Zipline, the drone delivery and logistics startup, raises new funding and expands its commercial partnership with Walmart. Multiple outlets report that Zipline closes a $1.5 billion funding round, putting the company’s valuation in the low-$20 billions, and that Walmart will add 300 drone delivery sites under an expanded deal.

The reported valuations vary slightly across coverage, with some outlets citing $21.5 billion and others $20 billion or “over $21 billion.” Outlets also note the same broad set of developments: fresh financing, increased Walmart deployment, and implications for Zipline’s scale and momentum. Bloomberg adds that the expansion follows increased demand that surprises both partners and includes CEO comments.

Other outlets focus on who is investing in the new round and the scale of Walmart’s additional footprint, while still tying the valuation directly to the funding and the expanded drone-site rollout. Overall, the reports broadly align on the funding amount, the Walmart expansion figure, and Zipline’s valuation landing in the low-$20 billions.
