Hedge Fund Citadel already held every stock in Leopold Aschenbrenner's book before buying it
Citadel's own quarterly filing, out Friday, already listed every stock in Leopold Aschenbrenner's book, about a month before it bought the book. The catch is what those holdings actually mean.
Riot Platforms (RIOT) postponed its earnings call. Six days later it announced a $9.1 billion AI lease
Riot pulled its August 5 call with no reason and no date, and the stock got punished for it. The rescheduled call landed a 20-year, 191 MW Rockdale lease with an unnamed frontier AI lab worth $9.1 billion, on interconnection Texas already approved before it froze the queue.
Meta backed Texas's data center audit. Its $10 billion El Paso project sits outside the grid Abbott froze.
Governor Abbott's office said Meta will comply with the state's data center standards. Meta's largest Texas campus is not on the ERCOT grid, and the Texas Tribune reported the same day that its Fort Worth and El Paso abatements ran through Delaware shell companies. CleanSpark, whose entire 885 MW Texas portfolio is inside ERCOT, backed the audit on its own.
Leopold Aschenbrenner sold 11.5 million Core Scientific (CORZ) shares below the Aug. 3 low. The stock closed up 10%.

Governor Greg Abbott ordered the PUCT and ERCOT to audit every data center seeking a grid connection, and new approvals are frozen until it is done. Bernstein says already-approved megawatts just got more valuable, and named Cipher (CIFR), CleanSpark (CLSK) and Core Scientific (CORZ) as the most exposed.
Nine Aschenbrenner stocks report earnings Aug. 4 to 6, led by SanDisk (SNDK). Nobody can say which six are still his.

Leopold Aschenbrenner's Situational Awareness fund owned 19 stocks outright. Every one of them rose Thursday after he sold his positions
Four SEC filings name 19 companies Situational Awareness owned outright, and every one of them rose on July 30. Nebius was the biggest at about $1.84 billion, and the quarterly report understates SharonAI by twelve times.
All seven Magnificent Seven stocks fell today. Here's where that money actually went (July 23, 2026)
All seven Magnificent Seven stocks were red by late morning Thursday, led by Tesla's 14% drop on an earnings miss and Alphabet's close-to-7% slide despite beating estimates, on another capex raise. Amazon and Meta sold off too ahead of next week's reports. The money didn't just leave, it rotated: into defense on Lockheed's earnings beat, and out of quantum, SaaS and space.
Cipher Digital (CIFR) is up 39% in two sessions, and its own AI news hasn't landed yet
Cipher Digital (CIFR) gained 39% in two trading sessions, but most of the credit belongs to Hut 8 and IREN's AI infrastructure deals. Cipher's own catalyst, its first AWS rent payment, doesn't land until August.
IREN signed $2.8 billion in AI contracts, and bitcoin miner stocks rallied with it
IREN closed up 19.6% after announcing $2.8 billion in new AI cloud contracts. Hut 8 and CleanSpark had data center lease news of their own, while CIFR, SLNH and KEEL rallied in sympathy. The fuel: Moonshot AI is turning away paying Kimi K3 subscribers because it ran out of GPU capacity.
I let Claude AI trade $100 on Robinhood, week 4: It's 0 for 4, then it passed on IREN's 17% jump, and watched it run higher
Claude AI is 0 for 4 with my $100 and the account is down to $74.59. On Monday it built an order for IREN at $39.45, then found that the same stock had popped on the same news back on July 6 and given back 23%, and walked away. IREN ran higher without it.
Nebius (NBIS) signed a $1 billion deal this week. Its stock is down 14% today anyway, worse than the chipmakers.
Nebius signed a $1 billion, multi-year AI compute deal with Reflection AI, and its stock is still down about 14% today. The pressure has spread well past chips: CoreWeave, crypto miners like IREN and Cipher Mining, power stocks like Talen Energy and Vistra, and now New York's data-center moratorium and a Trump-Hochul clash are all weighing on the same trade.
Bitcoin miners are becoming AI landlords. Here's how far each one has actually gotten.
Eight bitcoin miners are pitching the same AI pivot, but they're nowhere near equally far along. IREN and TeraWulf already have AI revenue flowing. Hut 8, Cipher and Applied Digital have billions in signed leases that haven't started billing yet. CleanSpark still just mines bitcoin.
TeraWulf, CoreWeave, and Nebius are having a big day. The stocks still mostly mining bitcoin are not.
TeraWulf, Nebius, IREN, CoreWeave, and five other AI infrastructure stocks are surging together Wednesday, while HIVE Digital and CleanSpark, the two names still mostly mining bitcoin, are red. The split isn't random.

The same Meta cloud announcement that sent META up about 10% on July 1, 2026 is hammering the neoclouds. CoreWeave (CRWV) and Nebius (NBIS) each fell about 13% as investors saw a giant new rival for renting out AI computing power.
Bitcoin is sliding, and the AI data center miners are sliding with it (IREN, CORZ, CLSK)
A dozen former bitcoin miners now call themselves AI data center companies. With bitcoin down near $58,300 and sliding a second day, most fell with it, while the names furthest from crypto held up best.
Data-center and bitcoin-miner stocks (CRWV, HIVE) sold off at the open on June 29 after a pre-market pop
AI data-center, neo-cloud, and bitcoin-miner stocks ticked up pre-market on June 29, then sold off hard at the open. Most are down 3% to 10% from the open and now slowly recovering. Nebius (NBIS) was the exception.
HIVE Digital (HIVE): a green bitcoin miner pivoting to AI, and a Leopold Aschenbrenner pick
HIVE Digital (HIVE) is the cheap, green bitcoin miner betting on AI. A look at the BUZZ HPC pivot, the recent $300 million share program, the Leopold Aschenbrenner stake, and the full bull and bear case.
IREN bought the Warriors' jersey patch. Here's how it stacks up against WULF, CIFR and the other ex-miners
A few years ago IREN was a bitcoin miner. Now its badge is going on every Golden State Warriors jersey in a deal worth more than $50 million a year. Here is what IREN actually does, the Microsoft and Nvidia contracts behind the splash, and how it compares to ex-miners like WULF, CIFR, APLD and CLSK.
