Executive Summary
The AI hardware sector reached a new peak of investor frenzy as Cerebras Systems, a startup building wafer-sized chips, closed its first day of public trading with a valuation just shy of $100 billion, raising $5.55 billion. The staggering debut came as global bond markets suffered a sharp selloff, sending yields soaring and dragging down stocks, with the S&P 500 falling more than 1% as the 10-year Treasury yield climbed above 4.5%. The financial turbulence was exacerbated by oil prices surging past $105 a barrel, a spike fueled by the lack of a diplomatic breakthrough on the Strait of Hormuz crisis following a summit between President Donald Trump and China’s Xi Jinping. That meeting, while heavy on ceremony, yielded little concrete progress on Taiwan or Iran, even as Trump later claimed Xi had pledged to halt military aid to Tehran—an assertion Beijing has not confirmed.

Cerebras IPO Nears $100 Billion Valuation, Challenging Nvidia
Cerebras Systems completed a blockbuster initial public offering on Thursday, closing its first day of trading with a market capitalization just below $100 billion. The company, which builds artificial intelligence chips the size of dinner plates, raised $5.55 billion in one of the largest tech IPOs on record. Its stock traded lower on Friday, its first full day on the Nasdaq.
The milestone caps more than a decade of development on a radically different approach to chipmaking. Unlike Nvidia’s graphics processing units, which are cut from silicon wafers and assembled, Cerebras’s Wafer-Scale Engine is a single, monolithic chip measuring 46,225 square millimeters. “Big chips process more information in less time,” Andrew Feldman, the company’s co-founder and CEO, told CNBC. The chips are designed as custom application-specific integrated circuits optimized for the complex math used in AI training and, increasingly, for inference, where models make decisions based on new data. The massive valuation signals intense investor appetite for alternatives to Nvidia, whose GPUs have been in short supply as tech giants scramble to build AI infrastructure. Cerebras now operates in an increasingly crowded field that includes custom AI chips developed in-house by Google, Amazon and Meta.
Anthropic Secures $30 Billion at $900 Billion Valuation Amid Soaring Revenue
The AI lab Anthropic has agreed to terms on a $30 billion funding round that would value the company at $900 billion, according to a report in the Financial Times. The deal, co-led by Dragoneer, Greenoaks, Sequoia Capital and Altimeter Capital, would nearly triple the company’s valuation from just three months ago. The round came together rapidly after CFO Krishna Rao initiated talks with backers only a fortnight ago, capitalizing on a staggering revenue surge that saw the company’s annualized run-rate jump from $19 billion in March to $30 billion in April.
CEO Dario Amodei told a developer conference earlier this month that Anthropic had planned for 10x growth this year but instead achieved 80x, a pace so fast that its own infrastructure has struggled to keep up. This explosive performance explains why employees largely refused to sell their shares in a secondary tender offer earlier this year priced at the old $350 billion valuation. The company is now in early talks with Goldman Sachs, JPMorgan and Morgan Stanley for an IPO that could raise more than $60 billion as soon as October. Anthropic’s new valuation would leapfrog its rival OpenAI’s recent $852 billion valuation, intensifying the competition between the two leading AI labs.
Trump and Xi Discuss AI Guardrails, Leaving Nvidia’s China Business in Limbo
President Donald Trump concluded a state visit to Beijing this week where he and Chinese President Xi Jinping discussed establishing “guardrails” for artificial intelligence, a term Trump described as standard. The talks also touched on the stalled approval of Nvidia’s H200 AI chips for the Chinese market, with Trump suggesting “something could happen,” while Chinese officials reiterated their opposition to export controls without providing specifics. Nvidia’s stock surged 4.4% on Thursday and is up 20% since May 5, nearing a $5.7 trillion market capitalization, as traders bet on a potential reopening of chip sales to China ahead of the company’s earnings report next Wednesday.
