Japan is set to become the first overseas partner in the U.S. federal Genesis Mission, joining a joint plan to invest $1 billion over five years in AI-driven technology development. A formal announcement is expected in early June when officials from Japan’s education and economy ministries meet the U.S. Department of Energy.

A purported AI-powered crypto trading operation linked to Nathan Fuller is facing SEC scrutiny over claims he raised $12.3 million from investors between 2022 and 2024. The SEC alleges only 3% of the funds went to real trading, while about $6.2 million was used for personal spending and $5.5 million was paid out to earlier investors.

IREN Limited said it finalized $3.65 billion of investment-grade debt on Monday to fund NVIDIA GPU hardware for its multiyear AI cloud contract with Microsoft. The facility combines a $2.10 billion private placement and a $1.55 billion delayed-draw term loan, resulting in a blended borrowing cost of 6.00%. The financing, alongside Microsoft prepayments, covers about 96% of IREN’s $5.81 billion GPU capital spend tied to the agreement.

Anthropic, the company behind Claude, confidentially submitted a draft S-1 to the U.S. SEC on June 1, 2026, marking its first formal step toward an IPO.

The S&P 500 ended the last trading day of May at a record close, but only 20 constituents posted their own all-time highs, most tied to AI-related themes. Bank of America's Michael Hartnett compared the narrow leadership to March 2000, while May's surge was led by chipmakers such as AMD (+50%) and Micron (+85%).

New research from the AI-Driven Enterprise Institute (AIDE) evaluates how S&P 500 companies are adopting AI across four pillars and assigns scores up to 100. Nvidia, Amazon, Meta and SLB (formerly Schlumberger) earned top overall results, while Walmart, AES and NextEra Energy followed with scores in the mid-90s. The open-source index uses public signals such as earnings-call transcripts, job postings and patent filings to benchmark adoption rather than financial impact.

Intel says it plans to ship its Crescent Island data-center AI GPU in 2026, positioning it against Nvidia and AMD by focusing on lower memory costs and reduced power needs. The design uses up to 480GB of LPDDR5X and is intended for air-cooled racks, with customer sampling slated for the second half of 2026. The company also links the inference-focused chip push to demand from bitcoin miners shifting data centers toward AI compute.
