Stock market today: Dow, S&P 500, Nasdaq rally as Iran deal optimism offsets Fed hike worries

Anthropic (ANTH.PVT) met with members of the Trump administration this week, as the AI lab seeks to reach an agreement that will allow it to begin using its Fable 5 and Mythos 5 models again. The administration issued an export control directive against the models last Friday, preventing Anthropic from allowing any foreign national, inside or outside the US, to access the software. And that includes Anthropic employees. Not being able to show off its latest and greatest models puts the company in a tough spot as it prepares for its initial public offering later this year. But the administration's approach could pose problems for more than just Anthropic. Shares surged Thursday in Asia, with benchmarks in Japan and South Korea setting fresh records, after the U.S. and Iran signed their initial agreement ending the war. The rally in Asia followed a retreat Wednesday on Wall Street driven by speculation the Federal Reserve may raise interest rates this year to curb inflation. In Tokyo, the Nikkei 225 (^N225) kept on surging, gaining 1.9% to 71,233.35. It topped 70,000 for the first time this week and is still gaining thanks to hopes for an end to the war and buying of high-tech shares due to the artificial intelligence boom. South Korea’s Kospi (^KS11) likewise has been setting records, gaining 0.6% to 8,917.31. Taiwan's Taiex jumped 1%. In Hong Kong, the Hang Seng (^HSI) lost 1.4% to 23,968.66, while the Shanghai Composite index edged 0.1% higher. Australia's S&P/ASX 200 (^AXJO) slipped 0.4% to 8,930.50.
