TNB Tech Minute: Meta’s Stock Soars as New AI Agent Gathers Steam

In short

A Wall Street Journal “TNB Tech Minute” covering tech and AI news. Meta stock rose about 12% as its new AI assistant Muse gained traction: launched two weeks earlier, hit #1 on Apple’s App Store, and received strong praise on X; one analyst estimates Muse could add $28.5B by 2030. Muse is free but has paid tiers ($20/month and $100/month). OpenAI urged the US to lead global AI safety standards, including evaluation measures for self-improving systems and secure threat-sharing channels. Accenture shares rose 2.5% after it will embed evaluators at Anthropic; Accenture acquired Faculty (UK AI firm) to lead the effort, with both Accenture and Anthropic planning ~$1B each over five years.

0:35I'm Julie Chang for The Wall Street Journal. Meta stock is up about 12%. The rise comes as its personal AI assistant, Muse, is seeing early signs of success. Released two weeks ago, the app reached the number one spot in Apple's App Store and has been seeing strong user praise on X. A truest analyst noted Muse could add an additional$28.5 billion for the company by 2030. While Muse is free to use, it also offers two paid tiers for superusers, one for$20 a month and another for$100 a month. OpenAI is asking the US government to lead an effort with other countries to establish global safety and security standards for building cutting-edge AI systems.

1:20In a proposal published today, the company suggested that countries set common measures for evaluating forthcoming self-improving AI systems and establish secure channels to share emerging threats. This comes as top tech leaders recently advocated for industry-wide coordination to slow AI development. But the Trump administration has resisted those calls, with Trump stating law enforcement bodies can intervene if necessary. News Corp, owner of The Wall Street Journal, has a content licensing partnership with OpenAI. And Accenture shares are up over 2.5 % following news that it'll embed evaluators at Anthropic to stress test AI models.

1:59The initiative will be led by Faculty, a UK AI firm Accenture acquired this year. Accenture and Anthropic said they expect to invest about$1 billion each over the next five years in the AI safety effort. Anthropic called the partnership a key step in pacing technology development. Despite Monday's gain, Accenture shares remained down about 30 % this year amid weak IT spending and fears that AI could disrupt professional services. The company recently cut its fiscal year revenue guidance. For a deeper dive into what's happening in tech, check out Tuesday's Tech News Briefing podcast.
