Friday closed with markets and infrastructure testing their political limits: Anthropic’s IPO path named AI backlash, bitcoin caught a bond-driven bid, Canada trade talks collapsed into tariffs, and the wars in Iran and Ukraine remained unsettled.
The U.S. was set to impose 50% tariffs on about $20 billion of Canadian products after late-night talks failed. U.S. Trade Representative Jamieson Greer blamed new Canadian demands and walk-backs, while Prime Minister Mark Carney said Washington changed terms at the last minute; the fight covered only about 5% of Canada’s exports to the U.S. but landed heavily because the two countries traded $880 billion last year.
TikTok agreed to pay $400 million to settle a Justice Department children’s privacy lawsuit that accused it of violating COPPA. The company will pay $300 million immediately and another $100 million after an older Musical.ly consent decree is vacated, closing a 2024 case just as TikTok’s U.S. arm has been reorganized around Oracle, Silver Lake, and MGX.
Federal officials ordered sharp Colorado River cuts for California, Nevada, and Arizona over the next two years, totaling 1.25 million acre-feet annually, with Mexico reducing its intake by another 250,000 acre-feet. Arizona takes the largest reduction, while the upper-basin states avoid cuts for now; the announcement came as the river basin’s current rules approach an October deadline with no long-term compact in place.
The Pentagon fired Stars and Stripes publisher Max Lederer and editor Erik Slavin, citing insubordination after the military newspaper reported on conditions aboard the USS Abraham Lincoln. Slavin said the dispute centered on editorial independence and whether censorship of news for service members would cross a red line; reporter Lara Korte said she was dismissed on similar grounds.
Iranian President Masoud Pezeshkian said it was time to end the months-long war with the United States from what he called a ‘position of power and dignity.’ The remark came as Iran and Oman’s foreign ministers spoke, Washington prepared economic sanctions, and Iran’s military leadership warned it remained ready to respond across land, sea, air, air defense, and cyberspace.
A Russian drone strike on a busy shopping center in Kryvyi Rih killed 16 people and drew a new sanctions threat from the European Union. EU foreign policy chief Kaja Kallas called the attack ‘terror by design’ and said she would put forward the bloc’s most far-reaching Russia sanctions listings since the start of the war.
Ukraine reported more Russian strikes after the Kryvyi Rih mall attack, with officials saying at least two more people were killed in Kyiv and Zaporizhzhia. The BBC verified footage of a second drone hitting the already burning shopping center; authorities said 130 people were injured, 29 seriously, and nine people, including two children, remained missing.
Guyana’s Carolyn Rodrigues Birkett led the U.N. Security Council’s second informal straw poll to choose the next secretary-general. She drew eight ‘encourage’ votes, ahead of Rebeca Grynspan and Rafael Grossi with seven each, as the council works toward a recommendation before António Guterres’s term ends December 31.
Anthropic’s expected IPO prospectus will list backlash against AI and data centers as a risk factor, according to CNBC. The company has held preliminary investor meetings and is privately valued near $1 trillion, while prospective public-market investors are weighing job-displacement fears, local opposition to data centers, and the prospect of a roughly $2 trillion float.
Bitcoin ended Friday near $76,944, up 6% on the day and 22% for the week, its best weekly run since 2023. CNBC tied the rally to falling Treasury yields after Scott Bessent’s bond-market intervention, renewed optimism around the Clarity Act, and a short squeeze that liquidated roughly $2.7 billion in crypto shorts.
Ken Griffin told Citadel clients that the firm unwound more than 80% of the aggregate risk it acquired from Alexandr Wang and Daniel Gross’s Situational Awareness hedge fund. Citadel used more than 100 block trades totaling over $4 billion in market value after buying positions from the fund, which had been forced to unload public holdings after steep losses.
Chinese regulators ordered Tesla to fix 2.98 million Model 3 and Model Y vehicles over emergency door-opening risks. The cars will need interior warning labels showing how to open rear doors after power loss, and Tesla will push a software update to lower windows automatically after a collision.
Penn State researchers showed that thunder can be used as a middle path between waiting for earthquakes and setting off artificial seismic events. Their model helps interpret complex ‘thunderquake’ signals traveling through the upper crust, and the team used it to reconstruct terrain beneath the local campus using fiber-optic seismic sensing.
Motorola’s first phones supported by GrapheneOS are now expected in 2027, expanding the privacy-focused Android project beyond Pixels. The devices will not ship with GrapheneOS preinstalled, but Motorola will support the project’s strict hardware requirements; the team says they will be premium flagships priced above current Pixels.
