The Canadian province of British Columbia is preparing to sue OpenAI, alleging the US company failed to alert police after its staff internally flagged violent ChatGPT conversations linked to the person responsible for February's Tumbler Ridge mass shooting . Attorney General Niki Sharma announced Tuesday that the province has hired legal teams in British Columbia and California to "explore all legal avenues to hold OpenAI and its decision-makers accountable for its documented failure to notify law enforcement regarding explicit, flagged threats made by the perpetrator on the company's ChatGPT platform." The move stems from the February 10 attack in the remote mountain community of Tumbler Ridge, where authorities say 18-year-old Jesse Van Rootselaar killed their mother and half-brother before going to the Tumbler Ridge Secondary School and opening fire. Five children between the ages of 11 and 13 and one educator were killed at the school. Twenty-seven other people were wounded before Van Rootselaar died from what police described as a self-inflicted gunshot wound.

SpaceX's swift addition to the Nasdaq-100 index is expected to unleash billions in passive buying, as brokerages kicked off coverage of the $2 trillion rocket and satellite company with largely bullish views. The Elon Musk-led company joined the index on Tuesday, less than a month after its stock market debut on June 12 - among the fastest inclusions ever - thanks to the Nasdaq's revised rules for newly listed companies looking to enter widely tracked benchmarks. However, shares of SpaceX fell 5.4 percent, reflecting a slide in high-momentum tech stocks, including Micron Technology, on concerns about the longevity of the AI boom. "There's nervousness about expectations being too high," said Mark Hackett, chief market strategist for Nationwide. "I expect that to continue until we get some earnings out."

The United States trade deficit has jumped to $77.6bn in May on rising imports, driven by goods that include pharmaceuticals, mobile phones and semiconductors. Imports ticked up 3.3 percent from April to $395.3bn while exports fell 3.2 percent to $317.7bn, according to a report released on Tuesday by the US Department of Commerce's Bureau of Economic Analysis and the Census Bureau. The surge came amid a boom in artificial intelligence spending across the economy. Notably, semiconductor imports jumped by $1.2bn. In the oil and gas sector, petroleum imports jumped to their highest level on record despite the US-Israel war on Iran.
