Bitcoin gained 2.6 percent Monday, crossing above $64,000 for its best single-day performance in over a month. The S&P 500 closed down 0.52 percent the same session, putting the two assets on opposite sides of the ledger for the first time in weeks.

Blockchain analytics firm Glassnode put the rarity in plain numbers: BTC has outperformed the S&P 500 on roughly one-third of trading days over the past three months. That means on two out of every three sessions, U.S. equities either held ground or beat crypto outright.

The three-month window tells a sharper story than Monday's bounce. From mid-May through mid-August, Bitcoin dropped approximately 20.7 percent while the S&P 500 gained between 4.6 and 4.8 percent over the same period. BTC traded near $63,900 to $64,000 in the days leading into Monday before the session's move higher.

For most of Bitcoin's history, the dynamic ran the other way. BTC carried a higher beta than equities—meaning it amplified market moves in both directions, outpacing stocks when risk appetite was open and falling harder when it closed. Acting as a laggard against a rising equity market inverts that historical role.

Glassnode identified two forces behind the sustained underperformance. First, the AI stock rally on Wall Street has pulled capital toward technology names and away from crypto. Second, Bitcoin's own four-year cycle has entered a bear phase after peaking above $126,000 in October last year. That cycle is expected to find its bottom around October of this year.

The AI equity trade has been direct competition for discretionary capital. Investors rotating into Nvidia, Microsoft and other AI-infrastructure names are allocating from the same risk budget that previously reached into digital assets. With those equities posting strong returns through the spring and summer, the opportunity cost of holding BTC has risen.

The bear-market dynamic within Bitcoin's cycle adds a demand-side drag. Post-peak phases historically see reduced spot buying, lighter ETF inflows and muted retail participation. Bitcoin spot ETFs have been trading since Jan. 2024, giving institutional allocators a clean vehicle in and out—but net flows have reflected the broader hesitation rather than offsetting it.

Fed minutes from the July meeting are due Wednesday, and traders across asset classes are in a holding pattern ahead of the release. The S&P 500 is down 0.5 percent today at 7,745. The Dow Jones sits at 53,460, off 0.5 percent. The Nasdaq has shed 0.3 percent to 26,645. Bitcoin, by contrast, is holding gains at $64,143, up 0.9 percent over the past 24 hours.

The Crypto Fear & Greed Index sits at 41—in Fear territory—reflecting the broader hesitation in digital assets even as Monday's session produced a positive print. That reading is consistent with a market where buyers exist but conviction is limited.

If the July Fed discussion leaned more hawkish than markets currently price, equity pressure and a stronger dollar would test whether BTC's Monday resilience was structural or situational. The four-year cycle bottom expected around October sets a near-term floor thesis, but the AI capital rotation isn't a factor Bitcoin can outrun on its own.
