Global markets have seen some respite in the Iran war, after U.S. President Donald Trump announced positive discussions with Iran and stated that he is'very intent on making a deal' with them. This move is likely to raise hopes of de-escalation in the conflict, which had driven oil prices higher and fueled recession fears. Despite Iranian state media denying any discussions had taken place, this has raised questions about the durability of the market rally. The Dow Jones Industrial Average and European markets also rebounded following the announcement, with the oil prices falling sharply. OpenAI warns of potential risk to its business if its close ties with Microsoft could be a significant factor in its upcoming IPO.
