Simplify's Take

What believers are saying

  • Eugene Davidovich joined in September 2025 to launch electronic execution by year-end.
  • The firm planned a 70,000-square-foot Fulton Market expansion in July 2026.
  • September 2026 campus recruiting at MIT, Berkeley, CMU, Texas, and Brown signals hiring momentum.

What critics are saying

  • Jane Street and Citadel Securities can compress ETF spreads faster than Old Mission.
  • A 2026 platform launch miss would waste Davidovich's hire and delay revenue diversification.
  • If Vanguard and BlackRock keep tightening ETF spreads, Old Mission's niche evaporates.

What makes Old Mission unique

  • Old Mission specializes in illiquid ETFs, a niche competitors still under-serve.
  • Its 2025 single-dealer platform extends that ETF liquidity into direct client execution.
  • SEC-registered broker-dealers and Chicago trading talent support complex, automated market making.
