Senior Counsel, Corporate & Commercial

Polymarket•New York, NY

About The Position

Polymarket is the world's largest prediction market platform. We enable individuals to express views on real-world events by trading on outcomes across politics, economics, sports, culture, and current affairs. Built as a peer-to-peer marketplace with no centralized "house," Polymarket aggregates diverse opinions into transparent, market-based probabilities that reflect collective expectations about the future. We're growing fast — both in terms of volume ($21B traded in 2025) and adoption as an alternative news source. Our ambition is to become a ubiquitous beacon of truth in global media and we need your help adding fuel to the fire. We're looking for a detail-oriented, business-savvy senior counsel to join our legal team in a supporting role across commercial and corporate matters. You'll work closely with our finance and business teams to move deals forward, keep corporate housekeeping in order, and handle a steady volume of substantive legal work with minimal hand-holding. This is a great fit for someone who is ready to own a real workload in a fast-moving environment.

JD and admitted to practice in at least one U.S. jurisdiction
Roughly 5-6 years of experience with a mix of firm and in-house time (one year or more in-house required)
Ability to work through a contract efficiently, with enough deal exposure to have developed good instincts
Comfortable operating without a lot of direction once you understand the assignment
Organized, thorough, and communicative — you take ownership of your workload and follow through without needing to be chased
Genuinely interested in the substance of what the business does, not just the contracts sitting on top of it

Background in fintech, crypto, tech, or a similarly fast-paced or regulated industry
Familiarity with data agreements, API or platform terms, or marketplace business models

Work alongside senior commercial counsel on more complex or strategic deals, taking on meaningful portions of the work rather than just administrative tasks
Assist with entity maintenance, board and governance matters, and general corporate projects as they arise
Help maintain and improve contract templates and internal processes
