More Keys for Markets in 2026: LPL Market Outlook Sneak Peek

In our Weekly Market Commentary on November 17, we previewed our Outlook 2026 publication, due out on December 9. We highlighted several keys for markets next year, covering the U.S. economy, stocks, and bonds. This week, we broaden our preview and tease some other factors investors will want to consider when thinking about investing in 2026.

Quick Recap

First, here’s a summary of the keys to 2026 that we covered in our previous Outlook 2026 teaser on the U.S. economy, stocks, and bonds:

  • No recession. In the absence of an economic contraction, stocks have historically delivered gains. LPL Research does not expect recession in 2026, providing a supportive backdrop for equities.
  • Fiscal stimulus. The One Big Beautiful Bill Act (OBBBA) is expected to support economic growth, revenue, and profits for corporate America.
  • Solid earnings. The ongoing string of double-digit earnings growth is poised to continue. Strong earnings, bolstered by technology innovation, will be critical in supporting elevated valuations with the price-to-earnings ratio (P/E) for the S&P 500 over 22 times 2026 consensus earnings per share (EPS) estimates.
  • Artificial intelligence investment and adoption. The primary artificial intelligence (AI) hyperscalers — Alphabet (GOOG/L), Amazon (AMZN), Meta (META), Microsoft (MSFT), and Oracle (ORCL) — are projected to spend $520 billion to build out AI infrastructure in 2026, potentially 30% above 2025 levels. That investment will need to fuel productivity gains for corporate America and support higher profit margins.
  • Supportive monetary policy. Federal Reserve (Fed) rate cuts aimed at normalizing policy, rather than staving off recession, would likely support further gains for stocks in 2026. If those cuts are accompanied by further progress in tamping down inflation, 2026 could be a good year for bonds as well as stocks.
  • Manageable deficit spending. If tariff revenue comes through and helps offset most, if not all, of the additional deficit spending on tap for 2026, then the yield impact of additional Treasury supply may be manageable. Stable Treasury yields should be good for stocks and bonds.
  • Stable credit markets. Despite rising idiosyncratic risks in credit markets recently, credit spreads remain tight. Healthy credit markets that help preserve those tight spreads will be key to bond market performance in 2026.

More Keys To 2026: Teaser Style

As we put the finishing touches on Outlook 2026, here are several other key factors that will drive markets in 2026 that investors will want to keep in mind.

Midterm Elections

Midterm elections in 2026 could reshape Washington and markets. All 435 House seats and one-third of the Senate are up for grabs, with Republicans holding razor-thin majorities. Historical trends suggest the president’s party often loses ground, raising the risk of a power shift. For investors, midterm years have historically been volatile, with the S&P 500 averaging a 17.5% drawdown before a typical strong rebound post-election. How markets handle this political uncertainty will be key in 2026.

Resurgent Corporate Dealmaking

Merger and acquisition (M&A) activity is gaining traction after a muted period, driven by deregulation, Fed rate cuts, and surging demand for AI-related transactions. With deal volume trending higher, as illustrated in the “M&A Activity is Gaining Momentum” chart, it creates attractive opportunities for merger arbitrage strategies and private equity investors in the alternative investments arena. The backdrop suggests improving conditions for dealmakers, which could broaden the investible universe, and support returns in 2026.
