Securitize, the NYSE-listed tokenization platform behind BlackRock's BUIDL fund, has signed a definitive agreement to acquire River One, a New York startup that builds warehouse financing for loan originators. Terms were not disclosed.

River One was founded in 2025 and incubated by Framework Ventures, with backing from Framework and Maple Finance. Its platform handles AI-based underwriting, facility setup, collateral monitoring and funding operations, and is built to connect stablecoin capital with traditional lending markets.

The deal moves Securitize, which held about $5B in tokenized AUM as of September, from issuing and servicing tokenized assets into asset-backed lending, a $6T private market that KKR expects to reach $9.2T by 2029.

The acquisition is expected to close in Q4 2026, subject to customary conditions.
