A small group of unauthorized ​users has gained access to Anthropic's new Mythos AI ‌model, according to a Bloomberg report which cites documentation and a person familiar with the matter. Users in a private online forum ​gained access to Mythos on the same ⁠day that Anthropic first announced a ​plan to release the model to a ​limited number of companies for testing purposes, Bloomberg has reported. Anthropic has said it is investigating the report of unauthorized access, and currently has no evidence that the access is affecting any of its systems.

Deutsche Telekom is weighing a full combination with its American unit T-Mobile US that could result in the largest ​public M&A deal on record. The German telecoms group has been in talks about creating a new holding company that would make a stock bid for shares of both Deutsche Telekom and T-Mobile. The potential transaction would create a single, simplified corporate group that controls the operations of the two companies and would be jointly owned by their current investors. Bloomberg says any such deal would require political support and may face significant obstacles, including the need for approval from the German government and state-owned lender KfW, which own a combined stake of about 28% in Deutsche Telekom.

Bank of Canada Governor Tiff Macklem has said global financial systems must “come to grips” with the risks posed by rapid advances in AI models such as Anthropic’s Mythos. “I don’t think anybody knows the full implications at this point. That’s precisely what everybody’s trying to get to the bottom of,” Macklem told reporters. He said policy-makers and financial institutions are still in “early discussions” about what Mythos means for the integrity of the global financial system.

China's commerce ministry has issued a warning about potential retaliation against European firms if the EU enforces its proposed cybersecurity regulations targeting Chinese companies such as Huawei and ZTE. In a detailed 30-page document submitted to the European Commission, the ministry said that "broad retaliation is on the table" if these firms face penalties under the draft law, which was first announced in January. “If the EU designates China as a ‘country posing cybersecurity concerns’ or lists Chinese entities as ‘high risk suppliers’ to phase out equipment manufactured by Chinese businesses in a compulsory manner and exclude Chinese products and services from the EU market, China can launch relevant investigations into the EU or EU businesses, and take reciprocal measures,” said a submission from the ministry in response to the commission’s request for feedback.

Elite law firm Sullivan & Cromwell has apologized to New York federal judge Martin Glenn for submitting a court filing with inaccurate citations and other errors generated by artificial intelligence. In a letter dated April 18, Andrew Dietderich, co-head of the firm's global restructuring group, said the filing contained multiple “hallucinations” made by AI software. Boies Schiller Flexner - which is also involved in the case - spotted the errors in the filing, Dietderich wrote in the letter to Glenn, chief judge of the U.S. ⁠Bankruptcy Court in Manhattan. "I apologize on behalf of our entire team. I also called Boies Schiller Flexner ​LLP on Friday to thank them for bringing this matter to our attention and to apologize directly to them ​as well," Dietderich wrote.

The director of the Congressional Budget Office, Phillip Swagel, has expressed confidence that the U.S. will avoid a fiscal crisis despite national debt exceeding $39tn and annual interest costs surpassing $1tn, citing past economic recoveries and faith in policymakers to act when necessary. While acknowledging the need for a more sustainable fiscal path, Swagel believes markets expect Congress to intervene before a crisis emerges, even as looming pressures such as Social Security and Medicare insolvency within the next decade may force action.

The Supreme Court has declined to hear a bid by eight major financial institutions to prevent American cities, including Baltimore, Philadelphia and San Diego, from progressing a $12bn class action accusing them of artificially inflating interest rates on a popular municipal bond. The justices turned away an appeal by the ​banks - Bank of America, ​Barclays, Citigroup, Goldman Sachs, JPMorgan Chase, Royal Bank of Canada, Wells Fargo and Morgan Stanley - that was brought after a lower court upheld a judge's decision to certify the lawsuit brought by ​the cities as a class action. The Supreme ⁠Court's action paves the way for the suit to proceed as a class action.

Supreme Court Justice Ketanji Brown Jackson has intensified her critique of the court's conservative majority for increasingly using the emergency docket, which she argues undermines the judicial process. Speaking at Yale Law School, Jackson said the practice has a "corrosive effect" on the judicial system, leading to "zombie proceedings" in lower courts. She emphasized the importance of allowing lower courts to handle cases, saying: "There is value in avoiding having the court continually touching the third rail of every divisive policy issue in American life." Jackson noted that the emergency docket, once used sparingly, has surged since 2025, often favoring conservative policies. She expressed concern that the court's current approach creates "lock-in effects" on legal issues, which can lead to real-world harms from litigation delays.

Big Four accounting firm EY is being sued by a former employee who said she was fired after a viral graduation speech against Israeli actions in Gaza. EY put Cecilia Culver on administrative leave less than 24 hours after the speech and, after she lodged a discrimination complaint, fired her four days later. In the six-minute speech in May last year, Culver claimed George Washington University was profiting from a “genocide” in Gaza, and called on the institution to “divest from the apartheid state of Israel.” The lawsuit alleges that EY fired Culver to placate an “external Zionist pressure campaign” which was organized in response to her speech. “When EY faced a choice between its legal obligation to protect its employee from discrimination and its desire to placate an organized campaign targeting her for the identity-based content of her expression, EY chose wrong,” the lawsuit says.
