Key Takeaways
  • • Situational Awareness, the hedge fund run by 24-year-old Leopold Aschenbrenner, may face compliance restrictions on trading Anthropic stock once Anthropic completes an IPO, according to compliance consultant Greg Worsfold cited in the article.
  • • Aschenbrenner's Silicon Valley network, many of whom are at Anthropic, was a factor in the fund's survival after it ran into trouble in June, alongside Citadel taking over and liquidating the fund's public equity portfolio.
  • • Under likely restrictions, Aschenbrenner could be subject to blackout periods around earnings releases and need documentation showing investment theses were built solely on public information.
  • • McKinsey & Co. is trialling an AI avatar role-play interview for entry-level candidates starting this autumn, and the article expects similar tools may reach banking interviews.
  • • The article also reports Bank of America's $1.2bn fine appears disproportionate, Perella Weinberg and Piper Sandler ended merger talks, and Antoine Iskander is moving from Millennium to Balyasny.
Summary
According to eFinancialCareers, Leopold Aschenbrenner's Situational Awareness fund was rescued in June when it ran into trouble, helped by his network of Silicon Valley contacts, many at Anthropic, and his valuable pre-IPO stake in Anthropic. Citadel, led by Ken Griffin, also took over the fund's public equity portfolio and liquidated it quickly, avoiding exposure to a later CoreWeave sell-off.

The article argues that those relationships could become a compliance problem. Anthropic must go public for the fund to realise the value of its stake, and once it is listed, close ties to company insiders become a regulatory burden rather than an edge. Compliance consultant Greg Worsfold is quoted as expecting Aschenbrenner to restrict trading in Anthropic and possibly other companies where he has close relationships. Measures could include blackout periods around earnings releases and a paper trail demonstrating that investment theses rested entirely on public information. The article notes this is a future issue, as Aschenbrenner may not sell soon, but says it should be taken seriously, pointing to past tech booms in which similar "no conflict, no interest" arguments did not end well.

Elsewhere in the newsletter, McKinsey & Co. is trialling an AI avatar that simulates stereotypical client personalities for entry-level candidates, with a ten-minute conversation beginning this autumn. The tool is designed to test how candidates notice information and think on their feet rather than deliver prepared answers. The article suggests banks could adopt similar tools, potentially in more aggressive forms for sales and trading or capital markets roles, but expects use to be limited to entry-level roles and internships.

Other items include the article's view that the $1.2bn fine on Bank of America appears disproportionate to the technical alerting-system breaches involved, per Bloomberg. Financial News reported Citi rainmakers were pushed to cross-sell wealth management clients. Perella Weinberg and Piper Sandler ended merger talks after a critical mass of Perella's top talent did not support the deal, according to the FT. Antoine Iskander, who had discussed spinning his Millennium pod into an independent manager, is joining Balyasny instead, per Bloomberg.
