U.S. equities traded higher on Monday after President Donald Trump offered investors hope that an end to the war against Iran is drawing near.

The Dow Jones Industrial Average added 406 points, or 0.9%. The S&P 500 and Nasdaq Composite were up 0.8% and 0.7%, respectively.

“The United States of America is in serious discussions with A NEW, AND MORE REASONABLE, REGIME to end our Military Operations in Iran,” Trump said in a post on Truth Social on Monday.

However, while the president added that “great progress has been made,” he also said that if a peace deal is not reached “shortly” and the Strait of Hormuz is not “immediately” reopened, the U.S. will “conclude our lovely ‘stay’ in Iran by blowing up and completely obliterating all of their Electric Generating Plants, Oil Wells and Kharg Island (and possibly all desalinization plants!), which we have purposefully not yet ‘touched.’”

Sigma Lithium Corporation signed two offtake agreements totaling $146 million to supply high-grade premium lithium oxide concentrate, according to a press release statement issued Monday.

The company secured a $96 million prepayment agreement for 70,500 tonnes to be delivered in 2026, with monthly disbursements of $8 million. A second agreement provides for a $50 million prepayment to supply 40,000 tonnes annually for three years starting in 2026. The stock jumped 25% on the news, extending a six-month rally of 63%, though shares remain down 21% year-to-date.
