Simplify's Take

What believers are saying

  • Old Mission sponsored ICI, Cboe, STA, and PyCon in May 2026.
  • The firm is reportedly subleasing 70,000 square feet at 167 North Green Street.
  • 2026 recruiting remains active, including junior ETF sales trader roles and Harvard postings.

What critics are saying

  • Single-dealer platform launch slips beyond 2025, wasting hiring and ceding clients to Jane Street.
  • ETF market-making profits compress if Citadel and Jane Street tighten spreads faster.
  • Old Mission's Illiquid-ETF niche concentrates revenue; a risk-off ETF freeze hits inventory hard.

What makes Old Mission unique

  • Old Mission owns ETF liquidity in hard-to-price, illiquid products, not plain-vanilla flow.
  • The firm held 976 U.S. equity positions worth $4.2B in Q1 2026.
  • Eugene Davidovich’s 2025 platform hire signals direct bilateral access to proprietary liquidity.
