Attention Markets

Attention Markets

An attention market is a prediction market where the underlying asset is narrative attention rather than a price or an event outcome.

Why attention?

In crypto, narrative is primary. The price of a token is often downstream of the story around it. Attention markets let you express a view on the story directly — without needing to pick the right token or time a volatile entry.

How SentiDex measures attention

SentiDex aggregates signals across multiple dimensions:

  • On-chain activity — transaction volume, new addresses, protocol usage
  • Market positioning — open interest, funding rates, relative performance
  • Social momentum — discussion volume, sentiment velocity, narrative spread
  • Developer activity — commits, releases, ecosystem growth

These signals are normalised, weighted, and combined into a single attention score per category, updated continuously.

Categories

Each SentiDex market represents a distinct crypto narrative:

The reserve bucket

Each market maintains a reserve position — a pool of attention not yet allocated to any specific category. As attention concentrates, the reserve drains. As it fragments or disperses, the reserve refills.

The reserve acts as a market-wide uncertainty measure. A high reserve means attention is diffuse; a low reserve means the market has strong conviction about where attention is flowing.

Expanding markets

SentiDex markets are expanding — new positions (new categories) can be added as new narratives emerge. This reflects the reality that attention markets are open-ended: new stories appear, old ones fade.

When a new category is added to an existing market, the LMSR re-prices all positions to reflect the new distribution. Existing holders are not diluted in expected-value terms.
