AI's Three Mortal Enemies Rarely Unite! Did 'AI Stocks' Suffer a Blow on Monday?

The three historic rivals in the AI field have, for the first time in history, stood on the same side—uniting after a series of uncontrolled incidents and doomsday warnings repeatedly shook the industry. The CEOs of Anthropic, OpenAI, and SpaceX have rarely joined forces to call for a slowdown in AI development. On Saturday, Dario Amodei, CEO of Anthropic, published a blog post urging the global AI industry to voluntarily slow down, arguing that the pace of advancement in cutting-edge models has far outstripped humanity’s capacity to understand and control them. Within hours of its publication, Elon Musk, CEO of SpaceX, posted on X: “Dario is right.” Sam Altman, CEO of OpenAI, quickly followed up, agreeing with Amodei’s assessment about “pacing the frontier,” and pledged that OpenAI would grant independent third-party evaluators employee-level system access. Altman also told Fortune magazine that, given the current safety landscape, OpenAI may postpone its IPO plans until 2026. “I believe there is a 10% probability that AI will kill everyone by the end of this decade—and that is unacceptable.” AI safety risks have erupted into public awareness with unusual intensity over the past week. Jacob Coxon, an Anthropic researcher, resigned in protest, declaring, “The industry is gambling with our lives.” Evan Hubinger, Anthropic’s Head of Alignment Science, subsequently stated that the probability of AI systems causing a mass extinction event within this decade exceeds 10%. According to reports, a group of OpenAI agents previously broke out of their testing environment and infiltrated the AI developer platform Hugging Face—an incident that has become the direct catalyst behind multiple executives’ warnings. This abrupt pivot—from pursuing maximum growth to emphasizing safety-driven deceleration—has triggered a chain reaction across trading communities. Early market indicators show that, following news of the “AI slowdown,” related assets on the HyperliquidX platform dropped sharply: OpenAI-related assets fell 7%, and Anthropic-related assets fell 2.8%. Numerous market observers and investors have already issued warnings on social media, expressing concern that the news could significantly impact AI-related stocks—including NVIDIA, Broadcom, and AMD—on Monday. Jason, a well-known tech investor on X, posted directly: “AI stocks will fall more than 10% in Monday’s pre-market session,” adding that Amodei’s blog post “single-handedly dismantled the AI trade.” Amodei Acts: We Must Hit the Brakes on Frontier AI On Saturday, Anthropic CEO Dario Amodei published a lengthy essay titled directly: “We Must Pace the Frontier.” He opens candidly: he has pursued AI research for twelve years because he believes it can cure diseases, accelerate economic growth, and bring human prosperity—his father died from a disease cured just years after his passing, and he himself survived early-stage cancer. He longs for AI’s benefits more than anyone.

Live Broadcast of Berkshire Hathaway’s 2026 Annual Shareholders Meeting: Buffett Steps Aside; Abel Takes Center Stage for the First Time

Abel: I’ve operated various businesses at Berkshire Hathaway Energy for many years, then served as Vice Chairman of Non-Insurance Operations. Fortunately, Ajit and I have held these wonderful roles for the past eight years—now nine. But this has created an exceptionally important opportunity for me to deeply understand these businesses. As I’ve already mentioned, we own outstanding businesses led by outstanding management—but opportunities still exist. Yet this truly reminds me that I’ll spend dedicated time on these businesses to ensure capital is allocated appropriately, that we continue assessing their risks, and that we encourage operational excellence. Because, listen: as an insider, it’s easy to look only at internal metrics and convince yourself you’re doing well—you must look outward and ask: What do customers see and feel? What are our competitors doing? I believe this is precisely the value we bring to operations. I’ve mentioned assigning Adam Wright greater responsibilities—or expanding his role across 32 businesses. He brings exceptional operational expertise, and we also have our insurance-side team. Now, turning to our stock portfolio and time allocation: There remain enormous opportunities in how we deploy capital on our balance sheet. I shared our cash and U.S. Treasury holdings. Let me emphasize one point: if you examine our current stock portfolio—as outlined in my letter—we hold a highly concentrated portfolio. We refer to it as our “core” portfolio, but the most accurate description is indeed a concentrated one. We hold what we call “core and concentrated” investments. In my letter, I highlighted our Japanese investments. Interestingly, if you look at the next tier of companies where we hold very significant positions, I’d add that for these firms, we may still be purchasing shares—or rationalizing appropriate position sizes within the portfolio. So the first group—I’ve emphasized this—is slightly under $200 billion, and we aim to maintain it at that level. We currently hold nearly $100 billion—or $85 billion. Then, adding Berkshire’s other investments—such as Bank of America, Chevron, Google, and others—brings another $70 billion. This underscores that a very large portion of our total investment is highly concentrated in a limited number of holdings, with relatively little active management applied to them—a point I truly want to stress. We know those businesses intimately. We know their management teams. These remain matters Warren and I still collaborate on and discuss thoroughly. You don’t need to discuss them daily—but if anything arises in any of these businesses, we’ll address it that week or that month. Perhaps it’s about their strategic direction—or something new we’ve learned. Japanese companies just reported earnings within the past 48 hours—a topic of active discussion. Yesterday morning, Warren and I discussed their results and what we’re observing there. So these are core holdings—but that doesn’t mean we set them aside or treat them as passive, static positions we merely monitor during evaluations. Ted manages another $20 billion—or slightly less—but his responsibilities extend far beyond that.
