From March 2023 to February 2026, a tracking site reports 23 deaths allegedly linked to interactions with large language model chatbots. The latest case involves a 36-year-old Florida man who, after two months of conversations with Google's Gemini and believing it to be his AI wife, died by suicide, while separate incidents in South Korea and the U.S. also reportedly involved advice or prompts from AI tools.

Cardano Foundation CEO Frederik Gregaard has warned that a critical infrastructure gap exists around accountability for autonomous AI agents as they become more widely used. He argues that organizations must be able to clearly identify who authorized an AI action, what constraints were set, and where responsibility lies when serious mistakes occur. At the same time, Cardano's ADA has been integrated into DFX.swiss via the Open Crypto Pay standard, enabling users to pay with ADA in 137 SPAR stores across Switzerland.

On Thursday, China unveiled a five-year technology roadmap that repeatedly emphasizes artificial intelligence, quantum computing, robots, and domestic chip progress as it seeks breakthroughs in core technologies. At the same time, conflict around the Strait of Hormuz and the Red Sea is jeopardizing Gulf data centers and submarine cables that U.S. tech giants have heavily funded, while the U.S. also faces mounting political pressure over rising electricity costs linked to AI-driven power demand. The White House has pushed major tech firms to pledge new generation and grid investments, but past price increases and the Iran conflict raise doubts about whether consumer energy bills can be contained.

On March 5, 2026, Broadcom shares climbed roughly 7% in premarket trading after CEO Hock Tan said the company expects AI chip revenue to surpass $100 billion in 2027. The outlook followed a record fiscal Q1 2026, with $19.3 billion in total revenue and AI semiconductor sales more than doubling year-over-year. AVGO traded around $340.60 in the premarket session, supported by a fresh $10 billion share repurchase plan and strong custom AI chip demand from major technology clients.

On March 5 2026, SEC Chairman Paul S. Atkins set out a plan to deploy artificial intelligence across the Commission’s operations to enhance anomaly detection and risk assessment. The SEC is using algorithms to spot market misconduct and misleading corporate statements, while also targeting AI washing and alleged misuse of AI in fraud schemes. Human review and due process will remain central to enforcement decisions, and the agency has already settled charges against two advisers over false AI-related claims.

On Wednesday, Amazon, Google, Meta, Microsoft, OpenAI, Oracle and xAI signed a non-binding White House pledge to cover the energy needs of their AI data centers without shifting costs to consumers. US President Donald Trump said data centers "need some PR help" and claimed the agreement aims to ease public concern that new facilities will raise electricity bills as AI-related power demand grows toward 2028.

Speaking at the Morgan Stanley Technology, Media & Telecom Conference on March 5 2026, Nvidia CEO Jensen Huang said the company's $30 billion investment in OpenAI could be its final large commitment ahead of a potential OpenAI IPO later this year. Huang also indicated Nvidia is unlikely to proceed with a previously discussed $100 billion infrastructure plan or expand its $10 billion stake in Anthropic, while OpenAI CEO Sam Altman is facing user backlash and revising Pentagon contract terms over military use of its AI tools.

On March 5, 2026, Anthropic reported that its annual revenue has climbed beyond $19 billion, more than doubling from a $9 billion run rate late last year, driven by greater usage of its AI models and tools such as Claude Code. On the same day, the Information Technology Industry Council sent a letter to U.S. Defense Secretary Pete Hegseth warning that a prospective supply chain risk designation arising from a procurement dispute could curb federal access to leading American tech services. The policy clash follows a recent decision by President Donald Trump to order a federal agency‑wide ban on Anthropic with a six‑month phaseout and comes as the company, now valued at about $380 billion, signs a three‑year AI cooperation MoU with the Rwandan government in Kigali.
