BlackRock's SPX6900, a satirical meme coin, has surged over 80,900,000% since its 2023 debut, becoming the third-largest holding in BlackRock's portfolio after Bitcoin and Ethereum. The coin, which parodies the S&P 500, hit an all-time high of $2.27 on July 28, 2025, making it the top performer in the past 90 days. Despite a recent 5.89% decline, SPX6900 remains up over 10% in the last week, currently trading at $2.13. With a market cap of $1.98 billion and a daily trading volume of $94.28 million, it ranks 52nd globally by market capitalization. Technical indicators show a bullish trend, though the RSI suggests overbought conditions, with potential support at $1.93 if it falls below the $2.05 pivot.
