# Deploy Market

> Deploy a new lending market for a stock token

Deploys a complete lending market (oracle, interest model, insurance fund, and market contract) through the factory. Returns the unsigned factory call for you to sign, then register the deployed market with [Confirm Deploy](/endpoints/stock-lending/confirm-deploy).

<Warning>
  After deployment, the stock token issuer must authorize both the market and liquidation router on the stock token contract via `addAuthorizedContract`.
