OpenAI

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. ...

A 23-year-old with no math degree typed an unsolved conjecture into ChatGPT on a Monday afternoon. Eighty minutes later, he had a valid proof that defeated professional mathematicians for sixty years. Fields Medalist Terence Tao confirmed it. The math world is losing its mind. The Kid Who Didn’t Know It Was Hard Liam Price wasn’t trying to make history. He was “vibe mathing” — his term for feeding random open problems into GPT-5.4 Pro to see what happens. He’d been doing it for months with his friend Kevin Barreto, a Cambridge undergrad, pulling unsolved conjectures from erdosproblems.com like lottery tickets. ...

The U.S. military just took its biggest step toward becoming an “AI-first fighting force.” On May 1st, the Department of Defense announced agreements with eight AI companies — SpaceX, OpenAI, Google, Nvidia, Reflection, Microsoft, AWS, and Oracle — to deploy frontier AI models on the Pentagon’s most sensitive classified networks. But the real headline? The company that’s not on the list: Anthropic. What Actually Happened The agreements give all eight companies access to deploy AI on the Pentagon’s Impact Level 6 and IL7 network environments — the most sensitive classified systems where war plans get made and intelligence gets analyzed. ...

A company founded five years ago by researchers who thought AI safety deserved more attention is now worth more than Switzerland’s GDP. Anthropic is closing a $50 billion funding round at roughly $900 billion. If that lands, the Claude maker officially leapfrogs OpenAI — the very company its founders left behind — to become the most valuable AI startup on Earth. Welcome to 2026, where turning away billion-dollar checks is a flex. ...

On Sunday, OpenAI and Microsoft announced the end of their exclusive partnership. By Monday, OpenAI’s models were live on Amazon Web Services. The speed tells you everything about how long this was in the making. This isn’t a cloud provider swap. It’s OpenAI declaring independence — while juggling missed revenue targets, an $852 billion valuation, a looming IPO, and a trial against Elon Musk happening simultaneously. What Actually Changed On April 27, OpenAI and Microsoft jointly announced a restructured deal: ...
