What Is the Wire Act and What Does It Cover?

The Wire Act is the federal law that makes it a crime for a person engaged in the business of betting or wagering to use a wire communication facility, such as a telephone line or the internet, to send certain bets or betting information across state or international lines. As of October 2026, the leading court decision, from the U.S. Court of Appeals for the First Circuit, reads its prohibitions as limited to sports betting, while a 2018 Justice Department opinion reads most of them as covering any form of wagering. The law’s scope is therefore still contested.

That matters because a 1961 law written for telephones now sits underneath debates over online sportsbooks, online poker, state lotteries and iGaming. This article explains the text, its history, what courts and agencies have said, and what remains unsettled.

Where the Wire Act Comes From

The Wire Act was enacted on September 13, 1961 as Public Law 87-216 and is codified at 18 U.S.C. § 1084, titled Transmission of wagering information; penalties, according to the U.S. Code text published by Cornell’s Legal Information Institute. A 2019 report from the Congressional Research Service describes it as part of an anti-racketeering package from the same era and notes that Congress has left it essentially unchanged since then.

The U.S. Code’s notes list amendments in 1988, 1990 and 1994. Those changes added references to foreign countries, defined the term State, and replaced an older fixed fine of up to $10,000 with a fine set under Title 18. As reviewed in October 2026, the published text shows no amendments after 1994.

The same Congressional Research Service report notes that, before 2011, the Justice Department relied on the Wire Act primarily to prosecute sports-related gambling, with only rare recourse to it for other forms. The key point for modern readers is that the text predates the commercial internet by decades, so courts and the Justice Department have had to apply 1961 language to technology Congress never contemplated.

What the Wire Act Says

Section 1084(a) is a single long sentence with two clauses. It applies to a person “engaged in the business of betting or wagering” who knowingly uses a wire communication facility for particular transmissions in interstate or foreign commerce. In plain English, the target is a betting business, not an individual customer.

The two prohibitions

The first clause covers the transmission of bets or wagers, or information assisting in the placing of bets or wagers, “on any sporting event or contest.” The second clause covers a wire communication that entitles the recipient to receive money or credit as a result of bets or wagers, or information assisting in the placing of bets or wagers. The central dispute is whether the phrase “on any sporting event or contest” limits only the first clause or the whole subsection.

The exceptions and limits

Subsection (b) says the law does not prevent transmitting information for news reporting of sporting events, or transmitting information assisting in the placing of bets on a sporting event from a place where that betting is legal into a place where it is also legal. Subsection (c) states that the section creates no immunity from prosecution under state law, so the federal statute does not shield anyone from a state charge. Subsection (d) concerns common carriers that receive written notice from law enforcement.

The penalty

A violation is punishable by a fine, up to two years in prison, or both. For purposes of the statute, the term State includes the District of Columbia, Puerto Rico and U.S. territories and possessions.

How the Wire Act Is Applied in Practice

Because the statute is criminal, its practical reach has depended on how federal prosecutors read it. Whether a given transmission falls inside the statute depends on the type of wager, who sends it, and where the parties are located, which is why courts parse the text so closely.

A hypothetical shows how the structure works in general terms. Suppose a business takes wagers on professional sporting events by internet from another state. Under the First Circuit’s reading, that is the core of what the first clause addresses, and subsection (b) would matter only for information moving between places where the betting is legal. For a lottery vendor processing ticket sales across state lines, the answer turns on the disputed question of whether non-sports wagering is covered at all.

The stakes extend well beyond sportsbooks. The First Circuit noted in 2021 that 48 states or territories operate lotteries, and that New Hampshire’s lottery alone contributed $87.2 million to the state’s Education Trust Fund in fiscal year 2018. The 2018 Justice Department opinion itself acknowledged that some states began selling lottery tickets online after the 2011 opinion. In response, the department issued forbearance memoranda that it described as an exercise of prosecutorial discretion and not a safe harbor for violations.

What Is Still Disputed: Court Rulings and DOJ Opinions

The scope of the statute has changed hands repeatedly. In 2011, the Justice Department’s Office of Legal Counsel (OLC) concluded that the Wire Act does not reach wire communications unrelated to a sporting event or contest. On November 2, 2018, OLC reversed that view, concluding that the prohibitions are not uniformly limited to sports gambling, with one exception for information assisting sports bets. The Deputy Attorney General adopted it in January 2019 and later extended a forbearance period through December 1, 2020.

The New Hampshire Lottery Commission and its vendor challenged the 2018 opinion. On January 20, 2021, the First Circuit decided New Hampshire Lottery Commission v. Rosen, 986 F.3d 38, holding that the prohibitions of section 1084(a) “apply only to the interstate transmission of wire communications related to any ‘sporting event or contest.’” The court affirmed declaratory relief but vacated the lower court’s order setting aside the 2018 opinion.

On September 15, 2022, a federal district court in Rhode Island entered a declaratory judgment in a separate case, International Game Technology PLC v. Garland, applying the First Circuit’s reading to those plaintiffs. Both rulings are limited in reach: the First Circuit’s holding controls within that circuit, and the declaratory judgments protect the named plaintiffs, which limits their reach. In sources reviewed for this article, no official document shows the 2018 opinion being formally withdrawn as of October 2026.

The table summarizes the key dates as of October 2026, each drawn from the sources listed below.

The table should not be read as a single settled timeline, because rulings and memoranda operate differently. Congress could resolve the question by amending the statute, as the Congressional Research Service noted in 2019, but no such amendment appears in the published Code text as of October 2026.

Common Misconceptions About the Wire Act

Misconception one: the Wire Act bans online gambling. The statute does not use that phrase. It addresses particular wire transmissions by people in the business of betting, and whether an online activity is lawful also depends on other federal statutes and, above all, on the law of the relevant state.

Misconception two: the law targets individual bettors. The text is directed at those “engaged in the business of betting or wagering.” It does not by its terms describe a customer placing a wager.

Misconception three: the First Circuit settled the question for the whole country. The decision is binding precedent only in that circuit, and the Justice Department’s 2018 opinion was not set aside. The First Circuit noted that the Fifth Circuit had earlier read the statute the same way, but courts elsewhere are not bound by either decision.

Misconception four: a state license makes a transmission lawful under federal law. The Wire Act and state licensing are separate systems. Subsection (c) preserves state prosecution, and the statute’s one legality-based carve-out, in subsection (b), is limited to sports-betting information moving between places where that betting is legal. Nothing in the text makes a state license a general defense.

Where to Find the Official Rules

The statute’s text is published in the U.S. Code, the First Circuit’s opinion is on the court’s website, and the Office of Legal Counsel publishes its opinions on the Justice Department’s website. Reading the original text and rulings avoids the shortcuts of secondary summaries.

The Wire Act says nothing about whether a particular form of gambling is lawful in a particular state. That question belongs to state statutes and the state’s gaming regulator, whose websites are the authoritative place to confirm current rules. Anyone with a question about how these laws apply to their own circumstances should consult a licensed attorney in their state.

Related Federal Laws to Understand Next

The Wire Act is best understood alongside the other federal gambling laws it interacts with. The Unlawful Internet Gambling Enforcement Act of 2006, codified at 31 U.S.C. §§ 5361 to 5367, deals with payments connected to unlawful internet gambling, and its own text says it does not alter, limit or extend other federal or state gambling laws. The Justice Department’s 2018 opinion relied on that point to conclude that the 2006 law left the Wire Act’s scope unchanged. Tribal gaming and state-by-state rules are separate topics.
