Bitcoin vs Nasdaq: a correlation that keeps tightening

Why this comparison matters

For years Bitcoin was sold as an asset that moves on its own logic, uncorrelated with stocks. The data tells a different story. Since the 2020 liquidity surge, Bitcoin and the Nasdaq 100 have drifted into the same orbit, and the question for any allocator is no longer whether they are linked but how tightly, and when the link breaks.

What Bitcoin is

Bitcoin is a fixed-supply digital asset with no earnings, no dividend and no central issuer. Its price is set entirely by the balance of buyers and sellers, which makes it acutely sensitive to global liquidity and risk appetite. Annualised volatility since 2015 has run near 54%, against roughly 13% for the S&P 500, according to data compiled by Winthrop Wealth.

What the Nasdaq 100 is

The Nasdaq 100 tracks the 100 largest non-financial companies on the Nasdaq exchange, weighted by market value. It is intensely concentrated: the so-called Magnificent Seven reached about 43.6% of the index by July 2025, and the top ten holdings represented roughly 51% in January 2025, per Nasdaq and YCharts data. Unlike Bitcoin, it is a claim on real corporate earnings that grow or shrink with the economy.

The key differences

Underlying claim. The Nasdaq 100 is a portfolio of earnings streams; valuation rests on discounted future cash flows. Bitcoin has no cash flow, so there is no fundamental anchor — its value is whatever the marginal buyer will pay, driven by liquidity rather than profits.

Correlation and beta. Here lies the angle. Bitcoin and the Nasdaq are not opposing assets; for most of the past decade Bitcoin behaved as a high-beta version of the index. The IMF found the daily-returns correlation between Bitcoin and the S&P 500 rose from 0.01 in 2017-19 to 0.36 in 2020-21. Rolling correlations with the Nasdaq 100 peaked near 0.87 in mid-2024 after spot-ETF approval, according to academic and S&P Global research, with Bitcoin amplifying index moves through a roughly three-to-four-times volatility multiple.

Behaviour at the extremes. The tight link is regime-dependent, not permanent. When crypto leverage builds and then liquidates, Bitcoin can fall while the Nasdaq holds: in early December 2025 the 20-day correlation turned negative, near -0.43, as Bitcoin dropped well over 30% from its October peak while the Nasdaq 100 sat about 2% below record highs, per CoinDesk. By March 2026 S&P Global put recent BTC-Nasdaq correlation near 0.3 — still positive, but far from the 2024 peak.

How they behave across regimes

The pivot is liquidity and the cost of capital. In abundant-liquidity, risk-on conditions — 2020-21, when the Fed held rates near zero — both assets surged together and Bitcoin ran ahead as the higher-beta expression of the same trade. In the 2022 tightening, with real yields swinging from deeply negative to positive, both fell, and Bitcoin fell harder. The third regime is crypto-idiosyncratic: when forced liquidations hit a leveraged crypto market, as in the October-December 2025 unwind, Bitcoin can decouple sharply from a Nasdaq that barely flinches. The link tightens with shared macro drivers and snaps when crypto-specific leverage dominates. Crypto-specific leverage taking over is one of the structural drivers of crypto cycle amplitude.

Bitcoin is the Nasdaq stripped of its cash flows: it amplifies the same liquidity tide, until its own leverage pulls it under.

The common confusion

The widespread belief is that Bitcoin is “digital gold” — an uncorrelated store of value that diversifies an equity portfolio. The data since 2020 has not supported that framing. Bitcoin has correlated more with the Nasdaq than with gold, and its correlation with traditional risk assets has consistently exceeded its correlation with bullion. The accurate description is closer to a liquidity-sensitive risk asset than a safe haven.

Frequently asked questions

How correlated are Bitcoin and the Nasdaq?

It depends on the regime. The daily-returns correlation between Bitcoin and US equities was close to zero in 2017-19, then rose to about 0.36 in 2020-21 as both responded to easy liquidity, according to the IMF. Rolling correlations with the Nasdaq 100 peaked near 0.87 in mid-2024. They are not fixed: during the late-2025 crypto deleveraging the 20-day correlation briefly turned negative, near -0.43, before settling back to roughly 0.3 in early 2026.

Why does Bitcoin sometimes move more than the Nasdaq?

Because Bitcoin carries no cash-flow anchor and has historically run three to four times as volatile as broad equity indices, it tends to amplify the moves of the assets it correlates with. When the same liquidity and risk-appetite drivers push the Nasdaq higher, Bitcoin often rises further; when those drivers reverse, it can fall harder. The relationship resembles a high-beta tech position rather than a separate asset class. Related material: the comparison pages gathered together.

Does Bitcoin still work as a portfolio diversifier against tech stocks?

The historical record since 2020 documents limited diversification when it is most wanted. Bitcoin has correlated more closely with the Nasdaq than with gold, and that co-movement has tended to intensify during risk-off episodes driven by shared macro shocks. The exception is crypto-specific stress, when Bitcoin can decouple downward independently of equities — a divergence that is descriptive of past episodes, not a forward signal.
