frontrunning
C1Formal/Technical
Definition
Meaning
A type of financial market manipulation where a broker or trader exploits advance knowledge of a large pending client order to place their own trade first, thereby profiting from the subsequent price movement.
More broadly, any unethical practice of using privileged, non-public information to secure an advantage, especially by acting before others with a right to that information. Can occur in contexts beyond finance (e.g., politics, sports, technology).
Linguistics
Semantic Notes
The term is predominantly negative, implying illegality or unethical behaviour. As a financial term, it is distinct from legitimate high-frequency trading based on public data, though the line can be blurry in practice.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'передний бег'. The closest conceptual equivalent is 'торговля на опережение (с использованием инсайда)' or the borrowed 'франтраннинг'. 'Инсайдерская торговля' (insider trading) is a related but distinct legal concept.
Common Mistakes
- Using 'frontrunning' to describe legitimate, fast reaction to public news (incorrect). Confusing it with 'high-frequency trading' (HFT is a method, frontrunning is an abuse). Spelling as 'front running' (often spelled as one word in financial contexts).

Frequently Asked Questions
