Bloomberg reports Goldman Sachs disbanded its quantum computing team while JPMorgan continues investing — Wall Street strategy diverges
Bloomberg published a 2026-04-26 feature reporting that Goldman Sachs has dismantled its internal quantum computing team after, per the article's account of internal Goldman findings, the bank concluded that solving a representative portfolio-optimization problem would require on the order of 8 million logical qubits — far beyond the under-100 logical qubits available on current systems — alongside broader cost-cutting. JPMorgan Chase is reported to maintain a team of roughly 50 specialists working on optimization, machine-learning, and cryptography applications. Multiple secondary outlets (TheStreet, Yahoo Finance, Communications Today, Seeking Alpha) carried the divergence framing within 24 hours.
A major Wall Street enterprise customer publicly stepping back from quantum computing R&D investment is a meaningful but non-decisive sentiment signal for the public-quantum equity universe — particularly while Quantinuum's IPO and IonQ's catalyst chain are open threads. The Bloomberg framing ties Goldman's decision to a specific resource-estimate gap (millions of logical qubits versus the current sub-100-logical-qubit installed base), which is consistent in spirit with the Caltech/Oratomic 10,000-qubit Shor estimate (2026-03-31, score 7) at the lower bound and with operational-research literature on portfolio-optimization quantum advantage at the upper bound. The lack of a primary statement from either Goldman or JPMorgan caps source confidence at medium; the lack of an event-typed corporate disclosure keeps the score below the §8.2 score-6 anchor band.
If JPMorgan files a quantum-related research output (peer-reviewed or arXiv) within the next quarter that explicitly cites a near-term application target, the divergence narrative gains a primary-source counterweight. Conversely, additional bank-side pullbacks (named teams at Citi, Wells Fargo, Morgan Stanley, BNP, Barclays) would aggregate into a stronger enterprise-demand signal worth a higher-score follow-up. The story is also consequential for Quantinuum's IPO narrative — the IPO targets Q2 2026 deconsolidation per Honeywell (2026-04-23) and depends on a public-equity market that prices quantum as a multi-decade thesis rather than a five-year one.
