Cerebras Systems, the AI chipmaker that surged 68% in its Nasdaq debut Thursday, gave back gains Friday as investors locked in profits after the explosive IPO. The stock opened at $55 and closed at $32.48, a sharp reversal that reflects the unsustainable momentum in semiconductor stocks this week. The pullback signals that while AI infrastructure demand remains real, valuations have gotten ahead of fundamentals—a warning sign for the broader tech rally.
Brent crude futures surged 1.5% to $106.79 Friday as the Trump-Xi summit ended without progress on reopening the Strait of Hormuz, the critical shipping route that has been blockaded since February. WTI crude climbed 1.1% to $103.28. The International Energy Agency reported that crude and fuel flows through the Strait fell by around 4 million barrels per day in March and April, and warned that the global oil market could remain materially undersupplied through October even if the conflict is resolved next month. Trump warned Iran to reach a deal or face "annihilation," but Tehran's latest ceasefire proposal was rejected as "unacceptable." The persistence of high oil prices is the single biggest threat to the Fed's ability to cut rates, as energy-driven inflation will keep headline CPI elevated and sticky.
The 10-year Treasury yield climbed 15 basis points to 4.54% Friday, breaking above the 4.5% level for the first time in a year, as investors repriced expectations for Fed rate cuts. The 2-year yield rose 6 basis points to 4.09%, and the 2s/10s spread widened to 45 basis points, still inverted but less so. The yield spike reflects growing conviction that the Fed will hold rates steady through year-end and potentially hike in 2027 if inflation doesn't cool. Markets have now fully priced out any possibility of a Fed rate cut this year, with some traders increasingly betting on a potential rate hike by December. The rise in yields is a direct headwind for growth stocks and rate-sensitive sectors like real estate and utilities, which explains Friday's broad-based selloff in tech and discretionary names.
Starbucks announced Friday that it will lay off 300 US corporate employees and close some regional support offices, resulting in $400M in restructuring charges. The company expects to record $280M in noncash charges tied to asset impairments and $120M in cash charges related to the layoffs. This is the third round of job cuts under CEO Brian Niccol, who took over last year and has been aggressive in cutting costs. Last year, Niccol announced 1,100 job cuts and unfilled roles; seven months later, Starbucks announced another 900 job cuts as part of a $1B restructuring plan. Starbucks shares fell 0.69% in premarket trading Friday. The cuts signal that even consumer-facing companies with strong brand equity are feeling pressure to improve margins amid inflation and slowing consumer traffic.
South Korea's benchmark Kospi index fell more than 6% Friday, retreating from a fresh record high after briefly breaching 8,000 earlier in the session. The small-cap Kosdaq fell more than 5% to 1,129.82. The decline follows the Kospi's record-breaking streak, which has raised concerns over concentration risks, particularly in artificial intelligence stocks. The selloff mirrors the broader Asia-Pacific decline as investors reassess valuations after the Trump-Xi summit ended without major breakthroughs. South Korea's tech-heavy index is particularly vulnerable to profit-taking after a sharp rally, and the 6% drop signals that institutional investors are rotating out of the most crowded trades.
President Trump departed Beijing Friday after a two-day summit with Chinese President Xi Jinping that yielded no major policy breakthroughs on trade, Taiwan, or the Iran conflict. Trump claimed "fantastic" deals were made and "a lot of different problems" were resolved, but no concrete agreements were announced. Xi warned that mishandling Taiwan could lead to "clashes and even conflicts," signaling that the core geopolitical tensions remain unresolved. The market had priced in optimism that Trump's visit would ease US-China tensions and potentially unlock Chinese pressure on Iran to reopen the Strait of Hormuz—a critical shipping route that has been effectively closed since February, disrupting 4-6 million barrels per day of global oil flows. Instead, the summit's lack of tangible outcomes means investors must accept that the Iran war will likely persist through the second half of 2026, keeping oil prices elevated and inflation pressures alive. This directly undermines the Fed's ability to cut rates, as energy-driven inflation will remain sticky. The market repriced accordingly: the S&P 500 fell 1.1%, tech stocks sold off sharply (Nasdaq -1.5%), and Treasury yields spiked to their highest levels in a year as traders abandoned hopes for near-term rate cuts.
💡 The Strait of Hormuz is a narrow waterway between Iran and Oman through which roughly 20% of the world's oil passes. When Iran blockaded it in February 2026 during the conflict with the US, global oil supplies tightened dramatically, pushing prices up and inflation higher. A reopening would ease energy costs and allow the Fed to cut rates; continued closure keeps both elevated.
Cerebras Systems, a startup building custom AI chips, opened at $55 in its Nasdaq IPO Thursday and surged to a $95B market cap before closing Friday at $32.48, a 4% decline. The wild swing—from a 68% pop to a 4% loss in 24 hours—reflects profit-taking in a sector that has rallied relentlessly on AI infrastructure demand. The chipmaker competes with Nvidia and other AI accelerator makers, but its valuation (roughly $95B) is now being questioned by investors who worry that the AI chip space is becoming crowded and that custom silicon may not justify the premium multiples being assigned. The pullback is a warning sign for the broader semiconductor rally: Intel, AMD, and Micron all fell 3-5% Friday as investors rotated out of tech after the Trump-Xi summit disappointed. This suggests that while AI demand is real, the market may have gotten ahead of itself on valuations.
