State, local and education agencies face growing administrative, regulatory and fiscal demands with greater responsibility but less federal financial support. Changes in federal priorities, softer state revenues, infrastructure needs and rising operational complexity are increasing demand for external expertise. Because government personnel spending is not keeping pace with total purchasing, agencies are relying more heavily on contractors to provide operational capacity, manage compliance and reduce implementation risk.

Buyers increasingly need partners that can connect strategy and program design with implementation, governance, data and performance management. Technology modernization also requires process redesign, workforce adoption and responsible artificial intelligence practices. Professional services firms that can combine specialized expertise with practical implementation support and measurable results will be best positioned to capture a growing share of this expanding market.

Key Findings

• The professional services (PS) market will see steady growth. Spending is forecasted to grow at a compound annual growth rate (CAGR) of 6.8% over the entire 2024–2029 forecast period.
• Financial services and management consulting are the two largest segments. Together they represent two-thirds of total spending, and they sit at the intersection of government modernization and fiscal reform.  
• State governments and cities lead. State governments are by far the largest PS buyer group at $68.2 billion in 2026, and cities as a whole will spend $36.6 billion.
• General government services represent the largest vertical opportunity. This vertical is expected to purchase $53.8 billion in 2026 as governments are looking for practical ways to modernize technology, redesign regulation, and improve performance across departments.
• Contractors are becoming an extension of agency capacity. Short-staffed agencies need external partners that can execute complex work, manage deployment risk and add capacity.
• Federal policy changes and fiscal pressure are increasing demand for advisory services. Reduced discretionary grants, new cost-sharing requirements and softer state revenues are creating demand for various types of financial consulting.
