Trump Says U.S. Will End Israel Aid in 2027

For markets, the immediate issue is not the loss of revenue for defense companies so much as the change in how that spending is routed. Israel has long relied on U.S. military assistance to fund weapons purchases, and a switch to direct arms sales would keep demand in the U.S. defense supply chain while potentially changing contract terms, timing and financing.

The policy also lands against the backdrop of a much larger U.S. security commitment to Israel since the Gaza war began in 2023. An academic study last year estimated at least $21.7 billion in U.S. military assistance to Israel after the start of the conflict, underscoring how material the relationship has become for both countries and how sensitive any funding shift could be in Washington and Jerusalem.

Defense stocks moved sharply in recent sessions even before the latest announcement, with Lockheed Martin, RTX and Northrop Grumman all trading well above key long-term averages at various points this year before recent pullbacks. That leaves investors watching whether Trump’s proposal is mostly a headline change or the start of a broader review of U.S. foreign military financing that could affect future orders, margins and budget timing across the sector.

The bigger political risk is that a move away from grant-based aid could force Israel to absorb more of its own defense bill just as regional tensions remain elevated. Any formal shift would still need to be carried through U.S. policy and appropriations channels, making Congress, the Pentagon and Israel’s own defense planners the next focal points.
