Sources: Yahoo/Reuters — Citadel buys most of Situational's stock holdings; The Information briefing on the WSJ report; TechCrunch — sold the public book, kept Anthropic. Surfaced by the desk's own news lane 12-source convergence (Bloomberg Markets, CNBC Top News, Semafor, r/investing, r/stocks, r/wallstreetbets, multiple X accounts).

Verification (2026-07-30 EOD)

• Citadel bought the bulk of the public book: VERIFIED — WSJ original, Reuters ("sources say"), The Information, TechCrunch all carry it independently of each other's paraphrase. Purchase price NOT disclosed; securities NOT itemized by the Journal.
• "Bulk/most", not "entire": the stronger record softens CNBC's morning claim. Reuters: the fund retains ~$10 billion post-transaction, "comprised of stocks as well as private investments in companies like Anthropic." The morning's "entire public equities portfolio" (CNBC) is now the weaker sourcing — treat the sold portion as "the bulk of the public book."
• Anthropic stake RETAINED: VERIFIED (Reuters/TechCrunch) — resolves the article's open question about whether the private book comes to market next. It did not, so far.
• Millennium submitted a competing bid: WSJ-attributed via secondary recaps — single reporting family, PLAUSIBLE; attribute if used.
• Down ~67%
