The KOSPI is already down 38% from its peak
If AI actually turns out to be a bubble and it pops, does Korea get wiped off the face of the Earth?
Does Citadel own the entire country at that point or what?
We went from:
> Anthropic could wipe out humanity
> Astra is AGI
> Software is worthless
To:
> AI isn’t even that useful
> Anthropic’s growth is disappointing
> OpenAI has zero moat
In like a month.
Crazy how the human mind works, huh?
I think the groundwork is sort of laid here for a long $ARM / short $AMD pair:
- Arm should start to show progress in server CPU at some core AMD customers next year at significantly lower ASPs than Venice
- Arm ASIC + in-house CPU are not in numbers yet whereas AMD contends high
I’m starting to think memory might be the next huge bottleneck, and it’s dominated by 3 unknown companies: $MU $SKHY and Samsung. Why is nobody talking about this???
The neocloud takes I’m seeing are so funny
Where were these people a month ago?
Exaggerating every little fact for cheap clicks by clueless trend followers
Oil is above $100. The main reason it's not closer to $150 is all the oil being released from the Strategic Petroleum Reserve. That will stop after the midterms. When it becomes obvious that inflation will outpace Fed rate hikes, the dollar will fall, sending oil prices soaring.
$IREN bought $AMD chips, and they’re a sponsor at GTC Berlin
Same with DigitalOcean
Same with Crusoe
Same with Vultr, which is more of an AMD cloud than an NVIDIA one
Yeah, this is BS
SHOCKING: We have confirmed that multiple Neoclouds have been refused access to GTC Berlin due to them adding AMD GPUs, TPUs, and other chips to their cloud offerings
Note that this doesn't apply to hyperscalers, as they have more buying power. But for neoclouds, executives feel
I’m a bit amazed sometimes
I thought the whole thing was obviously just a spectacle
Do people actually believe they’ll be able to buy and use this?
The whole thing is so absurd

I have a Russian guru and his two Indian partners sitting across from me, talking to some poor woman about the soul and the afterlife
Now they've switched to blockchain and tokenization stuff
Oh man, someone is getting cult-scammed so bad
“Either our estimates are way off, which means the sell-side estimates are also way off.”
Oh man, he’s already covering his ass
So he has zero edge? He’s just basing his buys on sell-side consensus?
Why would anyone pay for that? If it’s consensus, it’s literally priced in

Samsung, SK Hynix Aim to Ease AI Memory Bottlenecks with zHBM, HBF
At SEDEX 2026, both companies showcased next-generation memory technologies targeting AI performance and efficiency
SK Hynix highlighted High-Bandwidth Flash (HBF), targeting 10× HBM's capacity at 50% of its bandwidth, with technical specifications expected by January 2027
Samsung unveiled zHBM, which stacks HBM directly above GPUs to shorten data paths and improve efficiency. It also showcased HBM4E with a 4nm base die, processing-in-memory technology, and next-generation zNAND-O for edge AI
The focus is shifting beyond raw memory bandwidth toward greater capacity, 3D integration, and more efficient data movement
