How We Fund This Site

Expected Value is a free educational resource covering probability, decision-making, and quantitative thinking. To keep this site running and our content free, we participate in affiliate programmes with companies whose products and services we genuinely believe are useful to our readers.

When you click on certain links on our site and make a purchase or sign up for a service, we may earn a commission at no extra cost to you. These commissions help us cover hosting, research and content creation costs.

Our Editorial Standards

Our editorial content is never influenced by affiliate partnerships. We recommend products and services based on our own analysis and research. If a product doesn't meet our standards, we won't recommend it — regardless of the commission it might offer.

We apply the same rigorous, evidence-based thinking to our recommendations that we advocate in our content. Every recommendation is evaluated on its merits.

What This Means for You

• No extra cost — Using our links never increases the price you pay. In many cases, we can offer exclusive deals through our partnerships.
• Honest analysis — Our reviews and comparisons reflect our genuine assessment, including both strengths and weaknesses.
• Full transparency — Pages containing affiliate links are clearly identified.

Types of Partnerships

We may earn commissions from:

• Betting and trading platforms
• Educational courses and tools
• Books and learning resources
• Financial analysis software

Compliance

This disclosure complies with the Federal Trade Commission (FTC) guidelines on endorsements and the UK Advertising Standards Authority (ASA) requirements for affiliate marketing.
