Micron's Record Profits Signal AI Boom is Accelerating

The AI Chip Sector: A More Crowded Throne

Just as doubts began to creep in about the sustainability of AI spending, memory chipmaker Micron delivered a historic quarterly report that silenced the sceptics. The results have provided a significant boost to the entire semiconductor industry, but a closer look reveals a landscape where competition is heating up, and the costs of the AI buildout are coming under intense scrutiny.

Unprecedented Profitability

Micron's performance was extraordinary, with revenue soaring to $41.5 billion, a staggering 346% increase from the previous year and far exceeding analysts' expectations. The stock, having already run up over 700% in the last 12 months, is now poised to open at a new all-time high. The company's gross margin – a key measure of profitability – reached a record 84.9%. To put this into perspective, Micron's margin now surpasses those of tech giants like Meta (81.9%) and even the AI darling Nvidia (75%), crowning it as Wall Street's new king of profitability.

The company's forecast was equally strong, guiding for current-quarter revenue of around $50 billion, well above what experts had predicted. With $18 billion in free cash flow generated in the quarter, Micron is using its market power to lock customers into five-year supply agreements to secure its position.

The High-Bandwidth Memory Bottleneck

The driving force behind these numbers is the insatiable demand for High-Bandwidth Memory (HBM). These are the specialised, stacked chips that act as the fuel for powerful AI processors. According to Micron's chief executive, demand is so strong that its HBM is completely sold out, with the shortage now expected to persist beyond 2027. This scarcity has created a "Micron tax" for tech firms, shifting the bottleneck in the AI supply chain from the processors themselves to the memory that feeds them.

Competition Heats Up

However, Nvidia's recent stock performance serves as a cautionary tale. Being on top makes you a target. A flood of new AI processors is disrupting what was once a near-monopoly, and the same competitive pressures are now building in the memory sector.

• Custom Chips: OpenAI, the developer of ChatGPT, has partnered with Broadcom to unveil its first custom AI chip, codenamed "Jalapeño," aimed at reducing its reliance on Nvidia.
• New Alliances: Chip designer Qualcomm revealed that Meta will use its next-generation CPUs from 2028, and Microsoft will use its new High Bandwidth Compute chips. Underlining its ambition to diversify beyond smartphones, Qualcomm has nearly doubled its 2029 revenue target for non-handset sales to $40 billion.
• SK Hynix Listing: Capitalising on the frenzy, South Korean rival SK Hynix is set to list on the Nasdaq on July 10th. The company, a primary HBM supplier to Nvidia, aims to raise up to $29.4 billion in what could be one of the largest US listings in history. This will grant US investors direct access to another key player in the AI memory boom.

The Soaring Cost of AI

The AI party's bill is coming due. The biggest technology firms shed a collective $2.7 trillion in market value in June as investors shifted from pricing in AI's promise to pricing in its immense cost. The biggest expense is electricity. This has sparked a race for energy independence, with Amazon investing in nuclear power and Google acquiring renewable energy developers to power their data centres more cheaply.

Defence Sector: A Tale of Two Tiers

Modern conflicts in Ukraine and the Middle East have exposed the limits of traditional, expensive military hardware. The battlefield is now increasingly dominated by low-cost, effective drones, a shift that is triggering a massive overhaul of defence spending in Washington and creating a clear split in the sector's fortunes.

The Rise of the Drone Economy

This trend, known as asymmetric warfare, is where cheaper weapons can neutralise far more expensive systems. In response, the Pentagon's budget for its Defense Autonomous Warfare Group (DAWG) is projected to explode from $225 million in 2026 to an incredible $55 billion in 2027. Some analysts estimate the US market for cheaper drones could approach $100 billion annually.

This has created a new class of winners in the defence industry. Companies gaining direct battlefield experience, which analysts call the industry's "seal of approval," are in the spotlight. Key names in this emerging sector include:

• AeroVironment (AVAV): A proven supplier of reconnaissance and "loitering munition" drones used in Ukraine.
• Kratos Defense (KTOS): A developer of advanced combat drones like the XQ-58A Valkyrie.
• L3Harris Technologies (LHX): A major defence contractor with significant exposure to the drone supply chain.

Headwinds for Traditional Giants

In stark contrast, large-cap US defence firms like Lockheed Martin and Northrop Grumman have seen their stock prices sink recently, partly due to the conclusion of the US-Iran conflict. Meanwhile, in Europe, Germany scrapped a major $14.5 billion warship order, its largest since WWII, causing shares in contractor Rheinmetall to dip. The move signals a shift towards smaller, more agile vessels, reflecting the same strategic pivot seen with drones.

US Market & Economic Movers

Away from the tech and defence spotlight, several other key developments are shaping investor sentiment in the United States.

Oil and Petrol Prices Diverge

Crude oil prices have fallen sharply, with the US benchmark dropping below $70 a barrel and Brent crude trading around $72.75. The drop was triggered by the reopening of the Strait of Hormuz, a critical shipping lane, which has released more supply onto the market. The US Energy Secretary has since stated that Iran would no longer be able to close the strait, citing US military escorts for commercial ships. While lower oil prices are good news for easing inflation and have sent airline stocks soaring on lower fuel costs, petrol prices at the pump have not fallen as quickly. This has prompted President Trump to order the Department of Justice to investigate whether oil companies are artificially keeping prices high for consumers.

US Banks Sail Through Stress Tests

The 32 largest US banks have passed the Federal Reserve's annual stress tests, confirming they have enough capital to withstand a severe recession, including absorbing over $700 billion in loan losses. The positive results have prompted a wave of capital returns to shareholders. JPMorgan, Wells Fargo, Goldman Sachs, and Morgan Stanley have all announced plans to increase their dividends and buy back shares.

