ARK's Massive Buying Spree in Crypto-Linked Stocks: Lower Risk, or Double the Pressure?

ARK Invest, led by Cathie Wood, significantly increased its holdings in crypto-related public stocks in June, purchasing $77 million worth of shares in Coinbase, Circle, and Bullish during Bitcoin's worst monthly performance in four years. The investment thesis is that these stocks offer regulated exposure to the crypto cycle without direct Bitcoin ownership. However, data analysis reveals significant downsides: these stocks exhibit nearly double the volatility of Bitcoin (68%-90% vs. 37.6% 30-day annualized volatility) and carry substantial company-specific risks like earnings, competition, and equity dilution, which account for much of their price movement. Only MicroStrategy closely tracks Bitcoin, acting as a leveraged proxy. Coinbase shows moderate correlation, while Circle and Robinhood have low correlation, being more influenced by stablecoin competition and diversified brokerage operations, respectively. Mining companies like RIOT and MARA have surged due to AI-related ventures, decoupling from Bitcoin's price. The case of Strategy highlights additional equity-structure risks, such as potential value erosion when its market value falls below its net asset value. Ultimately, investing in crypto stocks often means accepting amplified Bitcoin volatility or layering on unrelated business risks, rather than obtaining a safer alternative to direct cryptocurrency ownership.

Karpathy's Latest Outburst: A Single Sentence That Silenced the Entire Agent Developer Community

Andrej Karpathy, a core researcher at Anthropic, recently critiqued the current AI agent development frenzy. He argues that the biggest mistake is forcing agents to perform tasks without first thoroughly understanding the underlying large language models. Drawing from his 2016 "World of Bits" project at OpenAI—an early attempt at web-based agents that ultimately failed due to premature technology—he emphasizes that foundational model work is crucial. Karpathy offers three key pieces of advice: First, focus on getting the base models right before pushing agents. Second, recognize that creating a demo is easy, but building a real product takes a decade, akin to the journeys of autonomous driving and VR. Third, the product is the core capability, not the agent shell; a robust foundation will naturally enable advanced agents. He also suggests looking to neuroscience for inspiration, comparing agent components to brain structures like the hippocampus and thalamus. Despite his caution, Karpathy concludes that independent developers and startups, not large labs like OpenAI, are at the forefront of agent innovation. This is because the agent field is new, with no entity having a five-year head start, leveling the playing field for agile experimenters. His core message is not to abandon agent work, but to build it on a solid, deeply understood foundation.

Is altcoin season here? Why Bitcoin’s $21B OI says not yet

While Glassnode's Altcoin Cycle Signal suggests altcoins are outperforming Bitcoin overall, indicating the start of an altcoin season, analysis of Open Interest (OI) presents a counterpoint. Bitcoin's OI stands at $21.11 billion, significantly higher than the $16.36 billion for altcoins. This signals that trader focus and capital inflows remain concentrated on Bitcoin, implying the broader altcoin market may still have room for expansion. Historically, altcoin rallies have often peaked when their OI surpasses Bitcoin's. Analysts note Bitcoin is holding support around $58,000, with selling pressure potentially fading. Some view the current Bitcoin price as an attractive long-term entry point, contingent on factors like Federal Reserve policy. However, as long as Bitcoin continues to dominate capital flows and the altcoin index remains below a key threshold, the market is seen as being in a Bitcoin-led phase rather than a full-blown altcoin season. The consensus is that a broad rotation into altcoins has not yet fully materialized.

After Close Observation of Wash, Morgan Stanley's Chief Economist Insists: The Fed Will Not Raise Rates This Year

After close observation of Federal Reserve Chair Wash, Seth Carpenter, Morgan Stanley's Chief Global Economist, asserts that the Fed will not raise interest rates this year. Following Wash's speech at the ECB's Sintra forum, Carpenter notes a marginal dovish shift: Wash now more clearly balances the Fed's dual mandate of price stability and maximum employment, rather than focusing nearly exclusively on inflation. Importantly, Wash highlighted that the latest policy meeting (coinciding with falling oil prices) has already lowered market inflation expectations and term premiums, signaling no urgency for a July rate hike. Carpenter's view is supported by data. Recent non-farm payroll figures provide room for the Fed to remain patient. Morgan Stanley's inflation forecasts are below the median FOMC projection, and methodological revisions to PCE inflation could further lower readings. These factors make Carpenter "comfortable" with the call for no hikes in 2024. Carpenter also pushes back against the simplistic narrative that AI will be deflationary and lead to rate cuts. He argues AI investment is currently boosting inflation marginally. More broadly, the business cycle will dictate policy; AI's productivity gains could boost demand and, crucially, raise the equilibrium interest rate (r*), weakening the case for cuts. In contrast, the ECB's path remains more hawkish. Carpenter interprets President Lagarde's Sintra comments as leaving the door open for another 25 basis point hike in September, though softer recent data and falling oil prices provide some flexibility. A July hike or more than one additional hike this year is seen as unlikely.

