Editors' summary

Anthropic's valuation passes OpenAI's, and Musk's claims are thrown out

On 28 May, Anthropic raised $65 billion in its Series H at a $965 billion valuation, passing OpenAI. It released Claude Opus 4.8 the same day, saying missed defects in code had fallen to a quarter of their previous rate.

On the 19th, Google announced Gemini Omni and Gemini 3.5 at I/O 2026.

On the 18th, a jury rejected all of Musk's claims against OpenAI, closing a case filed in February 2024.

Job titles were moving too. "Forward deployed engineer" — Palantir's name for engineers embedded at customer sites to see AI deployments through — had spread to the AI labs' hiring. Originally it meant someone who tailored their company's AI product for a customer and fed the lessons back into the product, but as the word spread its meaning wandered: some read it as an engineer a rung below, kept away from core development, others — stretching the term — as an all-purpose AI-savvy builder of whatever the customer wants. In Japan the word had been circulating on developer blogs since late 2025, and by now it had grown into a wave of media coverage and job listings, cast as a way for engineers to make a living in the AI era.

    Jury rejects all claims in Musk's lawsuit against OpenAI

    In Elon Musk's lawsuit accusing OpenAI and Sam Altman of betraying the organization's nonprofit mission, a federal jury in Oakland, California, unanimously rejected all of Musk's claims, finding they fell outside a three-year statute of limitations. Deliberations took less than two hours after 11 days of trial. The advisory jury's verdict was immediately adopted by Judge Yvonne Gonzalez Rogers. The core question of whether OpenAI had betrayed its founding mission went unanswered, with the case decided on procedural grounds, and Musk's side said it would appeal to the Ninth Circuit Court of Appeals.

    Google I/O 2026 introduces Gemini Omni and Gemini 3.5

    At Google I/O 2026, Google announced Gemini Omni and the Gemini 3.5 series. Gemini Omni was presented as a model able to produce output in any modality from any input, starting with Gemini Omni Flash for video generation and editing, available in the Gemini app from the day of the announcement, and described as a substantial step forward in world understanding, multimodality, and editing. Gemini 3.5 Flash was the first of a new family combining frontier intelligence with the ability to act, positioned to handle multimodal reasoning quickly and cheaply without always paying for the largest model. The announcement moved past treating text, image, video, and audio as separate products toward a single model indifferent to the form of its input and output.

    Anthropic raises $65 billion at $965 billion, passing OpenAI

    Anthropic announced a $65 billion Series H at a $965 billion post-money valuation, led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital and co-led by Capital Group, Coatue, D1 Capital Partners, GIC, ICONIQ, and XN. It included $15 billion of previously committed hyperscaler money, $5 billion of it from Amazon. The valuation had more than doubled from the $380 billion of February's Series G in barely three months, putting Anthropic ahead of OpenAI — last valued at $852 billion in March — as the world's most valuable startup. Run-rate revenue had crossed $47 billion earlier in May. The company said the funds would advance safety and interpretability research, expand compute to meet demand for Claude, and scale its products and partnerships, and it disclosed infrastructure partnerships with Micron, Samsung, and SK hynix plus compute agreements with Amazon (five gigawatts), Google and Broadcom (five gigawatts of TPU capacity), and SpaceX (GPU access).

    Claude Opus 4.8 misses four times fewer code flaws

    Anthropic released Claude Opus 4.8, improving on Opus 4.7 across coding, agentic skills, reasoning, and knowledge work, and reporting it was roughly four times less likely to overlook a flaw in code. It also cited better "honesty," flagging uncertainty rather than making unsupported claims. It scored 84% on the Online-Mind2Web web-navigation benchmark and became the first model to exceed 10% on a legal agent benchmark's all-pass standard. Claude Code gained dynamic workflows for large-scale problems, and claude.ai gained effort control for dialing computational intensity. Pricing matched Opus 4.7 at $5 and $25 per million tokens, with a 2.5x fast mode at $10 and $50 — a third the price of fast mode on previous models. Anthropic announced its Series H the same day.
