Abstract

A 24-year-old Wall Street prodigy, Leopold Aschenbrenner, has disclosed the Q1 portfolio adjustments for his fund, Situational Awareness LP. The fund's assets under management skyrocketed from $5.52 billion to $13.7 billion. The most significant move was a massive bearish bet on the semiconductor sector. The fund established $8.46 billion in put options, targeting chipmakers like NVIDIA ($1.6B in puts) and the VanEck Semiconductor ETF (SMH, $2B in puts). This bearish stance extended to Broadcom, Oracle, AMD, Micron, ASML, Intel, Corning, and TSMC. However, the fund made a selective bullish exception, adding shares and call options for memory chip maker SanDisk. The fund maintained its core bullish thesis on energy and AI infrastructure. Bloom Energy remained its largest long equity holding. It also increased stakes in cryptocurrency mining/data center firms like CleanSpark, Riot Platforms, Applied Digital, and IREN Limited, viewing them as providers of critical ready-to-use infrastructure—land, power, and grid permits—for AI expansion. The 13F filing was submitted one day late. Overall, the fund's strategy involves substantial bearish semiconductor bets while maintaining concentrated, high-volatility investments in selective tech, computing, and infrastructure plays aligned with AI growth.

On Monday Eastern Time, the eagerly awaited Q1 US stock portfolio adjustment report (13F) for the fund "Situational Awareness LP," managed by the much-watched Wall Street newcomer, 24-year-old Leopold Aschenbrenner, was finally released.

As described in our previous report, as the world's youngest manager of a mega-fund, Leopold Aschenbrenner foresaw the importance of AI infrastructure "logistics" as early as 2024, making significant investments in power, land, and infrastructure, propelling his fund to massive expansion in less than two years since its inception.

This belated report shows that the market value of the fund managed by Leopold Aschenbrenner has surged from $5.52 billion in the previous quarter to $13.7 billion—and just under two years ago, the fund's initial AUM was only $255 million.

Such a rocket-like surge in assets under management indicates that the "Situational Awareness" fund has clearly become a star fund highly sought after on Wall Street—in fact, Leopold Aschenbrenner's portfolio moves have already become one of the most closely watched sources for "copying homework" among Wall Street institutions and retail investors in recent quarters.

Let's take a closer look at what this Wall Street star has done in the first quarter of this year.

Heavily Buys Short Positions in Chipmakers

From this adjustment report, the most significant move made by Leopold Aschenbrenner in Q1 was heavily shorting chipmakers.

As of the end of Q1, the fund aggressively purchased put options with a notional value of up to $8.46 billion, covering numerous chipmaker stocks, including a $2 billion put option on the VanEck Semiconductor ETF (ticker: SMH) and a $1.6 billion put option on AI giant NVIDIA.

Massive Purchase of Chip Put Options

Additionally, the fund established put option positions on Broadcom, Oracle, AMD, Micron Technology, ASML, Intel, Corning, and TSMC.

These bearish options are not only among the fund's top five purchases for Q1 but also rank among its top five holdings. This undoubtedly highlights Leopold Aschenbrenner's pessimistic outlook on the prospects of chip stocks.

However, Leopold Aschenbrenner is not bearish on all chip stocks.

In Q1, the fund slightly increased its holdings of memory giant SanDisk by 80,000 shares and established a SanDisk call value option position worth $380 million, possibly hinting that it expects the memory boom to continue and that the fund is making selective bets within the semiconductor industry.

Still Heavily Betting on Energy and AI Infrastructure

As of the end of Q1, US biofuel company Bloom Energy (ticker: BE) remained Aschenbrenner's largest bullish bet on an individual stock. His fund holds 6.5 million shares of Bloom Energy, valued at $879 million, and holds 409,000 Bloom Energy call options with a notional value of $55 million.

Furthermore, Situational Awareness increased its holdings in cryptocurrency mining/data center operators CleanSpark (ticker: CLSK), Riot Platforms (ticker: RIOT), Applied Digital (ticker: APLD), and IREN Limited (ticker: IREN).

As we previously analyzed, Aschenbrenner's bet on Bitcoin miners is not for cryptocurrency speculation but for the ready-to-use land, power, and grid permits held by these miners. In the era of massive AI infrastructure expansion, these resources are equivalent to "ready-made" AI infrastructure, saving years of approval time.

A Belated 13F Report

It is worth noting that Aschenbrenner's 13F filing was originally due last Friday—according to regulations, all institutional investment management companies holding securities over $100 million must submit this disclosure document to the U.S. Securities and Exchange Commission within 45 days after the quarter ends—but Situational Awareness did not submit the report until Monday morning.

Typically, late or missed 13F filings can lead to civil penalties at the SEC's discretion, ranging from small fines to a maximum of $750,000.

However, investors' attention is certainly focused on Aschenbrenner's specific portfolio adjustments.

Overall, while he aggressively established semiconductor put option positions in Q1, his fund still holds a significant amount of highly volatile tech stocks and continues to make selective investments in computing, memory, and data center infrastructure. This adjustment trend might be worth investors' reference.

