Artificial intelligence stocks delivered a split-screen moment on Tuesday: chip makers rallied hard, while private-market chatter suggested a cooler reception for one of the sector's most anticipated IPOs. Reports that Anthropic's prospective public listing is being discussed at a valuation of $1.2 trillion to $1.3 trillion—well below the loftier figures floated earlier—offered a reality check for AI dealmaking, even as semiconductor shares surged.
Chips lead the way
The rally was led by semiconductors, with the SPDR S&P Semiconductor ETF (XSD) climbing 3.2% and the Philadelphia Semiconductor Index gaining 2.6%. The broader tech sector rose more modestly, underscoring that the enthusiasm was concentrated in the hardware layer of the AI stack.
The logic is straightforward: chips and servers are the most immediate bottleneck for building AI. Companies can't train models or run data centers without them, so investors tend to reward the firms selling the picks and shovels even when longer-dated AI platform stories get repriced. This dynamic has been a recurring theme in recent months, as seen in chip stocks leading a Nasdaq rebound on the back of jobs data.
Anthropic's valuation talk
Anthropic, the AI startup behind the Claude chatbot, has been the subject of IPO speculation for months. The reported $1.2-1.3 trillion range is still enormous by any historical standard—far larger than most companies that have gone public. But it represents a step down from some of the more exuberant private-market valuations that had been floated, suggesting that investors are becoming more discerning about AI companies that have yet to prove durable profitability.
This isn't unique to Anthropic. Across the AI landscape, there's a growing gap between companies that generate revenue today (like chipmakers) and those that promise future dominance (like model developers). The latter often require massive capital spending on computing infrastructure, which weighs on near-term earnings.
OpenAI's data center commitment
Adding to the mixed picture, OpenAI—Anthropic's chief rival—said it will continue funding data centers. That's a signal that the biggest players still see infrastructure as a strategic priority, even as investors question valuations. For chipmakers, that's a bullish sign: continued data center spending means continued demand for semiconductors.
But it also highlights the capital intensity of the AI race. Building and operating data centers costs billions, and those costs are typically borne before any revenue flows in. That's a key reason why some investors are wary of AI platform companies, even as they pile into chip stocks.
What it means for investors
For everyday investors, the takeaway is that “AI” is not a single trade. The sector spans everything from semiconductor manufacturers to cloud providers to software startups, and they don't always move in lockstep. When one part of the AI ecosystem gets repriced, it doesn't necessarily drag down the rest.
This split-screen action is a reminder to look under the hood of any AI-related investment. A company that sells the physical infrastructure of AI—chips, servers, networking gear—may have a very different risk profile than one that develops models or applications. The former tends to have clearer revenue streams and more immediate demand; the latter may offer bigger long-term upside but also more uncertainty.
It's also worth noting that private-market valuations, like the reported Anthropic range, are not the same as public market prices. They are based on negotiations between a select group of investors and can be influenced by factors like fundraising needs and strategic positioning. When a company eventually goes public, the market may assign a very different value.
Broader market context
The chip rally comes amid a backdrop of mixed economic signals. Strong jobs data have kept yields high, which can pressure growth stocks, but tech has shown resilience. Meanwhile, energy stocks have been volatile as earnings season unfolds, and AI regulation fears have hit European markets.
For now, the AI trade remains one of the most closely watched in markets. The combination of a chip rally and a more sober IPO valuation suggests that investors are still enthusiastic about AI's potential, but they're becoming more selective about which parts of the story they're willing to pay up for.
As always, it's wise to remember that markets can be fickle. Today's chip rally could fade tomorrow, and IPO valuations can change quickly. The key is to focus on the fundamentals of individual companies rather than getting swept up in the broader AI narrative.
