I never understood why eBay set things up to enable sniping.
Many years ago, there was an auction site called uBid. They had the sane rule: Bidding is open as long as there have been bids in the past 5 minutes.
So the end date could be January 24th, 3pm, but if someone bids at 2:58pm, the deadline is extended to 3:05pm. And it keeps going.
You know, like how auctions in the real world work.
AFAIK eBay does do this but I’m not sure if it’s only certain categories or it’s configurable by seller. I’ve definitely seen it happen
In my experience, most purely online auctions, other than eBay, do work that way. Numerous auction houses, for example, including essentially all the major ones, have their auctions online now: when they are hybrid, that involves online live bidding where an online bid will cause the auctioneer in the room to keep the lot open for more bids; when they are "timed" or "online only", times are extended in some way on bids near the deadline. It does, in fact, work much better. There is still an advantage to bidding very late: there is no disadvantage, and it lowers bids in cases of irrational or imperfect opposing bidders. But it limits that process to something that can be done by hand.
eBay really seems to be the only auctioneer using the snipable process it uses.
An alternative to ever extending the deadline is a Dutch auction model, where a bid consists of the maximum price you are willing to pay. It's a bit like integrating the snipping bot in eBay and allowing everyone to use it on fair terms.
For example, suppose the current price is $1 and the current winner is someone who bid $2 as their maximum bid ceiling. If I bid a $3 maximum, then I become the winner at a price of $2.
In this model, there is no need for snipping and those who honestly declare their maximum ceiling from the start are in no disadvantage compared to those who frequently update their bid, nor do they overpay.
Unless I’m missing something this is exactly how eBay works. You set a max bid and then it auto bids up to that amount so you can’t get sniped unless they bid higher than your max.
Not that this is perfect either, often it means you can push other people’s bids up to their max even though you have no intention of buying the item. I’ve seen it as a seller and felt bad for the buyers
Completely agree with this. It's very odd that the eBay algorithm has a hard stop, as it directly discourages the price from rising when the bidding is hottest, and is absolutely susceptible to sniping.
This is how the popular car auction site bringatrailer.com bidding process works for cars sold on their site too, a quirk of which is that it makes watching the end of the auctions live online kinda fun, especially given the discussions that break out in comment section on each car up for sale while folks nervously watch the current candidate for the final bid cool down.
Much like your example, in the two minutes before the end of the auction, every new bid placed extends the auction clock by another two minutes, the winner hasn't won the auction until two minutes have passed with no further counter bids.

That's how whatnot does it as well (what eBay badly copied as eBay live)
This how Trade Me (NZ auction site) works: any bid in the last 2 minutes delays the close time to 2 minutes after the bid. That can happen repeatedly, and I've seen it go on for over 20 minutes on highly contended auctions. It works well.
For the auction house that is
For the seller.

There are 9 time zones in the US and depending on what your buying in the eu, jp, etc, I'm not going to be up to deal with the end of an auction, either too early too late or you know I have a real efing job and i'm doing something. Having ends of auction require you to be around means you lock out large parts of the market.
It doesn't need to!
If the winner, instead of paying what they bid, pays what the second-highest bidder bid (and bids are secret until someone exceeds them) then the incentives change. Everyone is incented to bid what it is worth to them, safely knowing (1) they won't pay more than that, (2) they will win the auction if no one outbids them, and (3) they won't pay more than necessary to win the auction.
eBay works this way (more-or-less), so you CAN (if you choose to) simply place your bid any time that is convenient and then ignore the timing of the end of the auction and all the sniping bots.
...that's what auctions are...being around to bid...

This is how Yahoo! Japan Auctions works. If an auction receives a bid in the last few minutes, it is automatically extended.
It works quite well!
Guessing here - but they are probably relying on game theory / auction theory. They have a built in "sniping bot" - by allowing you to type your highest price, and it will auto-bid for you until that price.
The fear of being sniped encourages you to bid your maximum value, and not just wait and see if you can sneak in a lower bid. This is what all auction sites want.
> They have a built in "sniping bot" - by allowing you to type your highest price, and it will auto-bid for you until that price.
With ubid, you also had the feature of letting it bid to your highest price. Yet they still extended the auction if someone outbid your highest price.
Except nobody uses it that way. Auctions are rare themselves. Sellers dont like it, buyers dont like it yet ebay won't change it.
People will pay a premium to win, not everyone but enough to make it worth it.
Another eBay precursor auction side, onsale.com, had the same setup. The auction ended at X date/time or five or ten minutes (I forget which) after the last bid was made.
There is no need for that. They only need to implement a closing auction like stock markets. But eBay hasn't done anything since the 1990's except raise fees.
Nothing? Don't forget when their security team sent pigs heads to people and terrorized them:)
I think I missed this…

Meanwhile it's now 100% free to sell on eBay for non-professional sellers.

They're playing stupid semantic games in order to claim there's no selling fees while still having selling fees. The fees were ostensibly shifted onto the buyer, except they're bundled into the sale price and cut from what the seller receives, so in effect nothing actually changed.
Before: Buyer pays £100, seller receives £100, seller later charged £5 fee, ends up with £95.
After: Buyer pays £100, eBay pockets £5 "buyer protection fee", seller receives £95 with "no fees".

Nice:
> You won't pay final value fees or regulatory operating fees
Of course, they will likely find some other way to extract their fees.
It would be nice, however, if the final value fee went away for US non-professional sellers.
There does seem to be no indication (at least on the page you linked) of how they define "private seller", which also opens up the possibility of them defining it so narrowly that, say, only five UK residents ever qualify.
Only in the UK, and only on "private sellers". eBay is losing a lot of marketshare in the UK so they've taken drastic measures to try to get people listing again.
