A market definition in competition law identifies the boundaries of the competitive space within which a company operates — both the product market (which products compete with each other) and the geographic market (the area within which competition takes place). Market definitions are the foundation of merger control analysis; without establishing what market a transaction affects, it is difficult to assess competitive effects.
In merger control, competition authorities use market definitions to determine the perimeter within which to assess whether a proposed transaction will harm competition. The outcome of a market definition analysis can be decisive for whether a merger is cleared, blocked, or subject to remedies.
The SSNIP test (Small but Significant Non-transitory Increase in Price) is a standard methodology for market definition used by the European Commission, Bundeskartellamt, CMA, and most other European authorities. It asks what would happen if a hypothetical monopolist imposed a small but significant (typically 5-10%) non-transitory price increase. If buyers would switch in sufficient numbers to make the increase unprofitable, those alternatives belong in the same market.
CuriAI currently indexes market definitions from the European Commission (DG COMP), the German Bundeskartellamt (BKartA), the UK Competition and Markets Authority (CMA), the French Autorite de la concurrence (ADLC), the Turkish Rekabet Kurumu (TCA), the Swedish Konkurrensverket (KKV), the Spanish CNMC, the Belgian Competition Authority (BCA), the Irish CCPC, the Dutch ACM, and the Nordic authorities of Norway, Finland, and Denmark. Coverage is available in English regardless of the original decision language.
CuriAI uses AI to index, analyse, and synthesise market definition content from competition authority decisions across multiple languages. Lawyers can search in English and receive AI-generated summaries with direct citations to source paragraphs — even when the underlying decision was published in German, French, Swedish, Turkish, Spanish, Dutch, or another language.
Competition authorities are generally not bound by precedents from other authorities, but cross-border citations are common and accepted practice. Decisions from the European Commission are particularly influential across EU member states and globally. National authority decisions — especially from large jurisdictions like Germany, France, and the UK — are regularly cited in filings before other authorities when market structures are comparable.
