Wall Street’s run: The day tech titans wrote history

From the moment New York stirred awake, Monday set itself up as a day Wall Street would remember. Across the trading floor, monitors blinked into record territory. Tech giants, led by Nvidia, Apple and Tesla, became the heartbeat that pushed American indices higher once more. But this was no mindless rally, every tick upward told a story about the future, uncertainty, and the powerful role of innovation.

A tale of two powers: Nvidia and the Federal Reserve

The headline that got everyone’s attention: Nvidia’s plan to invest a jaw-dropping $100 billion in OpenAI. It wasn’t just a press release; it was a scene-stealer. As Nvidia’s stock soared nearly 4%, CEO Jensen Huang told CNBC, “This project with OpenAI is equivalent to between four and five million GPUs”, a reminder of just how much hardware is fuelling tomorrow’s technology.

OpenAI’s CEO Sam Altman put it even more simply: “Compute will be the foundation of the economy in the future… With Nvidia, we will achieve new AI advancements and empower individuals and businesses at scale”. For many traders, this sounded like the beginning of a new industrial revolution. As Halter, a tech analyst, explained, “Nvidia’s investment signals that the need for AI infrastructure is real and still expanding”. One could almost smell the optimism on the trading floor as Oracle enjoyed a 6% rally on the day, and Apple shot up over 4%, buoyed by better-than-expected iPhone 17 sales.

But while mega-cap tech played market hero, eyes were never far from the Federal Reserve. Last week’s quarter-point rate cut was still rippling through investor sentiment. As Ed Harrold, investment director at Capital Group, reflected: “Today’s rate cut in the face of a softening economic picture is a sign the Fed is willing to support the economy despite potentially stubborn inflation”. It summed up the paradox everyone was feeling, markets climbing on innovation, while the central bank sent out careful signals about economic cracks beneath the surface.

The rally’s tension: Hope, caution, and what comes next

With all three major indices closing at all-time highs, September’s notorious reputation for weak performance was nowhere to be seen. “The S&P 500 is now up 13.8% for the year so far and up 3.6% for September, a month that is historically weak for stocks,” Reuters noted, highlighting just how extraordinary this run has been.

But not everyone was bullish. Lindsay James, investment strategist at Quilter, remarked, “Until sharp data revisions… prompted Powell to highlight a ‘shifting balance of risks’, this [Fed] cut was seen as hanging in the balance. The decline in job creation… has highlighted that cracks are emerging in the US economy and the Fed clearly feels it warrants action”.

Gold’s rally to record highs, even as tech shares conquered new ground, told its own story of a market hedging its bets, a classic dance of risk versus reward. As investors turned to Tuesday, one thing became clear: the plot now hangs on the next round of inflation data, and whatever the Fed does next.

Story after story, the real headlines are not just about points on a graph or percentage gains. They’re set by the bravado of companies like Nvidia, the caution of the Fed, and the constant pulse of optimism and doubt that makes Wall Street the stage for stories that affect us all.
