• Quant employment verification — CONFIRMED. Aron Thomas held actual quantitative-finance roles at Jane Street (a quantitative trading firm / market maker), not merely a student programme: LinkedIn enrichment records a Quantitative Trading Intern role in 2022 and a Quantitative Trader role spanning 2022-2025 in London. Independently of the index, Bloomberg reporting (republished by Business Standard, Aug 2025) states that Aron Thomas and Charles Guo 'both left Jane Street earlier this year to join Anthropic', confirming past Jane Street employment through a named press source. Identity is supported by multiple primary sources: IMO/IOI results as a UK contestant, Dame Alice Owen's School news, Cambridge Union and Cambridge SU records, all matching the London/Cambridge maths profile. Employer classification: Jane Street is a quantitative trading firm; role types were internship (2022) and full-time trader (2022-2025). Status therefore CONFIRMED.Aug 8, 2025
