Bitcoin Decouples from S&P 500 as Market Correlation Turns Negative Mid-Cycle

TLDR:

• A $19B leverage wipeout in October 2025 erased Bitcoin’s two-year correlation with the S&P 500 index.
• Bitcoin’s 30-day correlation with equities turned negative after open interest collapsed from $45B to $21.9B.
• Historical halving data shows Bitcoin recoveries begin 30 to 36 months after each halving event occurs.
• Bitcoin now trades as a standalone asset class, no longer functioning as a high-beta equity market proxy.

Bitcoin’s relationship with traditional markets has shifted, leaving many traders reassessing their strategies. For much of 2025, the leading cryptocurrency mirrored equity markets closely.

That dynamic has since broken down. Stocks are climbing to new highs while Bitcoin remains 42% below its peak. Understanding what caused this split matters for anyone tracking the digital asset space right now.

A Leverage Collapse Changed Bitcoin’s Market Structure

A massive liquidation event in October 2025 fundamentally altered how Bitcoin trades. On October 10 and 11, $19 billion in leveraged positions were wiped out across two days. Open interest dropped sharply from $45 billion to just $21.9 billion during that period.

According to Satoshi Club, “70,000 BTC worth of open interest vaporized” in those two sessions alone. The leverage infrastructure that had powered Bitcoin rallies for two years was dismantled rapidly. No significant rebuilding of that structure has taken place since then.

As a direct result, Bitcoin’s 30-day correlation with the S&P 500 turned negative. The two assets now move independently of each other.

This marks a clear structural break from the high-beta relationship that defined Bitcoin through most of the bull run.

Meanwhile, equities have surged on separate catalysts entirely. Iran peace talks, strong AI earnings, and a Magnificent 7 short squeeze are driving stocks higher. The Mag 7 ETF has gained 18% since March 30, with Nvidia posting 11 consecutive green days.

Bitcoin’s Halving Cycle Points to a Delayed Recovery Timeline

Bitcoin’s current position within its halving cycle offers useful historical context. The most recent halving occurred in April 2024, and the next one is scheduled for March 2028. That places the market precisely at the midpoint of the current cycle.

Historical patterns show that mid-cycle drawdowns consistently flush out overleveraged and impatient participants.

Post-halving tops have typically formed between 12 and 18 months after the halving event. Based on that template, Bitcoin’s peak for this cycle likely already occurred.

The historical template further shows that drawdown bottoms tend to form between 24 and 30 months post-halving.

Recovery phases have generally begun between 30 and 36 months after the halving. A new all-time high typically arrives heading into the following halving.

Satoshi Club noted that Bitcoin is “not digital Nasdaq anymore,” adding that it now operates on “its own cycle driven by its own mechanics.”

That separation removes it from the easy beta trade category. However, it also reinforces Bitcoin’s identity as a standalone asset class with a distinct rhythm.
