OpenAI Plans 2026 IPO as Anthropic Closes the Gap: What’s Happening

The competitive landscape at the top of the AI industry is shifting. OpenAI, long seen as the runaway leader in generative AI, is now preparing for a public listing later in 2026 even as reports suggest rival Anthropic has been steadily gaining ground — overtaking OpenAI in self-reported revenue projections and making inroads in the business subscription market. Here’s what’s driving this shift and what it could mean for the AI industry heading into a pivotal stretch.

OpenAI’s Path to an IPO

OpenAI has been preparing for an initial public offering targeted for the fourth quarter of 2026. The company has been building out its finance leadership team ahead of the listing, including hiring a chief accounting officer and a corporate business finance officer to oversee investor relations, moves widely seen as standard groundwork ahead of going public.

Leadership Is Reportedly Mixed on the Move

CEO Sam Altman has expressed some reluctance about taking OpenAI public, reportedly calling the process “really annoying” in past remarks. Despite that hesitation, OpenAI’s leadership has continued moving forward with IPO preparations, with some responsibilities for the listing process reportedly being delegated to other senior executives at the company.

Competitive Pressure Is a Factor

Part of what’s driving the urgency around OpenAI’s IPO timeline appears to be competitive pressure from Anthropic, which is also reportedly preparing for its own path toward a public listing. Executives at OpenAI have reportedly expressed concern about losing ground to Anthropic in the race to go public, adding pressure to move forward despite Altman’s own reservations.

Anthropic’s Growing Position in the AI Market

While OpenAI has long held a commanding lead in headlines and consumer name recognition, recent reporting suggests Anthropic has been closing the gap in key business metrics.

Revenue Projections Have Shifted

According to reporting, Anthropic has overtaken OpenAI in terms of self-reported revenue trajectory. OpenAI has said it’s on pace to generate between $25 billion and $33 billion in annualized revenue based on its most recent disclosures, while Anthropic has said it expects to reach roughly $47 billion and become profitable by 2029 — a year ahead of OpenAI’s own profitability targets.

Business Subscriptions Are a Key Battleground

Data cited from Ramp indicates Anthropic overtook OpenAI in business subscriptions earlier in the year, a notable shift given how central enterprise adoption has become to the long-term business models of major AI labs. Separate data has also shown that monthly visits to ChatGPT fell below a majority share of the generative AI market for the first time, suggesting that consumers and businesses alike are increasingly willing to switch between different AI platforms rather than default to a single provider.

Why This Shift Matters for the AI Industry

The competitive dynamic between OpenAI and Anthropic reflects a broader maturing of the AI industry, where early-mover advantage is proving less durable than some expected.

Enterprise Trust Is Becoming a Differentiator

As AI tools become more embedded in everyday business workflows, factors like reliability, safety practices, and enterprise-specific features appear to be playing a growing role in where companies choose to direct their AI spending, rather than name recognition alone.

Public Listings Could Reshape the Competitive Landscape

Both companies moving toward public listings would mark a significant shift for an industry that has largely operated with immense private valuations and limited public financial transparency. Public listings would require far greater disclosure of financial performance, potentially giving investors and competitors alike a much clearer picture of how these companies are actually performing.

What to Watch Going Forward

Several developments are likely to shape how this competitive dynamic plays out over the coming months.

IPO Timing and Market Conditions

Broader market conditions, including interest rate policy and investor appetite for large tech listings, will likely influence the final timing and success of any IPO from either company. 2026 has already been described as a potentially strong year for major stock market debuts following a previous slowdown in new listings.

Continued Competition on Revenue and Adoption

Whether OpenAI can defend its lead in overall market share, or whether Anthropic’s momentum in enterprise adoption continues to build, will likely remain one of the most closely watched storylines in the AI industry through the rest of the year.

Final Thoughts

The AI industry’s competitive landscape looks notably different than it did just a year or two ago, with Anthropic emerging as a serious challenger to OpenAI’s early dominance. As both companies move toward potential public listings, greater financial transparency could offer the clearest picture yet of how this rivalry is actually shaping up — and which company is best positioned to lead the next phase of the AI race.
