Frontier labs just became consulting firms. Anthropic-Blackstone $1.5B and OpenAI's Deployment Company.

Anthropic and OpenAI both moved into the consulting business the same week. On May 4, 2026, Anthropic announced a $1.5 billion joint venture with Blackstone, Hellman & Friedman, and Goldman Sachs. CNBC and Fortune carried the news with the same framing: Anthropic is taking direct aim at the consulting industry.

The structure of the Anthropic JV is the part to read carefully. Anthropic, Blackstone, and Hellman & Friedman are each contributing approximately $300 million in day-one capitalization. Goldman Sachs is in for $150 million. Apollo Global Management, General Atlantic, Leonard Green, GIC, and Sequoia Capital also joined the cap table. The new entity is a standalone firm with Anthropic engineering resources embedded directly inside its operating team. The model mirrors Palantir's forward-deployed-engineer playbook from a decade ago.

The same week, OpenAI launched its parallel Deployment Company. The structure is similar: Wall Street PE-backed, engineers embedded inside portfolio firms, model usage plus implementation billed on a single invoice. TechCrunch covered both launches under a single banner: "Anthropic and OpenAI are both launching joint ventures for enterprise AI services."

The structural target is the consulting margin. McKinsey, Accenture, and Deloitte have spent the last three years selling AI implementation services where the model is procured separately from the consulting firm. The new lab-led JVs collapse those two line items into one. The lab makes the model. The lab embeds the engineer. The lab keeps the spread.

For the consulting incumbents, the threat is bigger than the dollar value of these JVs. It is the precedent. Every Fortune 500 buying AI implementation services in 2027 will price the lab-direct option against the consulting-firm option. The labs control the underlying model and can therefore price the bundled offer below the consulting firm's cost of goods. The consulting incumbents have not yet announced a structural response. They will have to.

What to watch: whether Accenture or Deloitte announces an acquisition of a frontier-lab partner or a competing JV structure within 90 days. Whether McKinsey loses a publicly disclosed AI-implementation engagement to one of the new JVs. Whether IBM, the legacy services name with the longest AI track record, sells off its consulting arm or doubles down on it.
