AI News Roundup — May 18, 2026: Musk Loses OpenAI Trial, Anthropic Nears $900B, Pope's First Encyclical on AI

A packed week in AI: a landmark legal verdict, jaw-dropping valuation numbers, and a papal intervention on AI ethics.

TL;DR: A California jury rejected Elon Musk's lawsuit against OpenAI, clearing the path for what could be the biggest IPO in history. Anthropic is raising at a ~$900B valuation — nearly triple its value three months ago. Pope Leo XIV announced his first encyclical on AI, "Magnifica Humanitas," to be released May 25. Google unveiled its biggest search bar redesign in 25 years with Gemini 3.5 Flash. The EU watered down AI Act compliance deadlines. And OpenAI released three new real-time audio models for developers.

1. Elon Musk Loses OpenAI Trial — Jury Says He Sued Too Late

The biggest AI legal battle of the decade came to a decisive end on Monday. A jury in Oakland, California took less than two hours to reject Elon Musk's claims against OpenAI, Sam Altman, and Microsoft, finding that Musk waited too long to sue under the statute of limitations.

Musk co-founded OpenAI in 2015 as a nonprofit but left in 2018 after a power struggle. He sued in 2024, arguing the company abandoned its humanitarian mission by creating a for-profit arm and taking billions from Microsoft. He sought over $150B in damages and Altman's removal from the board.

Instead, the verdict removes what Business Insider called a "$134 billion overhang" on OpenAI's operations — clearing the way for what could be the largest IPO in history later this year. OpenAI is currently valued at approximately $730-852 billion.

During the trial, Altman testified that Musk made "hair-raising" demands for total control of the company, telling the court: "Part of the reason we started OpenAI was that we didn't think AGI should be under the control of one person, no matter how good their intents are."

Why it matters: The verdict doesn't just settle a legal dispute — it defines the legal framework around AI company restructurings going forward. The "statute of limitations" ruling means challenges to AI corporate governance may need to be brought much faster. Meanwhile, OpenAI can now focus entirely on its IPO, which will be closely watched as a bellwether for the entire AI industry's financial maturity.

2. Anthropic Nears $900 Billion Valuation in Mega-Round

While OpenAI won in court, its San Francisco rival Anthropic made headlines on the fundraising front. The company is weighing a funding round of $30-50 billion at a valuation of $850-900 billion, according to Financial Times and Bloomberg reporting.

That's nearly triple its valuation from just three months ago. The round is reportedly co-led by Dragoneer, Greenoaks, Sequoia, and Altimeter — notably, no tech giants are involved, which may signal a strategic move to maintain independence.

The fundraising race between Anthropic and OpenAI is now playing out on multiple fronts: talent acquisition, enterprise customers, and a race to go public first. Anthropic CEO Dario Amodei recently stated the company plans to "acquire as much compute as we can," underscoring the capital-intensive nature of frontier AI development.

Why it matters: A $900B valuation for a company that didn't exist five years ago is staggering. It signals that investors see AI model companies not just as tech plays but as infrastructure-layer bets on par with cloud providers and search engines. The absence of big-tech investors in this round also suggests Anthropic is betting on its independence as a differentiator.

3. Pope Leo XIV to Issue First Encyclical on AI: "Magnifica Humanitas"

In a remarkable development at the intersection of faith and technology, Pope Leo XIV announced his first encyclical — one of the highest forms of papal teaching — addressing the rise of artificial intelligence. Titled "Magnifica Humanitas" (Magnificent Humanity), it will be released on May 25, the 135th anniversary of Pope Leo XIII's landmark encyclical on labor rights.

Notably, the Pope will present the document personally — a break from tradition — and will be joined by Chris Olah, co-founder of Anthropic. The encyclical's theme is "the protection of the human person in the age of artificial intelligence."

Key expected content includes:

A condemnation of AI use in warfare, continuing the Pope's recent warnings about the "inhumane evolution of the relationship between war and new technologies"
A renewed framework for workers' rights in the age of automation — the Church's fullest guidance on labor in decades
A call for AI development to respect human dignity and guard against concentration of power

The involvement of Anthropic's co-founder is particularly striking given the company's ongoing clashes with the Trump administration over guardrails restricting military uses of AI.

Why it matters: With 1.4 billion Catholics worldwide and Pope Leo's growing influence as a moral voice on technology, this encyclical could shape the global conversation around AI regulation, particularly in the Global South. It also signals that AI ethics is no longer a niche concern — it's becoming a mainstream moral issue on par with climate change and inequality.
