OpenAI’s Market Glow Fades as Alphabet Emerges as AI Powerhouse

Wall Street’s sentiment toward artificial intelligence companies is shifting sharply. OpenAI, once hailed as the market darling, is facing skepticism over its profitability and massive spending, while Alphabet Inc., Google’s parent company, is emerging as a dominant competitor in the AI space.

“Earlier this year, OpenAI was the golden child, and Alphabet lagged in perception,” said Brett Ewing, chief market strategist at First Franklin Financial Services. “Now, sentiment toward OpenAI is much more tempered.”

The shift has affected stocks connected to OpenAI — including Oracle Corp., CoreWeave Inc., AMD, Microsoft, Nvidia, and SoftBank — which have come under selling pressure. Meanwhile, Alphabet’s momentum is boosting associated stocks such as Broadcom, Lumentum, Celestica, and TTM Technologies.

The reversal reflects concerns about OpenAI’s complex financing, circular deals, and debt commitments. While OpenAI’s ecosystem stocks gained 74% in 2025, Alphabet-exposed stocks soared 146%, outperforming the Nasdaq 100 Index’s 22% increase.

The skepticism intensified after OpenAI unveiled GPT-5 in August to mixed reviews, while Alphabet’s Gemini AI release received wide acclaim. In response, OpenAI CEO Sam Altman initiated a “code red” to improve ChatGPT, delaying other projects to focus on its flagship product.

Alphabet’s Edge
Alphabet’s strength stems not just from Gemini, but from its deep pockets, diverse AI-related businesses, and subsidiaries such as Google Cloud, YouTube, and Waymo. “Alphabet has all the pieces to become the dominant AI model builder,” said Brian Colello, technology equity strategist at Morningstar.

By contrast, OpenAI faces uncertainty in revenue growth and funding for ambitious AI deals. If competitors like Alphabet draw users away from ChatGPT, OpenAI could struggle to pay for cloud computing from Oracle or chips from AMD.

Market Implications
OpenAI’s ambitious deals initially excited investors, but growing doubts have created a “wait-and-see” approach. “People have stopped believing and started questioning,” said Brian Kersmanc, portfolio manager at GQG Partners. He described the AI euphoria as “dot-com era on steroids,” noting a shift from tech optimism to skepticism.

Complicating matters, OpenAI’s public statements and PR missteps have fueled uncertainty. CFO Sarah Friar’s suggestion of a potential U.S. government backstop and Altman’s comments on share sales highlighted the revenue-spending gap, estimated at $207 billion through 2033 by HSBC.

Despite concerns, companies like Oracle and AMD retain independent growth potential, and some analysts see a buying opportunity in discounted shares tied to OpenAI. “Monetization is the end goal, and the untapped demand across industries will support growth,” said Kieran Osborne, CIO at Mission Wealth.

As OpenAI adjusts its strategy and Alphabet continues to consolidate its AI leadership, Wall Street is closely watching which company will emerge as the long-term winner in the next generation of AI technologies.
