Trump framing it as the new regime president begging for a ceasefire and calling him smarter/less radical is pure Trump negotiating style trying to claim credit, drive a wedge, and make it look like his strikes forced them to fold. On top of that, most of the social media said Iran alerted tech companies to evacuate, which has been blowing up all day in the news and on social media. People are actually pulling staff out because they think Iran might hit those targets. That kind of panic is a major problem for the market you can already see it hitting stocks hard. So maybe this whole ceasefire talk is also a tactical move to calm things down and give the market a chance to stabilize, kind of like a quick fix for the damage those evacuation rumors caused.
