Following a first half marked by geopolitical conflict, extreme oil price volatility, and significant swings in interest rate expectations, Wall Street is approaching the second half of 2026 with a rare and consistent optimism—the prevailing view being that the market has demonstrated its resilience and will continue its upward trajectory.
A diversified portfolio comprising U.S. stocks, U.S. Treasuries, and commodities has just recorded its strongest first-half returns since 2021. Semiconductor stocks have seen triple-digit gains, the Nasdaq 100 Index has risen nearly 20%, and U.S. Treasuries have also delivered positive returns. In the mid-year outlooks from nearly all major institutions, Wall Street is betting that the market can coexist with higher valuations, elevated borrowing costs, and the ongoing, landscape-altering wave of artificial intelligence.
However, the good news may already be largely priced in. Strategist forecasts compiled by Bloomberg show a year-end average target for the S&P 500 of 7,716 points, implying an upside of only about 3% from its closing level on June 30, while the index has already gained roughly 9% this year. The divergence in focus is not on the direction but on whether leadership can broaden from the core AI trade to a wider range of sectors.
The First Half: Resilience Exceeding Expectations
Market performance in the first half exceeded most expectations despite multiple shocks.
"The global economy and financial markets have performed better than many anticipated," wrote Stephen Dover and Larry Hatheway of the Franklin Templeton Institute. "The central theme of the outlook coalesces into one word: resilience."
Yet, the winners of the first half were somewhat unexpected. The 'Magnificent Seven' cohort, which defined the market over the past two years, saw its total return fall by about 2%, even underperforming UK government bonds, as investors shifted funds from the tech giants deploying AI to the companies building AI infrastructure. Gold, silver, and Bitcoin all ended the first half lower despite months of geopolitical turmoil.
Barclays noted that this rally has been far more concentrated than the index performance suggests—semiconductor and computer hardware companies accounted for roughly 87% of the S&P 500's first-half gains.
AI Trade Diffusion: From Tech Giants to the Real Economy
Heading into the second half, Wall Street's core narrative is subtly shifting: the beneficiaries of the AI trade are spreading from hyperscale tech companies to the real economy.
Institutions like BlackRock and Invesco believe AI investment is accelerating its penetration into areas such as semiconductors, memory, power grids, data centers, and industrial infrastructure. A team led by Jean Boivin at the BlackRock Investment Institute wrote, "We prefer to harvest yield in short-dated bonds, particularly euro area government bonds, rather than rely on longer-duration bonds that are more sensitive to interest rate volatility. We maintain an overweight to U.S. equities, focusing on bottleneck opportunities in AI growth."
JPMorgan, meanwhile, anticipates a rebound in inventories, improved business confidence, and an expansion of AI spending beyond the hyperscale tech companies.
"Record earnings growth and AI-driven enthusiasm have propelled risk assets to new highs," said Raphael Thuin, Head of Capital Market Strategy at Tikehau Capital in Paris. "But the second half is unlikely to be a simple repeat of the first. Parts of the AI 'picks and shovels' trade appear overstretched, and any shift in the narrative around computing power demand could rapidly reshape market leadership."
Risks Remain: Inflation, Policy, and Geopolitics
Beneath the optimistic consensus, risks have not dissipated, with differences among parties more about degree than direction.
The new quarter began with a reminder: June's non-farm payrolls data showed a clear cooling in hiring, but the unemployment rate fell due to a drop in labor force participation, prompting traders to dial back expectations for Federal Reserve rate hikes.
JPMorgan warned that if economic resilience persists, inflation could remain sticky, forcing central banks to tighten policy further. "I have every reason to believe that the second half of 2026 will be as eventful as the first," wrote Barclays strategist Alexander Altmann. "The past six months have already seen three major geopolitical conflicts, the second-largest semiconductor rally in history, and the sixth-largest software stock sell-off on record."
"AI has proven to be a stabilizing force for a world simultaneously facing geopolitical and monetary policy uncertainty," noted Marvin Loh, Senior Macro Strategist at State Street in Boston. "But while AI construction appears to have unlimited liquidity, the reality is different, and this will test the availability and cost of capital in the second half."
The common thread running through almost all outlooks is that the economic expansion continues. The bigger debate is not whether the first-half story continues, but whether market leadership can broaden beyond the AI trade itself, or if the next set of winners will simply be a different batch of AI beneficiaries.
