Bitcoin down 3%, S&P 500 up 16%: why crypto’s biggest bull case failed?
Bitcoin’s 3% decline in 2025 while the S&P 500 soared 16% marks a historic divergence, the first time since 2014 that the world’s largest cryptocurrency has underperformed equities during a substantial market rally.
This decoupling highlights a major crack in the institutional-adoption story that fueled so much crypto optimism going into 2025.
Spot Bitcoin ETF approvals, clearer rules under the Trump administration, and expectations of a dovish Fed were all supposed to open the floodgates for institutional money, but that surge never truly arrived.
Instead, mega-cap tech stocks and AI-driven equities captured nearly all the flows, leaving Bitcoin marooned in a consolidation pattern that has tested the patience of even hardened crypto believers.
The broken thesis: Why institutional money went elsewhere
When the SEC approved spot Bitcoin ETFs in January 2024, crypto evangelists proclaimed a watershed moment.
BlackRock’s IBIT ETF alone pulled in $50 billion within months, and Bitcoin surged on expectations that endowments, pension funds, and asset managers would treat digital assets as core portfolio holdings.
By Q1 2025, institutional Bitcoin ETF holdings hit $21.2 billion: real, meaningful allocation from serious money.
But here’s what actually happened: institutional capital flowed into familiar territory. Nvidia gained 32% this year. Meta rallied on AI enthusiasm.
Magnificent Seven dominance crowded out alternative assets.
Bitcoin’s short-squeeze mentality and high volatility, traits that appeal to retail traders, proved less attractive to fiduciaries building long-term portfolios.
Goldman Sachs observed the brutal asymmetry: Bitcoin sees smaller gains when equities rally but steeper losses when they fall, making it a poor portfolio complement to stocks.
The Trump administration’s pro-crypto rhetoric, which many expected would unlock institutional tailwinds, hasn’t materialized into sustained buying pressure.
Regulatory clarity is nice, but it doesn’t override capital allocation decisions.
When the S&P 500 offers 16% returns powered by tangible AI productivity gains and earnings growth, fiduciaries ask themselves: why hold a volatile, macroeconomically sensitive asset that generates no cash flow?
Bitcoin as a macro asset, not a growth play
Recent analysis from Nansen and other on-chain researchers reveals a hard truth: Bitcoin no longer trades on its four-year halving cycle narrative.
Instead, it behaves like a macro asset embedded in institutional portfolios, responding primarily to liquidity conditions, dollar dynamics, and interest rate expectations.
This explains the 2025 puzzle. Equity investors enjoyed a “risk-on” environment anchored to AI productivity and soft-landing scenarios.
Bitcoin traders faced a liquidity squeeze, exacerbated by the US government shutdown and tightening funding conditions, that triggered long liquidations and profit-taking from early holders.
A 25% pullback from October highs created a technical “death cross,” a bearish signal traditionally associated with capitulation lows. But the rebound failed.
Bitcoin’s institutional adoption story assumed that regulatory clarity and ETF access would drive sustained buying.
Instead, 2025 proved that institutions allocate capital based on return expectations and portfolio fit, not ideology.
Bitcoin’s lack of cash-flow generation, structural sensitivity to macro liquidity, and inability to outperform equities during a risk-on cycle have exposed a gap between the bull case and reality.
Until Bitcoin demonstrates either genuine economic use cases generating revenue or clear superiority as a macro hedge, expect continued underperformance relative to equity upside.
