A fresh analysis from global advisory firm Spencer Stuart reveals that diversity among S&P 500 corporate boards has slumped to its lowest point in over ten years, reflecting the impact of a conservative legal and political assault on diversity, equity, and inclusion (DEI) programs.
The study, released Tuesday, found that diverse board appointments peaked at 72% in 2021 but have been declining ever since. Today, diverse directors occupy 49.3% of board seats, a slight dip from the record 49.6% seen in 2024. The report also notes that the number of new directors entering boardrooms is at its lowest since 2026.
George Anderson of Spencer Stuart told Reuters that corporate boards are recalibrating their priorities in response to shifting legal, regulatory, and political pressures. The 2023 Supreme Court decision banning race-conscious college admissions, combined with sustained attacks from the Trump administration on DEI initiatives, has prompted many companies to scale back or abandon such programs.
A White House fact sheet from March labeled DEI initiatives as “racially discriminatory” and claimed they impose “real costs on the American people.” President Trump’s executive order went further, declaring DEI efforts “illegal” and arguing they “not only violate the text and spirit of our longstanding Federal civil-rights laws, they also undermine our national unity” and “American values.”
Major corporations, including Meta, Google, and several Wall Street banks, have walked away from DEI commitments in the wake of these attacks. However, not all firms have followed suit. Costco, for instance, rejected a shareholder proposal from the National Center for Public Policy Research demanding a report on the risks of maintaining its DEI policies. The company told investors that such efforts “enhance our capacity to attract and retain employees who will help our business succeed,” urging a vote against the measure.
The retreat from diversity comes amid a broader conservative push to reshape corporate governance. The political climate has also influenced recent mid-decade redistricting efforts that have yielded a House map nearly as favorable to Republicans as 2018's. Meanwhile, the administration's focus on rolling back progressive policies has extended beyond corporate boardrooms, with aid cuts in 2025 threatening decades of HIV progress, according to recent reports.
The Spencer Stuart analysis is based on data collected from May 1, 2025, to April 30, 2026, drawing on the latest proxy statements from 488 companies. The findings underscore a sharp reversal from the diversity gains of the early 2020s, raising questions about the long-term trajectory of corporate inclusion in an increasingly polarized political environment.
As the debate over DEI continues, the decline in boardroom diversity highlights the broader generational chasm in American politics, where younger voters often prioritize inclusion while older demographics and conservative leaders push back. For now, corporate America appears to be bowing to political headwinds, but the fight over representation in the boardroom is far from over.
