Robert Mitchnick, BlackRock’s head of digital assets, is sounding increasingly bullish on Bitcoin’s positioning, pointing to improving sentiment and a meaningful decoupling from traditional equity markets.
The core argument is one Mitchnick has been building for over a year: Bitcoin doesn’t move in lockstep with stocks, and that makes it genuinely useful in a portfolio. During periods of equity market stress, Bitcoin has at times exhibited a correlation to the Nasdaq 100 as low as -0.43. In plain terms, when tech stocks zigged, Bitcoin zagged.
The decoupling thesis gains traction
During volatile stretches across 2025 and into 2026, Bitcoin maintained its value even as major indices like the S&P 500 and Nasdaq declined. Mitchnick has framed Bitcoin as a “non-sovereign and scarce asset,” language designed to resonate with the kind of institutional investors who think in terms of asset class characteristics rather than price charts.
IBIT holders aren’t flinching
The iShares Bitcoin Trust (IBIT) has seen remarkably sticky capital. During periods of market volatility, only about 0.2% of IBIT holdings were redeemed.
That number is striking. ETF investors, particularly institutional ones, are not known for their patience when assets get choppy. A redemption rate that low suggests holders view Bitcoin as a long-term allocation rather than a tactical trade they’ll exit at the first sign of trouble.
The AI capital flow wrinkle
Mitchnick has acknowledged that Bitcoin experienced a roughly 20% price decline that he linked to capital flows rotating toward AI investments. When the hottest narrative in markets is artificial intelligence, some money that might have found its way to crypto gets redirected toward Nvidia and its peers instead.
What this means for institutional adoption
Mitchnick has recommended that investors include modest allocations of 1-2% in multi-asset portfolios. When BlackRock’s digital assets lead talks about Bitcoin as a low-correlation diversifier, he’s speaking directly to the allocation committees at sovereign wealth funds, pension systems, and family offices.
The minimal redemption rates at IBIT suggest early institutional adopters are satisfied with their positions. The risk, of course, is that correlation regimes shift. Bitcoin’s low correlation to equities during recent periods doesn’t guarantee it will remain uncorrelated during the next crisis.
