Confidence: Directional-Speculative.

Caveat: All are report-sellers. The ~7× spread between estimates for the same period is itself the finding — these figures are unreliable.

Why this matters for Candid: When a client cites a market-size projection to justify "everyone is doing portals," show them the spread. Same pattern as the calculator brief's The "2× engagement / conversion" interactive-content stat is widely (mis)attributed to "Content Marketing Institute" — no original CMI dataset producing it exists and the data brief's The "McKinsey: 83% of B2B customers value transparency over brand reputation" stat is not verifiable to any primary McKinsey publication — vendor-laundered stats are the rule, not the exception.
