Fact Check

The core claims are directly verified by the primary authoritative source: Harvard Management Co Inc's Q1 2026 SEC 13F filing (period 2026-03-31, filed 2026-05-15), retrieved directly from SEC EDGAR. That filing confirms Harvard held 3,044,612 IBIT shares (~$117M) with no Ethereum ETF position present. Multiple credible news sources (Cryptopolitan, Yahoo Finance) citing the same SEC EDGAR filings confirm the ~43% IBIT reduction from Q4 2025 and the full exit from the ~$86.8M Ether ETF position. Bitcoin Magazine independently confirms Mubadala raised its IBIT stake 16% to ~$566M in Q1 2026 per its own 13F filing. All key facts in the claim - Harvard exiting Ethereum ETF, cutting IBIT by 43%, and Mubadala increasing IBIT holdings - are corroborated by the primary SEC filing and multiple independent secondary sources. The minor residual uncertainty (0.03) reflects that the exact 43% figure and prior Ethereum ETF value were not independently re-verified from the Q4 2025 13F document itself in this run, though all secondary sources are consistent.

Summary

First-quarter 2026 13F filings with the U.S. Securities and Exchange Commission show Harvard’s endowment cut its stake in BlackRock’s iShares Bitcoin Trust by about 43%, leaving 3,044,612 shares valued at roughly $117 million, after already trimming the position by 21% in the fourth quarter of 2025. Harvard also fully exited its BlackRock Ether ETF position, eliminating exposure described in the source as about $86.8 million. The filing reflects a broader reduction in the endowment’s reported exposure to spot crypto exchange-traded funds. The source also notes that Abu Dhabi sovereign wealth fund Mubadala Investment Company moved in the opposite direction, increasing its IBIT holdings to 14,721,917 shares worth about $566 million, up from roughly 12.7 million shares at the end of 2025.
