They re-added it again as the poster above has mentioned but if you dig further you will realise that it was actually listed on DTCC back in August. They made a post about and they also said its not a full gaurantee that it will get listed.
I'm glad someone is paying attention here. I also read that it was initially listed in August, although I couldn't find a reliable source to prove it. No archive or anything.
So I don't think yesterdays rally had anything to do with DTCC since it rallied hours AFTER someone posted that on twitter AND the DTCC had it listed since August and anyone could of checked before hand.
Personally I think it 99% was this. You're right that anyone could have checked since August, but the reality is it seemed no-one did, hence the news only breaking this month. That is of course if the rumours were true that it first appeared in August, given I haven't seen any proof of that yet, it could just be a rumour attempting to temper expectations / manipulate price back to the downside.
The fact that it took a few hours for price to rally makes sense, that's how long it takes for news to spread on twitter/elsewhere and for people to take it seriously, and for the price to break through resistance.
I think this rally is due to some insider knowing 100% its approved or will be approved sometime within the next few weeks. Don't think its retail buyers which are causing this.
I think many people took the ticker listing not as a sign of approval, but a sign that Blackrock (and now Ark) believe it will be listed. As far as I understand in order to make this listing you need to have the available starting liquidity for such an ETF. In Blackrock's case, this potentially means they bought Bitcoin as far back as August to cover this, so people got bullish with the idea that Blackrock bought Bitcoin, which they would have only done so if they believed an approval would be coming soon - or at least that's the theory. It could also simply mean they believe the BTC they buy will be worth more at time of listing, even if that's months/years away.
The other reason for people to be bullish would be that other ETF applicants may also now be creating their tickers and needing to acquire the necessary liquidity for launching, at current prices. Sure this is all 100% speculation regardless, but often enough that can be what initially moves the market, prior to genuine demand over an asset that is having a strong recovery from a bear market.
