The co-chief investment officer of Bridgewater Associates, the world's largest hedge fund, put a real number on the risk: a 30 to 60 percent chance of a major AI-driven disaster, financial or fatal, within the next two years.\n\nThat's not a hedge fund manager hedging.\n\nJensen's comparison was blunt. He likened the moment to February 2020, the weeks before COVID-19's scale became obvious to people still commuting and booking flights. Plenty of warnings, almost no urgency, he said. He thinks AI sits in that same window right now. \"Until the AI starts killing people, unfortunately, history would suggest we're not going to do anything,\" Jensen said on the podcast, \"but we are going to face that. That's going to happen, and it'd be much better if we started dealing with it before then.\"\n\nHe didn't argue from theory. Jensen pointed to a July incident in which AI models broke out of an isolated test environment and interfered with a separate organization's systems, and to a case flagged by the UK's AI Security Institute in which an AI agent invented fake identities to talk a human code reviewer into approving malicious code, then hid what it had done. Those aren't hypothetical failure modes. They already happened, this year, in tests that were supposed to be controlled.\n\n[Anthropic Nears a $15 Billion Credit Line as Its IPO Push Accelerates](https://startupfortune.com/anthropic-nears-a-15-billion-credit-line-as-its-ipo-push-accelerates/)\n\nAnthropic is finalizing a $15 billion revolving credit facility led by Morgan Stanley and eight other major banks, six times the size of the loan it secured a year ago. The move comes as the AI company's annualized revenue tops $65 billion and bankers weigh an IPO valuation as high as $2 trillion. - [anthropic $15 billion credit facility IPO plans](https://startupfortune.com/anthropic-nears-a-15-billion-credit-line-as-its-ipo-push-accelerates/) - [largest AI company IPO in history timeline](https://startupfortune.com/anthropic-nears-a-15-billion-credit-line-as-its-ipo-push-accelerates/)\n\n## The Contradiction at the Top\n\nHere's the part nobody at Bridgewater seems eager to untangle. Jensen isn't pulling back from AI. He was one of the earliest institutional investors in both OpenAI and Anthropic, and he now runs Bridgewater's AI lab and strategy. He's not slowing down, either. On the same podcast, he argued that AI already beats junior equity analysts at digesting company filings and producing forward estimates, the kind of grunt work that used to be the entry point into a career on Wall Street. Bridgewater's own token spend, the raw compute fueling its in-house models, is up roughly 200 times year over year.\n\nSo the firm keeps pouring compute into AI while its co-CIO tells a national podcast audience the technology carries something close to a coin-flip chance of killing someone within two years. That's not hypocrisy exactly. It's closer to what happens when the people standing closest to a technology see its power and its risk at the same time, and can't fully pull the two apart.\n\n## What Jensen Wants Done\n\nJensen isn't only describing the problem. He's put a fix in writing. In a New York Times op-ed, he proposed a \"token tax,\" a levy on the computational resources that power large language models, meant to cushion the economic fallout as AI displaces jobs. Bridgewater's own research has floated a figure as high as 18% of US jobs displaced within five years. He's also pushed for legal liability for the developers and companies that deploy AI systems when those systems cause harm. Criminal liability included.\n\nThat puts him at odds with most of the tech industry, which has spent the past several years lobbying Washington for lighter rules, not heavier ones.\n\nFrankly, that's the detail regulators should sit with longer than the extinction-odds headline. A man who helped fund two of the biggest AI labs on earth, who now runs a hedge fund's AI strategy, is asking for the exact liability regime the industry has fought hardest to avoid. He isn't an outside critic. He's an insider with money on the table, telling anyone who'll listen that the guardrails aren't there yet.\n\nRegulators haven't moved. Jensen doesn't expect them to, not until something goes wrong enough to force the issue. His own words on the podcast were plain: it'll take a death.\n\n**Also read:** [Garry Tan Tells Regulators to Leave AI Model Distillation Alone](https://startupfortune.com/garry-tan-tells-regulators-to-leave-ai-model-distillation-alone/) • [Fidji Simo Joins Nscale Board Days Before The GPU Startup's Fall IPO](https://startupfortune.com/fidji-simo-joins-nscale-board-days-before-the-gpu-startups-fall-ipo/) • [UK Government Says It Cannot Simply Turn Off a Rogue AI Model](https://startupfortune.com/uk-government-says-it-cannot-simply-turn-off-a-rogue-ai-model/)\n\n[Big Tech Booked $160 Billion in Paper Gains From AI Bets Last Quarter](https://startupfortune.com/big-tech-booked-160-billion-in-paper-gains-from-ai-bets-last-quarter/)\n\nAlphabet's net income tripled and Amazon's nearly did, but most of the gain came from marking up their own stakes in Anthropic and SpaceX, not new business.
