Tech Powered the First Half. The Big Question Is Whether It Can Keep Going.

Technology roared back from a rocky start to become the best-performing sector of the second quarter, but a hawkish Fed and a concentrated rally are raising the stakes on whether AI leadership can hold β€” or whether the gains are ready to spread.

checked. 15:26 Tech Powered the First Half

As the second half of 2026 begins, investors are grappling with a market defined by one theme above all others: artificial intelligence. Technology stocks powered a remarkable first-half rally, and the central question now is whether that leadership can persist or whether the baton is ready to pass to other corners of the market.

A tale of two quarters

The first six months were a study in reversals. Tech stocks stumbled in the first quarter while energy names surged as fears of an Iran-driven oil shock rattled investors and threatened corporate profits. Those fears never fully materialized. As the conflict eased and crude tumbled from well above $100 a barrel to around $70, the trade flipped entirely. Technology became the top-performing sector of the second quarter, while energy slid and ended the half as the market's weakest group.

The engine: chips and the physical buildout

The rally's engine was the infrastructure powering AI. Semiconductor and memory-chip names posted staggering gains, with the sector's benchmark index climbing roughly 80% on the year. The optimism rests on a simple thesis: demand for AI computing is exploding, and the companies supplying the chips, servers, and equipment behind it stand to benefit for years. Whether that thesis holds through the next earnings cycle is the market's defining debate.

Some strategists argue the coming month will be decisive. Second-quarter results from chipmakers and the largest technology companies will show whether the blowout numbers that kicked off this reporting season can be sustained across the sector. If they can, the case for continued tech leadership strengthens. If they disappoint, a market that has concentrated its bets in a handful of names could prove vulnerable.

The case for broadening rather than breaking

But the smarter money may be on the rally widening rather than cracking. The AI boom isn't just a chip story anymore; it's an everything-that-powers-a-data-center story. Building and running these facilities requires enormous amounts of electricity, land, cooling, and heavy equipment β€” and that's begun lifting industrial and real-estate companies tied to the buildout.

Power has emerged as the clearest example. Bloom Energy and Brookfield announced Tuesday that they're expanding their AI infrastructure financing partnership fivefold, from $5 billion to $25 billion, to fund fuel-cell and onsite power systems for data centers that can't wait years for a grid connection. Bloom shares jumped more than 10% on the news. It's one of the clearest signs yet that the AI trade is spilling beyond Silicon Valley chipmakers and into the old economy β€” power generation, construction equipment, and industrial buildout.

More than just AI

There's also more to the second half than artificial intelligence. Financials, communication services, and healthcare all fell early in the year and rebounded strongly, and they remain reasonably valued against a stable economic backdrop. Even some consumer names trade at a discount to their historical averages. That breadth is what many strategists find encouraging: a market carried by a single theme is fragile, while one where multiple sectors participate is far more durable.

What to watch

  • Q2 earnings from megacap tech and chipmakers: The next several weeks of results will show whether the sector can sustain the growth rates that have justified its valuations.
  • The Fed's rate path: A hawkish Federal Reserve raises the cost of capital for the rich valuations AI stocks command β€” a headwind that grows more serious if rate-hike odds keep climbing.
  • Power-financing deal flow: Whether the Bloom Energy/Brookfield expansion is a one-off or the start of a broader wave of multibillion-dollar power deals tied to AI infrastructure.
  • Sector concentration risk: How much of the market's gains remain parked in a small handful of names, and whether breadth into financials, healthcare, and industrials continues to build.

The bottom line

Technology enters the second half as the clear leader, but its dominance is no longer unquestioned. The hawkish Fed raises the cost of the rich valuations AI stocks command, and the sheer concentration of gains in a few names is a risk in itself. The most likely path forward isn't a collapse of the AI trade but a widening of it, as the enormous investment required to build the AI era lifts a broader set of companies. For investors, the second half may be less about whether to own tech and more about what else to own alongside it.
