Markets just delivered one of the strongest weeks of the year.

The S&P 500 finished Friday at a record 7,757.64, rising 3.58% for the week. The Nasdaq jumped 5.19%, while the Dow gained 2.96%—the strongest weekly percentage advance for all three major indexes since April.

But the reason for the rally was unusual.

Corporate earnings were excellent. AI spending remained enormous. Oil fell sharply.

And then the U.S. economy unexpectedly lost jobs.

That combination dramatically changed what investors think the Federal Reserve will do next.

Here are the seven signals that mattered most.

1. The Jobs Report Changed the Fed Conversation

Friday delivered the week's biggest macro surprise.

The U.S. economy lost 23,000 jobs in July, compared with expectations for roughly 80,000 new jobs. May and June employment figures were also revised lower by a combined 103,000 jobs.

Even the decline in unemployment—from 4.2% to 4.1%—wasn't as reassuring as it first appeared. Around 264,000 people left the labour force, pushing participation down to 61.4%, near a five-and-a-half-year low.

Markets immediately repriced the Fed.

At the beginning of the week, futures implied roughly a 67% probability of a September rate hike. By Friday, that had fallen to around 44%.

That sent Treasury yields lower and technology stocks higher.

The signal: the market has moved from worrying primarily about an overheating economy toward questioning whether the labour market is starting to crack.

That is bullish for duration-sensitive stocks in the short run—but potentially less bullish if weaker employment develops into materially weaker consumer demand.

2. Wall Street Is Back at Record Highs

For now, investors are choosing the optimistic interpretation.

The S&P 500 gained 3.58%, the Nasdaq 5.19%, and the Dow 2.96% this week. Friday alone brought another 1.3% gain for the Nasdaq.

The rally wasn't based purely on rate expectations.

Corporate America continues to produce extraordinary earnings numbers.

Of the 436 S&P 500 companies that had reported by Friday morning, 85.1% beat analysts' earnings estimates, versus a long-run average of roughly 68%.

That matters.

For months, the bearish argument has been that valuations are too high and AI investment is too expensive.

Earnings are currently making that argument harder to sustain.

But valuation risk hasn't disappeared. It has simply moved further down the road.

3. Amazon Became a $3 Trillion Company

Amazon delivered one of the week's biggest milestones.

The company's market capitalisation crossed $3 trillion for the first time on Monday, with shares hitting a record after strong earnings revived confidence in AWS and AI infrastructure spending.

AWS recently delivered its strongest cloud growth in more than four years, while Amazon continues expanding relationships with AI companies including OpenAI, Anthropic and Meta.

Amazon shares were up more than 23% for 2026 as of Monday.

But there is a bigger message here.

Investors are no longer treating every mega-cap technology company as the same AI trade.

Companies capable of turning infrastructure spending into accelerating revenue are increasingly being rewarded.

Companies burning cash without demonstrating comparable returns are being questioned.

The AI trade is entering its execution phase.

Spending billions on GPUs is no longer enough.

Wall Street increasingly wants to see the revenue.

4. Palantir and Caterpillar Showed How Far the AI Boom Has Spread

One of the most important developments this week wasn't Nvidia.

It was Caterpillar.

Caterpillar climbed 5.6% Tuesday after increasing its revenue growth forecast, with management pointing partly to demand created by the construction of AI data centres.

Palantir was even more dramatic.

Shares surged 29.5% in a single session after the company raised its annual revenue forecast.

Meanwhile, the Philadelphia Semiconductor Index jumped 6.6% Tuesday, rebounding after losing more than 20% during July.

The message is worth remembering.

The AI investment cycle increasingly extends far beyond model developers and semiconductor companies.

It touches:

chips → servers → networking → cloud → power generation → cooling → construction → data centres → software

That wider infrastructure chain may become increasingly important as investors search for AI exposure outside the most expensive mega-cap names.

5. Not Every AI Earnings Beat Was Rewarded

There was also a warning this week.

AMD reported numbers above expectations and forecast strong demand for data-centre AI chips.

Investors still sold the stock.

AMD closed roughly 7% lower Wednesday, while several data-storage companies also declined despite beating revenue expectations.

SpaceX experienced something similar after releasing its first quarterly results as a public company.

Revenue jumped 92% year over year to $7.8 billion, comfortably above the $6.9 billion consensus forecast. The company also announced a data-centre chip partnership with Nvidia.

Yet SpaceX initially fell in after-hours trading as investors weighed AI expenditure, valuation and a major share unlock.

By Friday, however, sentiment had reversed: SpaceX was up roughly 19% for the week around midday.

The takeaway is simple:

AI growth is powerful, but expectations are now enormous.

A company can beat estimates and still disappoint the market.

6. Oil Had a Wild Week—and Hormuz Remains the Biggest Tail Risk

Oil went through another geopolitical roller coaster.

Brent finished Friday at $83.55 a barrel, but was still heading for a weekly decline of more than 8%, while WTI was down more than 7% for the week.

The reason was growing hope that an Iran-Oman arrangement could restore commercial shipping through the Strait of Hormuz.

By Friday evening, a U.S. official said Washington expected an agreement "soon" that could restore commercial traffic and lead the United States to lift its blockade of Iranian ports.

But this story is far from resolved.

Before the conflict, roughly one-fifth of global oil and LNG supply moved through Hormuz. Negotiations remain complicated by proposed transit fees, sanctions, insurance restrictions and disagreement over access for U.S.-linked vessels.

For equities, declining oil has been excellent news because it reduces one of the largest inflation risks facing the Fed.

A breakdown in Hormuz negotiations could reverse that quickly.

7. Gold Just Sent a Very Different Message

Stocks rallied.

But so did gold.

Gold jumped more than 7% this week, its strongest weekly performance in roughly seven months, reaching a seven-week high near $4,336 an ounce on Friday.

That combination is revealing.

Equity investors are buying stronger earnings and lower interest-rate expectations.

Gold investors are buying weaker employment, geopolitical uncertainty and the possibility that monetary policy becomes less restrictive.

Both trades can work simultaneously—but they reflect very different assessments of the underlying economy.

The Market Signal

This week strengthened the bullish case, but it also changed it.

The rally is no longer simply:

AI spending → technology stocks higher.

It is becoming:

Strong earnings + weaker jobs + lower oil → lower Fed pressure → higher equity valuations.

That setup can keep pushing stocks higher.

But it also makes next week's inflation data unusually important.

The S&P 500 is already up more than 13% in 2026, and investors have rapidly reduced expectations for a September Fed hike.

If inflation cooperates, the market could receive exactly what it wants: strong corporate earnings without another immediate tightening cycle.

If inflation remains stubbornly high, the Fed faces a much harder problem:

weakening employment and persistent inflation at the same time.

That would be a very different market.

What We're Watching Next Week

Wednesday — U.S. CPI: The biggest event. Consensus currently expects headline inflation around 3.4% year over year.

Fed expectations: Watch whether September hike probability remains below 50%.

Oil and Hormuz: Confirmation—or failure—of an Iran-Oman agreement could move energy, inflation expectations and equities simultaneously.

AI earnings: Applied Materials and Cisco are among the notable companies reporting.

Treasury yields: Falling yields helped power this week's technology rally. A CPI surprise could reverse that trade quickly.

Bottom line

The bulls won this week.

Earnings are strong, AI demand remains real, oil has fallen sharply, and the Fed suddenly has less room to tighten aggressively.

But Friday's employment report also gave investors their first serious warning that beneath record stock prices, parts of the real economy may be losing momentum.

The market is celebrating weaker jobs today.

The question for next week is whether inflation allows it to keep celebrating.
