According to Moonshot, SPX6900 significantly outperformed the S&P500 during May 2025, as referenced by the reported data (source: Moonshot on Twitter, June 4, 2025). This strong performance signals increased risk appetite in U.S. equity markets, which historically correlates with bullish momentum in major cryptocurrencies like Bitcoin and Ethereum. Crypto traders should monitor SPX6900 and related indices for continued inflows, as these can indicate a favorable environment for digital asset rallies, especially in sectors linked to tech and AI stocks that often drive both equity and crypto markets.
