Terms of Service

Last updated: June 12, 2026

Welcome to The Closing Line (“the Site”), operated at www.theclosingline.net. By accessing or using the Site, you agree to these Terms of Service. If you do not agree, please do not use the Site.

1. The Service

The Closing Line publishes articles, analysis, and calculators related to prediction markets (including Kalshi) and sports betting. Access to most content requires a free account. We may add, change, or remove features at any time.

2. Not Financial, Investment, Tax, or Legal Advice

Everything on this Site is for informational and educational purposes only. Nothing published here — articles, trade ideas, calculators, tools, estimates, or any other content — constitutes financial, investment, tax, or legal advice, or a recommendation to buy or sell any contract or place any wager. Trading event contracts and sports betting involve substantial risk of loss. Never risk money you cannot afford to lose. Always do your own research and consult qualified professionals before making financial decisions.

3. Eligibility

You must be at least 18 years old to use the Site. You are responsible for ensuring that any trading or betting activity you engage in is legal in your jurisdiction.

4. Accounts

• You are responsible for safeguarding your account credentials.
• You agree to provide a valid email address.
• We may suspend or terminate accounts that abuse the Site, attempt to scrape content, or violate these terms.
• You may delete your account at any time from your profile page.

5. Intellectual Property

All content on the Site — articles, graphics, tools, and code — is owned by The Closing Line unless otherwise noted. You may share links to our content freely. You may not republish, scrape, or redistribute substantial portions of our content without permission.

6. Calculators & Tools

Our calculators (fee, odds, arbitrage, Kelly, expected value, tax, and others) provide estimates based on simplified models and publicly available formulas. They may contain errors, may not reflect current exchange fee schedules or tax law, and should never be the sole basis for any financial decision. Verify all numbers independently.

7. Third-Party Services & Links

The Site may contain links to third-party websites (including Kalshi, sportsbooks, and Substack) and displays advertisements served by Google AdSense. We are not responsible for the content, accuracy, or practices of third parties. We are not affiliated with, endorsed by, or sponsored by Kalshi, Inc.

8. Disclaimer of Warranties

The Site is provided “as is” and “as available” without warranties of any kind, express or implied, including accuracy, completeness, fitness for a particular purpose, or uninterrupted availability.

9. Limitation of Liability

To the maximum extent permitted by law, The Closing Line and its operators shall not be liable for any direct, indirect, incidental, consequential, or special damages — including trading or betting losses — arising from your use of the Site or reliance on its content.

10. Changes to These Terms

We may update these Terms from time to time. Continued use of the Site after changes are posted constitutes acceptance of the revised Terms.
