The Black Hole Index™ measures the cost of leaving.
A standardised, peer-reviewable instrument that scores how structurally locked-in a platform is — independent of price, market cap, or sentiment.
: no platform score changed.
- —All 184 scores are identical to the previous release; no platform changed zone.
- —The quarter's work went into the evidence behind the scores and into the release machinery, not into the scores themselves.
- —What the index measures, and what it does not, is set out in the methodology; corrections are appended to the public record.
BHI is a standardised score measuring how costly it is for a user, organisation, or counterparty to depart a platform — capturing the structural friction of leaving rather than the value of staying.
It is computed as the ratio of capture pressure over escape capacity, evaluated across eleven measurable parameters and re-released every quarter under a transparent rubric.
The CMA published all 37 non-confidential responses to that consultation, Apple’s and Epic’s among them. Publication means a response was received and published — it is not endorsement. No regulator has adopted, evaluated or expressed a view on this instrument.
A 4-minute read on platform lock-in, every quarter.
