Halliburton’s stock advanced 2.7% in pre-market trading on Monday, lifting shares to $37.16, as Brent crude futures surged above $90 per barrel following overnight U.S. strikes on Iranian targets in the Strait of Hormuz.
The energy sector’s outperformance contrasted with a mixed broader market, with the S&P 500, Dow Jones and Nasdaq all trading modestly lower in pre-market futures. Halliburton, North America’s largest oilfield-services provider, has gained roughly 5% over the past two weeks and is up more than 2.7% so far in Monday’s session.
U.S. forces struck two missile launchers on Iran’s Larak Island in the Strait of Hormuz on Sunday, marking the first confirmed American strikes on Iranian territory since late July. Iranian state media reported a retaliatory strike by the Revolutionary Guards on two U.S. air bases in Jordan on Monday, escalating regional tensions and stoking concerns over potential supply disruptions in the Middle East.
Brent crude futures jumped 5.7% to $91.03 per barrel, extending gains that have kept oil prices elevated throughout 2026 amid sustained supply risks in the region. The spike in crude prices typically expands upstream capital expenditure budgets, driving increased drilling and completion activity for Halliburton’s customers.
The company’s shares had closed at $36.18 on August 28, while after-hours trading on Sunday saw a decline to $34.42, down 4.86%. The latest rally follows three consecutive days of gains for Halliburton, reflecting investor focus on the energy sector’s resilience amid geopolitical uncertainty.
