Gondor shifts Polymarket lending to portfolio-backed margin model

The transition follows a seven-month beta phase that involved 1,000 active traders selected from a 150,000-person waitlist. During that testing period, the platform relied on isolated lending, which treated each prediction market position as a separate entity. This structure created binary risk, forcing the company to impose restrictive borrowing caps and mandate early loan closures to protect against sudden market devaluations.

By adopting a cross-margin model, Gondor intends to lower financing costs and expand the variety of markets eligible for credit. The system functions similarly to traditional prime brokerage accounts, where the total portfolio value determines borrowing capacity. While the private rollout begins next week, the company has yet to disclose specific borrowing rates, collateral requirements, or liquidation thresholds. A public launch is slated for September, marking the first time the model will operate outside of the restricted beta environment. The development builds on capital secured in an August 2025 funding round led by Maven11 Capital, with backing from firms including Polymesh, Rhino.fi, and Futuur.
