Leading UK tech investor warns of'disconcerting' signs of AI stock bubble Wed 1 Oct 2025 07.07 EDTFirst published on Wed 1 Oct 2025 06.22 EDT A leading British tech investor has described soaring valuations of artificial intelligence companies as "disconcerting", amid concerns of an AI stock market bubble. James Anderson was an early backer of Tesla, Amazon and China's Tencent and Alibaba, generating vast returns for Baillie Gifford's flagship fund. Now at the Italian investment company Lingotto, Anderson said he had not seen signs of an investment bubble until recently, when the ChatGPT developer, OpenAI, and its rival Anthropic announced hefty valuation increases.

The U.K. is gaining in popularity as a great place to start a tech firm. The country is quickly catching up to China on the tech investment front, with VC investments reaching a record of $15 billion in 2020, according to TechNation. A global health crisis notwithstanding, London remained a favorite for investors. U.K. cities made up a fifth of the top 20 European cities, with names such as Oxford, Dublin, Edinburgh and Cambridge rising to the fore in 2020. Bristol proved especially popular among tech investors last year -- local businesses raked in an impressive $414 million in 2020, making it the third-largest U.K. city for tech investment.

Vinod Khosla once proclaimed that machines will replace 80 percent of doctors, which prompted waves of backlash from the medical community. Never one to shy away from controversy, the venture capitalist went a step further when I interviewed him last month for a podcast hosted by Silicon Valley biotechnology startup Color Genomics. "The role of the radiologist will be obsolete in five years," he said. In Khosla's view, sophisticated algorithms are better than specialists at spotting potential problems in medical images, like x-rays and CT scans. "There's no reason a human should be doing it," he says, adding that computers can rapidly shift through thousands of scans to evaluate possible diagnoses and potential treatments, as well as ingest the latest medical research.

Led by some of the world's largest biopharma companies and tech-focused venture capitalists, these investments are backing efforts to speed drug discovery, improve tests and treatments, and further medical research. For now, most of the investment is focused in the diagnostics/tools (Dx/Tools) sector. A Silicon Valley Bank analysis last month found that 44 venture-backed deals raised $2.2 billion between 2015 and the first half of 2017 for Dx/Tools companies that use AI/ML as part of their underlying technology. For our analysis, SVB segmented Dx/Tools into three subsectors: Dx Tests (yes/no test results), Dx/Tools Analytics (actionable data analytics to help direct treatment), and R&D Tools (research equipment and services for biopharma and academia). These deals include multi-$100 million financings for three companies: GRAIL, Guardant Health, and Human Longevity.

Science fiction has long cautioned us that the rise of artificial intelligence will likely mean the end of humanity. The Matrix, Terminator, Blade Runner…the list goes on. But in the real world, while some are concerned about artificial intelligence in 2017, analysts see huge potential in the industry for some key AI companies. In fact, AI technology will be a key driver of some of the biggest tech companies as it continues to develop. And the AI wars have only just begun. And no, not against humans, but rather between tech giants jostling for dominance in what is one of most promising developments in the tech world.