Homebuilders Face Political Stalemate

Homebuilder stocks rallied after Congress passed legislation aimed at boosting housing supply. However, the bill's future has been thrown into doubt and now sits in limbo. President Trump abruptly cancelled the signing ceremony, posting on social media that he would not approve the housing reforms until Congress first passed the controversial SAVE America Act, a separate voter identification bill. This political wrangling injects uncertainty into a sector already grappling with high mortgage rates.

Commercial Real Estate Shows Cracks

Concerns are mounting over the health of the commercial property market after a prominent office tower in Chicago defaulted on its $343 million bank loan. The building, One South Wacker, is 73% occupied and was recently renovated, making the default particularly worrying. If a relatively healthy building cannot refinance its debt in a city with 27% office vacancy, it raises serious questions about the stability of weaker properties across the country.

Copper's Rally Hits a Wall

The recent rally in copper has lost steam, with prices sliding. A strong US dollar is making the metal more expensive for international buyers, while the Federal Reserve's commitment to keeping interest rates high makes holding non-yielding commodities less attractive. Adding to the pressure, global copper supply is reportedly at its highest level since 2003.

Auto Sector Shake-Up: Toyota Gains on GM

A significant shift is underway in the US car market, where Toyota is closing the sales gap with rival General Motors. New forecasts show Toyota's sales are expected to climb by nearly 1% in the first half of the year, while GM's are projected to drop by over 7%. The change is largely down to strategy; Toyota's long-standing leadership in hybrid vehicles is paying off as consumer demand for them grows. In contrast, GM's heavier focus on all-electric vehicles is facing a tougher market, creating a potentially worrying trend for the American auto giant.

Meme Stock Frenzy Returns with Wendy's

The volatile 'meme stock' phenomenon appears to be back, with fast-food chain Wendy's becoming the latest target of retail investors. The company's shares soared by 25% in a single day, driven by a surge of mentions on Reddit's popular trading forums. The influx of cash from everyday investors was far beyond typical levels, echoing the short squeezes seen during the 2021 market craze. With the stock climbing even higher in pre-market trading, it signals that this retail-driven momentum may not have finished yet.

Alphabet Officially Joins the Dow Jones

Google's parent company Alphabet officially replaced Verizon in the Dow Jones Industrial Average on June 29th. Because the Dow is weighted by share price, Alphabet's high price gives it a roughly 5% influence on the index. This change pushes the 130-year-old index's exposure to mega-cap technology firms to a record high.

Global Market Spotlight

SoftBank Bets on AI Data Centres via Tepco

Japanese investment giant SoftBank is seeking to buy a stake in Tepco, Japan's largest electricity provider. The move is a strategic play on AI, as Tepco is building out a network of AI data centres. The deal provides Tepco with much-needed cash as it continues to pay for the cleanup of the Fukushima nuclear disaster, while giving SoftBank direct exposure to the AI infrastructure boom in Japan.

India's Tech Sector Loses Its Sheen

The recent wobble in technology stocks is a global phenomenon. In India, the tech sector's weighting in the Nifty 50 index has fallen below 7.6%, its smallest share in over two decades. The Nifty IT index has dropped 29% this year as investors grow concerned that AI may not generate the same kind of economic growth that traditional IT services once did for the country.

Alibaba's Legal and Reputational Headaches

Chinese tech giant Alibaba is facing pressure on multiple fronts. The company is suing the US Department of Defense to be removed from a blacklist of alleged "Chinese military companies." Separately, AI firm Anthropic has accused Alibaba of attempting to illicitly copy its AI models. These events keep the US-China tech rivalry in the spotlight, acting as a persistent drag on Chinese equities.

Cryptocurrency Crosswinds

Beyond Bitcoin's price movements, several significant developments are shaping the broader digital asset landscape, from internal restructuring at key organisations to ongoing security challenges and new avenues for investment.

Bitcoin Tests Key Support Levels

Bitcoin's decline has seen it test the critical $60,000 mark several times, its lowest point since October 2024. Its performance has become increasingly tied to big technology stocks, with a sell-off in AI equities dragging crypto lower. This confirms that many large investors treat it as a high-risk tech asset rather than an independent inflation hedge. Worries over potential interest rate hikes also continue to weigh on assets that don't provide a yield. The key price level to watch remains the $59,000 to $60,000 range, which many analysts see as a critical support floor for the cryptocurrency.

Hong Kong Crypto ETFs Attract Capital

In a sign of growing mainstream adoption in Asia, Hong Kong's crypto Exchange-Traded Funds (ETFs) have nearly doubled their assets under management to around $550 million since launching last year. With trading volumes on the city's licensed platforms jumping 125%, regulators are now working on four new rulebooks to better govern the rapidly expanding market.

Ethereum Foundation Realigns

In a significant move, the Ethereum Foundation has reduced its workforce by about 20%, letting go of 54 staff members. The Swiss-based non-profit, which supports the Ethereum network's development, described this as the final step in a months-long reorganisation. The leadership believes the leaner team is now better structured for its key tasks.

Major Investor Boosts ETH Holdings

Despite market jitters, some large players are increasing their bets on crypto. Bitmine Immersion Technologies recently purchased another 52,203 Ether (ETH), lifting its total holdings to 4.7% of the entire ETH supply. The firm, now the largest corporate holder of ETH, is actively staking most of its $9.8 billion position to earn revenue.

Bridge Exploit Rocks Taiko Network

The risks inherent in the crypto space were highlighted when the Taiko network, an Ethereum Layer 2 solution, was forced to halt its operations following a hack. An attacker drained approximately $1.7 million after discovering a security key that was mistakenly exposed online. The incident, which caused the network's TAIKO token to fall by over 20%, is the latest in a string of "bridge" exploits—attacks on the links between different blockchains.
