The behavior already exists
People already publish market calls on X. They post screenshots, argue in replies, cite sources, and explain why they think a price is wrong.
That activity has value, but the record is fragile. The post is hard to find later. The evidence is scattered. The outcome often does not attach back to the person who made the call.
The Eva wedge
Eva starts by giving those calls a durable structure. A market thesis has a market, an outcome, an odds snapshot, a rationale, source links, and a page that can be shared or challenged.
That is enough to make a prediction more useful before any native settlement layer exists. A reader can inspect the reasoning. Another predictor can counter it. A curator can improve the evidence trail.
Why reputation matters
The valuable question is not only whether one call was right. The valuable question is who keeps making useful calls and who keeps improving the evidence record around them.
That is where EvaTrustGraph matters. The trust graph gives Eva a durable place to remember identity and reputation as the product moves from offchain thesis records toward stronger graph-backed feedback.
The honest boundary
Eva does not need to execute trades to make prediction markets more legible. In v1, copy actions are previews and external links only.
The product should prove that people want public reputation for their reasoning before Eva takes on deeper settlement, payment, or market infrastructure.
