BlackRock Piles into Strive's Perpetual Preferred Stock

BlackRock's iShares Preferred and Income Securities ETF (PFF) has significantly increased its stake in Strive Inc.'s Variable Rate Series A Perpetual Preferred Stock (SATA), a move that reflects a growing vote of confidence from the $10 trillion asset management giant.

The ETF, which tracks the ICE Exchange-Listed Preferred & Hybrid Securities Index, more than doubled its position in SATA since June, boosting it by 133% to 236,159 shares. This increase suggests that PFF's rules-based index is recognizing SATA as a legitimate investment opportunity.

Strive Inc., co-founded by Vivek Ramaswamy, has carved out a unique niche by issuing preferred stock that pays investors a variable dividend of around 13% annually. The proceeds from these issuances are then used to buy Bitcoin, with no debt or convertible notes involved. This structure allows Strive to accumulate BTC without incurring significant financing costs.

The SATA instrument has gained traction since its oversubscribed IPO in November 2025, which raised $160 million at $80 per share. With a par value of $100 and a trading range of $99 to $101, SATA is designed to behave like a high-yield bond rather than a volatile growth stock.

Strive's Bitcoin holdings have surpassed 25,000 BTC, with a reported amplification ratio of 53.5%. This metric indicates that the company's Bitcoin per share exceeds what raw equity contributions alone would imply. The presence of both BlackRock and Fidelity as institutional holders suggests that SATA has transitioned from a niche crypto-finance experiment to a more mainstream investment opportunity.

While this move by PFF sends a positive signal, there are also concerns about the potential duration mismatch between SATA's perpetual preferred stock and its Bitcoin holdings. If Bitcoin experiences a prolonged downturn, maintaining the 13% dividend on a shrinking asset base becomes a significant challenge.
