RICO reaches conduct done through an “enterprise.” That can be a corporation, a partnership, a union, or a loose group of people working together with no formal structure. The statute defines it to include “any union or group of individuals associated in fact although not a legal entity.”1Office of the Law Revision Counsel. 18 USC 1961 – Definitions That elasticity is what makes RICO effective against street gangs, drug networks, and corrupt political operations that have no corporate charter.
The predicate acts have to connect to that enterprise’s affairs. Section 1962 prohibits four kinds of conduct: investing racketeering income in an enterprise, acquiring control of an enterprise through racketeering, conducting an enterprise’s affairs through racketeering, and conspiring to do any of those things.4Office of the Law Revision Counsel. 18 USC 1962 – Prohibited Activities A defendant who committed qualifying crimes on their own, disconnected from any enterprise, has not violated RICO.
Predicate Acts in Money Laundering
Federal money laundering under 18 U.S.C. § 1956 works on the same principle but uses different terminology. Instead of “racketeering activity,” it requires a “specified unlawful activity,” or SUA, as the predicate. The government must prove that money involved in a financial transaction was the proceeds of one of the listed crimes.5Office of the Law Revision Counsel. 18 USC 1956 – Laundering of Monetary Instruments Without tracing the funds back to an identifiable predicate crime, the laundering charge collapses.
The SUA list is broader than the RICO predicate list. It sweeps in everything that qualifies as racketeering activity under § 1961 and adds environmental crimes such as Clean Water Act violations, health care fraud, foreign corruption, Endangered Species Act offenses, and crimes against foreign nations involving drug trafficking, fraud against foreign banks, and public corruption.6Office of the Law Revision Counsel. 18 U.S. Code 1956 – Laundering of Monetary Instruments
The statute also has a knowledge element that separates laundering from simply handling dirty money. The defendant must know the property involved in the transaction represents the proceeds of some form of unlawful activity, though the defendant need not know the specific crime that generated it.
Why the Predicate-Act Label Matters
Once an offense is charged as a predicate act inside a RICO or money laundering count, the exposure changes shape.
A RICO conviction carries up to 20 years in federal prison per count. If the underlying predicate carries a life sentence, such as murder, the RICO count can also result in life imprisonment.7Office of the Law Revision Counsel. 18 U.S. Code 1963 – Criminal Penalties Individual defendants face fines up to $250,000 per count under the general federal sentencing statute, or twice the gross profits from the offense, whichever is greater.8Office of the Law Revision Counsel. 18 USC 3571 – Sentence of Fine
Money laundering convictions carry up to 20 years in prison and fines up to $500,000 or twice the value of the property involved in the transaction, whichever is greater.5Office of the Law Revision Counsel. 18 USC 1956 – Laundering of Monetary Instruments Because that fine is pegged to transaction value rather than a flat cap, it can dwarf the standard federal felony maximum in cases involving large sums.
A RICO conviction also triggers mandatory forfeiture. The government can seize any interest the defendant acquired through the racketeering activity, any property giving the defendant influence over the enterprise, and any proceeds obtained directly or indirectly from the criminal conduct. Real estate, bank accounts, business interests, vehicles, and personal property of any kind are all on the table. The government’s right to the property vests at the moment the criminal act occurs, not at conviction. Property transferred to a third party after the crime remains subject to forfeiture unless the new owner proves they were a good-faith purchaser with no reasonable cause to believe the property was forfeitable.9Office of the Law Revision Counsel. 18 USC 1963 – Criminal Penalties
Predicate Acts Are Not Overt Acts
People sometimes mix up predicate acts with “overt acts,” a term that comes up in conspiracy cases. The distinction matters.
An overt act in a conspiracy charge is any step, however small, taken to advance the conspiracy’s goal. It need not be a crime. Renting a car, making a phone call, or opening a bank account can all qualify. The prosecution typically needs to prove just one overt act by any member of the conspiracy.
A predicate act must be an independently chargeable crime from the specific list in the RICO statute, and it carries real legal weight on its own. Where an overt act shows the conspiracy is operational, predicate acts show the defendant engaged in serious criminal conduct through an enterprise. RICO demands at least two of them forming a pattern, a much higher threshold than a single non-criminal overt act.
How Defendants Fight the Predicate-Act Framing
Defendants facing charges built on predicate acts usually attack the links prosecutors need to connect, rather than each underlying crime one at a time.
- No pattern. Even with two or more predicate acts proven, defendants can argue the acts fail the relationship or continuity tests from H.J. Inc. Crimes committed for different reasons, against unrelated victims, using different methods may not relate. A short burst of activity with no threat of continuation may not show continuity.
- No enterprise connection. If the defendant committed qualifying crimes independently, not through or for the benefit of any enterprise, the RICO theory fails.
- Knocking out individual predicates. Because each predicate act must be provable as a crime in its own right, defeating enough of them can drop the total below two and end the RICO count.
- Statute of limitations. Criminal RICO prosecutions fall under the general five-year federal statute of limitations. Prosecutors generally satisfy this as long as at least one predicate act in the charged pattern occurred within five years of the indictment, so if all of the acts predate that window, the case is time-barred.10Office of the Law Revision Counsel. 18 USC 3282 – Offenses Not Capital
- Lack of knowledge in laundering cases. Showing the defendant did not know the funds were illegally sourced defeats the knowledge element the statute requires.
Judges scrutinize the pattern element carefully. Courts have dismissed RICO indictments where the predicate acts amounted to a single criminal episode rather than an ongoing pattern, even when the individual crimes were serious.
