The AI Power Play: What Are the Big Four Up to?

KPMG, Deloitte, EY, and PwCare going all-in on artificial intelligence (AI). They’re building smart platforms that don’t just help their teams,they actually do the work. Here’s what’s new:

KPMG’s New AI Tool

KPMG just launched “Workbench,” an AI system that runs across tax, audit, and advisory services. It links up with their existing tools—like Clara for audit and Velocity for consulting—to give faster, smarter results.

EY and Nvidia Team Up

EY is giving its 80,000 staff AI assistants to help with everything from reading documents to doing tax work. They’re also working closely with Nvidia and Google Cloud—just like Deloitte and PwC.

Big Money, Big Moves

PwC says this is the start of a “golden age” in accounting, with partners investing their own money into AI. Deloitte just launched “Zora AI” to help with finance and marketing. Everyone’s racing to be first.

Auditing AI Systems

All four firms now offer something new: AI audits. These are checks to make sure companies’ AI tools are safe, fair, and accurate. Industries like healthcare, finance, and driverless cars are already lining up for these services.

What’s the Risk?

AI still can’t replace human judgment. EY warns that full trust in AI systems will take time. And mid-sized firms are also using this tech to compete—so the Big Four’s dominance is being challenged.

So What Does This Mean for You?

✅ Even small firms can now use powerful tools—if they adopt the right tech
✅ Your clients may soon ask if your firm offers AI-backed services
✅ AI can save you time—but it’s your advice, judgment, and oversight that clients will still pay for

AI is no longer just hype, it’s already changing how tax, audit, and advisory work gets done. Whether you're in a big firm or running your own practice, the question is: are you using AI, or falling behind?
