Megacap S&P 500 rally leaves Bitcoin exposed

On May 13 the S&P 500 closed at an all-time high driven by gains in a handful of megacap technology stocks while Bitcoin registered an intraday low of $78,759.70 after falling below $80,000. Spot Bitcoin ETF flows reversed in early May and liquidity measures tightened during the period.

The equity advance was concentrated. QQQ rose about 1.06% and Nvidia gained 2.84% on May 13, while seven of 11 S&P 500 sectors finished lower. Declining stocks outnumbered advancing stocks on both the NYSE and Nasdaq. The top 10 S&P companies account for roughly 36.5% of the index by market capitalization, with Nvidia, Apple and Microsoft among the largest contributors to the index gain. Analysts point to earnings revisions, AI-related revenue growth and large share buyback programs as factors supporting these cash-generating companies.

Spot Bitcoin ETFs posted heavy inflows in early May and then shifted to outflows. Net ETF inflows were $629.8 million on May 1 and $532.3 million on May 4, followed by inflows of $467.3 million on May 5. Flows reversed to outflows of $268.5 million on May 7, $145.7 million on May 8 and $233.2 million on May 12. Bitcoin perpetual futures funding rates had been negative for 74 consecutive days entering the week, average daily spot trading volume for BTC sat near $2.7 billion, and the price closed below its 200-day moving average on multiple approaches.

Macro data in April added to the liquidity backdrop. The producer price index rose 1.4% month over month and 6.0% year over year, the largest 12-month gain since December 2022. Energy costs led the monthly increase, with gasoline up 15.6%. Traders increased the probability of an additional Federal Reserve rate hike by December to about 34.3%, up from roughly 15% a week earlier. Treasury yields and the U.S. dollar rose after the report.

Institutional balance sheet items also affected market liquidity. The Federal Reserve’s balance sheet held about $6.71 trillion in total assets as of May 6, reserve balances exceeded $3 trillion, and the Treasury General Account stood near $878 billion. Treasury projections show the TGA rising toward $900 billion to $950 billion by the third and fourth quarters of fiscal 2026. A Treasury advisory committee noted that oil prices had climbed nearly 80% since the start of 2026, a supply-side factor that could sustain inflationary pressure.

Market data show Bitcoin continues to move with equity sentiment but with limited upside participation during concentrated equity rallies. The 30-day correlation between Bitcoin and the Nasdaq remained above 0.7. Research identified a pattern in which Bitcoin’s upside beta often fades when the Nasdaq gains more than 10% over a 30-trading-day stretch. From March 30 to May 13, Nvidia rose about 45% and QQQ gained about 28%, while Bitcoin advanced roughly 4% before slipping below $80,000.

Analysts outline scenarios for Bitcoin depending on liquidity and inflation developments. In a bullish scenario, moderating inflation, lower Fed hike odds and resumed ETF inflows could let Bitcoin reclaim $80,000–$85,000 and reach higher 12-month targets cited by some banks. In a base scenario of sticky but not worsening inflation, ETF flows may remain mixed and Bitcoin could trade in a range. In a downside scenario where inflation feeds into consumer measures and hike odds rise, continued ETF outflows and tighter liquidity could test the $74,000–$68,000 band, with more adverse projections placing the price lower.

Three consecutive days of ETF outflows through May 12 were recorded. Derivative liquidations and retail stop-loss orders are concentrated in the $74,000–$68,000 range, while megacap technology companies continued to report earnings-related strength during the same period.
