Proof of Usefulness Score
Category Standard

StockX is a verified market unicorn ($3.8B valuation) with immense real-world utility, effectively creating the 'stock market of things' and solving the authenticity crisis in resale. While the project itself is a category leader with global reach, this specific submission was low-quality (vague claims like 'everyone' and 'most people'), resulting in significant penalties to the Audience Reach and Response Quality metrics. However, the verifiability of the brand and the specific market cap data provided sustained a high overall score.
