BLACKROCK RE-UNDERWRITES BITCOIN — 50% DROP IS POSITIONING NOT THESIS, 1-2% ALLOCATION HOLDS
BlackRock published Re-Underwriting Bitcoin this week. The world’s largest asset manager laid out why Bitcoin’s 50%-plus decline from its $126,300 October 2025 high reflects a shakeout in positioning, not a breakdown in the underlying investment thesis. The recommendation stands: a 1-2% Bitcoin allocation funded by trimming equities in a classic 60/40 stock-and-bond portfolio. When the world’s largest asset manager writes ‘Re-Underwriting Bitcoin’ and concludes ‘keep buying,’ that’s the Capitalist thesis validated at scale.
The mechanics BlackRock names. Bitcoin futures open interest reached extreme speculative levels heading into October 2025, exceeding $90 billion. A liquidation cascade on October 10 wiped out roughly $20 billion of that open interest in a single day. Further waves followed in February and June. This is not a fundamental thesis break. It is leverage getting cleared out of a market that got overheated on positioning.
The AI rotation context. BlackRock notes that AI-themed funds pulled in more than $46 billion in the months after Bitcoin’s October top. That’s a rotation of institutional capital toward a competing narrative — not because Bitcoin’s case broke, but because AI briefly became the higher-conviction discretionary bet for a class of allocators. That flow will normalize; Bitcoin’s core case (monetary alternative, portfolio diversifier) doesn’t change with the AI cycle.
The Capitalist read. This is the argument the four-character framework predicted BlackRock would eventually make in writing. Bitcoin as digital capital, integrated into every portfolio, sized against equity exposure in a classic asset-allocation framework. Not as a speculation. Not as a hedge-only. As a monetary alternative with portfolio-diversification properties that require a formal allocation. BlackRock, of all firms, publishing ‘Re-Underwriting Bitcoin’ with a 1-2% recommendation is what Capitalist adoption looks like when it stops being a story and starts being a house view.
The selling pressure context. U.S. spot Bitcoin ETPs saw roughly $5 billion in aggregate outflows during the drawdown. Strategy sold a small amount of BTC in June and introduced a capital-allocation framework that permits further sales — a shift for a company that had built its identity around never selling. IBIT itself absorbed a $1.3B block trade during the period. Institutional flow got concentrated and lumpy, but the aggregate case held. And on the other side, IBIT is now pulling flow again (see today’s $143M inflow story on the board).
Bitcoin’s dual personality, per BlackRock. The report characterizes periods when Bitcoin correlates with risk assets as episodic rather than structural. That distinction matters: BlackRock is telling institutional allocators that the correlation-with-equities behavior operators saw during the October-February drawdown was a leverage-clearing event, not a permanent shift in what Bitcoin is for. In other words: keep the allocation. The next monetary shock returns Bitcoin to hedge behavior. Sound-money case intact.
What operators should notice. Every asset manager that publishes a ‘Re-Underwriting X’ report on a battered asset is either capitulating or reinforcing. BlackRock reinforced. The largest allocator on earth just told its client base that the correction is a buying opportunity within the recommended sizing. That is Capitalist-tier catalyst, and the ETF flow data ($951M into US spot BTC ETFs in August so far) is the receipt.

50% drop is positioning.
The thesis holds.
The cap is still twenty-one million.
