First, the rebate comes entirely from the registrar margin. It’s not funded by other bidders and it doesn’t increase the price anyone else pays. If the Stage 1 bidder wins, we simply give up part of our margin. In other words, it’s a commitment incentive funded by us a risk-sharing mechanism, not a cost imposed on other bidders.
Well stated, and if there was no "commitment incentive" present in your "market design" then absolutely no one would have a reason to bid.
Every auction system is inherently weighted against the bidders and by a domain being listed, it automatically increases the price for anyone taking part. That's the punishing "whip", so therefore every auction system also need a "carrot" to draw customers in.
At Grape it's a preorder discount, while at WHC it's the (increasingly unlikely) chance that you just might win a mid-range or lower-end domain for $20, assuming no one else bids. But without this carrot, no one would bid.
But if I may, I find these TBR "carrots" to be rapidly losing their value, and in some cases, disappearing entirely.
For example, if every major bidder preorders every single premium at Grape, then there is no discount. Then everyone is on a level playing field with no pricing/discount advantage for anyone.
And with WHC experiencing a spike in demand from new bidders, not to mention their 'everything but the kitchen sink" Hot List, it's almost impossible to outright win a domain, as even the junk goes to auction. Previously at WHC, you would win some mid-range/lower-end domains outright, while the top stuff went to auction (fair trade), but not anymore, as auctions are what makes WHC the real money. So their "carrot" being shunted to the back of the TBR bus, and is quickly turning into a fairy tale I'll tell my grandkids.
The current TBR auction levels are unsustainable, so I'm sure we'll see a corresponding implosion a bit later as the newbs figure out that .CA isn't a Get Rich Quick scheme, but for now, it's a rough game and one slanted directly towards the TBR registrars and their withering carrots.
