This dataset contains structured metadata from Polymarket’s Gamma API, enriching prediction markets with thematic,
temporal, and organizational context.

The dataset is composed of three interrelated tables:

• series: Represents high-level themes or recurring structures such as "NFL 2024" or "US Elections".
• events: Groups one or more markets under a specific occurrence within a series, such as a specific game or election.
• markets: The individual prediction markets where trading occurs, linked to their parent event when applicable.

Together, these tables enable analysis at multiple levels — from individual market behavior to trends across events and
entire series. This hierarchy supports richer insights into market structure, coverage, and performance over time.
