OpenAI files confidential S-1 on June 8 — a week after Anthropic; first-mover narrative flips, $85B burn projected by 2028

Editorial correction (June 10, 2026): Our earlier coverage of OpenAI’s confidential S-1 referenced a May 22 filing. That was pre-filing speculation by Fortune, CNBC, and Axios — OpenAI did not actually file until June 8, 2026. Anthropic’s June 1 filing was first. Both prior articles have been updated with notices pointing to this correction.

TL;DR: OpenAI confidentially filed its S-1 registration statement with the SEC on June 8, 2026 — a week after Anthropic. Source: OpenAI’s own blog post, confirmed by TechCrunch and other outlets. Status: confidential review begins; OpenAI has “not decided on timing yet” and notes the process “may be a while.” Financial backdrop: Wall Street Journal projects OpenAI burn reaching $85 billion in 2028 even with doubled sales. CFO Sarah Friar has publicly flagged data center spending sustainability concerns. Comparative state: Anthropic filed first on June 1 at $965B private valuation; OpenAI at $852B private valuation, now trailing Anthropic by 1 week and by $113B in private valuation. Structural read: the IPO race between the two labs is Anthropic-led on multiple dimensions — first to file, higher private valuation, projected first to operating profit, and (post-WWDC 2026) better consumer-distribution positioning via Siri Extensions than OpenAI now retains.

What was filed

The reporting from TechCrunch (citing OpenAI’s own blog post), HeyGoTrade, and other outlets confirms:

The correction to our earlier coverage

Our previous coverage assumed OpenAI filed on May 22, 2026 based on pre-filing reporting from Fortune, CNBC, and Axios that anticipated an imminent filing “as soon as Friday.” That reporting was credible at the time — it cited specific sources at OpenAI and the lead banks — but the actual filing did not happen on May 22. The confidential S-1 was filed on June 8, 2026.

What this changes about the broader narrative:

Both prior Pick Right articles (May 22 OpenAI, June 1 Anthropic) have been updated with prominent correction notices pointing to this article.

The financial picture from the TechCrunch coverage

TechCrunch’s June 8 article surfaces several new financial-trajectory data points worth attention:

A few of these are independently interesting:

The $85B 2028 burn projection. Even with doubled annual revenue, OpenAI is projected to spend $85B more than it earns by 2028. The implication is that public-markets investors evaluating OpenAI’s IPO will see substantial multi-year unprofitability ahead — not a near-term operating-profit story like Anthropic’s Q2 projected $559M profit.

Secondary-market $1T valuation for Anthropic. Secondary markets pricing Anthropic above the formal $965B primary-round valuation is a leading indicator that public-markets pricing could land at or above $1T. Whether that’s sustainable depends on Q3-Q4 financial trajectory and how the public S-1 reads when it lands.

The $36B chip-allocated debt deal. This is uncovered on our site and worth a separate investigation — Anthropic borrowing $36B against chip allocations is structurally different from equity raises and indicates Anthropic is using debt to lock in compute supply.

The post-WWDC competitive context

OpenAI’s June 8 filing happens to land the same day as Apple WWDC 2026, where Apple confirmed it picked Google’s Gemini over OpenAI for Siri AI. The timing makes OpenAI’s IPO narrative materially harder to tell:

OpenAI’s IPO process formally begins on a day when the company has just lost two of the three largest possible consumer-distribution surfaces (Microsoft default + Apple default) within six weeks. The public S-1 will need to address how OpenAI plans to compensate for that distribution erosion.

What it means structurally

Three reads.

1. Anthropic-OpenAI IPO race is now Anthropic-led on multiple dimensions. First-to-file, higher private valuation, projected first to operating profit, better recent consumer-distribution wedges. The narrative that dominated 2024-2025 — OpenAI as the dominant frontier AI company — has structurally inverted.

2. The $85B 2028 burn projection will shape public-markets pricing. Anthropic’s path-to-profit narrative is materially cleaner. For value-conscious public-markets investors, the OpenAI vs Anthropic IPO comparison becomes “Anthropic has visible profit ramp; OpenAI has scale advantage but ongoing $80B+ burn.” Both can be true; both can support trillion-dollar valuations; the multiple-expansion ceiling is just higher for Anthropic.

3. The “filed but not committed to timing” language matters. OpenAI’s noting that the process “may be a while” is unusual for a company that’s been speculated to IPO since 2022. It signals optionality — OpenAI may wait to see how Anthropic’s pricing lands before committing to its own roadshow. Whichever lab prices first sets the comparable for the second.

The honest caveats

Three caveats:

The May 22 / June 8 timing distinction may seem small but matters for narrative. Pick Right’s prior coverage operated on the wrong filing date for OpenAI. Other outlets did the same. The lesson for AI editorial work: pre-filing “expected as soon as Friday” reporting from credible sources isn’t equivalent to the filing itself. We’ve adjusted our coverage going forward.

The $85B 2028 burn is a WSJ projection, not an OpenAI-confirmed figure. Public-markets investors will see official figures only when the unredacted S-1 lands (estimated late summer for both labs).

Confidential filings can be amended. Both Anthropic and OpenAI can adjust their disclosures before the public S-1 publishes. Today’s snapshot is the current state; the picture could shift.

What it changes for Pick Right readers tomorrow

If you’re a ChatGPT Plus or Pro subscriber, nothing changes operationally. If you’re following the AI investor landscape, Anthropic appears to be ahead of OpenAI on the IPO timeline — public S-1 release expected late July / early August for both, listings plausibly Q3-Q4 2026.

For broader context, see the ChatGPT review, the Claude review, the Anthropic S-1 filing coverage, the Apple WWDC 2026 article, the Microsoft Project Polaris article, and the Anthropic Series H + Opus 4.8 article for the broader IPO-pipeline and competitive-distribution thread.
