Grab is buying U.S. investing app Stash for about $425 million in a major cross-border fintech move 

Grab Holdings Limited, the Singapore-based super-app operator known for ride-hailing, delivery and digital financial services across Southeast Asia, has agreed to acquire Stash Financial, Inc., a U.S.-based digital investing and financial wellness platform, in a deal valuing Stash at roughly US $425 million.

Under the terms of the agreement, Grab will initially purchase a 50.1 % controlling stake in Stash at closing, with the plan to buy out the remaining equity over the next three years at fair market value. Payment for the deal will be made using a mix of cash and stock, with the exact mix at Grab’s discretion. The transaction is expected to close in the third quarter of 2026, subject to regulatory approvals and other customary conditions.

What Stash does & why it matters

Stash is a U.S.-registered investment advisor and fintech platform that combines subscription-based investing, banking tools, financial education resources and an AI-driven Money Coach feature designed to help everyday consumers improve their financial habits and long-term wealth outcomes. It currently manages more than US $5 billion in assets and has over one million paying subscribers.

The company also offers StashWorks, an employee financial wellness programme used by U.S. employers to help staff build better saving and investing behaviours through guidance and tools.

Strategic rationale for Grab

This acquisition marks a significant expansion of Grab’s financial services footprint into the U.S. mass-market investing space – a market where it previously had no commercial presence. It adds a recurring subscription revenue engine and deepens Grab’s fintech capabilities, particularly in areas powered by AI and personalised financial guidance.

Post-closing, Stash will continue operating as an independent brand, retaining its current services, business model and leadership – including its co-founders and co-CEOs — while gaining access to Grab’s broader ecosystem and resources. Grab has also indicated it may explore introducing elements of Stash’s technology, such as the AI Money Coach, into its Southeast Asian markets over the longer term.

For Grab, this move diversifies revenue beyond its core ride-hailing and delivery businesses and bolsters its financial services roadmap – which already includes lending, payments and digital banking – at a time when the company is increasingly focused on sustainable, high-margin services.
