An IPO (initial public offering) for OpenAI and Anthropic is no longer a distant hypothesis: both companies confidentially filed with the SEC in June 2026. For a small business paying a monthly ChatGPT or Claude subscription, this is not just financial news. Going public changes pricing pressure, financial transparency, and vendor stability. Here is what we know, and what it concretely means for you.
In brief
- Anthropic filed its confidential IPO paperwork on June 1, 2026; OpenAI followed a week later, on June 8, 2026 (sources: CNBC, TechCrunch).
- OpenAI is valued between $852 billion and over $1 trillion; Anthropic overtook OpenAI with a $965 billion valuation after raising $65 billion.
- According to OpenAI's chief financial officer, Sarah Friar, the company will be "a public company in 2027, or sooner" (CNBC, August 19, 2026): the timeline slipped from an initial September 2026 target.
- OpenAI loses roughly $1.22 for every dollar of revenue it collects, with 2026 losses estimated at $14 billion; Anthropic, by contrast, announced its first profitable quarter in August 2026.
- For a small business, the point is not to pick a side, but to plan ahead: once public, these companies will answer to shareholders every quarter, which typically puts pressure on prices and usage terms.
Two timelines, one race to Wall Street
Anthropic and OpenAI have been running a quiet race since spring 2026. A confidential S-1 filing with the SEC (the US stock market regulator) lets a company prepare for an IPO without immediately publishing detailed financial statements.

Anthropic files its confidential S-1

Initial goal: a fall listing
Both companies eye a tight timeline, with a possible listing as early as September or October 2026 for Anthropic.
August 19, 2026
OpenAI acknowledges a slip toward 2027
CFO Sarah Friar tells employees internally that OpenAI will be public "in 2027, or sooner," citing market volatility and SpaceX's rocky post-IPO debut as reasons for caution.
It is now early September 2026, the month originally floated for a possible OpenAI debut. That deadline has passed with no IPO, which lines up with press reports of a likely delay. Nothing is officially settled: OpenAI says it is "running its own race" and has not ruled out moving faster if market conditions improve.
Why OpenAI is stalling
Three factors, widely reported by financial media (Reuters, The New York Times, CNBC), explain the slowdown:
- Losses remain very high. OpenAI posted a net loss of roughly $38.5 billion in the prior fiscal year, driven by compute infrastructure spending. In the second quarter of 2026, the company generated $6.7 billion in revenue (up 18% quarter over quarter), but keeps losing more than it takes in.
- Volatile tech markets. OpenAI's financial advisers warned that jittery markets could cool investor appetite for the stock at listing.
- The SpaceX precedent. SpaceX's share-price pullback after its own IPO has pushed OpenAI's leadership toward caution on timing.

Anthropic: a different financial trajectory
Anthropic's profile looks different. Its revenue grew from roughly $1 billion annualized at the end of 2024 to $30 billion by April 2026, a 30-fold jump in sixteen months. The company also announced, on August 13, 2026, its first profitable quarter (details in our article Anthropic turns a profit in 2026). Several financial sources mention a possible listing as early as the last quarter of 2026, though no official date has been confirmed.
OpenAI
S-1 filed June 8, 2026. Target valuation $852B to over $1T. 2026 losses estimated at $14B. Timeline slips toward 2027, without ruling out an earlier listing.
Anthropic
S-1 filed June 1, 2026. Valuation $965B after a $65B raise. First profitable quarter announced in August 2026. Listing mentioned as early as late 2026, no official date.
What this concretely means for a small business
Going public is not a neutral event for a business customer. Here are the concrete points to watch:
- More transparency. Once public, a company publishes detailed quarterly reports. A small business can then better gauge its AI vendor's financial health, something hard to do today given the lack of full public data.
- Pressure on profitability. Public shareholders typically demand a clear path to profit. That can translate into higher API prices, smaller free tiers, or renegotiated business terms, as already illustrated by the OpenAI-Cursor partnership break covered in our article OpenAI cuts off Cursor.
- Short-term stability, medium-term uncertainty. A delay to 2027 means OpenAI stays, for now, funded by patient private investors. That can postpone a sharp price hike, but does not eliminate it.
- Vendor diversification. Whether the IPO happens in 2026 or 2027, the lesson stays the same: a small business that builds critical processes on a single AI vendor is exposed to dependency risk. Keeping options open (or at least documenting a fallback) remains the best protection.
Summary comparison
| Criterion | OpenAI | Anthropic |
|---|---|---|
| Confidential S-1 filing | June 8, 2026 | June 1, 2026 |
| Valuation | $852B - $1T+ | $965B |
| Recent revenue | $6.7B in Q2 2026 | ~$30B annualized (April 2026) |
| Profitability | ~$14B in losses expected in 2026 | First profitable quarter (August 2026) |
| IPO timeline | Targets 2027, "or sooner" | Mentioned as early as late 2026 |
Measured optimism
A successful IPO would bring these vendors stable capital and more transparent governance, both reassuring for business customers over the long run. The real risk for a small business is not the stock listing itself, but having no backup plan if prices or terms change.
FAQ
Will OpenAI go public in 2026?
That now looks unlikely. CFO Sarah Friar said on August 19, 2026 that OpenAI would be public "in 2027, or sooner," leaving the door open to an earlier listing but confirming a delay from the original fall 2026 target.
Will Anthropic go public before OpenAI?
Anthropic filed its confidential paperwork a week before OpenAI (June 1 versus June 8, 2026) and shows a stronger financial trajectory, with a first profitable quarter announced in August 2026. Several sources mention a possible listing as early as late 2026, but no official date has been confirmed.
Will an IPO push up the price of ChatGPT or Claude?
Nothing points that way in the short term, but it is a risk worth watching. Public companies typically need to show shareholders a path to profitability, which can lead to higher pricing, smaller free tiers, or changes to business usage terms.
How can a small business protect itself against changing terms from its AI vendor?
Three simple habits: avoid hard-coding critical processes directly onto a single API without an abstraction layer, regularly test a credible alternative (another model or vendor), and follow your AI vendors' official financial communications rather than discovering a price change after the fact.
Conclusion
OpenAI and Anthropic's IPO timelines remain in flux, but the trend is clear: both companies are preparing to answer to public shareholders, sooner or later. For a small business, the best approach is to track these financial signals like any other vendor risk, without panicking or ignoring the topic.
