Samsung surges 10%, oil jumps 3% on Iran threats

On June 1, Samsung Electronics shares surged more than 10% to a record 349,000 won, pushing the common‑share market capitalization past 2,000 trillion won (about $1.5 trillion), the first Korean firm to cross that threshold. Analysts attribute the rally to strong AI‑chip demand and upbeat memory‑market outlook.

Iran's state‑affiliated Tasnim news agency announced Tehran has halted message exchanges with the United States and plans to fully block the Strait of Hormuz, threatening to disrupt a vital oil shipping lane. The move escalates tensions amid the ongoing three‑month Iran‑US conflict, with potential spikes in global energy prices.

Tom Tunguz notes that the combined $2.9 trillion market cap of SpaceX, OpenAI and Anthropic would require $432‑$576 billion of public float at typical 15‑20% levels, far exceeding the $469 billion raised by all US IPOs over the past decade. Consequently, the firms will likely float only 3‑8%, risking index‑fund strain and liquidity stress.

SpaceX’s planned $1.75 trillion IPO will likely be added to broad market indexes despite its lack of profitability, meaning retail investors in standard 401(k) funds could be compelled to hold the stock at peak prices. The move reflects recent rule changes that loosened index‑inclusion criteria, prompting concerns that passive portfolios may inherit extreme valuation risk.

Crude prices jumped more than 3% on Monday, with Brent topping $90 a barrel after US CENTCOM launched self‑defence strikes on Iranian sites. The surge erased gains made after recent diplomatic optimism and reflects renewed geopolitical risk around the Strait of Hormuz.

A U.S. jury convicted short‑seller Andrew Left, founder of Citron Research, of securities fraud, finding him guilty on a key count and 12 related charges while acquitting four others. Prosecutors said he manipulated markets through deceptive social‑media posts, potentially earning $20 million. Sentencing set for August 31.

The S&P 500’s record close was driven by just 20 stocks, chiefly AI and semiconductor firms, mirroring the narrow leadership at the 2000 dot‑com bubble peak. Strategists warn the limited breadth signals market fragility and suggest shifting to defensive assets.

Oil prices rose while spot gold slipped to about $4,500 per ounce after the United States launched self‑defence strikes on Iranian radar sites and Iran hit a U.S. base in Kuwait. The renewed fighting revived supply‑risk premiums and pushed inflation worries, keeping central‑bank policy on the tighter side.

Alphabet unveiled a plan to raise up to $80 billion through equity offerings, including a $10 billion anchor investment from Berkshire Hathaway, to fund massive expansion of its AI compute and infrastructure. The raise would be the largest equity sale in U.S. corporate history, underscoring the scale of the company’s AI capex push.

Elon Musk is weighing a merger of SpaceX and Tesla, which could combine the two companies into a $3.4 trillion conglomerate, though analysts say the deal would likely be loss‑making from day one. The discussion intensifies after SpaceX's amended S‑1 filing hinted at possible equity issuance that could fund a takeover.

Michael Burry warned that the Nvidia‑xAI financing scheme, backed by a $5.4 billion GPU sale to a shell company and debt sold to insurer Athene, could expose U.S. retirees’ annuity funds to AI‑related losses. He calls the structure “fugazi,” arguing the risk is hidden from corporate balance sheets but transferred to retirement investors.

Anthropic, the AI lab behind Claude, quietly submitted a draft registration statement on Form S‑1 to the SEC, enabling a future IPO if market conditions permit. The filing, made under Rule 135, does not set share count or price but marks a concrete step toward a potentially historic AI public offering.

Berkshire Hathaway announced a $6.8 billion cash purchase of homebuilder Taylor Morrison, its first major transaction led by new CEO Greg Abel. Shares slipped 1% as investors showed muted enthusiasm, but analysts note the deal fits Berkshire’s classic value‑focused, real‑estate play.

A Bain & Company survey of 951 large firms shows 40% recorded AI‑driven cost reductions of ten percent or less, far short of expectations. The modest returns arrive as Anthropic files for an IPO, underscoring doubts about enterprise AI’s payoff and the gap between hype and real‑world savings.

Jensen Huang told CNBC that the $660 billion AI infrastructure spend by major hyperscalers is justified and that all Nvidia GPUs, even older models, remain in high demand through rentals. His remarks aim to reassure investors that the AI boom’s capital spending is durable, countering growing doubts about overstated demand.

AWS announced a new "RNG" flat network topology using quasi‑random graphs and a ShuffleBox, replacing traditional fat‑tree designs. It reduces the number of routers by 69%, improves throughput by up to 33% and cuts network electricity use by about 40%, becoming the default for new AWS data centers.
