The use of artificial intelligence (AI) and machine learning (ML) by businesses, including U.S. insurers, has grown considerably over time. While there are clear benefits to using AI, there are also significant concerns, including the potential for unfair discrimination and the protection of consumer information. In this article, we discuss how and to what extent insurers are using AI across multiple lines of business. A summary of the NAIC AI model bulletins and their take-up rates is provided, along with suggested considerations for future AI-related bulletins that could strengthen adherence to the guiding principles. Furthermore, we review existing and proposed state laws as well as current federal laws that directly or indirectly impact the insurance industry’s use of AI. We find that over 70% of automobile, homeowners, and health insurers are currently using, planning to use, or exploring the use of AI, while 58% of life insurers report the use, planned use, or exploration of use. Additionally, though the operational uses of AI varies among insurers, insurers more commonly use AI in marketing and claims. We also observe that 24 states have adopted NAIC AI model bulletins, while five states have issued industry guidance or successfully passed relevant legislation, with key areas of focus including medical professional decision-making authority, mandatory disclosure of AI use, and violation enforcement.
