**Sarah Guo’s $1.3 billion bet against the AI elite**
Sarah Guo, the well-respected venture capitalist behind Conviction, has just made a stunning wager against some of the biggest names in the AI industry. Her firm has quietly taken stakes in startups working on AI safety, a field that’s gained significant traction in recent years.
Conviction has invested in companies like Mosaic, which is developing an AI model that can explain its decisions, and Luminous, a startup working on techniques to detect and prevent AI failures. These investments are a clear sign that Guo is putting her money on a different outcome than the likes of **Anthropic**, one of the leading AI research companies out there.
In November 2025, Anthropic unveiled its **Claude Opus 4.5** model, which was trained on a massive setup of liquid-cooled processors. The model’s release sparked a frenzy in the AI community, with many experts hailing it as a major breakthrough. But Guo and her team have taken a different view, betting against the notion that companies like Anthropic are on the right track.
So, what’s driving Guo’s skepticism? The answer lies in the growing concern over **AI safety**. As models like Claude Opus 4.5 become increasingly sophisticated, there’s a growing risk that they could become uncontrollable. Guo’s investments in startups working on AI safety are a clear acknowledgment of this risk, and her firm’s decision to bet against the AI elite is a bold statement.
**What this means for investors**: Guo’s wager is a stark reminder that the AI industry is still a high-risk, high-reward space. Companies like Anthropic may be making headlines, but the real action is in the startups working on AI safety. If Guo’s bet pays off, it could send a powerful message to investors: the future of AI lies not in the flashiest models, but in the careful, deliberate work being done behind the scenes.
