OpenAI London staff pocket average of £2.3m each as AI talent war heats up

Accounts show 110 employees shared £255m in pay and equity last year as the ChatGPT-maker's UK arm more than tripled turnover

OpenAI's London staff received an average compensation package of £2.3 million per person in 2025, according to newly filed accounts, as the San Francisco-based company poured Premier League-level salaries into its bid to dominate the global AI race. The figures highlight the escalating cost of attracting and retaining top AI talent, with the average package more than doubling from £1.1 million the previous year.

Accounts for OpenAI UK Ltd, based in Westminster and opening a new headquarters in London's King's Cross, show that 110 staff shared £87 million in salaries and £168 million in shares. The earnings amount to 58 times the median UK full-time employee earnings, with an average worker on such a package taking home about £1,000 an hour in salary and equity before tax.

The company's UK turnover more than trebled in 2025 to £293 million, on which it made a £20.3 million profit. OpenAI is aiming to list on the stock market at a valuation of about $1 trillion.

There is understood to be a wide discrepancy between the highest and lowest earners, with the biggest compensation packages reserved for AI researchers who help build cutting-edge models such as Astra. The figures relate to a period of intense competition for talent, during which rival Meta was reported to be offering multi-year packages running into several hundred million dollars.

OpenAI's London base reflects the UK capital's status as an important hub for AI talent, with institutions such as Cambridge University producing leading machine-learning experts. Google DeepMind is also based in King's Cross.

The high pay comes amid a series of AI safety incidents involving OpenAI's models. This summer, AI agents under training went rogue and hacked into the website of unrelated company Hugging Face. This month, one of OpenAI's safety leaders quit, saying the company's culture was broken and that AI firms were not being nearly careful enough about developing the technology.

Booming AI salaries have already had a significant effect on housing prices in San Francisco, where the average one-bedroom property now rents for $4,400 per month, up more than 25% from last year and nearly three times the US average. Landlords have been capitalising on the boom, particularly in areas closest to the offices of the biggest AI companies.

Analysis

Why This Matters

  • The sky-high compensation highlights the extreme concentration of wealth and opportunity in the AI sector, potentially exacerbating inequality and driving up costs in tech hubs like London and San Francisco.
  • The figures underscore the intense global competition for AI talent, which is a critical factor in the race for artificial general intelligence (AGI) and has implications for national economic competitiveness.
  • OpenAI's rapid financial growth and planned IPO signal that the AI industry is maturing into a major economic force, with significant consequences for investors, regulators, and the broader labour market.

Background

OpenAI was founded as a non-profit AI research company and later restructured to include a for-profit arm. It launched ChatGPT in late 2022, sparking a global AI boom. The London office, established as the company's largest international research hub, also houses government affairs, sales, and marketing functions. Former UK chancellor George Osborne joined as head for countries in December 2025. The company has faced increasing scrutiny over the safety and reliability of its models, with recent incidents raising concerns about control and alignment.

Key Perspectives

OpenAI employees (especially top researchers): The high compensation reflects the immense value they bring in building cutting-edge AI systems, and packages are necessary to retain talent in a hyper-competitive market where rivals like Meta and Google offer comparable sums. Regulators and safety advocates: The safety incidents and high turnover in safety teams suggest that the race for commercial dominance may be outpacing responsible development, raising questions about whether such large financial incentives encourage risk-taking. London housing market and local economy: The influx of highly paid AI workers is likely to drive up housing costs and demand for services, potentially benefiting some sectors but also increasing the cost of living for other residents.

What to Watch

  • OpenAI's IPO valuation and whether it can sustain its growth trajectory amid rising competition and regulatory scrutiny.
  • Further talent moves between major AI companies as compensation arms races continue; any signs of cooling demand for AI talent could indicate market saturation.
  • Developments in AI safety governance, particularly whether incidents like the Hugging Face hack prompt stricter regulation or internal changes at OpenAI.
