Why the current AI mania is not a bubble – and that’s great for Bitcoin

Bitcoin’s macro setup is increasingly tied to the same forces driving the S&P 500 to new highs: liquidity, concentration, rate expectations, and investor tolerance for stretched valuations. The current S&P 500 structure shows an index still moving in a powerful long-term uptrend, with price near 7,365 on the weekly chart, while valuation indicators sit in historically elevated territory. That combination creates a constructive backdrop for Bitcoin in the near term, with a clear condition attached. BTC benefits while the equity trend remains intact. Fragility rises if expensive equities begin to roll over under the weight of rates, earnings pressure, or volatility. The current market regime is best understood through the three layers of the S&P 500 chart below. S&P 500 performance since 2019 The first layer is price. The index remains in a secular advance, with higher highs and higher lows surviving the dot-com crash, the global financial crisis, the COVID shock, the 2022 tightening cycle, and the latest phase of AI-led equity concentration. The second layer is the equity risk premium-style signal, shown by the SPX ECY reading near 0.70. That level suggests investors are accepting less compensation for holding equities relative to the rate environment. The third layer is valuation. The normalized CAPE Z-score analyzer shows a CAPE reading around 38.34 and a Z-score near 2.26, placing the market in a zone the chart labels as highly overvalued. Independent CAPE datasets, including the Shiller PE ratio , show the same broad context: U.S. equities are expensive compared with long-run history. For Bitcoin, the conclusion is direct. The current equity setup remains supportive for high-beta assets as long as investors keep treating expensive valuations as a feature of a durable growth regime. BTC sits further out on the risk curve than the S&P 500 and Nasdaq. When macro confidence expands, Bitcoin usually receives the amplified version of that capital flow. When macro confidence contracts, Bitcoin usually absorbs the amplified version of the drawdown. Equity valuations are stretched while the trend still supports Bitcoin’s risk appetite The S&P 500 chart shows a market that has become expensive while maintaining trend control. That distinction is central for Bitcoin. S&P 500 performance since 1979 Expensive markets can keep rising for long periods when earnings, liquidity, and narrative strength remain aligned. The late 1990s showed how far a technology-led cycle can run before valuation discipline returns. The 2020 and 2021 cycles showed how far risk assets can move when liquidity expansion, falling real yields, and speculative capital combine. The 2022 cycle showed the other side of the framework, when higher rates compress duration assets and expose crowded positioning. The current setup borrows from all three periods. As in the dot-com era, leadership is concentrated around a transformational technology theme. I even highlighted the comparison and potential red flag in a recent article.

Apr 29, 2026 · Liam 'Akiba' Wright In the late 1990s, the internet provided the dominant justification for higher multiples. Today, AI plays that role. The index has become increasingly dependent on a small group of mega-cap technology companies, with the so-called Magnificent Seven accounting for a large share of S&P 500 performance and index weight. That concentration gives the index strong upside when leadership works. It also narrows the margin for error if leadership weakens. However, today’s leaders have large revenue bases, high margins, and significant free cash flow, which gives the current equity cycle a stronger earnings foundation than the speculative internet bubble. Even so, the operational market signal is still late-cycle in character. The S&P 500 is rising while valuation support is thin, risk premium compensation is compressed, and the index is leaning heavily on the market’s confidence in future productivity gains. Bitcoin tends to perform well in precisely that kind of environment. When equity investors accept valuation stretch in exchange for future growth, crypto investors often move even further along the same curve. That is why the current S&P 500 setup is constructive for BTC rather than immediately bearish. The chart shows a market priced for execution. Bitcoin thrives when execution risk is underpriced, liquidity remains available, and investors believe the next phase of growth will justify today’s valuation premium. In that regime, BTC behaves less like a defensive hedge and more like a high-beta expression of macro confidence. The near-term implication is therefore positive. If the S&P 500 continues to hold its weekly trend, volatility remains contained, and AI-led earnings expectatio
