OpenAI Plans to Almost Double Its Headcount This Year, FT Says - Bloomberg.com
OpenAI is planning to nearly double its workforce from 4,500 to 8,000 employees by the end of 2026, according to the Financial Times, which cited two people with knowledge of the matter. The hiring push is the most concrete sign yet that OpenAI is treating scale — of people, not just compute — as a competitive weapon.
The expansion spans product development, engineering, research, and sales. But the most revealing detail in the FT's reporting is a new category of hire: specialists in "technical ambassadorship," whose job is to help enterprise clients actually use OpenAI's tools. That's not a research bet. That's a revenue bet. It signals that Altman sees winning in the enterprise as a distinct problem from winning on benchmarks.
The backdrop matters. In early December 2025, Altman issued an internal "code red," halting non-core projects and redirecting teams to respond to Google's Gemini 3 — which had gained 200 million users in three months and was closing the capability gap with GPT-series models. The code red produced a new reasoning model within weeks. Now the hiring surge suggests OpenAI is moving from crisis response to sustained scale.
Three weeks before this hiring plan became public, OpenAI closed a $110 billion funding round — $50 billion from Amazon, $30 billion each from Nvidia and SoftBank — at a post-money valuation of $840 billion. That capital made the hiring math possible. At current San Francisco compensation rates, 3,500 new technical hires runs well into the billions annually. The money is there.
The FT frames the competitive target explicitly: Anthropic. At roughly 1,000 employees in 2025, Anthropic has been building with a smaller, research-concentrated team — a deliberate bet on depth over breadth. OpenAI's plan, if executed, would push its headcount to roughly 8x Anthropic's 2025 size. That's not catching up to Anthropic; that's an attempt to make Anthropic's model of competition structurally irrelevant.
A caveat worth flagging: OpenAI did not confirm the report, and Reuters noted it could not independently verify the figures. The story rests on two anonymous sources to the Financial Times. The $840 billion valuation figure, however, is confirmed by the February funding round — which OpenAI announced publicly.
What this means for builders and investors: OpenAI is not behaving like a company that thinks it has won. The code red, the record-breaking funding round, and now the aggressive hiring plan are three signals in the same direction — OpenAI is running scared of Google and aware that Anthropic is not going away. For enterprise teams evaluating AI vendors, the technical ambassadorship push is worth watching. That role does not exist to sell ChatGPT. It exists to embed OpenAI deeply enough into enterprise workflows that switching becomes painful.
The IPO, expected later in 2026, gives all of this a hard deadline. Altman needs to show revenue growth and enterprise penetration before the company goes public. The hiring plan is partly a product strategy and partly an investor narrative.
