Headquartered in Bala Cynwyd, Pennsylvania, the firm employs more than 3,500 people across 17+ offices worldwide and operates as one of the largest options market makers globally. SIG's businesses span Quantitative Trading, Predictions, Institutional Sales, Growth Equity (Susquehanna Growth Equity / SGE), Sustainable Investments, Asia-focused Venture Capital (notably an early and large stake in ByteDance), and the River's Edge promotional arm. SIG does not operate a public developer portal, expose external trading APIs, or publish open-source repositories under a public GitHub organization; all technology is internal to the trading and quantitative research platform. Public surface is limited to sig.com (company / careers / insights), the SGE site, and corporate communications. created: '2026-05-23' modified: '2026-05-23' specificationVersion: '0.19' apis: [] common: - type: DomainSecurity url: security/susquehanna-international-group-domain-security.yml - type: Website url: https://sig.com/ - type: About url: https://sig.com/about/ - type: Careers url: https://sig.com/careers/ - type: TechnologyCareers url: https://sig.com/careers/technology/ - type: QuantitativeResearchCareers url: https://sig.com/careers/quantitative-research/ - type: TradingCareers url: https://sig.com/careers/trading/ - type: Offices url: https://sig.com/about/offices/ - type: Insights url: https://sig.com/insights/ - type: Contact url: https://sig.com/contact/ - type: PrivacyPolicy url: https://sig.com/privacy-policy/ - type: TermsOfService url: https://sig.com/terms-of-use/ - type: SusquehannaGrowthEquity url: https://www.sgep.com/ - type: SusquehannaPrivateEquity url: https://www.sigpac.com/ - type: GitHubOrganization url: https://github.com/sig-com description: Private/empty GitHub organization.
