XWIN Research says short interest in US equities has climbed to a record level, while hedge fund gross leverage is close to 293%. In its latest report, the firm argues that the calm seen in headline equity indexes masks a far more defensive market structure underneath, and that shift may matter for Bitcoin.
The report does not frame the rise in short positioning as a simple bearish call. Instead, it describes a market where institutions are still holding large long exposure while adding heavier hedges at the same time. That has created an aggressive grossed-up setup on Wall Street. XWIN notes that both S&P 500 days-to-cover and dollar-based short exposure have reached historic highs.
AI concentration is hiding stress under the index surface
XWIN links the imbalance to capital crowding into large AI-related technology names. Money keeps flowing into a narrow group of market leaders, helping major indexes look stable, while weaker sectors and smaller stocks face rising short pressure. The headline tape looks solid. The internals look far less comfortable.
That distinction matters because it suggests the equity market is not broadly healthy in the way index performance may imply. The report sees this as a sign of mounting structural fragility rather than a straightforward directional bet against stocks as a whole.
Bitcoin is no longer moving in lockstep with the S&P 500
XWIN contrasts the current setup with earlier episodes when Bitcoin traded much more like a risk asset. During the 2020 pandemic shock, BTC sold off alongside equities and did not behave like a classic safe haven. From 2020 to 2022, its price action also tracked the S&P 500 closely for long stretches.
According to the report, that relationship has started to break down since 2025. Even as the S&P 500 has stayed relatively steady in recent periods, Bitcoin has shown more distinct price momentum. XWIN points to strong spot taker CVD and ongoing inflows into spot Bitcoin ETFs as signs that BTC is being driven more by its own liquidity cycle, leverage conditions, and institutional demand.
Why XWIN sees Bitcoin as a secondary liquidity destination
Based on that shift, XWIN describes Bitcoin as moving toward a “hybrid asset class.” In the firm’s view, BTC remains sensitive to macro liquidity, but it is gaining the ability to trade on its own market structure instead of acting only as a high-beta extension of US tech stocks.
The report adds that if macro conditions turn toward Federal Reserve easing, a weaker dollar, and another wave of ETF inflows, Bitcoin may emerge as a “secondary liquidity destination” for global capital looking for growth. That argument rests on a simple contrast: equity indexes may still look resilient, but the internal stress building under US stocks could leave more room for Bitcoin to trade on its own path.
