According to the source, Harvard Management Company tripled its Bitcoin exposure via U.S. spot BTC ETFs while Emory University increased its BTC ETF positions, with the report based on recent institutional Form 13F disclosures (source: U.S. SEC EDGAR Form 13F). In U.S. spot Bitcoin ETFs, net inflows trigger primary creations that require custodial BTC purchases by issuers such as BlackRock iShares and Fidelity, linking 13F-reported positions to spot-demand metrics traders can track (source: iShares Bitcoin Trust and Fidelity Wise Origin Bitcoin Fund prospectuses). Traders should verify share counts and specific tickers held by Harvard and Emory on SEC EDGAR and monitor daily net creations for IBIT, FBTC, ARKB, BITB, HODL, BTCO, and BRRR on issuer sites to gauge incremental BTC demand (source: U.S. SEC EDGAR; issuer daily flow pages).