Claude Accused of Becoming Dumber by the Entire Internet, Anthropic Steps In to Reveal: It’s Not the Model That’s Tricking You

When users complained that Claude was "getting dumber," the root cause wasn't the AI model itself. In an official blog post, Anthropic clarified the critical difference between two key settings in Claude Code: Model and Effort. Model refers to the core "brain"—the fixed, trained weights of a specific AI (like Sonnet, Opus, or Fable). Changing the Model addresses *capability* ("can it do this?"), but its knowledge is static post-training. Effort, however, controls the AI's *approach and thoroughness* for a specific task. A higher Effort level instructs Claude to read more files, run tests, perform verification, and complete multi-step reasoning before responding, significantly increasing its "work output" for that job. Conversely, low Effort leads to quicker, less thorough replies. This distinction explains the March 2024 uproar where users experienced a sudden drop in Claude's performance. The cause was not a model change but Anthropic quietly lowering the *default* Effort setting from "high" to "medium" to reduce latency, which was later reverted. The key insight is that a smaller, capable model (like Sonnet) on high Effort can often outperform a larger, more powerful model (like Opus) on low Effort for many tasks. The article provides a practical troubleshooting framework: if Claude makes an error, first check the context and instructions. If it seems to skip necessary steps or validations, increase Effort. If it diligently attempts the task but fails conceptually or makes consistent factual errors despite good context, then consider switching to a more capable Model. The takeaway is a shift in focus: effective AI programming is less about always choosing the "strongest" model and more about intelligently *orchestrating* models and effort levels—acting like a project manager to assign the right "brain" with the right level of diligence for each job, optimizing both results and cost.

Will the Ethereum Foundation Evolve into a 'Mascot'? Diversified Organizations Are Fragmenting Its Functions

The Ethereum Foundation (EF) is undergoing significant internal turmoil and functional erosion. Following its largest-ever layoff of 54 staff (20% of its workforce) and a major organizational restructuring announced in June, its Protocol Support Team has been officially dissolved. This comes alongside the high-profile resignation of key figures like co-executive director Xiaowei Wang, bringing senior departures this year to at least eight. Criticism of EF's rigid structure, opaque decision-making, and perceived lack of a clear value narrative for ETH has intensified within the community. The layoffs have catalyzed the emergence of independent, non-profit organizations like Ethlabs and Ethereum Institutional, founded by former EF researchers and members. These entities are now taking on core functions such as protocol research/development and institutional adoption, effectively fragmenting the EF's traditional leadership role. Concurrently, EF's security team is adapting to technological change, deploying specialized AI agents to audit Ethereum's codebase, which successfully discovered a critical vulnerability (CVE-2026-34219). While EF states AI complements rather than replaces researchers, it signals a potential future shift in its operational model. Faced with these challenges—internal restructuring, talent drain, the rise of competing organizations, and AI integration—the Ethereum Foundation appears to be stepping back from a central commanding role. Analysts and community observers speculate it may increasingly transition towards a symbolic "ecosystem mascot" function, while decentralized initiatives drive Ethereum's future growth and institutional adoption.

Nearly a Hundred Players Rush into Embodied Data: With 4.47 Billion Yuan in Financing in One Year, Who Can Really Make Money by 'Selling Data'?

The domestic embodied AI data industry has attracted nearly 100 players, with 70 focused on data collection and 27 on data infrastructure. In the past year, 15 independent embodied data service providers raised approximately 4.47 billion yuan. Despite this growth, the sector remains early-stage, fragmented, and faces significant challenges. Data collection methods are diverse, categorized into four main routes: teleoperation of real robots, human demonstration without a robot (using motion capture, exoskeletons, etc.), simulation synthesis, and distillation from internet videos. Most companies (43%) adopt hybrid approaches, combining multiple routes, as no single method can meet all training needs. Teleoperation alone is pursued by 31% of players, often by state-owned platforms and robot companies, while newer firms favor asset-light, no-hardware human demonstration. Independent data service providers now form the largest player group (40%), indicating the emergence of a distinct industry segment rather than just a subsidiary function for robot makers. Two-thirds of all players are "embodied-native" startups, while one-third are companies that pivoted from fields like AI data annotation, which are more prevalent in the data infrastructure layer. Current annual industry capacity is estimated at 1.6-1.8 million hours plus 70-80 million data points, with a short-term goal to increase this 15-20 fold within 1-3 years. Data collection factories are spread across 20 provinces in China, concentrated in the Yangtze River Delta, Beijing-Tianjin-Hebei, and Pearl River Delta regions. Financially, the 4.47 billion yuan raised in the past year pales compared to the 43.8 billion yuan raised by the broader embodied intelligence sector in just the first half of 2026, highlighting that data remains a less "sexy" bet for investors. The 15 funded independent providers show clear stratification: a top tier led by a unicorn (Lightwheel Intelligence, 3.1 billion yuan), a middle tier of 11 firms raising tens to hundreds of millions, and an early-stage tier of 3 companies. Sixty-nine investment institutions have participated, but none have made concentrated bets, reflecting uncertainty about viable business models. Over half of these funded companies are less than a year old, most are at pre-A or A rounds, and profitability remains largely unproven. In summary, the embodied data industry has become an independent track creating jobs and local economic activity. However, it is still nascent, with unformed consensus, unsolved problems, and unproven business models. The coming 1-2 years will be a critical validation window to see if companies can build sustainable, profitable businesses purely by "selling data."
