OpenAI preps imminent IPO filing; ships ChatGPT inside PowerPoint; claims solved 80-year-old math problem

The IPO is the headline. NYP reports the prospectus could be filed confidentially as soon as Friday, with Goldman Sachs and Morgan Stanley advising — making this one of the largest tech offerings ever attempted. Weekly recap coverage notes Anthropic's KPMG win (270,000+ employees) hitting the wire at the same time, framing an IPO race where OpenAI must prove enterprise traction is keeping pace with Anthropic.

The PowerPoint integration is the most concrete product news. ChatGPT can now generate full decks from conversational prompts or raw materials (notes, images), and acts as an advanced editor that modifies or inserts slides. It is the deepest Office surface OpenAI has shipped to date and quietly reinforces the Microsoft-OpenAI commercial entanglement just as IPO mechanics start to matter for both sides. Greg Brockman, on cue, posted: 'the model alone is no longer the product.'

The ChatGPT financial preview — bank balances, transactions, and investments via account connections — pushes ChatGPT into Plaid-like territory and is the most sensitive consumer-data surface OpenAI has shipped. Expect regulatory scrutiny in parallel with the S-1.

The 80-year math claim is the most contested. OpenAI says a model produced a genuine solution to a long-standing open problem — explicitly framed to contrast with the GPT-5 'Erdős problem' episode, which turned out to be retrieval of existing literature. Researchers on HN and r/artificial (458 upvotes) are skeptical, recalling the prior embarrassment; a related 1,375-point HN thread debates whether an OpenAI model genuinely disproved a discrete-geometry conjecture or just surfaced known prior work. Resolution will depend on peer verification, not press releases.
