Sequoia Writes Off Graphcore Stake, Devaluing British AI Chip Unicorn

Executive Signal Summary

British AI chip startup Graphcore has suffered a major setback after its major investor Sequoia Capital wrote its entire stake in the company down to zero. Founded in 2012/2013 by Nigel Toon and Simon Knowles, Graphcore has raised nearly $700 million in venture capital to develop its Intelligence Processing Units (IPUs) as a European challenger to Nvidia. Sequoia first invested in 2017 during a $50 million funding round. Graphcore had also partnered with Taiwanese semiconductor manufacturer TSMC and was repositioning its IPUs for generative AI applications following the ChatGPT hype. Meanwhile, CEO Nigel Toon publicly criticized the UK government's £900 million Exascale program, urging Prime Minister Rishi Sunak to reserve part of the budget for British suppliers such as Graphcore. Commentator Michael Jackson of Multiple Capital said the write-off raises serious questions about the viability of European deep tech and its access to local funding and customers.

AI Stocks Sink as OpenAI Revenue Misses Reported Figure

A person familiar with the matter said the $68 billion figure included gross revenue from partners, making it more comparable to Anthropic. OpenAI also highlighted 77% total run rate growth in Q3 and 107% growth in enterprise business. The company is preparing for a potential IPO, with a valuation of $852 billion, and is in early talks to raise around $30 billion in new funding.

US suspends Microsoft, Adobe from green card labor program

The Trump administration has suspended Microsoft, Adobe, and six other major tech firms—Capgemini, Cognizant, HCL, Infosys, Tata, and Wipro—from the U.S. Permanent Labor Certification program, which facilitates green cards for skilled foreign workers. Secretary of Labor Keith Sonderling cited active federal investigations and alleged fraud, noting that no new or pending applications from these companies will be accepted. Vice President JD Vance accused Microsoft of replacing laid-off workers with H-1B visa holders. Microsoft defended its practices, stating that most U.S. employees are American and that 80% of its H-1B petitions were for existing employees. The announcement was made during a White House summit on H-1B fraud, and the administration also plans to investigate nine universities, including Harvard, Yale, and Stanford, over student visa program abuse.
