QBTS in this quarter's filings
Concentration check: the largest reported position, BlackRock, Inc. with 33,147,399 shares, is 16.8% of all shares reported for QBTS this quarter. The five largest reporting managers together account for 46.6% of the reported total, so the headline total is spread across a broad manager base rather than a few holders.
Reported quarter-over-quarter change: the reporting-manager count rose by 62 versus the quarter ended 2026-03-31, and reported shares moved +12.71% (+22,298,040 shares). That is a comparison of two filing snapshots, not a record of trades on any single day.
Shares-outstanding cross-check: reported 13F shares equal 53.3% of the issuer share count used at the publication gate (370,840,115 shares, issuer period ended 2026-06-30). The gate publishes a ticker only when that relationship is plausible; lending chains can push reported totals above a simple ownership share, which is why the figure is a sanity check and not an ownership percentage.