💡 A custom AI chip is a processor designed specifically for machine learning tasks (like training large language models), as opposed to general-purpose GPUs. Companies like Cerebras argue their chips are more efficient than Nvidia's, but they face the challenge of proving that efficiency gains justify the cost and complexity of switching from established platforms.
Cisco Systems jumped 13.4% Thursday after raising its fiscal 2026 revenue and earnings guidance, citing accelerating demand for networking equipment from enterprises deploying AI workloads. The company's strength signals that AI infrastructure spending is broadening beyond semiconductor makers to encompass switches, routers, and data center networking gear. Cisco's guidance raise is a bullish signal for the enterprise tech sector, suggesting that corporations are moving past the hype phase and actually deploying AI systems at scale. The stock's surge also reflects relief that enterprise IT spending remains resilient despite macro headwinds from the Iran conflict and inflation.
💡 Networking equipment includes switches and routers that connect servers and data centers. As enterprises build larger AI systems, they need more sophisticated networking to move massive amounts of data between GPUs and storage, making companies like Cisco beneficiaries of the AI buildout.
SpaceX is preparing to disclose its IPO prospectus as soon as next week, according to people familiar with the matter, after confidentially filing for a public offering in April. The company is expected to raise a record amount of capital, with a valuation likely exceeding $200B. The IPO would be one of the largest in US history and would give public investors exposure to Musk's space infrastructure business, which has benefited from government contracts and growing commercial satellite demand. The timing is notable given the broader tech selloff Friday—SpaceX's IPO will test whether institutional investors still have appetite for mega-cap tech offerings after the Trump-Xi summit disappointment.
💡 A confidential IPO filing allows companies to prepare for a public offering without immediately disclosing details to competitors. Once the prospectus is filed, the company's financials, business model, and risks become public, and the SEC reviews the filing before the company can begin roadshows to sell shares to institutional investors.
The CLARITY Act cleared the Senate Banking Committee on Thursday with a 15-9 vote, with two Democrats joining Republicans to push the bill forward. The legislation provides a regulatory framework for stablecoins (crypto-backed digital currencies), crypto derivatives, and custody arrangements, addressing years of regulatory ambiguity that has deterred institutional investors from entering the space. The bill's passage signals that Congress is moving toward clear rules rather than a patchwork of state-level regulations, which should unlock institutional capital flows into crypto. Bitcoin surged 1.98% Friday to $81,254 and Ethereum gained 1.2% to $3,247 on the news, as traders priced in the likelihood that regulatory clarity will accelerate institutional adoption. The CLARITY Act is expected to move to the full Senate floor in coming weeks.
💡 Stablecoins are cryptocurrencies designed to maintain a fixed value (usually $1) by being backed by reserves of dollars or other assets. The CLARITY Act would require stablecoin issuers to maintain 100% reserves and obtain federal charters, similar to banks. This removes the risk that stablecoins could collapse like FTX, which should encourage institutional use.
Solana spot ETFs attracted $39.2M in net inflows over the past week, marking the largest weekly inflow since February and signaling renewed institutional demand for the blockchain. Solana (SOL) is trading at $90.86, up 0.69% Friday, and is approaching the $120 resistance level as traders position for a potential breakout. The inflows reflect growing recognition that Solana excels at high-frequency trading, gaming, and SocialFi applications where low fees and fast settlement are critical. The CLARITY Act's passage is also boosting crypto sentiment broadly, as institutional investors see a clearer path to regulated crypto exposure. Solana's ecosystem has also benefited from the Firedancer validator client upgrade, which is expected to cut finality times to 150ms and improve network reliability—a key concern after multiple outages in 2022 damaged institutional confidence.
💡 Finality is the time it takes for a blockchain transaction to become irreversible. Solana's current finality is around 400ms; Firedancer will cut it to 150ms, making the network competitive with traditional financial systems for high-frequency trading applications.
Scientists studying octopus neurology have confirmed that these creatures possess not one brain but nine—a central brain in their head plus a mini-brain in each of their eight arms. Each arm-brain can process sensory information and execute motor commands independently, allowing an octopus to solve problems with one arm while another arm simultaneously hunts for food. This distributed intelligence system is so decentralized that if an arm is severed, it can continue to move and respond to stimuli for hours, operating as if it still has agency. The discovery has profound implications for how we think about consciousness and intelligence: octopuses don't experience the world as a unified self but as a collective of semi-autonomous agents. This radically alien form of cognition—so different from the centralized brains of mammals—suggests that intelligence itself is far more diverse and distributed than we've assumed. For investors and builders obsessed with AI, the octopus is a humbling reminder that biological intelligence solved the problem of distributed decision-making millions of years ago, and we're only now beginning to understand how.
💡 A mini-brain (or ganglion) is a cluster of neurons that can process information and control behavior locally, without waiting for signals from the central brain. In octopuses, each arm has roughly 2/3 of the neurons in the entire nervous system, giving each arm significant autonomy.
