This article explores the phenomenon of co-opetition – simultaneous cooperation and competition – within the insurance brokerage sector, with a particular focus on the Polish market. While co-opetition has been widely studied among insurers, especially in the context of coinsurance and consortia, its application among intermediaries such as insurance brokers remains underexplored. The study examines the legal and practical dimensions of broker collaboration in Poland, where no specific legislation governs such cooperation. Drawing on empirical data from surveys conducted prior to the annual Congress of Insurance Brokers, the article identifies key motivations for and barriers to co-opetition. Findings suggest that collaboration is often client-driven, influenced by risk complexity, specialized needs, and international engagements. Despite the absence of a formal legal framework, co-opetition among brokers is prevalent and evolving, shaped by market practices and general civil law principles. The study highlights the need for updated regulations to support effective and fair collaboration, suggesting that co-opetition is a natural and beneficial strategy in a competitive yet specialized intermediary market.
