Theta Labs is the home of options on prediction markets. Buy cash-settled call options on a market’s probability — Yes Calls and No Calls — to get leveraged exposure with your risk strictly capped at the premium you pay. Alongside options, you can trade spot YES/NO shares on Polymarket markets from the same account and balance. Everything runs on a single pUSD balance: deposit USDC on Polygon and it converts automatically — no external wallet, no manual transfers between platforms.
Options on Theta Labs are real-money trading. The premium you pay is the most you can lose on a contract you buy, but losses are real. Trade responsibly.
