Grid, a data company in Berlin, has joined Sportstensor to provide verified esports data for prediction markets. As Sportstensor’s official esports data oracle, Grid will supply live, accurate match data sourced directly from game servers.

The deal covers major titles like Counter-Strike 2, Dota 2, League of Legends, and Valorant, using official data from Grid’s publisher and tournament partners. This partnership strengthens the accuracy and trust of Polymarket’s esports prediction markets by ensuring all outcomes rely on verified, rights-compliant information.

How It Works: Data Meets Blockchain

In decentralised platforms like Polymarket, prediction markets allow users to trade on the outcomes of real-world events, such as sports matches, elections, or in this case, esports games. However, for these markets to function properly, they need reliable and tamper-proof data to confirm the results of each event.

That’s where data oracles come in. A data oracle acts as a bridge between real-world data and blockchain-based systems, feeding accurate match results into smart contracts. By partnering with Grid, Sportstensor ensures that the results and stats used to settle esports markets are authentic, verified, and transparent.

Grid’s technology captures server-level data. That means it comes directly from the game’s servers rather than third-party sources. This helps prevent manipulation, improves fairness, and allows Polymarket to offer new and creative types of esports prediction markets. For example, users could even predict the total number of chickens eliminated in a Counter-Strike 2 tournament, with results automatically verified on the blockchain.

Building Trust and Transparency in Esports Predictions

Grid’s Vice President of Growth, Dominika Szot, said the partnership is a major step forward for esports and prediction markets. She noted that prediction markets are growing fast and that esports, being digital by nature, fits perfectly into this space.

Szot added that integrity is vital for fairness and trust. She said using official data makes predictions clear, secure, and more fun for users.

Leo Chan, Co-Founder and CEO of Sportstensor, also stressed the importance of verified data for user trust. He said partnering with Grid ensures esports markets are settled with accurate data straight from the source, allowing Sportstensor to build richer and more engaging markets for Polymarket users.

A Step Toward a Data-Driven Digital Future

The partnership establishes Grid’s position as a leading provider of official esports data and expands its role in shaping how verified gaming information is used in new digital spaces.

By connecting accurate esports data with decentralised finance systems, Grid and Sportstensor are helping to build a more transparent, data-driven digital economy. Their collaboration could open doors for even more innovative prediction markets in the future, where fans can not only watch their favorite games but also engage with them in entirely new, trusted ways.
