What People Are Saying About Simplex Trading

  • Market Expansion: Recent leadership appointments are explicitly tasked with expanding partnerships and moving into new products and geographies, and ongoing 13F filings signal continued participation at scale. Product-level market‑maker designations and visible industry participation further point to an expanding footprint.
  • Product Line Growth: Moves beyond core U.S. equity options—such as building wholesale options capabilities via an affiliate and adding Eurodollar options—indicate a broader offering set. Designated/lead roles on specific exchange‑listed products reinforce growth within targeted product categories.
  • Strong Hiring & Retention: Active postings for traders and engineers alongside an operational careers portal suggest ongoing team build‑out. Consecutive Built In “Best Places to Work” recognitions align with investment in talent brand and retention.