These high-level discussions occur amid intensifying pressure from U.S. AI firms, notably Anthropic, for Washington to tighten export controls further. In a public post, Anthropic argued that democratic nations have a limited window to act before China catches up, claiming Chinese labs have closed the gap to within months of U.S. capabilities by exploiting loopholes. This push for stricter controls conflicts with other industry voices, such as OpenAI’s Chris Lehane, who has called for a global governance system that could include China. The Commerce Department estimates that China’s leading model, DeepSeek V4 Pro, is only about eight months behind the U.S. frontier, underscoring the perceived narrowness of the American lead.
Geopolitics & Security
Trump-Xi Summit Yields Ceremony Over Substance on Taiwan and Iran
President Donald Trump returned from a summit with Chinese President Xi Jinping facing criticism that he conceded geopolitical ground to Beijing, even as he touted commercial agreements. The meeting, described by Chinese state media as “historical” and a “landmark,” produced few substantive breakthroughs but highlighted the deep interdependence and growing mistrust between the two powers. During the flight home aboard Air Force One, Trump revealed that Taiwan was a central topic, disclosing that Xi spoke emotionally about the island, saying China had possessed it “for thousands of years and then at a certain period of time it left and we’re going to get it back.” Trump said he made “no commitment either way” on future U.S. arms sales to Taiwan, a stance that alarmed critics who saw it as a departure from long-standing U.S. policy.
On Iran, Trump claimed that Xi promised not to provide military equipment to Iran and wanted to help reopen the Strait of Hormuz, but Chinese officials have not confirmed any new policy positions. The Chinese foreign ministry, in its readout, reiterated that Taiwan is “China’s internal affair” and made no mention of Iran. Analysts concluded that Beijing emerged with a strategic victory, securing the international optics of equality with Washington. Some commentators described the summit as a potential “Suez moment” for America, a reference to the 1956 crisis that marked the symbolic end of British imperial primacy.
Russia and Ukraine Escalate Drone War, Striking Civilian Apartment Blocks
Russia and Ukraine exchanged massive aerial barrages this week, with strikes killing civilians in apartment buildings in Kyiv and Ryazan. Russian forces launched more than 1,500 drones and dozens of missiles at Ukraine over several days, culminating in a cruise missile strike on a nine-story Kyiv apartment block that killed at least 24 people, including three children. Ukraine responded with a large-scale drone attack on Russia, striking an oil refinery in Ryazan and hitting residential buildings there, killing three people, according to Russian officials.
The scale and civilian toll of the attacks mark a grim escalation in a conflict increasingly defined by long-range drone and missile warfare. Ukrainian President Volodymyr Zelenskyy, who visited the Kyiv strike site, said the weapon used was a recently manufactured Russian Kh-101 missile, indicating that international sanctions have not fully crippled Russia’s ability to produce advanced munitions. The Council of Europe announced it is moving to establish a special tribunal to try Russia’s leadership for the crime of aggression, a direct response to the ongoing bombardment of civilian infrastructure. The reciprocal attacks on residential buildings suggest a deliberate targeting of civilian areas, a tactic both sides have employed but which Russia has used on a far larger scale throughout the invasion.
NATO and Japan Accelerate Military Spending Amid U.S. Pressure
NATO Secretary-General Mark Rutte will convene a rare meeting with Europe’s top defense executives next week to press for increased investment and production, particularly in air defense and long-range missiles, according to people familiar with the matter. The push is aimed at appeasing U.S. President Donald Trump’s demands for higher allied spending and reducing European reliance on American military support. Companies including Rheinmetall, Airbus and Saab are expected to attend, though several firms declined to comment on the private meeting.
