"85% accuracy on Wall Street will get you 100% fired." Brett Caughran (@FundamentEdge) has managed analysts at Citadel, D.E. Shaw & tiger cub funds. His take on AI and the future of junior analysts: "There's almost no better time to be starting a career as a fundamental investor. These tools let junior investors get to the juicy part of the investment process more quickly." We cover: - Why the junior analyst role is transforming faster than any point in the last 20 years — and why the juniors who adapt will reach the real work of investing years sooner - The old grunt work that's already dead — and what's replacing it - Why billion-dollar funds won't cut analyst headcount, but the job description is changing dramatically - “Should I still learn Excel modeling?" — yes, because you can't debug what you don't understand - Why creativity & tenacity are becoming the new differentiators over raw quantitative skill - How multi-manager alpha factories scaled from $10B to $60B+ while sustaining double-digit returns — proof that more information hasn't compressed alpha - Why reading a 10-K with pen and paper still matters even when AI can summarize it in seconds - The most underrated skill in the best investors he's worked with: genuine curiosity Thanks so much to Brett (@FundamentEdge) for coming on Odds on Open! Highlights: 00:00 Intro 01:29 Frameworks for developing a differentiated variant perception 05:16 Financial drivers vs. narrative cycles: The Focus 5 framework 08:29 Analyzing the stock vs. business: Bayesian updating in public markets 12:52 AI as an intellectual power tool vs. consensus "alpha slop" 17:21 Accelerating the hunch-to-hypothesis pipeline with AI sniff tests 21:52 The evolution of junior analysts: From data entry to primary research 28:46 Why market microstructure and behavioral alpha prevent index efficiency 38:44 Training junior analysts: Earning the right to use power tools 48:28 LLMs as orchestration tools for human primary research 54:55 Teachable scientific process vs. revealed investment judgment 57:54 Common threads across Multi-Managers, Single Managers, and Tiger Cubs 59:49 Curiosity as a meta-skill and the art of system thinking


SpaceXAI and @cursor_ai are now working closely together to create the world’s best coding and knowledge work AI. The combination of Cursor’s leading product and distribution to expert software engineers with SpaceX’s million H100 equivalent Colossus training supercomputer will allow us to build the world’s most useful models. Cursor has also given SpaceX the right to acquire Cursor later this year for $60 billion or pay $10 billion for our work together.

The guy who allegedly threw a Molotov cocktail through Sam Altman’s window seems to have been an adherent to pause/stop AI. I am entirely unsurprised and have been warning about this for a long time now. I am fine with people advocating for their preferred policies—if that includes a “pause” on AI development, so be it, even if I disagree strongly. But the obvious reality is that the rhetoric of this community—which to be *extremely clear*, is a very small and non-representative subset of the AI safety community—is closer to ecoterrorism than it is to a more typical activist policy effort. Every time I have written about existential risk in recent months, I have been called a mass murderer. People with ⏹️ and ⏸️ in their handles confidently tell me that I am murdering my own baby boy and every other child on the planet. Another prominent one of these people has called me a traitor to America. I only use my own examples because I know them; this rhetoric is representative of how this fringe of the AI safety world communicates with everyone. The rhetoric of the pause/stop crowd is out of control and it has gotten worse with time. This rhetoric always had the potential to cause violence and now this seems to be no longer hypothetical.






Absolutely wild that Anthropic was founded less than five years ago is already devouring an entire software category and is worth more by market cap than all of these blue-chip SaaS companies combined: • $CRM $154B • $CRWD $96B • $NOW $85B • $SNOW $43B
