Polymarket is embroiled in a dispute over the resolution of a prediction market, centered on the interpretation of rules and data sources. The market's resolution source is defined as the most liquid price source available. The "NO" side argues that CoinMarketCap's liquidity score favors Coinbase, and even using Upbit, the value converted to USDC remains below $4 billion. Polymarket later noted that at the resolution time, Coinbase was the most liquid source, implying support for this view. Conversely, the "YES" side contends that Upbit's higher trading volume should take precedence, and since the rules do not specify a price type, aggregated prices from any exchange exceed $4 billion. They argue that the fully diluted valuation (FDV) should be calculated in USD, independent of USDC/USDT. This debate highlights the complexities in prediction market rule interpretation and the potential for strategic marketing opportunities.
