Definition
A fraudulent or grossly speculative commercial scheme promoted through a fictitious or exaggerated prospectus to attract investment from the public. The term describes both the scheme itself and the corporate vehicle created to carry it out. Companies organized for such purposes — typically offering little of substance while promising outsized returns — are called bubble companies.
The term derives its force from the South Sea Bubble of 1720, one of the most consequential financial collapses in English history, which led directly to the Bubble Act of 1720 (6 Geo. I, c. 18). That statute restricted the formation of joint-stock companies without royal charter and remained English law for over a century, until its repeal in 1825. The legal meaning of "bubble" is therefore tightly bound to this legislative history.

Common Language
Modern common usage (Wiktionary): To produce bubbles; to rise up in bubbles; also, informally, to cheat or delude someone.
Historical common usage (Webster's 1913): A thin film of liquid inflated with air or gas; also a globule of air or vacuum within a solid — the core image being something that appears larger than it is and will inevitably collapse.
The common meaning supplies a useful image but not the legal content. In law, "bubble" is not merely metaphorical. It describes a recognized category of fraudulent commercial enterprise. The Wiktionary sense of "to delude or hoodwink" comes closest to the legal use, but the legal term carries specific historical weight — tied to regulatory responses, statutory prohibitions, and corporate law development — that the ordinary word does not.

Why It Matters in Research
Researchers will encounter "bubble" primarily in three contexts: English equity and fraud cases from the eighteenth and nineteenth centuries; commentary on the Bubble Act and its repeal; and comparative corporate law scholarship examining the origins of restrictions on joint-stock companies.
The term is flagged by both editions of Black's as being "chiefly used in England." This is important. American legal sources largely absorbed the concept under broader fraud, securities, or corporate law frameworks without adopting the term as a technical category. A researcher searching American reporters for "bubble" as a legal term of art will find sparse returns. The action — fraudulent promotion of speculative schemes — exists in American law but travels under different labels.
The Bubble Act's long shadow affects how English equity courts discussed corporate formation and promoter liability well into the nineteenth century. Researchers working in that period should understand that "bubble company" in source texts is not generic skepticism about a risky venture — it is a specific accusation of fraudulent or ultra vires organization.
In modern usage, "bubble" has returned to prominence in financial and regulatory commentary — asset price bubbles, housing bubbles — but this is economic usage, not a legal term of art. Do not read modern financial uses back into historical legal texts, and do not treat historical legal uses as anticipating modern macroeconomic concepts.

Historical Dictionary Support
Both editions of Black's are in close agreement, differing only in a minor spelling correction ("ficticious" corrected to "fictitious" in the second edition) and a small punctuation difference. Neither edition elaborates significantly beyond the base definition. Both note that the term is "chiefly used in England," which is accurate but potentially understates the term's legal significance: the Bubble Act shaped English and colonial corporate law for over a century, and its repeal in 1825 was itself a watershed moment in corporate law history.
Neither edition of Black's cites the Bubble Act by name or situates the term within the broader regulatory history — a gap that modern researchers should fill with secondary sources. The definition treats "bubble" as descriptive rather than as a term with precise legal operation, which is appropriate: it was never a term of formal legal art in the way that, say, "consideration" or "indictment" are, but rather a recognized category in fraud and corporate law discourse.

Jurisdictional Note
The term carries technical legal weight primarily in English law, where the Bubble Act (1720) gave it statutory context. American law absorbed analogous concerns through general fraud doctrine, promoter liability principles, and, eventually, securities regulation, without adopting "bubble" as a distinct legal category. Researchers working in pre-twentieth-century English sources will encounter the term with legal precision; in American sources, it appears mainly in commentary and historical discussion.
