Here’s what Bitcoin’s S&P 500 catchup means for BTC’s $90K target

Bitcoin has suddenly regained the relative ground it had lost to the S&P 500 over the previous three months. In other words, Bitcoin had been performing worse than U.S. large-cap stocks during that period.

However, its sharp rally over the past 72 hours was strong enough to close that entire performance gap.

According to Glassnode’s session rewind chart, over the past three months, the BTC-to-S&P 500 relative-performance ratio has declined from around 3x to nearly 2.2x.

However, Bitcoin’s sharp rally over the latest four trading sessions pushed that ratio back up to approximately 2.82x. Though the S&P 500 is still up around 20% from the chart’s September 2025 starting point, Bitcoin has clearly shown its ability to recover lost ground quickly.

What pushed Bitcoin to close this gap in a few days?

This comes on the heels of BTC’s price action rallying from $62K to around $78K in a few days.

Besides the price action, other factors like the Bitcoin [BTC] ETF market, which recorded $1.92 billion in the past week, expectations around U.S. crypto legislation, and Treasury actions that helped calm bond-market stress also helped Bitcoin outweigh S&P 500. 

However, this does not mean that Bitcoin’s underperformance is permanently over or that a new bull market is guaranteed. This is because as a result of the rally, the RSI index has now entered the overbought territory. As the pattern has been, every race to the overbought or oversold territory has called for a pullback, and so it might happen again.
