Goldman Sachs CEO warns markets in 'greed mode' amid AI IPO wave

The market is running on greed, not reason
Goldman Sachs CEO warns investors that sentiment driving AI IPO wave has detached from fundamental valuation.

As three of the most consequential initial public offerings in recent memory prepare to arrive — Anthropic, SpaceX, and OpenAI among them — Goldman Sachs has offered a rare and sobering word from within the machinery of finance itself: the market is no longer pricing these companies on what they are, but on what investors wish them to be. It is an old pattern dressed in new technology, and the warning carries unusual weight precisely because it comes from an institution that stands to profit from the very frenzy it is naming. History reminds us that the distance between collective desire and underlying reality has a way of closing, and not always gently.

  • Goldman Sachs leadership has openly characterized current investor sentiment as 'greed' — a striking self-indictment from a firm positioned to underwrite the very IPOs driving that mood.
  • Three potentially record-breaking public offerings from Anthropic, SpaceX, and OpenAI are converging on the market simultaneously, creating a pressure event unlike anything Wall Street has recently absorbed.
  • Private secondary markets for these companies' shares have already exposed deep disagreement about their true worth, with prices swinging wildly depending on who is buying and when.
  • Analysts across major firms are issuing caution even as bullish sentiment dominates — a contradiction that signals investors are aware of the risk but betting others will blink first.
  • The central question now is whether these IPOs will force a rational reckoning with valuations or simply lock in the euphoria, leaving public investors to absorb whatever correction follows.

The Goldman Sachs chief executive has issued a pointed warning to investors watching the artificial intelligence sector: the market is running on greed, not reason. As Anthropic, SpaceX, and OpenAI prepare for what analysts are calling the three largest IPOs in history, Wall Street finds itself suspended between genuine excitement about transformative technology and deep unease about valuations that may have already drifted beyond what fundamentals can support.

What makes this moment distinct is not just the scale of the offerings, but the contradiction at their center. Bullish sentiment and explicit risk warnings are coexisting in the same breath. Investors want exposure to these companies — and they also sense that something in the pricing has come unmoored. The private secondary markets for SpaceX and OpenAI shares have already revealed how contested these valuations are, with prices reflecting wildly different assessments of what these businesses are actually worth.

History offers a familiar pattern: mega-IPOs create moments of price discovery, but they also tend to crystallize the euphoria of the moment. Once shares begin trading publicly, the narrative hardens. Early private investors have every incentive to see their valuations confirmed, and new public investors arrive with fresh capital and conviction, capable of carrying prices higher regardless of whether the underlying business has materially changed.

That Goldman Sachs is sounding this alarm — from a firm that profits from underwriting these very offerings — suggests the concern is not performative. When an institution with skin in the game signals that greed is driving the market, it is not a casual observation. What happens next rests on whether these three companies can deliver on the expectations their valuations have already priced in. If they cannot, the correction may be as large as the ambition that preceded it.

The Goldman Sachs chief executive has a warning for investors watching the artificial intelligence sector: the market is running on greed, not reason. As three of the most anticipated initial public offerings in history prepare to launch—Anthropic, SpaceX, and OpenAI among them—Wall Street is caught between genuine excitement about the technology and deep unease about valuations that may have already spiraled beyond what fundamentals can support.

The timing is not accidental. These companies represent the cutting edge of two transformative industries: artificial intelligence and commercial space exploration. Their potential is real. Their market appeal is undeniable. But the Goldman Sachs leadership's characterization of current sentiment cuts to a familiar problem in finance: when everyone believes in a story, prices stop reflecting reality and start reflecting collective desire.

What makes this moment distinct is the scale. Wall Street is bracing for what analysts are calling the three largest IPOs in history. That magnitude alone reshapes the conversation. These are not small offerings testing market appetite. These are transformative capital events that will reshape how investors think about technology, innovation, and risk for years to come.

Yet caution is spreading through the financial establishment. Analysts across major firms have begun flagging the risks embedded in these offerings. The contradiction is stark: bullish sentiment coexists with explicit warnings. Investors want exposure to these companies. They also sense that something in the pricing may have come unmoored from reality. The secondary market for shares in these firms—the murky, private trading that happens before public listing—has already revealed how contested valuations have become. SpaceX and OpenAI shares have traded hands at prices that reflect wildly different assessments of what these businesses are actually worth.

The question hanging over the market is whether the IPO wave will correct these imbalances or amplify them. History suggests that mega-IPOs often do both: they create moments of price discovery, but they also lock in the euphoria of the moment. By the time shares begin trading publicly, the narrative has already hardened. Investors who bought in at private valuations have every incentive to see those prices validated. New public investors arrive with fresh capital and fresh conviction. The momentum can carry prices higher, regardless of whether the underlying business has changed.

For Goldman Sachs to be sounding this particular alarm—from a firm that profits handsomely from underwriting these very offerings—suggests the concern runs deep. The bank has skin in the game. Its warnings carry weight precisely because they come from an institution that benefits from the deals proceeding. When such a firm signals that greed is driving the market, it is not a casual observation. It is a statement that even those positioned to gain from the frenzy see danger ahead.

What happens next depends on whether these three companies can deliver on the expectations their valuations have already priced in. If they do, the market will have been prescient. If they do not, the correction could be severe. For now, Wall Street waits, caught between the pull of innovation and the weight of caution.

Markets are in greed mode amid the wave of AI initial public offerings

Why would Goldman Sachs warn about greed if they're the ones underwriting these deals? Doesn't that seem contradictory?

Model

Not really. They profit either way—from the underwriting fees, from advisory work, from trading around the IPOs. The warning isn't about whether the deals happen. It's about the price at which they happen. If valuations collapse after listing, it damages their reputation and their future business. So they're protecting their long-term interests by flagging the risk.

Inventor

But if the market is truly in greed mode, shouldn't these IPOs be delayed or repriced?

Model

That's the tension. The companies themselves have no incentive to delay. They want to go public now, while sentiment is hot. And the underwriters can't force them to wait. What Goldman is doing is documenting the warning—so when things potentially correct, they can say they saw it coming.

Inventor

What about the investors buying these shares? Are they aware of the risk?

Model

Some are. The sophisticated ones certainly are. But IPOs attract retail investors who see the narrative—AI is the future, SpaceX is revolutionary—and want a piece. They may not be pricing in the possibility that the stock could fall 30, 40, 50 percent from the opening price.

Inventor

Has this happened before?

Model

Constantly. Dot-com bubble, 2008, crypto boom. Every cycle has a moment where insiders start warning about excess, and the market ignores them because the story feels too good to be false.

Inventor

So what's the actual risk here? That these companies aren't worth what people think?

Model

That's part of it. But the bigger risk is that even if they're good companies, they're priced for perfection. Any disappointment—slower growth, higher costs, regulatory headwinds—and the stock reprices sharply downward. The market is pricing in a very specific future. Reality rarely cooperates.
