President Donald Trump discussed efforts to de-escalate U.S.-Iran tensions with Qatari Emir Tamim bin Hamad Al Thani, according to the Gulf state’s government. Furthermore, Iran is considering allowing European nations to remove mines from Hormuz, said diplomats familiar with the matter.

“Markets are reacting to the possibility that a reopening of the Strait of Hormuz could help normalize global oil supplies and reduce near-term energy price pressures,” Tony Miano at Wells Fargo Investment Institute. “Lower oil prices can ease inflation concerns.”

The developments pushed oil prices lower, with the West Texas Intermediate futures settling down 5.69% to $75.77 per barrel. Brent crude, the international benchmark, declined 5.26% to $79.36 a barrel.

Over to earnings, Palantir’s robust revenue outlook, which surpassed estimates by a wide margin, pushed its stock price up close to 30% on Tuesday. CEO Alex Karp noted that AI demand was ‘otherworldly,’ which in turn pushed chip stocks like Micron Tech (MU) and Marvell Technology (MRVL) soaring.

While futures were flattish at the time of writing, investors were digesting after-hours earnings from Advanced Micro Devices (AMD), which somewhat disappointed investors, coupled with quarterly updates from SpaceX (SPCX).
