Block trades and request for quote on event venues

Most readers see prediction market prices as a public order book with bids and offers. But some venues also offer ways to trade larger or more complex positions through requests for quotes or negotiated block-style trades. These mechanisms affect what trade history shows and how prices move. This SoftCta guide explains the concepts without endorsing any trading activity.

Why the visible book is not enough

Event contract order books are often thin, especially away from the most popular markets. Our depth guide and slippage guide show how a large order can walk through several price levels. Displayed size may also not reflect true available liquidity, as covered in our displayed size guide.

How RFQ works

In a request-for-quote flow, the requester specifies a contract or combination and size. Liquidity providers respond with prices for a short time. If the requester accepts, the trade executes at that price. Venues offering RFQ for combination or parlay-style contracts use it because custom combinations have no standing order book. Features and availability vary by venue and change over time; verify live on the operator.

Who quotes

Quotes usually come from professional market makers who manage inventory across many markets. They price in the risk of trading against better-informed participants and the cost of hedging, so quotes on large sizes are often wider than the top of the book.

Reading prints from negotiated trades

When large negotiated trades appear in public history, they can look like sudden jumps or unusual volume. They do not necessarily mean the market consensus changed; a single participant's need to trade size can drive the print. Our trade history guide explains how to separate fill quality from information.

Fees and rules

RFQ trades may carry different fees or minimum sizes. The fee drag tool can help illustrate how fees affect effective price with your own assumptions. Venue rulebooks set reporting, cancellation and error-trade policies that apply to negotiated trades too.

Common pitfalls

  • Assuming an RFQ quote beats the book without comparing.
  • Reading a large print as new information.
  • Ignoring different fee schedules or minimums.
  • Assuming every venue offers RFQ or reports it the same way.
  • Treating quoted prices as standing liquidity.

Primary sources SoftCta readers open

  • Venue rulebooks and help pages on RFQ and combination trading.
  • Public trade history and API documentation describing trade flags.
  • Fee schedules published by each venue.
  • Regulatory filings describing execution methods for regulated exchanges.

Reading the quote step by step

  • Read the full title and rules, including the named settlement source and the time zone.
  • Convert the Yes and No prices to implied probabilities and note the gap between them.
  • Subtract fees and spread to see the effective price you would actually face.
  • Write your own probability range and the evidence behind it, then compare.
  • Check related and near-duplicate markets on other venues for consistency.

Closing SoftCta checklist

  • Re-read the venue definition in your own words before reacting to a price.
  • Convert prices with fee and spread awareness; verify live cents on the operator.
  • Prefer primary settlement sources over secondary headlines and social summaries.
  • Treat ChanceWire hubs, movers, and tools as orientation — not order entry.
  • Confirm age, location, and product eligibility; SoftCta pages will not suggest location spoofing.
  • If clarity is incomplete, watching is a complete SoftCta outcome — no pick-selling urgency required.

SoftCta habits

  • Write your own probability range before checking the crowd price.
  • Prefer dated primary sources over social summaries.
  • Compare related markets when a single book looks extreme.
  • Size curiosity with fees and depth in mind; substantial risk of loss.

FAQ

What is a request for quote?
It is a workflow where a participant asks liquidity providers for a price on a specific size or combination of contracts, then chooses whether to accept a returned quote instead of trading against the visible order book.
Why would someone use RFQ?
Large or complex orders can move thin order books significantly. Requesting quotes can reduce visible price impact and may be the only practical way to price custom combinations.
Do RFQ trades show in trade history?
It depends on the venue. Some report executed trades publicly with a flag or after a delay; others only show them in aggregated volume. Check the venue's documentation.
Is an RFQ price better than the book?
Not necessarily. Quote providers price in risk and may quote wider for large or unusual requests. Comparing with visible depth and fees is necessary.