This industrial mobilization coincides with significant national defense initiatives across the globe. Japan’s ruling Liberal Democratic Party is debating a proposal to raise defense spending to as much as 5 percent of GDP, a sharp increase from its historical 1 percent level, driven by pressure from Trump and worsening security in the Indo-Pacific. Meanwhile, the U.S. Navy’s new 30-year shipbuilding plan, released this week, calls for funding the first of a new class of 11 nuclear-powered guided missile battleships starting in fiscal 2028, a revival of a long-dormant ship type. Not all military expansion is welcoming American technology. Germany’s Bundeswehr has definitively excluded Palantir, the U.S. data analytics firm, from a major software contract, with Vice Admiral Thomas Daum stating that granting a private American company access to Germany’s national military database is “simply inconceivable.”
Trump Considers Renewed Strikes on Iran as Diplomacy Stalls
President Donald Trump returned from his summit with Xi Jinping facing mounting pressure over the Iran war, with top aides preparing options for renewed military action against Tehran if diplomacy fails. According to a New York Times report, Pentagon officials have drafted plans for a possible resumption of strikes under a renewed campaign after “Operation Epic Fury” was paused during an April ceasefire. One option reportedly involves deploying U.S. Special Operations troops to secure highly enriched uranium believed to be stored deep underground at Iran’s Isfahan nuclear facility, a mission officials acknowledged would carry “big risks of casualties.”
Simultaneously, diplomatic channels are active but strained. Trump claimed after his meeting with Xi that “we control the Strait of Hormuz,” and said Xi “feels strongly” that Iran should not have a nuclear weapon and wants the strait opened. However, Iran’s Foreign Minister Abbas Araghchi said his country “cannot trust the Americans at all” and accused the United Arab Emirates of being “directly involved in the aggression.” At a BRICS meeting in India, Araghchi urged the bloc to condemn the U.S.-Israel war as a violation of international law. Iran allowed more than 30 ships, including some linked to Chinese companies, to transit the Strait of Hormuz overnight, signaling the waterway was “open to all commercial ships” that cooperate with Iranian naval forces.
Economy & Markets
Global Bond Selloff Sends Yields Soaring, Oil Tops $105
A sharp global bond market selloff on Friday sent yields soaring and triggered a 1% drop in the S&P 500, led by technology shares, threatening to end Wall Street’s recent risk rally. The 10-year U.S. Treasury yield climbed above 4.5%, Japan’s 30-year borrowing costs hit 4% for the first time, and yields on U.K. long bonds reached a 28-year high, driven by persistent inflation anxiety and a fresh geopolitical shock that pushed oil prices above $105 a barrel.
The simultaneous surge in yields across major economies reflects a market reassessment of the inflation outlook and the potential for central banks to keep interest rates higher for longer. The spike in oil prices, following the Trump-Xi summit that produced no breakthrough over the Strait of Hormuz standoff, added immediate fuel to inflation fears. This combination of rising borrowing costs and energy prices directly pressures corporate profits and the valuation of growth-oriented technology stocks. Analysts at JPMorgan and other major banks have warned that the equity rally was becoming increasingly detached from the sobering message of the bond market.
SpaceX IPO Filing Imminent, Sparking Bubble Fears
SpaceX is reportedly preparing to file for an initial public offering as soon as next week, a move that could value Elon Musk’s rocket and satellite company between $1.75 trillion and $2 trillion. CNBC’s Jim Cramer warned Friday that the highly anticipated debut, expected in June, could be “destructive” for the broader market by fueling speculative excess, similar to the recent blockbuster IPO of AI chipmaker Cerebras Systems. He cautioned that if underwriters release too few shares, SpaceX’s valuation could quickly balloon, creating “a bubble unto its own.”
Separately, the Financial Times reported that the IPO is set to lock in Musk’s control through a Mars-linked pay deal, a structure that has drawn scrutiny from major institutional investors. New York State Comptroller Thomas DiNapoli, who oversees the state’s pension fund, has previously raised governance concerns about Musk’s companies, arguing that tying executive compensation to long-term, speculative goals like colonizing Mars can conflict with fiduciary duties to shareholders. The company did not immediately comment on the IPO timing or the pay structure. In a related commercial dispute, Delta Airlines publicly rejected Musk’s claim that it chose Amazon’s satellite internet service over SpaceX’s Starlink because Starlink prohibited a customer login portal. In a statement, Delta said Musk’s “assertion is not accurate.”
