OpenAI picked a new vertical as the BIS warns on the AI boom

OpenAI picked a new vertical, the bank for central banks picked a fight with the AI capex boom, and Wall Street is bracing for the biggest IPO window in years. Three stories, one theme: AI and money are now the same conversation.

OpenAI has launched ChatGPT for Financial Services, a tailored ChatGPT Work edition that pairs built-in premium financial data with GPT-6 Astra's reasoning. Built with design partners Morgan Stanley and Evercore, it starts where the pain is sharpest: investment banking and equity research. OpenAI hosts and indexes datasets from Daloopa, PitchBook, and LSEG News on its own infrastructure — no separate data contracts or connector setup — and adds granular citations so a banker can trace any figure back to the underlying table or passage. Firms keep their existing S&P Capital IQ, MSCI, Dow Jones Factiva, and Moody's subscriptions through shared sign-in, publish their own Excel, Word, and PowerPoint templates, and turn analysis into valuation models and pitchbooks in house style. On OfficeQA Pro, a benchmark built on US Treasury bulletins with dense financial tables, GPT-6 Astra scores 69.9% against 60.2% for GPT-5.6 Sol. The hosted-data-plus-citations design is the real story: verifiability is what kept finance teams skeptical of chatbots, and OpenAI is attacking that blocker directly. The company keeps verticalizing ChatGPT — hours ago it gave the product away to US public servants, as we covered in OpenAI gives 23 million US public servants ChatGPT at $0.

The Bank for International Settlements warns the AI investment boom is accumulating financial-stability risk. In its annual economic report, the BIS — the umbrella institution for the world's central banks — flags a widening gap between AI capital spending and the cash flows meant to fund it, bridged increasingly by debt and concentrated financing: the recipe that turned past investment booms into busts. Its leadership called out the new risks directly this week. The timing is pointed — the warning lands just as public markets prepare to price AI companies at record valuations.

Anthropic's IPO filing has analysts expecting a wave of AI listings to break within the next two months. Bloomberg reports a cluster of AI-driven IPOs is expected to accompany Anthropic's debut, with the company reportedly aiming to raise around $100 billion in what would rank among the largest offerings ever. The window matters for the whole sector: labs burning capital on compute need exits, and public-market appetite for AI is the euphoria side of the same coin the BIS is warning about.

What to watch: whether Wall Street actually adopts ChatGPT for client work — and whether the BIS's rhetoric moves regulators before the IPO window opens.

Akhetonics says its all-optical CPU reaches a customer in 2026

Light-based computing keeps promising more than it delivers — but one Munich startup has just put a date on its bet, and the interview laying it out is doing the rounds on Hacker News this week. Akhetonics says it will deploy its first commercial machine with a major customer by the end of 2026, with several more planned for 2027. The company, founded by Michael Kissner and Leonardo Del Bino, is building a computer where data enters as light, is switched as light, and circulates through memory

The Week in AI — October 5–11, 2026

Every big claim this week turned out to rest on fine print more interesting than the headline: revenue only the company reporting it can define, safety tests sandboxed while the product keeps the web, and a Pentagon phase-out nobody would confirm until reporters kept asking. The week's top 5 1. OpenAI's revenue was $20 billion below the numbers everyone quoted — and the gap was definitional. The Financial Times reported Thursday that OpenAI's annualized revenue runs roughly $20 billion unde

Drone strike shuts a third Yandex data center, taking YandexGPT offline

Russia's largest tech company is learning what the AI era's infrastructure war looks like from the receiving end — three data centers in four days, and with them much of the cloud layer Russian businesses run on. A Ukrainian drone strike knocked out Yandex's data center in Vladimir early Sunday morning, the third of the company's facilities hit since October 8. The site — reported at roughly 50 MW and designed for about 2,880 server racks — stopped operating completely after the attack, Yandex

Agent teams cost up to 5x more, barely score higher

Agent teams cost up to 5x more, barely score higher

The multi-agent hype train hit a benchmark this weekend — and the grid and the trucking regulators had quiet weeks of their own. Vals AI put agent teams head-to-head with single agents on its Vibe Code Bench, and the teams cost between 1.8 and 5.1 times more for almost no extra quality. The evals company ran GPT-6 Sol and Claude Opus 5.5 solo and in teams across 50 apps at two reasoning efforts; out of four comparisons, only one was statistically significant — Sol at medium effort, where the t
