Gemini's New Taxonomy Revolutionizes Access to Sports Prediction Markets for Developers

#How is Gemini Enhancing Developer Access to Prediction Markets?

Gemini has taken a significant step forward by simplifying the process for developers to engage with its prediction markets. By introducing a standardized sports market taxonomy through the Predictions API, Gemini provides a structured classification system that categorizes sporting events by sport type, market family, and participant details.

The main benefit of this release is the ability for developers to access clear and structured data instead of having to decode information by interpreting titles or tickers. This streamlined approach enhances the user experience and enables better decision-making for applications built on Gemini’s platform.

#What are the Key Features of the Sports Market Taxonomy?

Central to this new feature is the sportsMarket object, a standardized label assigned to each sports prediction event listed on Gemini. This object comprises essential fields like sport, type, subject, and scope, along with an optional metric field for fine-tuning data filtering. These fields are foundational for developers focused on creating trading tools, data analytics dashboards, or fully automated trading strategies utilizing Gemini's markets.

The classifications incorporated within the market family encompass a broad range of categories recognized by sports bettors, including moneyline, spread, totals, props, and futures. The coverage is extensive, addressing major sports like baseball, soccer, American football, and cricket.

Developers can now filter markets using specific parameters such as sport=american_football, sports_market_type=prop, and sports_market_metric=passing_yards. This targeted filtering marks a substantial advancement compared to the previous dependency on title parsing, enabling developers to pinpoint relevant market data more effectively.

#How Does the Taxonomy Improve Event Discovery?

Rather than classifying individual contracts, this new taxonomy operates at the event level, concentrating on the game or matchup itself. Consequently, users who seek live contract data must still access the List Events endpoint for comprehensive listings. However, this taxonomy acts as an efficient tool for locating pertinent events quickly.

#What Underpins This Development from a Regulatory Perspective?

Gemini Titan, the exchange's subsidiary, functions as a CFTC-designated Designated Contract Market. This designation, granted in December 2025, authorizes the exchange to provide yes/no event contracts linked to real-world outcomes for US customers. Gemini Predictions began trading in early 2026, following a nationwide expansion of the platform's offerings.

#Why Should Developers and Traders Take Notice?

This new infrastructure allows market makers to automate pricing across similar event types while enabling analytics firms to gather data consistently. Trading bots gain the ability to filter for specific market conditions without needing customized parsing for each new listing. It is worth noting that this release does not involve any crypto tokens, focusing instead on strictly CFTC-regulated event contracts denominated in US dollars.

However, it is vital to acknowledge the regulatory risks involved. The CFTC's stance towards event contracts may evolve, and the distinction between prediction markets and sports betting is still legally uncertain in various jurisdictions. Some state gaming commissions have not universally accepted that a federally regulated DCM may offer services resembling sports betting without a state gaming license.

For traders developing strategies using this infrastructure, it is critical to verify market availability through the API's List Events endpoint. While the taxonomy outlines a robust classification system, it does not guarantee the availability of active contracts for every possible event at all times.
