ITA ETF Hits All-Time High on $1.5T Defense Budget

The ITA ETF hit all-time highs as Trump's $1.5 trillion FY2027 defense budget and Iran conflict transform geopolitical risk into contractor revenue.

Lead

The iShares U.S. Aerospace & Defense ETF (ITA) surged to fresh all-time highs in 2026, propelled by the White House's proposed $1.5 trillion Department of Defense budget for fiscal year 2027 - a 44% single-year increase and the largest military spending plan since World War II - layered on top of an active conflict with Iran that has disrupted global energy shipping through the Strait of Hormuz since late February. Lockheed Martin (LMT), RTX Corp. (RTX), GE Aerospace (GE), and Boeing (BA) have been the primary beneficiaries as geopolitical risk converts directly into defense contractor order flow across munitions, missile defense, and surveillance platforms.

What Drove the ITA ETF to Record Territory?

The convergence of two structural demand drivers - an unprecedented domestic defense budget and an ongoing kinetic conflict - proved sufficient to push the ITA ETF 68% higher over the past twelve months. The White House released its FY2027 budget request in April 2026, proposing $1.15 trillion in discretionary spending plus $350 billion in mandatory resources, totaling $1.5 trillion across all defense appropriations. Administration officials characterized the proposal as a response to what the White House described as "dangerous times," as U.S. forces simultaneously maintained active operations in and around the Strait of Hormuz. The ITA ETF reached its most recent intraday record high in early July 2026, with the broader S&P 500 Aerospace & Defense sub-index trading at roughly 32 times 12-month forward earnings - a premium of approximately 60% above the S&P 500's blended multiple of around 20 times.

The FY2027 Budget: Scope and Scale

The proposed $1.5 trillion FY2027 defense appropriation represents a marked departure from prior budget trajectories. The 44% increase would exceed even the Reagan-era defense build-up of the 1980s. The allocation builds on the record $1 trillion appropriated for FY2026 and includes a 7% pay increase for enlisted personnel ranked E-5 and below. For the major aerospace and defense primes, the budget translates into expanded procurement windows, accelerated program schedules, and elevated contract ceilings across platforms ranging from tactical aircraft to missile defense systems - each representing multi-year revenue commitments embedded in the government contracting cycle.

Why Did Lockheed Martin and RTX Lead Sector Gains?

RTX Corp. has led the peer group in year-to-date performance with a gain of 14% to approximately $208.84, while Lockheed Martin (LMT) has advanced roughly 30% in 2026, with the stock trading near $532.95 as of early September against a 52-week range of $437.25 to $692.00. GE Aerospace has added 11% year-to-date, reaching $341.19. Boeing lagged the sector with a 3% year-to-date decline in its overall shares, with commercial aviation headwinds offsetting gains in its defense segment. Lockheed's outperformance reflects its exposure to the F-35 program - the largest single defense procurement in history, contracted through the 2060s - combined with the fact that approximately 72% of the company's $75 billion in 2025 revenue was sourced from U.S. military contracts. RTX's gains were amplified by its dominant position in air defense systems and precision-guided munitions, both in elevated demand given active consumption in the Iran theater.

Iran, the Strait of Hormuz, and the Order Flow Equation

The military conflict with Iran, which began with U.S. and Israeli strikes on February 28, 2026, accelerated the demand picture for defense contractors in ways the budget cycle alone could not. Iranian Revolutionary Guard Corps units blocked the Strait of Hormuz - through which approximately 25% of the world's maritime crude oil trade and 19% of global liquefied natural gas transits annually - triggering energy price volatility and elevated allied threat assessments. A U.S. aerial campaign targeting Iranian coastal radar installations, command networks, and small-boat capabilities began March 19, 2026 to reopen the waterway. The sustained operational tempo has driven accelerated restocking of precision munitions, increased demand for intelligence, surveillance, and reconnaissance platforms, and expanded maintenance and overhaul contracts - all near-term revenue contributors to the prime contractor base.

Geopolitical Risk as a Structural Tailwind

The broader global context compounds the domestic budget dynamic. NATO member defense spending reached record levels in 2026, contributing to what market participants describe as a synchronized global rearmament cycle. Global defense expenditure reached $2.63 trillion in 2025, up from $2.48 trillion in 2024, with the trajectory pointing higher as governments across Europe, the Indo-Pacific, and the Middle East recalibrate force requirements. The S&P 500 Aerospace & Defense sub-index's premium multiple reflects investor expectations that the current demand environment extends well beyond a single budget cycle.

Outlook

The ITA ETF's advance to record territory captures a convergence of fiscal policy, active military operations, and allied rearmament that sector watchers regard as structural rather than cyclical. Lockheed Martin's contract backlog, RTX's munitions and air defense exposure, and GE Aerospace's engine franchise position the sector's largest primes to translate the $1.5 trillion FY2027 request - subject to congressional approval via the National Defense Authorization Act - into multi-year revenue visibility. The Strait of Hormuz situation remains the key near-term variable: an extended blockage or broadening of the conflict would further accelerate defense demand, while a negotiated resolution could ease the threat premium embedded in sector multiples without materially altering the structural budget trajectory already locked into appropriations planning.
