Anthropic, SpaceX and Nvidia revive the Nasdaq: the market is betting again on the entire AI value chain

By The Wall Street Journal · October 21, 2026.

A trio of big names in artificial intelligence restored investor appetite for tech stocks this week, according to The Wall Street Journal. Their bullish signals helped the Nasdaq Composite recover much of the previous Friday's drop.

The paper lists three triggers. Elon Musk said SpaceX is now profitable and could merge with Tesla, his electric-car company, valued at $1.5 trillion. A draft of Anthropic's IPO prospectus, seen by the WSJ itself, showed dizzying revenue growth. And on Wednesday, Nvidia's CEO sounded upbeat at a company conference in Berlin, despite a heckler who interrupted him.

The source we have is brief: it does not include the specific figures from Anthropic's prospectus or details of the possible SpaceX-Tesla merger. That is why we don't give them: we are not going to fill a gap the material does not cover. What is on record is the pattern. The headlines point to a market that had been jittery. Among the related articles listed by the WSJ itself is one on “new cracks in the AI trade” that sent Wall Street to its worst week since June.

Our take: what matters is not the one-day rebound but what it reveals. Each of the three players occupies a different link: Nvidia sells the chips, Anthropic develops the models and SpaceX, in Musk's orbit, provides infrastructure and an adjacent business ecosystem. That confidence recovered on news from all three at once suggests investors no longer value AI as a single bet, but as a chain in which each link has to prove revenue and profits.

The most significant point for us is that Anthropic is preparing to go public. A prospectus requires publishing audited figures, and that is good news for public debate. Until now, much of the conversation about AI labs' profitability has relied on leaks and projections. With an IPO, it will be possible to check against official data whether revenue growth supports the investment in compute. It is worth waiting for the final document before drawing conclusions, because a draft is not a verified figure.

There is also a note of caution. A market that moves so much on one-off announcements, with sharp gains and losses on consecutive days, is a market that still doesn't know how to price this technology. In the short term, that volatility can translate into cutbacks, deflating bubbles and hiring decisions made under financial pressure. It is part of the hard transition that should not be glossed over.

In the long run, however, massive funding and the pressure to show real revenue are the fuel that brings the applications that matter closer: drug discovery, personalized medicine and productivity that makes goods and services cheaper. Financial bubbles pass; the accumulated infrastructure and knowledge remain. What we must watch is that the money flows toward proven capability and not toward narrative.
