Connect your exchange
Link your Kalshi or Polymarket account. Your credentials are encrypted with AES-256-GCM and never stored in plain text.

Configure your leverage (up to 4x), margin requirements, and auto-liquidation preferences. Nexum calculates your risk in real time.
Trade with leverage
Place leveraged orders on any market. See your margin health, liquidation prices, and P&L — all from one dashboard.

Frequently asked questions
Important disclosures
Leveraged trading risk
Margin trading amplifies both gains and losses. You can lose more than your initial margin. Leveraged positions carry higher risk than unleveraged trades.
Liquidation risk
If your margin health drops below the maintenance threshold, your positions may be automatically liquidated at a loss. Market volatility can trigger liquidation rapidly.
Not investment advice
