The S&P 500 has gained roughly $2.1 trillion in market value this month, an amount comparable to the size of the entire crypto market’s capitalization. Yet bitcoin has barely advanced, highlighting a growing disconnect between traditional markets and digital assets.
U.S. stocks have regained momentum, while bitcoin has remained largely stagnant, continuing a pattern seen throughout the year. The reasons behind bitcoin’s underperformance are more complex than simply a lack of investor appetite for risk.
The S&P 500 has climbed 3.12% in August, adding about $2.1 trillion in market capitalization and reaching a record valuation of $70.5 trillion as the index trades near 7,723 points. The Nasdaq 100 and Dow Jones Industrial Average have also moved higher, reflecting strong confidence across equity markets.
Bitcoin, meanwhile, has struggled to follow the rally. Despite developing a stronger correlation with stocks after the 2020 pandemic-era market crash, BTC has gained only around 2% this month and remains near $64,600, where it has been trading within a narrow range for weeks.
Analysts say one major reason for bitcoin’s muted performance is that the current stock market rally is being driven by specific sectors rather than broad economic optimism. Artificial intelligence and semiconductor stocks have led the advance, areas where bitcoin has limited direct exposure.
Adam Haeems, head of asset management at Tesseract Group, said the equity rally has been concentrated in AI and chip companies, which does not necessarily translate into stronger bitcoin demand.
Although some macro developments are positive for risk assets, such as declining oil prices and expectations of normalized shipping activity through the Strait of Hormuz, their impact has favored equities more quickly than crypto markets.
Haeems explained that lower oil prices can immediately improve corporate profitability, while bitcoin benefits only indirectly through potential changes in inflation expectations and Federal Reserve policy. With uncertainty still surrounding the Fed’s September outlook, the effect on crypto has been slower to materialize.
Paul Howard, senior director at market maker Wincent, echoed the view that the current stock rally is not automatically benefiting digital assets. He noted that the market’s focus on AI and mega-cap stocks has not translated into meaningful crypto inflows.
Howard added that bitcoin’s previous gains were strongly supported by ETF demand over the past two years, but that momentum has weakened as the crypto market searches for new drivers. He expects regulatory progress and continued stablecoin adoption to potentially provide fresh catalysts later in the year.
Crypto market pressures weigh on bitcoin
Bitcoin is also facing several industry-specific challenges that have limited upside momentum. Recent concerns include the $120 million Coldcard wallet exploit, uncertainty surrounding the Clarity Act, and reports that Strategy has been selling portions of its BTC holdings.
Haeems said these developments have hurt sentiment but have not yet resulted in a broader market crisis or forced liquidation event.
He also pointed to higher bond yields as a challenge for crypto, as investors are increasingly attracted to traditional yield opportunities. Stablecoin supply has declined as capital remains outside digital assets.
According to Haeems, USDT supply has fallen from roughly $190 billion in April to $183 billion, while USDC has dropped from about $79.5 billion to $72 billion. With real Treasury yields at their highest levels since 2008, investors have fewer incentives to deploy capital into crypto markets.
Halving cycle expectations and ETF demand concerns
Bitcoin’s traditional four-year halving cycle is another factor influencing market behavior.
Markus Thielen, founder of 10x Research, said many traders are delaying new positions because they expect a potential cycle bottom around October based on historical trends. This cautious approach has reduced buying pressure despite strength in U.S. equities.
Thielen said bitcoin traders have become increasingly focused on the idea that the market may not bottom until later in the year, causing many investors to remain on the sidelines.
He also argued that traders may be overlooking a bullish development: bitcoin has held up despite a restrictive Federal Reserve environment.
According to Thielen, the possibility of a softer Fed stance and the chance that the cycle low has already occurred could create upside potential that the market is currently ignoring.
Other analysts believe inconsistent bitcoin ETF flows are contributing to weak price performance. U.S.-listed spot bitcoin ETFs recently recorded $61.53 million in outflows, ending a modest three-week inflow streak, according to SoSoValue data. Although ETF products attracted $626 million this week, analysts say sustained inflows are needed to confirm renewed institutional demand.
Vikram Subburaj, CEO of FIU-registered crypto platform Giottus.com, said multiple days of consistent ETF inflows would be necessary before confirming a stronger institutional recovery. He identified bitcoin support around $63,000-$63,400 and resistance between $64,500 and $66,000.
Market maker Wintermute suggested that some ETF activity may not represent direct bullish positioning, but instead could be driven by arbitrage strategies.
The firm noted that ETF buying has not translated into significant price movement, suggesting spot market demand remains limited. Instead, investors have rotated into individual crypto assets, with ZEC gaining 10.9% over the week and HYPE rising 5% during a weak market environment.
Wintermute said broader crypto momentum may return only after bitcoin volatility declines and BTC establishes a clearer directional trend.
