The headline number doesn't pass the smell test and upon further reading it appears to be utter tosh:
The survey polled a sample of 1,488 senior executives and practitioners in 14 countries (Brazil, Canada, China, Germany, Hong Kong, Ireland, Israel, Mexico, Singapore, South Africa, Switzerland, the United Arab Emirates, the United Kingdom, and the United States). Respondents had at least a broad understanding of blockchain, digital assets, and distributed ledger technology (DLT) and were familiar with and able to comment on their organizations’ blockchain and digital asset investment plans and perceptions, among other metrics.
In order to expand the diversity of our respondent pool in this year’s survey, we identified a group of 100 respondents who are specifically and directly engaged in blockchain technology development projects and also have received a minimum of US$3 million in venture funding in the past year. These 100 respondents took the same survey as the other respondents and are counted among the 1,488 overall respondents in the analysis
So it's not "39% of companies", it's 39% of companies that are involved with blockchain at least to the extent of whatever "broad understanding" means. Not only that, they also diluted the respondent pool ("diversity" LOL) by adding 100 respondents who had $3m in funding, which sounds to me like those are guaranteed to say that they have something in production (about 7% of all respondents).