U.S. Stock Market Trend (July 6th): Gold and Crypto Lead Rebound Ahead of Stocks, Fed Minutes Set Weekly Direction

**U.S. Market Trends (July 6): Gold & Crypto Lead, Fed Minutes to Set Tone** Markets rebounded ahead of the U.S. Independence Day holiday, with Nasdaq 100 futures rising over 1% as AI sector concerns eased. Gold posted its best week in over a month, breaking a four-week losing streak despite ongoing Russia-Ukraine tensions, as Middle East risk premiums faded. Brent crude extended its decline for a fourth week. The week ahead is packed with key events. On Tuesday, SpaceX makes a record-fast entry into the Nasdaq 100 index, forcing passive fund flows, while U.S. tariff hearings and the Sun Valley Conference—notably missing NVIDIA's Jensen Huang and Tesla's Elon Musk—add complexity. OpenAI's scheduled GPT-5.6 release intensifies the AI model rollout race. The main focus is Thursday's release of the first Fed meeting minutes under Chair Wash. With half the FOMC already leaning toward a rate hike this year per the June dot plot, the minutes' tone will be critical for market direction. Hawkish confirmation could reverse recent risk-on sentiment, likely signaled first by a pullback in high-volatility assets like Bitcoin and Ethereum, which significantly outperformed last week. Other events include SK Hynix's large U.S. ADR listing and the start of the Q2 earnings season with reports from PepsiCo and Delta Air Lines. The market's path hinges on whether the liquidity and optimism built during the holiday can withstand the combined tests of Fed policy, trade tensions, and major corporate events.

Meta Joins the 'Selling Shovels' Game, Zuckerberg: 'Models Can Be Slow, but GPUs Must Earn'

Meta pivots to selling AI infrastructure as internal model development lags. Facing setbacks like Gemini usage restrictions and slower-than-expected progress on its own AI agents, the company is reportedly launching "Meta Compute." This service would rent out its massive GPU capacity and data center resources—projected to reach over 10GW—to external clients. The move mirrors SpaceX's "neocloud" model, offering high-margin, flexible compute contracts. Meta also plans to host third-party models like Anthropic's Claude, creating a platform similar to Amazon Bedrock. This strategy provides immediate revenue while its in-house models (like the upcoming "Watermelon") continue development. Wall Street reacted positively, seeing it as a way to monetize heavy AI investments even if Meta's models aren't yet industry-leading.

World's Largest Data Center Project Scrapped

Blackstone Abandons Plans for World's Largest Data Center, Signaling Wider AI Infrastructure Headwinds Blackstone has halted construction of its massive "Digital Gateway" data center campus in Virginia, which was planned to be the world's largest. The project's cancellation follows a five-year battle with local residents concerned about historical preservation, environmental impact, and strain on local resources. A procedural error in the zoning approval process ultimately led a state court to invalidate the project's permits. This move comes shortly after Blackstone sold other mature data center assets, suggesting a strategic pivot by the asset management giant. Industry analysts see this as a potential sign of "peak" investment enthusiasm, mirroring Blackstone's past exits from overheated sectors like office real estate. The cancellation highlights significant bottlenecks facing the AI-driven data center boom across the U.S. Key challenges include severe power grid constraints, with data centers' electricity demand projected to triple nationally by 2035, and mounting grassroots opposition. A report notes over $130 billion worth of U.S. data center projects were delayed in Q1 2026 alone, primarily due to power shortages and community resistance. Local and state governments are also beginning to implement stricter regulations, including new taxes and moratoriums on construction. Blackstone's exit underscores that the breakneck expansion of AI infrastructure is colliding with practical limits, from physical resource caps to social license, forcing a more realistic assessment of costs and feasibility.

OpenAI Proposes Transferring 5% Equity to the U.S. Government

OpenAI has reportedly proposed to sell 5% of its equity to the U.S. government, a stake valued at over $40 billion based on its $852 billion valuation. According to the Financial Times, CEO Sam Altman has engaged in preliminary discussions with senior officials, including the Commerce and Treasury Secretaries, framing public ownership as a way for Americans to share in AI's economic benefits. The proposal includes a broader vision where other major U.S. AI companies like Anthropic, Google, and Meta would contribute a similar percentage of their equity to a public investment vehicle, modeled on the Alaska Permanent Fund, to distribute dividends to citizens. However, there is no indication of interest from these rivals. This move is seen as an attempt to navigate increasing regulatory pressure and scrutiny over AI safety and societal impact. It contrasts with more radical proposals, such as one from Senator Bernie Sanders advocating for up to 50% public ownership. While the discussions are conceptual and would likely require congressional action, they signify a strategic shift: OpenAI is offering a financial stake to align government interests and potentially secure a more stable regulatory relationship ahead of a possible future IPO. The outcome could reshape how AGI development is governed and who benefits from its profits.
