OpenAI

You don’t open a browser. You don’t scroll through product pages. You don’t compare prices across twelve tabs. You tell your AI what you need, and it pulls out your credit card. That scenario went from hypothetical to real last week when Visa announced it has embedded its entire payment network inside ChatGPT. OpenAI’s AI agents can now independently shop for products and complete transactions on your behalf — across 175 million merchant locations worldwide. ...

The AI industry just had one of its most revealing weeks — not because of any single announcement, but because three companies made moves that expose where this market is actually heading. Anthropic launched Claude Fable 5 at premium prices with built-in safety classifiers. Google slashed its AI subscription to $5/month. OpenAI acquired a cloud infrastructure company to make its coding agents run for days without stopping. Three different bets. One clear signal: the AI market is fracturing into tiers, and the gap between “good enough” and “best available” is becoming a strategic decision that actually matters. ...

The AI industry just crossed a Rubicon. OpenAI — the company that kicked off the generative AI revolution with ChatGPT — has confidentially filed an S-1 with the SEC. One week after Anthropic filed its own IPO paperwork. With SpaceX also preparing a debut at $1.75 trillion. Combined IPO pipeline: $3.6 trillion. We haven’t seen anything like this since the dot-com era. Arguably, we’ve never seen it at all. From Nonprofit Lab to $852 Billion OpenAI’s trajectory borders on absurd. Founded as a nonprofit in 2015, it released ChatGPT in late 2022 and changed everything. Converted to for-profit. Amassed hundreds of millions of users. Closed a $122 billion funding round in March 2026 — the largest in Silicon Valley history — at roughly $852 billion. ...

For nearly eight decades, the sharpest mathematical minds on the planet stared at a deceptively simple geometry puzzle and came up empty. Then an AI chatbot cracked it in two weeks. On May 20, OpenAI announced that one of its internal reasoning models had autonomously disproved a famous conjecture posed by legendary Hungarian mathematician Paul Erdős in 1946. The result has been independently verified by a panel including Fields medalist Tim Gowers — and it’s being called the first time AI has independently solved a prominent open problem in active mathematical research. ...

OpenAI just crossed a line nobody can un-cross. On Friday, the company launched personal finance tools inside ChatGPT that let users connect their actual bank accounts, credit cards, and investment portfolios. The AI can now see your balances, transactions, spending habits, and debts — then serve up personalized financial advice based on your real numbers. It’s either the most useful AI feature ever shipped, or a privacy nightmare waiting to happen. Probably both. ...

The biggest AI IPO of 2026 prices tomorrow — and it’s not OpenAI or Anthropic. It’s a company that builds chips the size of dinner plates. Cerebras Systems debuts on Nasdaq May 14 under ticker CBRS, targeting $150–$160 per share, $4.8 billion in gross proceeds, and a fully diluted valuation approaching $48.8 billion. The book is reportedly 20x oversubscribed. For a company with fewer than 800 employees valued at $8 billion just seven months ago, this isn’t a listing. It’s a coronation. ...

The most important AI trial in history just detonated. Ilya Sutskever — OpenAI co-founder, former chief scientist, and one of the most respected minds in artificial intelligence — took the stand in an Oakland courtroom on Monday and delivered sworn testimony that should make every OpenAI investor lose sleep. He spent a year building a 52-page dossier documenting what he called Sam Altman’s “consistent pattern of lying.” Not rumors. Not anonymous tips. Sworn testimony from the man who helped build the technology behind ChatGPT. ...

Follow the Money in a Circle Nvidia crossed $40 billion in equity investments in 2026. The biggest chunks: $30 billion into OpenAI, $3.2 billion into Corning, $2.1 billion into IREN. Here’s the pattern that has people uncomfortable: Nvidia invests in a company. That company buys Nvidia GPUs. Nvidia books the revenue. Money out, GPUs out, money back in. Rinse and repeat at scale. The Bloomberg Investigation Bloomberg’s investigative team started pulling the thread in April. What they found isn’t illegal. But it raises questions that Nvidia’s 35x forward earnings multiple probably can’t absorb. ...

Remember when OpenAI was the scrappy nonprofit promising to build AI for the benefit of humanity? Humanity now comes with a $3-to-$5 cost-per-click price tag. On May 5, OpenAI opened its self-serve Ads Manager to all US advertisers. No more $50,000 minimums. No more hand-picked brand partners. Any business can now sign up, upload creative, set budgets, and start running CPC campaigns inside ChatGPT conversations. Three months from closed pilot to open platform. That’s not cautious experimentation — that’s a land grab. ...

Two rival AI labs. Same strategy. Same day. This isn’t a coincidence — it’s a declaration of war on a $700 billion industry. On May 4th, Anthropic announced a $1.5 billion joint venture with Blackstone, Hellman & Friedman, and Goldman Sachs to embed its engineers and Claude directly into enterprise operations. Hours earlier, Bloomberg reported OpenAI is finalizing a nearly identical play: a $10 billion venture called “The Development Company,” backed by TPG, Brookfield, Bain Capital, and 16 other investors. ...
