South Korea's KOSPI plunged 10.8% and triggered a circuit breaker after China's CXMT surged in its market debut. Brent fell below $88 as the U.S.-Iran pause entered a third day. Bitcoin traded near $63,173. The Fed begins its two-day meeting today.

MARKET PULSE

The AI trade found a new pressure point.

South Korea's KOSPI plunged 10.84% Tuesday and triggered a market-wide circuit breaker, its eighth halt this year.

Samsung Electronics fell 13.4%.

SK Hynix lost 14%.

Japan's Nikkei dropped nearly 4%, while Kioxia fell 18%.

The catalyst was larger than one company.

Chinese memory chipmaker CXMT surged as much as 530% after listing in Shanghai, reaching a market value near $500 billion. The company now holds about 7.6% of the global DRAM market, nearly double its share from one quarter ago.

The move landed just days after Alphabet (GOOGL) shook investors by raising 2026 capital spending guidance to $195 billion to $205 billion. Revenue rose to $119.8 billion. Google Cloud grew 82%. Quarterly capex reached $44.9 billion, up 101% from a year ago, while free cash flow turned negative.

U.S. futures were mixed.

S&P 500 futures slipped 0.1%. Nasdaq 100 futures fell 0.5%. Dow futures added about 30 points. The 10-year Treasury yield remained near 4.7%.

Brent traded below $88.

Bitcoin changed hands near $63,173.

The calendar stays crowded.

Case-Shiller home prices and consumer confidence arrive today.

The Fed announces its decision Wednesday.

Microsoft (MSFT) and Meta (META) report Wednesday evening.

GDP and jobless claims arrive Thursday morning.

Apple (AAPL) and Amazon (AMZN) report Thursday evening.

PCE inflation closes the week Friday.

The Signal

The KOSPI circuit breaker captured the market's biggest concern. AI spending keeps rising while competition and returns become harder to predict.

ENERGY

Oil continued falling.

Brent dropped to $87.24. WTI traded near $81.60.

The decline followed Monday's 8.7% plunge in Brent as the U.S. and Iran kept their pause in fighting for a third day.

President Trump said talks with Iran were progressing. Iranian and Omani officials continued discussions on restoring shipping through the Strait of Hormuz.

Iran has paused retaliatory attacks after Washington suspended nearly two weeks of bombing.

The market welcomed the pause.

The shipping market did not.

Hormuz remains effectively closed to normal tanker traffic.

Loadings inside the Gulf remain well below pre-war levels.

Insurers and shipping companies have not restored normal routes.

Lower oil helps inflation.

It does not solve the supply problem.

Energy Signal

The panic faded. The physical disruption remains.

MACRO

The Fed begins its two-day meeting today.

The decision comes Wednesday afternoon.

Markets assign about a 35% chance of a rate hike this week.

September remains the larger risk, with markets pricing roughly an 80% chance of higher rates.

The current target range is 3.50% to 3.75%.

This meeting does not include updated projections or a dot plot.

That puts the focus on Chair Kevin Warsh's statement and press conference.

Oil is helping the Fed.

Brent has fallen more than $14 from last week's peak.

June payrolls increased only 57,000.

Those numbers support a hold.

The risks have not disappeared.

Federal debt reached a record $39.7 trillion last week and continues growing by roughly $7 billion per day.

Core inflation remains above target.

Markets want a steady message.

Any hawkish surprise could push bond yields even higher.

Macro Signal

The decision matters. Warsh's words matter more.

Louis: The "Strawberry Problem" Is Stalling the AI Revolution

Billion-dollar tech investor Louis Navellier calls it "AI's darkest secret." Until AI models solve the "Strawberry Problem," they'll never create new breakthroughs in medicine, energy, or quantum computing. The good news? One company is about to solve the crisis… unleashing a new $100 trillion opportunity.

Alphabet changed the earnings playbook.

Now Microsoft and Meta must answer it.

About 82% of S&P 500 companies have beaten earnings expectations this season.

Investors still punished Alphabet after management raised AI spending without showing when returns will arrive.

Microsoft is expected to spend about $118.9 billion next fiscal year, up 22%.

Meta's projected capex reaches $135.2 billion, up 79%.

Both report Wednesday after the Fed.

Investors want proof that spending is creating demand rather than simply building infrastructure.

China added another challenge.

Apple is reportedly testing CXMT memory chips for devices sold in China.

That increases pressure on Samsung, SK Hynix, and Micron (MU).

Thursday shifts the focus to crypto.

Coinbase (COIN) reports after the close.

Analysts expect revenue to fall 11.4% to $1.33 billion.

Strategy (MSTR) also reports Thursday after holding 843,775 Bitcoin while rebuilding cash reserves. Its mNAV has recovered to about 1.03 after briefly falling below parity.

Capital Signal

This week decides whether AI spending is becoming a competitive advantage or simply a larger expense.

CRYPTO PULSE

Bitcoin traded near $63,173.

Ethereum slipped to about $1,880.

XRP fell 4.55%.

Solana lost 4.23%.

Today's crypto story is split between technology and macro.

Zcash activates its Ironwood upgrade today.

The update closes the older Orchard shielded pool, moves users into a stronger system, and checks the network's supply after a bug discovered earlier this year.

A successful launch removes a major question around Zcash.

The Fed remains the larger catalyst. A hold with softer language supports Bitcoin. A hawkish message could pressure crypto again.

Spot Bitcoin ETFs added $33.8 million during the week ended July 24, marking a third straight week of inflows.

Even so, funds remain about $4.84 billion lower for the year.

Another event arrives Wednesday.

Hyperliquid unlocks about $817 million of HYPE tokens.

FTX begins another creditor distribution Friday worth about $900 million.

The Senate still has not scheduled a vote on the CLARITY Act before the August recess.

The Verdict

Crypto enters the Fed meeting with improving ETF demand but several major catalysts still ahead.

Buffett, Gates and Bezos Quietly Dumping Stocks—Here's Why

The world's wealthiest individuals are making huge moves with their money.

Warren Buffett just liquidated billions of shares. Bill Gates sold 500,000 shares of Microsoft. Jeff Bezos filed to sell Amazon shares worth $4.8 billion.

What is going on? One multi-millionaire believes they are preparing for a catastrophic event. But not a crash, bank run, or recession. It’s something we haven’t seen in America for more than a century.

CLOSING LENS

Tuesday begins with one message.

The market wants proof.

South Korea's circuit breaker showed how quickly confidence can disappear when AI competition changes.

Oil below $88 gives the Fed more room.

It does not reopen Hormuz.

Wednesday brings the Fed.

Hours later, Microsoft and Meta report.

Thursday follows with Apple and Amazon.

Bitcoin is watching the same events.

If the Fed holds and hyperscalers prove AI spending is producing returns, the market gets a new reason to buy.

If not, last week's repricing becomes this week's trend.
