Citadel founder and CEO Ken Griffin has disclosed a significant investment in DeFi Development Corp., acquiring approximately 4.5% of the company’s shares. Citadel Advisors and its affiliated entities hold an additional 2.7%. DFDV, a digital asset fund management firm specializing in Solana (SOL), recently acquired $11.7 billion worth of SOL over eight days, bringing their total holdings to over 21,900 tokens at a cost of approximately $23.6 billion. This positions DFDV as the second-largest SOL holder, trailing only Forward Industries’ 68,200 token holdings. Analysts have cautioned that the Digital Asset Treasury (DAT) model faces challenges with regulation, liquidity concerns, and potential valuation compression.
