Bitcoin (BTC) has outperformed the S&P 500 in half of US trading sessions over Glassnodes latest measurement period, ending a prolonged stretch of losing more sessions than it won.
Key points:
- Bitcoin beat the S&P 500 by returns in 50% of US trading sessions over the past 90 sessions, per Glassnode data.
- Bitcoins session win rate has not exceeded 50% since March 2025.
- The S&P 500 gained an average of 10.7% in the three months after the seven midterm elections since 1922 in which Democrats won both chambers under a Republican president.
Bitcoin ends stretch of weakness against S&P 500
Data from onchain analytics platform Glassnode shows that Bitcoin outperformed the S&P 500 in 50% of Wall Street trading sessions over a rolling 90-session period.
The reading, covering the 90 sessions through Wednesday, marks an improvement after an extended period in which Bitcoin lost more sessions than it won.
“The win rate has not been above 50% since March 2025; for most of the past year, Bitcoin lost more sessions than it won,” Glassnode wrote in the latest edition of its regular newsletter, The Week Onchain.
“A return to an even split ends a long stretch of underperformance. Should the win rate climb above 50% and hold there, it would show Bitcoin regaining strength against equities.”
Glassnode added that Bitcoins average per-session gains were also “slightly higher” than those of the S&P 500.
Historical data favors stocks after Democratic midterm sweeps
Democrats wins in the US midterm elections have also drawn attention to historical stock market gains following similar results.
Data from crypto asset manager Capriole Investments shows that Democratic sweeps of Congress under Republican presidents have historically been followed by strong S&P 500 returns.

Of the 26 midterm elections since 1922 (excluding this years vote), Democrats won both the House and Senate under a Republican president seven times. The S&P 500 gained an average of 10.7% over the following three months.
Average gains were 17.5% after six months and 15.5% after a year.
“There is simply no better election result for markets than we just had,” Capriole founder Charles Edwards commented on the data in a post on X.
