Wisconsin Pension Fund Discloses Its Exit From BlackRock’s Bitcoin ETF
The State of Wisconsin Investment Board’s May filing showed that it had fully exited its previously disclosed IBIT position during the first quarter, reversing a closely watched public-pension Bitcoin investment.
On May 15, 2025, institutional filings revealed that the State of Wisconsin Investment Board no longer held the position in BlackRock’s iShares Bitcoin Trust that it had disclosed in earlier reporting periods. The underlying sales occurred during the first quarter of 2025; May 15 is the date the exit became public, not the date of the trade itself.
Wisconsin’s original Bitcoin ETF investment had attracted unusual attention because it represented a state public-pension institution taking regulated Bitcoin exposure. That disclosure helped legitimize Bitcoin as an investable asset for government-linked institutional portfolios. The subsequent exit therefore mattered for the same reason: it demonstrated that institutional adoption was not necessarily permanent or one-directional.
Rather than treating the divestment as evidence for or against Bitcoin itself, the historical significance lies in the maturation of institutional behavior. A pioneering public investor could enter, resize, or exit Bitcoin exposure within conventional portfolio-management processes. The May disclosure captured an early example of Bitcoin becoming an asset subject to the same allocation reversals and reporting scrutiny as other institutional holdings.
