The S&P 500 paused on Wednesday after a blistering four-session rally of more than 5.5%, but the brief pullback has done little to dent growing conviction that U.S. equities still have room to climb.
Instead, the benchmark index’s march to successive record highs is reshaping expectations across Wall Street and prediction markets, with traders increasingly betting that the bull market has further to run.
Speculators on prediction market platform Kalshi now assign roughly a two-in-three probability that the S&P 500 will trade above the 8,000 level at some point in 2026. Based on Wednesday’s close, the benchmark is only about 3.6% away from reaching that milestone, revealing how quickly sentiment has shifted after a period of heightened geopolitical and macroeconomic uncertainty.

The contracts, which are settled using Google Finance data, allow traders to wager on whether the S&P 500 will exceed specific price thresholds during the calendar year. Beyond the 8,000 target, optimism is broadening. Kalshi traders now see roughly a one-in-three chance that the index could surpass 8,200 before the end of this year, reflecting growing confidence that the latest rally is more than a short-term rebound.
The renewed optimism comes after a volatile few months for U.S. equities. The S&P 500 rebounded sharply in April and May following steep declines triggered by the U.S.-Iran conflict, but momentum faded through late June and July as investors rotated out of the high-flying artificial intelligence stocks that had powered much of the market’s gains over the past year.
Rather than signaling the end of the AI-led bull market, however, that rotation has increasingly been viewed as a healthy broadening of market leadership. Investors shifted into financials, industrials, healthcare and other cyclical sectors, allowing the broader market to continue advancing even as several mega-cap technology stocks consolidated after outsized gains.
The latest four-day surge was driven by several powerful catalysts. Easing geopolitical tensions in the Middle East, particularly optimism that the Strait of Hormuz could reopen, helped push oil prices lower and reduced concerns over inflation and supply-chain disruptions. At the same time, another round of stronger-than-expected corporate earnings boosted confidence that U.S. companies continue to generate resilient profit growth despite elevated interest rates and ongoing global uncertainties.
Technology giants have remained central to that narrative. Strong quarterly results from companies including Amazon, Microsoft and other AI infrastructure leaders reassured investors that demand for cloud computing, data centers and artificial intelligence services remains robust. Those results also eased concerns that hyperscalers might begin scaling back their massive AI spending, a fear that had weighed on sentiment earlier in the summer.
Market participants also pointed to the near-collapse of Leopold Aschenbrenner’s Situational Awareness fund as another factor that accelerated the rally. The unwinding of highly concentrated positions appeared to remove a source of selling pressure from parts of the technology sector, allowing investors to re-enter AI-related stocks with greater confidence.
Importantly, analysts say the current advance is being supported by healthier market internals than earlier phases of the rally. Market breadth has improved as gains spread beyond the “Magnificent Seven” technology companies, reducing concerns that the market is being driven by only a handful of mega-cap stocks. Broader participation has historically been viewed as a positive signal for the durability of bull markets.
“Our investment thesis remains intact,” Truist Wealth Chief Market Strategist Keith Lerner wrote in a note on Tuesday. “Earnings remain our north star. Estimates continue to trend higher, economic growth remains resilient, and market participation has improved. Those are not conditions typically associated with the end of a bull market.”
The resilience of the U.S. economy has also supported the constructive outlook. While investors continue to monitor inflation and Federal Reserve policy, recent economic data have pointed to steady growth rather than a sharp slowdown, supporting expectations that corporate earnings can continue expanding. That backdrop has encouraged investors to look beyond short-term geopolitical risks and focus on the longer-term earnings trajectory.
