Woofun AI reports that US spot Bitcoin ETFs recorded a cumulative net outflow of approximately $6 billion over the past six weeks, establishing the longest consecutive weekly loss streak since their 2024 launch. BlackRock's flagship fund, IBIT, absorbed the brunt of this exodus, shedding $1.3 billion in a single week and accounting for over 70% of the industry's total outflows during that period. While institutional investors executing sales through brokerage accounts drove these figures, on-chain metrics indicate that long-term holders possessing BTC for more than 155 days remain stable, still controlling around 83% of the circulating supply.

The deeper driver is a macroeconomic shift where the core PCE index returned to 4.1%, prompting the Federal Reserve to adopt a tighter policy stance and increasing the probability of a rate hike.

Concurrently, the AI infrastructure sector attracted $700 billion in investment within a year, while high-profile IPOs like SpaceX's drew significant capital away from speculative assets. As traders reduced positions en masse, BTC, classified as a high-beta risky asset, faced immediate and severe selling pressure, causing realized losses to surge by 78% month-on-month.

Woofun AI data shows that most sellers exited at prices between $55,000 and $68,000 to cap losses, yet the outflow velocity has decelerated sharply. The daily net outflow dropped from $1.72 billion in the first week of June to just $226.8 million by mid-month, representing a reduction of nearly 90%. Despite this slowdown, the structural vulnerability persists because the sheer size of IBIT means any redemption from it alone creates substantial market pressure; on one specific day, the entire market outflow of $444.5 million originated solely from IBIT.

As spot supply contracts and on-chain activity wanes, new capital inflows have stalled, leaving buyers increasingly scarce. If IBIT outflows continue to moderate and BTC price recovers above $60,000, this episode may represent a necessary reset of market dynamics rather than a collapse. Conversely, should IBIT face further large-scale redemptions pushing the price below $58,000, non-ETF spot buyers will be forced to absorb the full weight of institutional exits. This scenario marks a critical divergence point for the asset's liquidity structure.
