peakmonsters has a "richlist", which you can configure for vouchers. i couldnt properly link it. (https://peakmonsters.com/richlist)

Here is a screenshot. You can see, that #2 - #7 are people with >1mil sps that receive(d) the daily max of vouchers, and have not sold a single one of them. The follow ups are similarly big fish with lots of sps staked. The big question will be, if those vouchers will enter the market or will be used privately. Then there is also the @sl-hive, but i guess that is liquidity pools?
