What else matches news to Polymarket markets.
Matching news to prediction markets is not a new idea and we are not first. At least half a dozen products do a version of it today, the largest of them built by Polymarket itself and free since April 2026. If one of them already solves your problem, use it — this page exists so you can work that out without emailing us.
Checked 3 November 2026. Prices and capabilities below come from each vendor's own public material on that date and change without notice. Verify before you commit to anything.

Where we are actually different
Not in finding relevance. Vera does that, Polymarket's own Draft Analyzer does that free, and a free MCP server does it well enough to drop into an agent in one line. Anyone claiming relevance matching as a moat in late 2026 is not looking at the field.
The difference is that a Throughline match is designed to be checkable, and the four things that make it checkable are the things nobody else publishes:
- evidence tier
- Whether the judgement came from the full article, a summary, or a headline alone. A confident reason drawn from a headline is the most common way these systems mislead, and it is invisible unless the tier is published.
- readable withdrawals
- A retracted match stays in your copy at its final revision with the reason it failed, rather than vanishing. A match that silently disappears is indistinguishable from one that never existed.
- screening state
- A separate endpoint distinguishes "we checked and nothing matched" from "processing is behind or broken". Everywhere else both return an empty list.
- disclosed boundary
- We trade these markets. The relevance judgement is not given the price, nothing price-dependent is published, and no trading predicate narrows what gets published. A competitor cannot copy this claim without acquiring the conflict it answers.
That is an auditability argument, not a quality argument. We are not claiming better relevance than Vera. We are claiming you can tell when ours is weak.
When one of the others is the better answer
- You need something todayThroughline is not serving yet. Every product above is. This is the decisive point for most people and it will stay true for a while.
- You want raw market data, not relevancePolymarket's own Gamma and CLOB APIs are the source of record, and Adjacent News is the better multi-venue wrapper. We are a layer on top of markets, not a replacement for market data.
- You trade more than PolymarketWe start with Polymarket geopolitical markets only. Adjacent News covers Kalshi, Manifold and Metaculus as well.
- You want a dashboard, not an APIVera Trader is a no-code product. Throughline will be an API first; the reading interface is a maybe, not a plan.
- You want an agent tool in one lineThe open-source MCP server installs with a single command and needs no key from anyone.
The honest risk to us, stated plainly
Polymarket's Draft Analyzer already does the free version of the core matching. If Polymarket exposes it as a public API, most of the reason to use a third party for basic relevance goes away in a week. We think the verifiability layer survives that and the plain matching does not, which is why the work is pointed at the former. You should know that is a bet and not a finding.
