The SpaceX IPO hype is not just about one company; it is reshaping attention and capital around space and AI, and that can create both openings and pressure points for other stocks. With a US$75 billion offer for 5% of the company and a US$1.75 trillion valuation tied closely to its xAI ambitions, investors are suddenly rethinking which companies might lose out as money and headlines gravitate toward this new listing. This article highlights 3 stocks exposed to that news, each at risk of being squeezed rather than helped by the SpaceX spotlight.

Wall Street's queuing for one rocket. While SpaceX counts down to its IPO, other companies tied to the new space race are already in orbit. → 20 Compelling Space Companies watchlist · Global Space Race Investing Ideas screener · Scan the sector by valuation on Rocket Lab's valuation page.

Lockheed Martin (LMT)

Overview: Lockheed Martin is a large US-based aerospace and defense contractor that designs and builds fighter jets, missiles, helicopters, satellites, and space systems for the US government and allied militaries around the world.

Operations: The company generates most of its US$84.1b in revenue from Aeronautics (US$30.5b), Rotary and Mission Systems (US$19.4b), Missiles and Fire Control (US$15.7b), and Space (US$13.6b), with the United States contributing US$53.0b of total sales.

Market Cap: US$120.8b

Investors looking at Lockheed Martin now have to weigh a crowded, lower growth defense story against a highly capitalised rival in SpaceX, whose US$1.75t valuation and xAI focus risk drawing capital and talent away from traditional space contractors. Lockheed Martin still offers a 2.65% dividend yield, a large backlog and new facilities aimed at expanding missile and interceptor production, but margins are under pressure, earnings have recently weakened and the business carries high debt that flattens its very high projected ROE. With the stock trading below some estimates of fair value and analysts expecting only moderate revenue growth, the key question is whether the combination of cost overruns, budget uncertainty and rising commercial space competition justifies that discount.

Lockheed Martin’s stalled margins, high debt and pressure from a US$1.75t rival could mean the real story is not the dividend. Instead, it is the risk profile buried in the 5 key rewards and 1 important warning sign

Northrop Grumman (NOC)

Overview: Northrop Grumman is a large US-based aerospace and defense technology company that builds crewed and uncrewed aircraft, missiles and weapons systems, sensors and communications gear, and a wide range of satellites and space hardware for the US government and allied nations.

Operations: The company generates most of its revenue from Aeronautics Systems (US$13.5b), Mission Systems (US$12.6b), Space Systems (US$10.7b) and Defense Systems (US$8.1b), with the United States contributing US$36.4b of total sales.

Market Cap: US$77.3b

Northrop Grumman sits at the center of defense themes investors follow, from stealth bombers and missile defense to drones and space. The stock has lagged the sector and now faces a crowded narrative as SpaceX’s US$1.75t AI and space pitch attracts attention and capital toward commercial rivals. Earnings, margins and return on equity appear strong, and the backlog around programs like B-21 and Sentinel provides a degree of visibility. However, heavy reliance on a handful of large US contracts, high debt and rising capex leave limited room for execution slip ups or budget shocks. With analysts expressing differing views on potential upside and new space competitors pursuing government dollars, investors need to determine whether this is a mispriced leader or a mature contractor that could be pressured by the SpaceX IPO spotlight.

Boeing (BA)

Overview: Boeing is a global aerospace company that designs, builds and services commercial jetliners, military aircraft, satellites, missile defense systems and space launch and human spaceflight hardware for airlines and governments worldwide.

Operations: Boeing generates most of its US$92.2b in revenue from Commercial Airplanes (US$42.6b), Defense, Space & Security (US$28.5b) and Global Services (US$21.2b).

Market Cap: US$169.8b

Boeing is attracting attention because its large aircraft and services backlog, fresh China orders and progress on 737 and 777X milestones sit alongside a very high P/E, a heavy debt load and a business that only recently returned to profitability. At the same time, SpaceX’s US$1.75t AI and space profile may be drawing investor focus and government space work away from traditional contractors. The earnings growth forecasts and recovery narrative depend on smoother production, a cleaner safety record and stable financing. However, the balance sheet still carries sizeable liabilities and cash flow has work to do. For anyone considering the recovery story, an important question is whether the risk profile is being underestimated just as a new space rival gains fresh capital and attention.

Boeing’s recovery story, high P/E and heavy debt can appear to be finally aligning, but the real tension lies in the expectations. Before that tightrope snaps, read the analysis report for Boeing
