Bid
Demand enters
Advertisers and demand-side platforms return a price against an impression-level request, inside the stated window.
Sivora Exchange Marketplace International scale
Exchange / Marketplace
The exchange that clears demand against supply.
Sivora Exchange is a matching venue, not a media agency. It accepts publisher inventory, solicits eligible advertising demand, runs a real-time auction, and returns a result under published rules.
The meeting
Demand, the exchange, and publisher supply.
Sequence
How a trade is taken to clear
01
Intake
Supply presents an available impression with the objects required by the protocol.
02
Construct
The exchange builds a bid request for demand seats that are eligible for that inventory.
03
Bid
Demand returns bids within the stated response window. Late or malformed responses are
not considered.
04
Match
The auction method in force selects a winner among eligible bids. Method details are
shared with accepted participants.
05
Clear
Win or loss is returned. When a bid wins, the creative path proceeds toward the
audience on the offered inventory.
Ticket
Bid, seat, and clear
The marketplace treats each impression as a paper ticket would: a bid is stated, a seat is eligible or it is not, and the exchange records the clear.
Seat
Who may trade
A demand seat or a supply seat is reviewed onto the exchange. Eligibility is applied before the auction compares bids.
Clear
The auction settles
Eligible bids are compared. A result returns to both sides. The impression path continues toward the publisher’s audience.
Control
What each desk still owns
Demand controls
Buying side
Demand sets bid price, buying eligibility, and the constraints attached to each bid. The desk does not rewrite supply floors or seller blocks.
Bid, brand constraints, and the inventory the desk is willing to buy.
Supply controls
Selling side
Supply sets floors, blocked buyers or categories, and the inventory object it discloses. The desk does not set demand bid strategy.
Floors, buyer eligibility, and quality expectations for offered inventory.
Neither side sets the other’s controls. The exchange applies the published method to the objects it receives.
