The increasing number of financial fraud cases is expected to drive the growth of the audit and assurance services market going forward. Financial frauds refer to deliberate acts of deception conducted for financial benefit, often involving the misrepresentation, manipulation, or concealment of financial information. Financial fraud incidents are increasing due to the growing digitization of financial systems, which creates greater cyber vulnerabilities and provides fraudsters with more opportunities to exploit inadequate security measures and gain access to significant amounts of sensitive data. The rise in financial frauds is increasing the demand for audit and assurance services, as organizations rely on auditors to independently evaluate financial statements, detect irregularities, and strengthen internal controls to identify and prevent fraudulent activities. For instance, in October 2025, according to the Central Bank of Ireland, an Ireland-based national central bank, Irish resident Payment Service Providers (PSPs) reported $173 million (€160 million) in fraudulent transactions in 2024, representing a 24.5% increase compared to $139 million (€129 million) reported in 2023. Therefore, the increasing number of financial fraud cases is driving the growth of the audit and assurance services market.

Major companies operating in the audit and assurance services market are focusing on developing advanced solutions, such as AI-enabled agentic audit platforms, to proactively identify risks, issues, and control deficiencies. AI-enabled agentic audit platforms are intelligent systems that leverage autonomous AI agents to continuously execute, monitor, and enhance audit processes by analyzing large volumes of data, detecting risks, and assisting compliance decisions with limited human intervention. For instance, in May 2026, Grant Thornton LLP, a US-based audit and assurance firm, launched gtap, an AI-enabled agentic audit platform. The platform was developed as a foundational technology solution to serve as the intelligent core of its audit delivery operations. It integrates analytics, automation, and artificial intelligence across all stages of the audit lifecycle while utilizing a cloud-based, self-service infrastructure to standardize data collection, processing, and analysis. The platform supports data from various ERP systems and replaces fragmented legacy solutions with a unified and secure environment that enables comprehensive analysis and scalable, audit-ready results. It also enables AI-driven workflows and intelligent agents to identify risks, anomalies, and insights in real time, while auditors maintain oversight to ensure audit quality and reliability.
