Harvard Cuts Bitcoin ETF Holding 43%; Exits Ethereum Fund

Posted: 17 May 2026, 11:16 CET 2 min read

Harvard trimmed its iShares Bitcoin Trust holding 43% to about 3.04 million shares (~$117M) and fully sold its spot Ethereum ETF in Q1 2026; Mubadala raised IBIT to ~14.72M shares (~$566M).

Harvard Management Company reduced its holding in BlackRock’s iShares Bitcoin Trust (IBIT) by about 43% to 3,044,612 shares, worth roughly $117 million, and fully sold its position in BlackRock’s spot Ethereum ETF during the first quarter of 2026, filings with the U.S. Securities and Exchange Commission show. The disclosures appear in Q1 2026 13F filings reporting holdings as of March 31.

The filings show Harvard first disclosed an IBIT position in mid‑2025 after buying roughly 1.9 million shares for about $117 million. The endowment expanded that stake to a reported value near $443 million by the third quarter of 2025, trimmed it by 21% in Q4 2025, and reduced it by a further 43% in Q1 2026. Harvard had established an $86.8 million position in BlackRock’s spot Ethereum ETF one quarter earlier and has since exited that holding entirely.

The Q1 filings indicate IBIT is no longer Harvard’s largest disclosed public‑equity holding; Taiwan Semiconductor Manufacturing Co., Alphabet, Microsoft and the SPDR Gold Trust are listed ahead of the Bitcoin ETF in size. The 13F reports do not include commentary from Harvard Management Company explaining the trades.

Abu Dhabi’s Mubadala increased its IBIT position to 14,721,917 shares, valued at about $566 million, up from 12,702,323 shares at the end of 2025. Mubadala’s filings show additions to the Bitcoin ETF position each quarter since Q4 2024.

Other institutional moves in the Q1 2026 13Fs include a roughly 71% reduction in IBIT by trading firm Jane Street and a near 60% cut in Fidelity’s FBTC by the same firm while it added to BlackRock’s ETHA and Fidelity’s FETH. Emory University fully exited a small IBIT position and moved Bitcoin exposure into the Grayscale Bitcoin Mini Trust. JPMorgan increased its IBIT stake by about 174%, and Wells Fargo expanded its Ethereum ETF holdings.

The next quarterly 13F disclosures, due in August for Q2 2026, will show whether Harvard continues to change its Bitcoin ETF exposure and whether Mubadala’s accumulation continues.
