Multiple credible sources (The Block, Ainvest, Benzinga) corroborate the statement, specifying that Norway's sovereign wealth fund's indirect bitcoin-equivalent exposure rose from 6,200 BTC to 11,400 BTC in Q2, an 83% increase. The reports consistently attribute this analysis to Standard Chartered. While some sources provide different figures (e.g., 192% or a total holding of 2,446 BTC), the weight of the evidence strongly supports the 83% claim due to its consistency and specific attribution across several reports.
