What is Adjacent?
Adjacent turns individual event contracts into broader research products: indices, reference rates, dashboards and market commentary. It is useful when a single contract is too narrow for the question you are researching—for example, when you want a thematic view or a benchmark to compare with your own basket. Its news product explains developments through market probabilities and changes in activity.
