You might have heard about Polymarket already, or maybe Kalshi or something else, but if you want to really understand this field, we invite you to join us for an evening exploring one of the most intellectually honest tools in forecasting - prediction markets.
Whether you're new to the concept or already deep in the space, this event is designed to give you real value and a deeper understanding of the concepts and the different solutions and approaches in the field.
We'll cover the mechanics: how prediction markets aggregate information, why they tend to outperform traditional forecasting, and what's actually being built on-chain today. From there, we'll move into the regulatory reality - what's permitted, what's contested, and how the legal landscape is shaping (and limiting) what builders can ship.
The night closes with an open conversation featuring practitioners actively working in the space - a chance to ask the hard questions directly to the people navigating these challenges firsthand.
***
What to expect:
- A grounded introduction to how prediction markets function and why they matter
- A clear-eyed look at the regulatory and legal environment
- Live Q&A and open discussion with builders and contributors in the space
***
- This event is a part of a special collaboration between Blockchain B7 Foundation and the Web3 Devs Underground Community - where developers, researchers, and founders meet to build, learn, and connect.
