Arena Live

Arena Live is by application, for up to 10 design partners.

Live is not available today. Arena is a sandbox: orders fill against live public prices with a virtual balance, a position held to the end settles against the real outcome, and no order leaves Arena. Arena Live is a planned way for a business to send orders through Arena to its own account at a venue. We are looking for up to 10 design partners to help shape it.

Access
Live is by application, for design partners only.

How live would work

Planned, subject to legal and regulatory review, and may change.
  • You link your own API key from the venue, for an account in your entity's name.
  • Arena sends an order only on your instruction, with your credentials.
  • Fills, fees, funds and settlement stay at the venue.
  • You can turn live off with one switch, and so can Arena.

Venues in scope

  • Kalshi first, starting with Kalshi's demo environment.
  • Other venues only once Arena has a written relationship with them.
  • No live orders to Polymarket's international exchange for US persons.

Who can apply

  • A registered business entity.
  • An existing account at the venue, in the entity's name.
  • A named person responsible for that account.

What Arena will not do

In the live design, Arena will not:
  • Hold customer money or positions. Arena takes no custody.
  • Pool customers' money into a shared bankroll.
  • Match or cross one customer's orders against another's.
  • Trade against customers.
  • Send a live order without the customer's own venue credentials and the customer turning live on.

Applying does not open an account, and no order is sent.

Disclosure
