Overview

  • The Schedule 13G lists 1,315,654 DeFi Development shares under Griffin’s beneficial ownership, equal to 4.5% of the company.
  • Coverage of related filings indicates Citadel-linked entities hold roughly 800,000 more shares, bringing broader Citadel exposure to about 2.1 million shares.
  • DeFi Development reports about 2.19–2.20 million SOL staked via validators, accounting for roughly 0.40% of Solana’s circulating supply.
  • In August, the company completed a roughly $124 million PIPE that took cash and locked SOL or interests in SOL-holding entities, with Citadel participation noted.
