Polymarket POL drained from admin key on Polygon; withdrawals paused
Polymarket said suspicious activity on Polygon was not a core smart-contract hack. Instead, a compromised private key tied to an internal admin/operations wallet was used to drain POL. The estimated loss is about $520,000–$700,000 worth of POL, transferred to 15–16 wallet addresses and routed through multiple services.
Investigators including ZachXBT flagged abnormal outflows, with analytics firms (Bubblemaps, Lookonchain, PeckShield) confirming a pattern peaking at roughly 5,000 POL every 30 seconds. Polymarket engineering VP Josh Stevens said the stolen key was reportedly around six years old and that market resolutions and user assets should remain unaffected.
In response, Polymarket paused withdrawals and started rotating keys across backend services. For POL traders, the key risk is short-term sell pressure: if the stolen POL is converted via faster non-custodial routes, it could add volatility even if user balances and settlement contracts are not directly impacted. Traders should watch for permission revocations, address/key rotations completion, and a final confirmed POL loss figure.
Bearish
This is framed as an isolated admin/operations wallet private-key breach rather than a user/settlement contract exploit, which should limit long-term damage to Polymarket’s core market functions. However, POL was drained at high speed (around 5,000 POL every 30 seconds at the peak) and the funds were dispersed and routed via multiple services. That raises the probability of near-term conversion into sell orders, which can pressure POL on Polygon.
The immediate market reaction risk is increased by the “withdrawals paused” headline and uncertainty around the final confirmed loss and recovery status. In the short term, this typically turns into bearish tape (wider spreads and faster downside if stolen POL reaches liquidity). Longer term, sentiment can stabilize if Polymarket completes key rotations, revokes relevant permissions, and confirms that user assets and market resolutions were unaffected—reducing the chance of a second wave.
