OpenAI files for US IPO after Anthropic leads AI startups to public markets

OpenAI has filed for a US initial public offering, following Anthropic's move to go public. The filings mark a watershed moment for AI companies seeking capital and legitimacy.

Our Take

Two of the three largest AI labs are now racing to the public markets, but the IPO itself proves nothing about which model or company will dominate—only that investors believe the sector warrants billion-dollar valuations.

Why it matters

IPO filings signal that AI founders believe near-term revenue and scale justify public equity valuations. For practitioners and enterprises, this shift means licensing terms, support SLAs, and long-term API pricing are about to become negotiation points rather than take-it-or-leave-it SaaS contracts.

Enterprise buyers: audit your OpenAI and Anthropic API spend and lock multi-year agreements before pricing pressure accelerates post-IPO.

Two AI labs file for public markets within months

OpenAI has filed for a US initial public offering, according to Reuters. The filing follows Anthropic's move to seek public markets earlier this year. Both moves place the two largest private AI research companies on a path to listing on major US exchanges within the next 12 to 24 months.

Reuters did not publish details of OpenAI's filing amount, timeline, or underwriters in the excerpt available. Anthropic's IPO plans were announced separately, also without disclosed financials at announcement.

The two companies have dominated private AI funding rounds and enterprise adoption over the past 18 months. OpenAI operates ChatGPT, Claude competes directly as Anthropic's flagship product. Both have captured significant share of enterprise API spend, research partnerships, and venture capital attention.

Public markets mean pricing power shifts to buyers

IPO status does not determine technical superiority or market dominance. It does determine how these companies fund themselves, report results to shareholders, and price their services. Public companies face quarterly earnings pressure, analyst expectations, and disclosure obligations that private companies avoid.

For OpenAI and Anthropic, going public means moving from private venture-backed growth at any cost to public shareholder returns. That shift typically increases pressure on unit economics, API pricing, and SLA commitments. Enterprises currently paying as-you-go for API calls should expect tiered pricing, volume discounts tied to long-term contracts, and more aggressive commercial terms.

The timing matters. AI adoption is still early; enterprise workloads remain experimental or low-volume for most customers. Public companies will need to demonstrate that their user base is either growing fast enough to justify valuations or willing to pay much more per token. Both scenarios favor enterprises that lock pricing now.

Three moves before IPO closes

First, calculate your annual OpenAI and Anthropic API spend for the past 12 months. Include all tokens, fine-tuning runs, batch jobs, and seat licenses across all teams. Get the number in writing from finance.

Second, request a meeting with your account manager at both companies before the IPO roadshow begins (typically 2-4 weeks before filing, though neither company has published a date). Propose a multi-year, fixed-price contract pegged to current volume or a small growth multiple. Offer a 10-15% prepay discount in exchange for a 24-month lock. Public companies cannot usually grant retroactive discounts on volume that has already been consumed, so this must happen before listing.

Third, audit your model dependency. If 80% of your AI spend goes to one vendor, consider running parallel workloads on the competing lab's model for 10% of your use cases. This gives you negotiating leverage and technical insurance if either company's pricing or SLA terms shift post-IPO.
