Women’s representation on corporate boards across major U.S. companies slipped below a key threshold in early 2026, signaling a slowdown in recent gains at the highest levels of business leadership.
A new analysis by Women 50/50 found that women held 29.9% of board seats in companies within the Russell 3000 Index during Q1 2026. That marks a decline from the 30.4% peak recorded in the same period a year earlier.
The data suggests that most of the gains in women’s board representation continue to come from newly created board seats rather than replacement of existing male directors, according to CFO Dive.
About 86% of seats gained by women came from board expansions, while fewer than 14% resulted from direct turnover of male board members.
Slower Progress at Senior Levels
The findings show uneven progress for women in senior leadership roles. Prior industry studies have highlighted a persistent gap in promotion rates into management and executive positions, often referred to as a “broken rung” in corporate advancement pathways.
Other research has also found that women remain underrepresented in C-suite roles and are less likely than male peers to receive sponsorship, training opportunities, and leadership development support at similar career stages.
Diversity Trends Also Show Uneven Movement
The report also noted a slight decline in racial and ethnic diversity on corporate boards during the same period. Women of color held 7.3% of board seats in Q1, down marginally from the previous quarter, while men of color also saw a small decrease.
Representation varied significantly by sector. Utilities and consumer-facing industries recorded the highest share of women board members, while energy and financial services continued to lag behind.
Taken together, the data points to a plateau in board-level gender diversity after several years of gradual improvement, with recent gains becoming more dependent on structural expansion rather than replacement hiring within boards.
