Susquehanna International Group

Susquehanna International Group's Top Stability & Growth Strengths

Strong Hiring & Retention: Ongoing openings across trading, technology, and operations, plus internship pipelines into 2026–2027, indicate sustained intake and future class backfills typical of growth firms. Third‑party and company materials cite roughly 3,800–4,000+ people by late 2025 with Hong Kong growing, signaling headcount expansion.

Market Expansion: Subleasing roughly 74,000 square feet at 30 Hudson Yards in 2024 with a path to a direct lease suggests a scale‑up move for headcount and client proximity in a key market. A public office roster spanning North America, Europe, and APAC (e.g., New York, Dublin, London, Sydney, Hong Kong) reinforces a multi‑hub global model.

Future-Ready Strategy: Early, recurring campus pipelines through 2027 and continued publicizing of multi‑region offices point to long‑horizon investment in quantitative research, technology, and market access. The combination of a larger NYC presence and continued global hiring since mid‑2024 suggests capacity building to capture trading and market‑making opportunities into 2026.
