OpenAI vs Alphabet: Why AI Stock Sentiment Is Shifting in 2025 (2026)

Imagine a tech titan that's been the darling of Wall Street suddenly becoming a drag on the market— that's the dramatic flip-flop we're witnessing with OpenAI right now, as investors grapple with mounting risks in the AI space. But here's where it gets controversial: Is this just a temporary setback, or a sign that OpenAI's pioneering spirit has been overshadowed by more grounded competitors? Let's dive in and unpack what's really happening, breaking it down so even newcomers to the AI world can follow along.

Wall Street's feelings about artificial intelligence-linked firms are undergoing a major shift, and it's largely centered on two key players: OpenAI is facing tough times, while Alphabet Inc. is gaining steam. The creators of ChatGPT are no longer viewed as the trailblazers in AI innovation; instead, they're dealing with doubts about their ability to turn profits and the urgent need to expand quickly to cover their enormous expenses. On the flip side, Google's parent company is stepping up as a well-funded rival with involvement in nearly every aspect of the AI market.

"OpenAI was like the favorite child back in the early part of this year, and Alphabet was seen completely differently," remarked Brett Ewing, chief market strategist at First Franklin Financial Services. "These days, the mood toward OpenAI is far more cautious."

This change is hitting the stocks of companies closely tied to OpenAI hard—think Oracle Corp., CoreWeave Inc., Advanced Micro Devices Inc., Microsoft Corp., Nvidia Corp., and SoftBank, which holds an 11% stake in OpenAI. These shares are getting hammered by heavy selling. In contrast, Alphabet's rising star is lifting not just its own stock but also those of its partners, such as Broadcom Inc., Lumentum Holdings Inc., Celestica Inc., and TTM Technologies Inc.

The turnaround has been swift and striking. Just weeks ago, any link to OpenAI could trigger massive stock surges. Now, those same connections feel like dead weight. This shift matters a lot because OpenAI has been at the heart of the AI excitement that powered the stock market's three-year boom.

"A spotlight has been turned on the intricate financing, the roundabout deals, and the debt problems," Ewing explained. "Sure, this kind of thing might pop up in Alphabet's world too, but it shone brightly as particularly intense for OpenAI, and realizing that flipped the sentiment."

A group of stocks connected to OpenAI has climbed 74% so far in 2025—an impressive feat, but it pales next to the 146% rise in Alphabet-related shares. Meanwhile, the tech-focused Nasdaq 100 Index has risen 22%.

The doubts about OpenAI started bubbling up in August with the release of GPT-5, which drew lukewarm responses. Things heated up last month when Alphabet rolled out its updated Gemini AI model, earning glowing praise. In response, OpenAI's CEO Sam Altman called for a "code red" push to enhance ChatGPT, putting other initiatives on hold.

And this is the part most people miss: Alphabet's advantages stretch way beyond Gemini. It boasts the third-largest market cap in the S&P 500, plus a huge cash reserve. It also runs related businesses like Google Cloud and a semiconductor factory that's catching on. Plus, don't forget its AI data resources, top talent, global reach, and successful offshoots like YouTube and Waymo.

"There's an increasing belief that Alphabet has everything it needs to become the top AI model developer," said Brian Colello, technology equity senior strategist at Morningstar. "Not long ago, investors would have handed that crown to OpenAI. But now, with all the uncertainty, competition, and risks, it's not a sure thing for OpenAI anymore."

Being first or second in this race isn't just about bragging—it's loaded with real financial consequences for the companies and their allies. For instance, if more people start using Gemini, it could slow ChatGPT's growth, making it tougher for OpenAI to afford cloud services from Oracle or chips from AMD.

Meanwhile, Alphabet's collaborators are doing well. Lumentum, which supplies optical parts for Alphabet's data centers, has seen its shares more than triple this year, landing it in the top 30 performers on the Russell 3000 Index. Celestica handles the hardware for Alphabet's AI setup, and its stock is up 252% in 2025. Broadcom, crafting the tensor processing units (TPUs) for Alphabet, has jumped 68% since year's end.

OpenAI has been busy with big deals lately. This flurry "rightfully sparked scrutiny and worries about whether they can afford it all, or if they're overextending," Colello noted. "The timeline for their revenue growth is unclear, and every competitor's advance raises the stakes that they might not hit their goals."

To give credit where it's due, these deals initially thrilled investors, seeming to create the next AI powerhouses. But with the mood change, everyone's adopting a wait-and-see approach.

"When folks believed it could bring in cash and turn profitable, those big deal numbers felt achievable," said Brian Kersmanc, portfolio manager at GQG Partners, managing around $160 billion. "Now, we're seeing disbelief and skepticism kicking in."

Kersmanc compares the AI hype to the dot-com bubble but amplified, and his firm has shifted from heavy tech bets to extreme caution.

"We're steering clear of overhyped areas, many of which OpenAI fueled," he added. "Since so many sectors got caught up in this, the fallout will be painful. It's not just a handful of tech stocks that need correcting—they're big players in the index. All these investments have related trades, like in utilities, with strong correlations. That's our big worry: not just that OpenAI built this story, but that hype lifted everything."

OpenAI's PR missteps haven't helped either. Recently, CFO Sarah Friar hinted that the US government might need to guarantee financing, drawing raised brows. She and Altman later clarified they haven't asked for such backing.

Then there's Altman's chat on the "Bg2 Pod," where he addressed how OpenAI can commit to spending way beyond its income. "If you want to sell your shares, I'll find you a buyer—I just need enough," he quipped.

That flippant reply stood out because HSBC estimates a $207 billion shortfall between OpenAI's current revenue and spending plans through 2033.

"Bridging that gap might require higher-than-expected revenues, smarter cost control, more investments, or debt," analyst Nicolas Cote-Colisson wrote in a note on November 24. With OpenAI projecting over $12 billion in revenue for 2025, its computing expenses "heighten investor anxiety about returns," not just for the company but for the "interwoven AI ecosystem."

That said, firms like Oracle and AMD aren't fully dependent on OpenAI. They thrive in booming markets, and their tech could attract buyers elsewhere. Plus, the stock dips might be buying chances, as ChatGPT-linked companies and their chips are at a discount compared to Gemini counterparts for the first time since 2016, per Wells Fargo analysis.

"I spot a lot of unmet demand and room for growth across sectors, which will drive future expansion," said Kieran Osborne, chief investment officer at Mission Wealth, overseeing about $13 billion. "Making money is the ultimate aim for these firms, and as long as they're chasing that, it strengthens the investment story."

But here's the controversial twist: Could this downfall be self-inflicted, as some critics claim, or is it a necessary correction in an over-hyped industry? Do you agree that Alphabet's broad strengths give it an edge, or should OpenAI's pioneering role keep investors loyal? Share your thoughts in the comments—let's debate if this AI shift signals a new era or just a market hiccup!
