According to the source, a social post on Oct 21, 2025 claims Polymarket launched 15-minute up/down crypto prediction markets powered by Chainlink oracles, but this has not been verified on Polymarket or Chainlink official channels at the time of writing. Source: public social media post dated Oct 21, 2025; Polymarket official website; Chainlink official documentation. Polymarket is a decentralized prediction market platform where users trade on event outcomes, which would be consistent with introducing short-duration markets if officially announced.

Chainlink provides decentralized oracle networks and price feeds that are commonly integrated to settle on-chain markets, which would be the expected mechanism for any short-term price-based contracts.

Before taking positions, traders should confirm an official Polymarket announcement detailing market contract addresses, supported assets, oracle data sources, settlement windows, fee structure, and liquidity incentives, as these determine slippage, execution quality, and risk in short-term markets.

According to @cbetass of @iotex_io, as reported by CoinDesk, the integration of artificial intelligence and real-world data is rapidly gaining momentum, as highlighted during Consensus2025. This trend is seen as bullish for IoTeX and similar blockchain projects focused on AI-driven data automation and verification, potentially driving increased demand for decentralized oracles and on-chain data validation solutions. Traders should monitor IoTeX (IOTX) and AI-linked tokens, as this synergy is expected to boost adoption and trading volumes in the crypto market. (Source: CoinDesk, @cbetass on Twitter, May 21, 2025)
