The S&P 500 has added $2.1 trillion in market value this month, driven by an AI-led rally, while Bitcoin trades near $64,600 with limited gains. Crypto-specific pressures, rising bond yields, shrinking stablecoin supplies, and uneven ETF demand have restrained Bitcoin’s upside despite stronger sentiment across US equities.
The S&P 500 has gained 3.12% this month, boosting its market cap by about $2.1 trillion—almost matching the entire global cryptocurrency market. Bitcoin, however, has risen only 2% in the same period, hovering near $64,600. Analysts attribute the divergence to AI-focused stock demand, crypto market headwinds, higher bond yields, and cautious trader positioning.
AI Stocks Drive Wall Street’s Gains
The S&P 500 now holds a record market value near $70.5 trillion, with the index around 7,723 points. The Nasdaq and Dow have also advanced as investors pour capital into large technology companies.
Adam Haeems, head of asset management at Tesseract Group, noted that the equity rally centers on sectors with limited ties to Bitcoin. “Partly because the equity rally is being driven by areas to which bitcoin has little direct exposure, particularly AI and semiconductor stocks,” he said.
Lower oil prices have provided additional support to listed companies through reduced operating costs. Haeems suggested Bitcoin may benefit later from softer inflation expectations and potential Federal Reserve policy changes, though uncertainty around the September outlook limits that path.
Paul Howard, senior director at Wincent, linked the gap to concentrated equity demand. “The stock rally is biased towards AI and mega-caps which doesn’t necessarily translate into crypto flows,” he said.
Crypto Pressures Limit Bitcoin Demand
Bitcoin faces sector-specific challenges that do not affect equities directly, including the $120 million Coldcard exploit, uncertainty surrounding the CLARITY Act, and Strategy’s recent Bitcoin sales.
Haeems said these events have weakened sentiment without triggering a wider credit crisis or forced selling cycle. Strategy has sold Bitcoin for three consecutive months, adding concern for traders monitoring corporate demand.
Rising bond yields also make government debt more attractive than non-yielding crypto assets. Real Treasury returns are at their highest since 2008, encouraging some capital to stay outside digital asset markets.
Stablecoin supplies reflect the same pressure. Haeems noted that USDT supply dropped from about $190 billion in April to $183 billion, while USDC supply declined from $79.5 billion to $72 billion over the same period.
Traders Watch October, ETF Flows
Markus Thielen, founder of 10x Research, said many traders expect Bitcoin’s four-year cycle to produce an October bottom, prompting them to wait rather than build positions during the equity rally.
However, Thielen said Bitcoin’s ability to hold steady despite the Federal Reserve’s firm stance could support another reading. “Traders are underestimating the upside risk from a less hawkish Fed, and overlooking the possibility that the four-year cycle has already bottomed,” he said.
ETF activity has been mixed. US spot Bitcoin funds recently recorded $61.53 million in outflows, ending three weeks of modest inflows. They then attracted $626 million this week, their strongest total since early May.
Giottus CEO Vikram Subburaj said several consecutive inflow days would help confirm stronger institutional demand. He identified Bitcoin support between $63,000 and $63,400, with resistance from $64,500 to $66,000.
Wintermute noted that some ETF demand may reflect arbitrage rather than direct bullish positioning. Analysts expect possible fourth-quarter catalysts from regulatory progress and renewed stablecoin growth.
