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.
