Ripple Labs' recent $1 billion share buyback at a $40 billion valuation experienced the lowest participation rate in the company's history. This low turnout suggests strong investor confidence in Ripple's future prospects, especially after its 2023 victory against the SEC and continued growth efforts. The company has steadily increased its buyback valuations, from $11.3 billion in January 2024 to $40 billion, with shareholders seemingly anticipating even higher future valuations.
