The US consulting market is projected to grow 7% in 2026, marking the fastest expansion in the post-COVID era, as companies increasingly seek specialized advice on monetizing artificial intelligence and managing data center energy demands.
The US consulting market is poised for significant expansion in 2026, with projections indicating a 7% growth rate that would represent the fastest pace since the COVID-19 pandemic, according to research from Source Global. This acceleration reflects a fundamental shift in corporate priorities as organizations scramble to capitalize on artificial intelligence opportunities while managing associated challenges.
Consulting industry analysts estimate the US market will reach approximately $260 billion in 2026, up from approximately $243 billion in 2025. This growth trajectory represents a notable acceleration from the 4.5% expansion recorded in 2024 and the projected 5.8% growth for 2025.
The consulting industry's resurgence comes after several years of fluctuating demand following the pandemic's disruption. While many sectors have returned to pre-pandemic growth trajectories, the consulting market's 7% projection for 2026 exceeds current industry averages and signals a new phase of strategic reinvestment among businesses.
"What we're seeing is companies moving beyond experimentation with AI to seeking concrete pathways for monetization," said industry analysts tracking the trend. "Consultants are being engaged not just for implementation support but for developing entirely new business models around AI capabilities."
The growth drivers appear twofold. First, companies across industries recognize the competitive imperative of AI integration but often lack the internal expertise to develop effective strategies. Second, the energy requirements of AI infrastructure have created a parallel need for specialized consulting around sustainable data center development and operational efficiency.
Financial services, healthcare, and manufacturing lead the sectors showing increased consulting expenditure, with AI transformation representing the primary focus area. These industries face unique regulatory and operational challenges that require tailored approaches to AI adoption.
According to Source Global's research, AI-related consulting now represents approximately 35% of total consulting demand, up from just 15% in 2022. This segment is growing at approximately 22% annually, significantly outpacing traditional consulting services.
"Companies are realizing that AI success requires more than just technology implementation—it demands organizational restructuring, talent development, and new performance metrics," noted consulting industry observers. "This holistic transformation is precisely where specialized consultants add value."
The consulting firms themselves are adapting their offerings to meet this demand. Traditional strategy consulting firms have expanded their AI practices, with major players like McKinsey, Bain, and Boston Consulting Group reporting that AI-related work now constitutes 25-30% of their revenue, up from 10-15% two years ago. Meanwhile, specialized boutiques focusing on AI ethics, implementation, and monetization have emerged to capture market share.
Energy consulting has also seen increased demand as organizations confront the substantial power requirements of AI infrastructure. Data centers now account for approximately 2% of global electricity consumption, a figure expected to rise significantly with expanded AI deployment. Companies are seeking consulting expertise to optimize energy usage, explore renewable integration, and navigate increasingly complex regulatory environments surrounding energy consumption.
The 7% growth projection for 2026 represents a notable acceleration and suggests that AI-related consulting will become an increasingly dominant segment of the overall market. Industry analysts project that by 2028, AI and energy consulting could collectively represent over 50% of the US consulting market.
For businesses, the consulting boom presents both opportunities and challenges. While external expertise can accelerate AI initiatives, organizations must carefully select partners with proven track records and avoid the pitfalls of over-reliance on consultants for core strategic functions.
Consulting industry leaders emphasize that successful engagements require deep collaboration between client organizations and external advisors. "The most valuable consulting relationships involve knowledge transfer and capacity building within the client organization," noted one industry executive. "Temporary expertise should enhance, not replace, internal capabilities."
As the AI landscape continues to evolve, the consulting industry's role in shaping enterprise AI strategies will likely expand, making the 2026 growth projection a bellwether for broader technological transformation across the business landscape.
The consulting market's response to AI opportunities reflects broader patterns in the technology adoption lifecycle, where specialized expertise initially commands premium rates before becoming more commoditized over time. For now, organizations with deep AI and energy domain expertise hold significant market leverage, a dynamic likely to persist through 2026 and beyond.
