About Retro Trader

“Here’s an API. Bernard and 88 other people can market-make all these request-for-quotes (RFQs),” Marantelli says. “Some people might come in and just do esports because they’re esports experts. Others do everything. Some focus on same-game parlays. But it’s a sportsbook.”

The institutional layer is largely invisible to customers presented with a P2P proposition. Retail users may technically trade against one another, but the depth required by a mass-market product cannot be supplied by occasional customers alone. Professional firms must be prepared to quote continuously and commit substantial capital.

Marantelli says the London-based White Swan is a significant market maker on several secondary exchanges, accounting for as much as 40% of activity on some platforms. Its particular focus is the RFQ, parlay market.

What is Retro Trader?

However, LSR noted that traditional game outcomes are no longer reliable indicators of bookmaker profitability, largely due to the rapid growth of same-game parlays and player props.

In the Las Vegas-based Circa Survivor contest, which drew over 25,000 entries entering Week 1, more than 8,000 entries were eliminated in the opening slate—most knocked out when the 8.5-point favorite Chargers fell to the Cardinals. That upset served as a proxy for the wider market, ruining countess parlay tickets across major sportsbooks.

Looking ahead to Week 2, bettors continue to chase high-scoring games. At BetMGM, Overs represent three of the five most-bet game totals by ticket count: Vikings-Bears (Over 48), Saints-Ravens (Over 46), and Panthers-Falcons (Over 44).
