What

Why it matters

Open questions

• OpenAI has not held pre-IPO investor meetings as of late June [20], and reports point toward 2027 [22], but one outlet cited a December 2026 target [28] and Altman hinted at 'within next year' on June 18 [27] — what is the actual current internal timeline, and what conditions would move it?

• Did Anthropic successfully persuade the White House to lift the foreign-national access restriction on Fable 5 [16], and if not, how does that restriction affect the investor narrative at a $965B valuation? [9]

• Will S&P's GAAP profitability test treat non-cash stock-based compensation as disqualifying, or will underwriters frame OpenAI's implied ~$8B cash loss as the operative figure for prospective investors? [31][1]

• Anthropic's annualized revenue has been cited at $45B [10] and $47B [11] by different sources — what does the actual S-1 show, and has any credible source confirmed a specific listing target date?

Perspectives

Tensions

• OpenAI's leaked 2025 net GAAP loss of ~$38.5B–$39B against $13.07B in revenues directly illustrates how far OpenAI is from the GAAP profitability S&P Dow Jones requires [30][37] — the same standard passive-investor advocates defended when S&P rejected the rule changes. [1] [30][37][1][3]
• The same OpenAI financials can be read as a ~$39B GAAP loss or an ~$8B cash loss depending on whether non-cash stock compensation is included; analysts disagree on which figure is most relevant for evaluating IPO prospects and index eligibility. [31][30] [31][30][1]
• Altman hinted at a listing 'within next year' on June 18 [27] and one outlet cited a December 2026 internal target [28], but CNBC and the NYT reported on June 25–26 that OpenAI has held no pre-IPO meetings and is leaning toward 2027 — prediction market odds for a 2026 IPO fell from 71% to 29%. [20][22][26] [27][28][20][22][26]
• Some advisers reportedly recommended OpenAI delay its IPO partly because of SpaceX's post-IPO volatility [24], while SpaceX's 19% first-day gain and $85.7B in total proceeds [7][5] made it the largest IPO on record — the two framings of SpaceX's debut reflect different readings of the same market outcome. [24][7][5]
• If Q1 2026 OpenAI revenue of $5.7B [32] implies an annual run rate well above $20B, revenue is growing sharply — but revenue growth alone does not close the GAAP profitability gap S&P requires, and passive-investor advocates argued the labs' fundamentals don't support their valuations. [3][1] [32][3][1]
• Anthropic is negotiating compute access from Microsoft's Maia 200 chip [13] while its existing compute relationships with Google and Amazon are disclosed as material in SpaceX's own IPO filings [14], creating potential tension between Anthropic's multi-cloud ambitions and its existing partner commitments ahead of its IPO.
