Bitcoin spot ETFs have experienced nine consecutive days of net outflows totaling $2.8 billion through May 28, the largest outflow streak in 2026. The worst single-day outflow of $733.43 million occurred on May 28, driven primarily by BlackRock's IBIT. Since mid-May, weekly outflows have accelerated from $1 billion to $1.26 billion and now $1.3 billion, pushing year-to-date flows negative, according to Galaxy Research. Analysts describe this as a 'real directional recalibration' rather than profit-taking. Factors include investor rotation to AI-driven tech stocks, which have surged amid the AI boom and geopolitical tensions such as the U.S.-Iran war. The S&P 500 hit a new all-time high of 7,568, while Bitcoin failed to break $82,000 and fell to a six-week low below $74,000. On-chain data from CryptoQuant shows whale balances (1K-10K BTC) contracting at the fastest pace since 2022, and long-term holder supply hitting a record 15.8 million BTC, interpreted as a lack of new buyers rather than accumulation. Short-term holder supply dropped by 2.2 million BTC since December, partly due to aging into long-term holdings. Prediction markets show bearish sentiment, with only a 63% chance Bitcoin reaches $84,000, down from 92% on May 6.
