According to @StockMKTNewz, multiple marquee investors including Warren Buffett and Bill Ackman updated their portfolios this week, with a thread outlining their largest holdings as of the end of Q3 2025 (source: @StockMKTNewz, Nov 16, 2025). According to @StockMKTNewz, the thread begins with Berkshire Hathaway’s positions, providing a snapshot of where major institutional capital was concentrated at Q3-end for trading reference (source: @StockMKTNewz). According to the U.S. SEC, quarterly equity holdings by qualifying managers are disclosed on Form 13F up to 45 days after quarter-end, offering traders a standardized view into institutional long positions for the prior quarter (source: U.S. SEC, Form 13F).

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).

According to @burrytracker, Michael Burry has disbanded Scion Capital; the post provides no supporting details or documents (source: @burrytracker on X). Traders seeking verification should monitor SEC EDGAR for a Form ADV-W adviser withdrawal and any changes in 13F reporting that would confirm structural wind-downs (source: SEC.gov). Equity–crypto correlations have risen since 2020, so risk sentiment headlines around prominent hedge fund managers can spill over to BTC and ETH (source: IMF Global Financial Stability analysis, 2022).
