The Smartest Money Indicator Nobody Watches: What Corporate Stock Issuance Is Telling Us About AI

By Luke  |  EverHealthAI  |  June 2026

There is a particular kind of market signal that valuation ratios miss entirely — and right now, it is flashing.

When SpaceX announced a $60 billion all-stock acquisition of Cursor, the coding assistant that popularized "vibe-coding," most coverage focused on what it meant for Elon Musk's competitive position in corporate AI. That's the wrong lens. The more revealing detail is the word "all-stock." SpaceX didn't pay cash. It didn't raise debt. It used its own shares as currency — and that choice, multiplied across the market, is one of the most reliable warning signs in investing that few retail investors know how to read.

The principle is simple, and it comes from one of the oldest ideas in value investing: companies, like investors, are constantly being offered prices by the market. And companies tend to be very good at recognizing when those prices are too high.

The Logic: Why Stock Issuance Is a Confession

Every company financing an acquisition or major investment faces a basic choice: pay with cash, raise debt, or issue stock. That choice is not random. It is a calculated judgment about relative cost.

When interest rates are low, debt is cheap, and rational companies lean on borrowing. When a company's stock price is high relative to its underlying business, issuing shares becomes the "cheap" option — because each share sold raises more capital while giving away a smaller real claim on the business. The logic runs in reverse too: companies in genuine distress are forced to sell stock at low prices, which dilutes existing shareholders and punishes the share price. Healthy companies, by contrast, sell stock when they believe the market is offering them a generous price for it.

Benjamin Graham captured this decades ago with his "Mr. Market" metaphor — the manic-depressive trading partner who quotes wildly different prices day to day, sometimes far too high, sometimes far too low. Investors are taught to buy when Mr. Market panics and sell when he's euphoric. What gets discussed less often is that companies face the same Mr. Market — and when they collectively decide to sell him their stock, they are implicitly telling you that they think his prices are too high.

In any single case, issuing equity can be perfectly sensible. Equity is well suited to risky ventures precisely because it doesn't have to be repaid like debt — if the bet fails, there's no creditor to face. Balancing debt and equity is ordinary corporate finance. But the signal isn't in any individual deal. It's in the aggregate. When companies as a group tip toward selling stock, it is a strong indication that equity prices have run ahead of fundamentals.

The Historical Pattern Is Hard to Ignore

This is not a theoretical concern. The pattern has repeated at the most notorious market peaks of the past quarter-century.

During the dot-com bubble, rising valuations triggered waves of IPOs and secondary issuance, alongside an M&A boom in which roughly two-thirds of deal value was financed with newly issued stock — the highest equity-financing share in records going back to 1990. The post-pandemic SPAC mania produced a similar surge, with about 45% of M&A value in 2020-21 financed by equity, the second-highest reading on record. In both cases, companies were doing exactly what the theory predicts: using richly valued shares as currency because that currency was cheap to spend.

Today, the same behavior is reappearing. Giant IPOs are launching — SpaceX among them — and companies are financing close to half the cost of acquisitions with stock in the current quarter. Alphabet recently completed a record-breaking secondary share issue. Investor demand for AI-linked equity is, in part, being met not by existing shares changing hands, but by the creation of entirely new stock to sell into that demand.

The Counterintuitive Contrast: When Cheap Debt Is the Bigger Danger

Here is where the analysis gets genuinely useful, because the stock-issuance signal cuts both ways — and its absence can be more dangerous than its presence.

Consider 2007. Pre-financial-crisis deal value peaked at around $910 billion in the year to September 2007, just before the economy's foundations gave way. But only 19% of that was financed with stock. Why so little equity? Because debt was extraordinarily cheap, fueled by an explosion of structured credit products. The bubble that year was not in equities — it was in the debt markets. Companies weren't selling overpriced stock; they were gorging on underpriced debt.

The lesson is important: the financing mix tells you where the excess is. A surge in equity financing points to an equity bubble. A surge in cheap-debt financing points to a credit bubble. The current environment, with equity financing climbing toward half of deal value, is sending an equity-market signal — which, paradoxically, may be less systemically dangerous than the debt-driven excess of 2007, even if it's more visible. Equity-funded excess tends to hurt shareholders when it unwinds. Debt-funded excess tends to take down the financial system.

For investors, that distinction matters for risk assessment. An AI-driven equity bubble that unwinds would inflict real damage on stock portfolios — but it is a different, and arguably more contained, category of risk than a leverage-driven crisis.

What the Market May Be Getting Wrong

The dominant framing treats heavy AI investment as straightforward confirmation of the theme's strength: money flooding in must mean the opportunity is real and large. That framing isn't wrong about the opportunity — AI is genuinely transformative. But it conflates two different things: the long-term value of the technology, and the current price being paid for exposure to it.

Corporate financing behavior separates those two cleanly. When companies use their own stock as acquisition currency, they are revealing that they consider their shares more valuable as a payment method than as something to hold — which is to say, they think the market is valuing them generously. That's a judgment from the people with the best possible information about their own businesses. It deserves more weight than a P/E ratio.

And the P/E comparison is the deeper point. Traditional valuation gauges — price-to-earnings, price-to-book, price-to-sales, price-to-free-cash-flow — are genuinely flawed tools. They often disagree with each other, they have relatively short usable histories, and their baselines shift as accounting standards and corporate structures evolve. Book value in particular now requires so many adjustments that it has become nearly useless as a standalone measure. Earnings are soaring while free cash flow is plunging at many AI-exposed firms, which means different ratios are telling opposite stories about the same companies. Against that noisy backdrop, corporate financing behavior offers something cleaner: a revealed preference. Not what companies say about their valuations, but what they do with them.

Cyclical or Structural?

The AI investment theme is structural. The financing pattern around it is cyclical — and that's precisely the distinction investors need to hold in their heads simultaneously.

The technology's long-term trajectory does not depend on whether this quarter's M&A is equity-financed. But the price investors are paying for AI exposure today is being shaped by a classic late-cycle dynamic: euphoric demand pulling new supply into existence. That dynamic has resolved the same way every previous time it has appeared at this intensity — not with the underlying theme being discredited, but with the prices paid for it correcting, sometimes severely. The dot-com crash didn't mean the internet was a fad. It meant the prices paid for internet exposure in 1999 were wrong. The AI equivalent of that distinction is the single most important thing for investors to keep clear right now.

What to Watch Next

The money flooding into AI is real, and so is the technology. But the way that money is being raised and spent is sending a quieter, more reliable message than the headlines about valuations and breakthroughs. When the companies with the best view of their own worth start treating their shares as expensive currency to spend rather than valuable assets to hold, it is worth asking why — and whether you should be doing the same math they are.
