Deloitte Omnia Agentic Intelligence: 85,000 Auditors Get a Network of AI Agents That Talk to Each Other
The new Deloitte Omnia agentic intelligence network stitches together multiple AI agents into a single co-ordinated system across the firm’s global audit and assurance platform. The announcement, made on 24 June 2026, gives what Deloitte says are 85,000 audit and assurance professionals a fundamentally different way of working. Agents no longer operate in isolation. They share data, hand outputs to one another, and execute entire audit sub-processes without requiring a human prompt at every step.
This is not a chatbot grafted onto an existing workflow. It is a multi-agent orchestration layer built into the core of a platform that has underpinned Deloitte’s audit delivery since 2015.
What Deloitte Omnia Agentic Intelligence Actually Does
The network handles four core functions. Risk factor identification, where agents scan financial and operational data to flag anomalies that could indicate material misstatement. Context-aware assistance that combines Deloitte’s proprietary knowledge base with real-time prompts to support auditor decision-making. Preliminary procedure execution covering data extraction, evidence gathering, documentation drafting, and initial conclusion formation. And regulatory compliance checks that cross-reference audit work against current disclosure and reporting requirements.
The architecture is modular. One agent surfaces a red-flag pattern in client data. A compliance-focused agent evaluates that finding against regulatory standards. A drafting agent then prepares preliminary audit notes for a human reviewer. The agents co-ordinate across these steps rather than operating as disconnected tools.
Deloitte built the entire network with its internal engineering teams rather than licensing from a third-party vendor. All capabilities sit under the firm’s Trustworthy AI framework, which embeds governance, controls, and compliance throughout the technology’s lifecycle.
Eleven Years of Platform Investment
Omnia launched in 2015 as a cloud-based audit platform. It has been updated continuously since, winning the inaugural AI Innovation Initiative of the Year award at the 2024 International Accounting Forum in London for its early generative AI capabilities.
In July 2025 Deloitte announced a further round of AI investments, adding purpose-built large language models, GenAI-powered drafting tools for audit communications, and enhanced research capabilities for technical accounting queries. The firm says its 85,000 auditors were already running more than three million AI prompts per year through the platform by that point. Deloitte also rolled out purpose-specific chatbots tailored to audit workflows and launched a GenAI and advanced AI applications certification programme across the organisation.
The June 2026 release builds directly on that foundation. Will Bible, Deloitte Global Audit and Assurance Digital Products leader, described Omnia as having evolved into a unified agentic platform where professionals, data, methodology, and AI operate together. He said the firm’s technology now absorbs time-intensive workstreams to elevate critical thinking and analysis.
The upgrade also introduces a tutor mode that delivers on-demand micro-training to auditors in the context of whatever task they are performing. That sits alongside broader upskilling through the Deloitte AI Academy and Scout, an AI-driven learning assistant for personalised professional development. The firm reports that more than 120,000 professionals have completed AI training through these programmes, though that figure is not independently verified.
How Deloitte Omnia Agentic Intelligence Fits the Big Four Arms Race
Every major firm now has an agentic AI platform. The competitive dynamics are intensifying on a quarterly basis.
EY launched EY.ai, giving 80,000 tax professionals access to 150 specialised agents handling tax research, compliance document analysis, and return preparation. The firm says it has advanced more than 1,000 agents into development or production, with plans to scale to 100,000 by 2028. That effort is backed by what EY reports as more than $1 billion in annual AI investment.
PwC introduced Agent OS in March 2025, deploying what the firm claims are 25,000 intelligent agents across client operations through partnerships with Salesforce, CrewAI, and AWS.
KPMG rolled out Workbench in June 2025, a multi-agent collaboration platform built with Microsoft that connects 50 agents with a heavy emphasis on orchestration, transparency, and audit-trail accountability.
The hiring data underlines the shift. A Financial Times analysis of more than 50,000 job listings found that AI-related roles made up almost 7% of postings across the Big Four. Audit roles accounted for under 3%. Big Four graduate openings fell 44% year-on-year in 2024.
The Margin Question Nobody Is Saying Out Loud
Every firm frames its AI investment as a quality and trust initiative. Deloitte’s Dipti Gulati, chair and chief executive officer of Deloitte and Touche LLP, said the combination of advanced technology and professional judgment enables the firm to deliver confidence at scale. The language is near-identical across all four firms. Human-led, AI-powered, professional judgment preserved.
To be sure, there is a genuine quality argument. Broader data coverage, more consistent documentation, and faster anomaly detection are real improvements to audit rigour. But the economic logic underneath the messaging is harder to ignore. Audit margins have been under pressure for years. Automating the preliminary procedures that consume thousands of junior hours each busy season is not just a quality play. It is a margin play that happens to improve consistency along the way.
EY has already hinted at a shift from hourly billing to an outcomes-based model. PwC expects new hires to take on manager-level responsibilities within three years, overseeing AI that handles routine tasks. KPMG’s global AI workforce lead has said explicitly that the firm wants juniors to become managers of agents rather than performers of the work those agents now handle.
What This Means for the Profession
The Deloitte Omnia agentic intelligence upgrade is one step in a longer transformation, but it is a significant one. When a connected network of agents can execute preliminary procedures, draft documentation, and flag compliance gaps across a global platform serving 85,000 professionals, the entry-level audit role starts to look very different.
For CFOs and audit committees, the more immediate question is whether pricing follows capability. If agent-driven workflows deliver faster turnaround and broader coverage, the justification for billing at traditional rates becomes harder to sustain. No firm is prepared to say that publicly yet. The technology is making the argument for them.
The race across the Big Four is no longer about whether AI belongs in audit. It is about who operationalises it fastest and who reprices the service model first.
