Quick Summary

Global AI stocks declined on Monday following endorsements from major companies like Microsoft, OpenAI, Anthropic, and SpaceXAI to slow down the development of advanced AI models. This shift towards a more cautious approach is causing concern among investors who fear reduced spending on computing resources could stall the current investment boom in AI technology. Despite these calls for restraint, some companies continue to push ahead: Anthropic announced it expects its second consecutive profitable quarter, while OpenAI ruled out an IPO this year.

AI analysis

Story summary

AI-related stocks declined globally on Monday, following warnings from leading AI executives about the need for a slowdown in development to address safety concerns. This selloff was particularly evident among tech giants like Nvidia, which saw its shares fall by over 3%, and other chipmakers such as Micron Technology, down more than 5%. The broader Nasdaq Composite index dropped by 0.6% while the S&P 500 fell 0.5%.

The sell-off was exacerbated by Donald Trump's dismissive comments on social media, where he labeled calls for regulation of AI a "sick conspiracy" and suggested that only a strong leader could prevent misuse, implying his own leadership as sufficient guard against potential risks.

Meanwhile, the Australian sharemarket futures pointed to a 0.2% slide at the open, mirroring global trends. Despite these challenges, some non-AI-focused stocks showed resilience, such as Intuit, which gained 5.5%.
