Why I write this
Every week I have hundreds of conversations with people working at the edge of machine learning and quantitative finance, and I spend hours digging into the research, papers and announcements behind them. Most of what I learn never makes it past those conversations. The Weekly Frontier is my way of giving something back to this community: the ideas and developments that matter most, distilled into one considered read each week.

This week's edition · Week ending 4 October 2026 28 Sep – 4 Oct 2026My five top market insights from last week in the quant and ML/AI worlds:
- The race for frontier AI talent in the quant world continues as Citadel names Google DeepMind as a direct recruiting target.
- Anthropic pursues a $2 trillion IPO on a $518bn compute commitment.
- OpenAI lead researcher resigns due to ‘broken culture’ as its safety function implodes.
- Meta Superintelligence Labs make progress on open maths problems using AI, showing how important maths is becoming in frontier AI.
- GPT-6 Astra scores 62.7% vs 98.6–99.9% on the same benchmark depending on the testing set-up, raising questions over AI benchmark results.
That's just a sneak peek. The full edition goes much deeper across 10 sections, from the week's most important research papers to what's moving in quant, Big Tech and academia.
