Antalpha AI / Nina predictions

Quick answers

What does it cost?

Current features need no subscription; the provider describes a routing fee without a numeric prediction rate.[1][2][3]

Does it trade for me?

The docs say each order is signed by you; monitoring and analysis do not themselves authorize automatic trading.[1][2][3]

Where do my funds sit?

The provider says funds and keys remain in your wallet, with unsigned drafts prepared by its cloud service.[1][2][3]

What do I need to start?

An account, eligible wallet, funding and a reviewed prediction-account authorization for trading.[1][2][3]

Where is it available?

Web and native mobile apps are described; order eligibility can differ from analysis availability by region.[1][2][3]

Overview

Trading mode

The provider says every in-product order is signed by the user and that monitoring does not trade automatically. Connected external tools have their own authorization requirements.[1][2][3]

Funding and prerequisites

An eligible account and wallet for live trading, with funds for prediction settlement on Polygon. Analysis access and permission to place orders can differ by region.[1][2][3]

What it offers

• Event search and analysis

  Find venue events by a natural-language query and inspect the provider’s stated evidence and source labels.[1][2][3]

• User-signed orders

  Activate a prediction account with an authorization, then buy, sell or redeem through the product’s prediction interface.[1][2][3]

• Sentinel monitoring

  The mobile documentation describes ongoing event monitoring with push notifications and an explanation of the reported change.[1][2][3]

• Recurring reports

  Configure scheduled analysis and price alerts separately from a trading authorization.[1][2][3]

• External integrations

  Official docs and a public setup repository describe connecting analysis tools through the provider’s MCP endpoint; no client or endpoint was installed or called.[1][2][3]
