Bitcoin may be moving more closely with U.S. equities in the short run, but NYDIG argues that the market is overstating how deep that relationship really goes. In research led by Head of Research Greg Cipolaro, the firm said U.S. equity factors explain only about 25% of Bitcoin’s price fluctuations, even as short-term correlations with major U.S. stock indices climbed to roughly 0.5 on March 8, 2026. The bigger takeaway from NYDIG’s work is that most of Bitcoin’s volatility still comes from forces inside crypto itself, not from the same drivers that move large-cap technology stocks.

That distinction matters because Bitcoin is increasingly being pulled into macro portfolios at the exact moment investors are debating what it actually is. If it behaves too much like a high-beta tech asset, its diversification case weakens. If its core drivers remain separate, temporary correlation spikes may look more like noise than a permanent shift.

Correlation has risen, but NYDIG says the market should not overread it

NYDIG documented a clear rise in Bitcoin’s measured correlation with the S&P 500, the Nasdaq 100, and even sector-linked products such as the iShares Expanded Tech-Software ETF (IGV). On the surface, that kind of move can make Bitcoin look increasingly tied to the same risk appetite that drives growth equities. But NYDIG’s central argument is that a higher short-term correlation does not automatically mean Bitcoin has become structurally linked to tech stocks.

Cipolaro framed the issue in macro terms rather than in fundamental ones. He said the current price linkage reflects broader liquidity conditions and general risk appetite, not a deep economic connection between Bitcoin and the earnings, margins, and innovation cycles that support technology-company valuations. In other words, Bitcoin and tech can move together for a while without being driven by the same core engine.

That matters because markets often treat correlation as explanation when, in reality, it is sometimes only a description of what happened over a short window. NYDIG’s position is that the recent rise in co-movement says more about the macro environment than about Bitcoin’s identity as an asset.

NYDIG says most of Bitcoin’s movement still comes from crypto-native forces

The research argues that the remaining 75% of Bitcoin’s volatility is better explained by factors that are specific to digital assets. Those include fund inflows into Bitcoin-related products, changes in derivatives positioning and leverage, shifts in network adoption and on-chain activity, and regulatory developments that affect access, custody, and investor participation. That framework keeps Bitcoin in its own category, even when it briefly trades in sync with broader risk assets.

This is where NYDIG draws the sharpest line between Bitcoin and equities. Technology shares are ultimately grounded in company-specific cash flows, valuation multiples, and business execution. Bitcoin, by contrast, is still much more sensitive to flows, positioning, and policy signals that are unique to the crypto market. That does not make it immune to macro conditions, but it does mean its longer-term price behavior cannot be explained simply by watching the Nasdaq.

NYDIG also noted that both Bitcoin and growth-oriented equities can behave like liquidity-sensitive duration assets. When liquidity expands and investors become more comfortable taking risk, both can rise together. When liquidity tightens, both can come under pressure at the same time. But sharing a vulnerability to liquidity does not erase the fact that each asset still responds to a different set of deeper market mechanics.

The portfolio question is not whether Bitcoin correlates, but why

For allocators, the implication is more nuanced than a simple “Bitcoin is or isn’t a diversifier.” NYDIG’s conclusion suggests that short-term correlation spikes are real and should not be ignored, especially during macro-driven market phases. At the same time, the firm is effectively arguing that Bitcoin still retains diversification value because its long-run drivers remain distinct from those of traditional equities.

That means portfolio managers may need to think about Bitcoin in two layers. In the short term, it can behave like a liquidity-sensitive risk asset, especially when macro themes such as AI enthusiasm or the prospect of monetary easing boost appetite across multiple markets at once. In the longer term, though, Bitcoin’s returns are still more likely to be shaped by product flows, derivatives leverage, regulatory access, and adoption trends than by anything resembling a corporate earnings cycle.

Practically, NYDIG’s work suggests that managers should not rely on equity-market behavior alone to understand crypto risk. Watching fund flows into Bitcoin products, changes in futures positioning, and on-chain adoption data may tell them more about near-term market stress or upside potential than simply watching the next move in the S&P 500. The message is not that Bitcoin is disconnected from macro, but that macro is only one layer of a much more crypto-specific pricing structure.

If global liquidity conditions ease, Bitcoin may continue to move more closely with growth assets for a time. If liquidity tightens, the same temporary alignment could produce simultaneous declines. But in either case, NYDIG’s point remains the same: Bitcoin should still be treated as an asset class with its own internal market logic, not as a dressed-up technology trade.
