Not quite 'just like this'. Brunner wasn't talking about prediction markets, but essentially Delphi method panels (https://en.wikipedia.org/wiki/Delphi_method https://en.wikipedia.org/wiki/Delphi_method) which would provide odds for betting (hence the name 'Delphi pool'), but continually rather than merely being convened for a specific issue. Think of it like Las Vegas bookies: there's no 'market', there's a centralized bookie with its own hired guns & expert bettors setting the odds, which may, at its discretion or financial needs, change those odds based on bets its users make.
