About

Built by traders and quants who wanted to see more.

Prediction markets became real markets. The tools for reading them didn't keep up. Harpoon is the terminal we wanted: built for event contracts from the first line of code, and fast enough to keep up with the book.

What we believe

• See everything. Every contract, every trade, the depth of the book, not a summary of them.
• As fast as your own machine. Drawn natively on your GPU, in the browser or on the desktop.
• Never rewritten. The history you look back on is the market as it happened.
• Honest about where it stands. The roadmap says what works today, and promises no dates.

Who we are

Harpoon Terminal is a small, independent team. We are not an exchange or a broker, and we are not affiliated with any market whose data Harpoon shows.
