Quick answer
Insider usually means a person who possesses confidential, non‑public information about a company. In contracts, it matters because using that info can void the agreement and bring penalties. Before signing, verify that no insider information is being relied upon.
Definitions
What is insider?
Legal Definition
When a person with confidential, non‑public information about a company uses that knowledge in a transaction, the law calls them an insider. The fiduciary duty to refrain from self‑dealing can trigger rescission, damages, or securities enforcement under 15 U.S.C. § 78j. Courts focus on whether the individual breached a duty of loyalty owed to the entity or its shareholders.
Plain-English Translation
Think of a hall pass that lets a student skip class; an insider’s secret pass lets them trade before others know the news, and they get caught if they use it.

Who is affected?
Corporate officers risk personal liability for breaching the duty; shareholders may seek damages; underwriters must verify that no insider trading occurred before closing.
