2025 U.S. Private Equity M&A Activity Retrospective & 2026 Market Outlook

Breaking the trend of the last two (2) years, 2025 saw a historic return of sponsor-led deal activity culminating in an aggregate $1.2 trillion worth of transactions — the second-most all time — and an increase of 36.3% year-over-year against 2024. The surge in deal value was propelled by a continued wave of large and mega cap deals, which accounted for approximately $567.8 billion worth of sponsor-led deal activity across 150 transactions in 2025, as sponsors focused on fewer but larger transactions.

SCOTUS in Session: Tariffs, the “Shadow Docket,” and Executive Power

November 2025
SCOTUS in Session: Tariffs, the “Shadow Docket,” and Executive Power

The U.S. Supreme Court is back with a blockbuster docket that could reshape the balance of power, tackling issues from executive authority to the federal government’s role and the influence of lower courts. As the “shadow docket” grows and some judges voice concerns about the Court’s legitimacy, businesses are watching for a significant ruling on tariff-setting power that could affect the global economy.

On this episode of The Sidley Podcast, host Sam Gandhi speaks with Kwaku Akowuah and Tacy Flint to discuss these developments, the future of checks and balances, potential limits from Congress, and the Court’s major cases and increasing use of the emergency docket.
