The expansion of Polymarket highlights the growing role of blockchain oracles like Pyth Network and Chainlink. These systems provide real-world data — including asset prices and economic indicators — directly to blockchain applications, enabling automated and transparent settlement of contracts.

Oracles are increasingly being used beyond crypto, including in financial infrastructure and government data systems. Their integration allows platforms to connect with traditional markets, supporting use cases such as tokenized equities, derivatives, and prediction-based trading.