From the Timeline
Political Tensions and Geopolitical Strategy
Geopolitical strategy and alliances were a major focus, with commentary on U.S. foreign policy and military tech. @zerohedge highlighted a Trump statement suggesting the U.S. might not need to keep the Strait of Hormuz open, while @chamath showcased autonomous sea drones being deployed to the region for mine-sweeping, framing it as a critical kinetic capability. The reliability of U.S. alliances under a potential Trump administration was questioned by @Noahpinion, who agreed with an assessment that allies like Taiwan should be wary, advocating for increased drone and nuclear armament.
The AI Stack and Economic Value Creation
A significant thread dissected the structure and economic logic of the AI industry. @chamath provided a detailed framework for the AI stack, from physical infrastructure to applications, arguing that all revenue originates at the application layer. This focus on pragmatic value creation was echoed by @paulg, who reiterated a foundational principle for wealth creation: “just to make something people want,” implicitly critiquing political narratives around how people get rich. Meanwhile, @EMostaque argued that the economic impact of physical, humanoid robotics could far surpass that of digital AI, suggesting a massive, untapped TAM.
Regulatory and Policy Backlash
Experts voiced strong concerns about specific government regulations, seeing them as existential threats to tech and privacy. @tobi warned that Canada’s proposed C-22 bill could destroy tech viability by forcing services like VPNs to log user data, a point he and others reinforced in multiple posts. In a similar vein, @garrytan criticized San Francisco’s “Overpaid CEO Tax,” arguing it functionally taxes consumers via grocery stores and pharmacies while exempting large tech firms, calling it “bad anti-business policy.”
Critiques of DEI and “Leftist” Morality
A contentious theme involved critiques of Diversity, Equity, and Inclusion (DEI) initiatives and associated political morality. @elonmusk directly attacked DEI criteria for Academy Awards eligibility, framing it as a corruption of artistic merit. This sentiment was extended by @pmarca, who sarcastically redefined “DEI” to stand for “Datacenter, Electricity and Infrastructure,” redirecting the acronym toward tech infrastructure. In a separate post, Musk endorsed a critique that the “fundamental moral flaw of the left” is misplaced empathy for criminals over victims.
AI Product Realities and User Frustrations
Beyond grand frameworks, discussion also centered on the immediate user experience and limitations of current AI tools. @levelsio expressed frustration with the slow speed of Claude Code, threatening to switch providers despite a preference to stay. On the infrastructure side, @ClementDelangue pitched Hugging Face Storage as a solution for AI teams tired of choosing between expensive object storage and cumbersome git workflows. @sama noted his team takes user performance reports seriously, even when they stem from users getting “used to the current level of magic.”
The “Nakba” Debate and Campus Reckoning
A sharp cultural and historical debate unfolded around the commemoration of the Nakba. @wolfejosh vehemently rejected the narrative presented by New York City’s mayor, calling the Nakba a “failed genocide against jews” and accusing Palestinians of perpetual violent intent. This clash of narratives was juxtaposed with observations about American institutions, as @Noahpinion highlighted a projected 15% drop in freshman enrollment at the University of Vermont as part of a broader “reckoning” for American colleges.
Founders on Product, Infrastructure, and Speed
Founders shared insights on product development and the tangible impact of infrastructure. @dhh celebrated the return to high-speed, low-latency internet after experiencing rural connectivity, emphasizing its transformative effect on modern, CDN-heavy web use. @brian_armstrong reflected on Coinbase’s 14-year evolution from a simple Bitcoin wallet to a broad financial services platform, underscoring the goal of building for an open financial system. @benthompson criticized United Airlines’ management decision to forgo WiFi on some long-haul flights during a transition to Starlink, calling it unacceptable for customers.
