The claim is sourced to @DeItaone (Walter Bloomberg), a well-established and widely-cited financial news relay account on X, whose May 8, 2026 post matches the claim precisely including the specific figure of 837 investors, the 43% normalization-after-July finding, and the $80-$90/bbl Brent cluster. The post was rapidly and widely retweeted, and the details are internally consistent. The broader context is strongly corroborated: WSJ reported Goldman Sachs raising its Brent forecast due to prolonged Hormuz disruption in March 2026, and BlackRock's May 2026 dashboard confirms ongoing Hormuz shipping disruptions. However, no primary Goldman Sachs document, research note, or official GS press release was located to independently verify the survey's existence and specific figures, which limits confidence. The claim is assessed as likely true given the credibility of the relay source and strong contextual corroboration, but cannot be rated as confirmed without a primary GS source.
