The US president also said the draft agreement, which hasn't been confirmed, includes the reopening of the Strait of Hormuz. But Iran says Trump's claims are "incomplete and inconsistent with reality." DW has more.
Iranian state media also dismissed Trump's claim that the deal was "largely negotiated" as "incomplete and inconsistent with reality." Earlier on Saturday, Iranian Foreign Ministry spokesperson Esmail Baqaei had described the draft proposal as a "framework agreement" that would require a further "30 to 60 days" to discuss further details before a "final agreement is reached." A fifth of the world's oil and gas supplies flowed through the Strait of Hormuz before the war.
Iran effectively closed the strategic passage shortly after the US and Israel launched their joint operation against Iran in late February.
In recent weeks, Tehran and Washington have imposed reciprocal naval blockades in the Strait.
The effective closure of Hormuz has severely disrupted global energy supplies, causing oil prices to surge and stock markets to plummet.
"In addition to many other elements of the Agreement, the Strait of Hormuz will be opened," Trump said, without specifying what the deal's "other elements" entailed.
"An Agreement has been largely negotiated, subject to finalization between the United States of America, the Islamic Republic of Iran, and the various other Countries," Trump said in the social media post.
The US president said he had spoken with leaders from Saudi Arabia, the United Arab Emirates, Qatar, Egypt, Jordan and Bahrain, as well as Turkey and Pakistan. He added that he had spoken separately with Israeli Prime Minister Benjamin Netanyahu.
"Final aspects and details of the Deal are currently being discussed, and will be announced shortly," Trump said, without providing an exact timeline.
Trump's optimistic statement came hours after he had told US outlet Axios that the chance of a deal was a "solid 50/50" while threatening to blow Iran "to kingdom come" if the talks fail.
While Iran acknowledged that a "framework agreement" was in place, it warned that significant gaps still stand in the way of a permanent resolution to the conflict.
If confirmed, the deal would end a more than 12-week impasse that has seen Pakistan-mediated negotiations make little to no progress.
The US and Iran have been deadlocked since agreeing to a ceasefire in early April.
