Larry Fink doesn’t do pilot programs anymore.

On Tuesday, the CEO of the world’s largest asset manager—$13.46 trillion in AUM—told Wall Street that BlackRock is building proprietary tokenization technology to rebuild capital markets on-chain.

“We need to be tokenizing all assets, especially assets that have multiple levels of intermediaries,” Fink said during Q3 earnings. He called it “the next wave of opportunity for BlackRock over the next tens of years.”
