Priorbook · Terms of Service
Last updated: August 2026
Priorbook’s composite fair-value model — including its methodology, layer structure, exact weightings, and underlying algorithms — is the proprietary and confidential property of Priorbook and its founder. Nothing on this site grants you a license to reproduce, decompile, reverse-engineer, or commercially exploit the model, its outputs, or the site’s underlying code and design. All content, branding, and software on this site are protected by applicable copyright and intellectual-property law.
Priorbook is a research and data tool. Nothing on this site is investment, financial, legal, or trading advice, and nothing constitutes a recommendation to buy, sell, or hold any contract on Kalshi, Polymarket, or any other venue. Any ratings, grades, or fair-value estimates Priorbook produces — now or in the future — are for informational purposes only. You are solely responsible for your own trading decisions.
Priorbook does not execute trades, hold funds, or act as a broker or exchange. All trading happens on the third-party venue of your choice, subject to that venue’s own terms.
Priorbook is provided “as is.” Market data is sourced from third parties and may be delayed, incomplete, or inaccurate. We make no guarantee of uptime, accuracy, or fitness for a particular purpose.
To the maximum extent permitted by law, Priorbook and its founder are not liable for any losses, financial or otherwise, arising from your use of this site or reliance on any information it provides.
We may update these terms as the product evolves. Continued use of the site after changes means you accept the updated terms.
