It followed strong market reception of Meta Platforms’ AI assistant Muse, launched earlier in the month. Oil hovered near $100 per barrel, and the 10-year Treasury yield was around 4.94 % after President Donald Trump warned at the UN that he could “annihilate the Islamic Republic” without a Middle-East deal.
