What the Latest Research Is Telling Us About Co-Leadership in 2026
Leadership has never been a solo sport — even when we have treated it that way.
For decades, the dominant image of a leader was one person at the top: the CEO, the executive director, the principal. One person accountable. That model is being quietly, persistently dismantled by practitioners, researchers, and organizations who have discovered that sharing leadership is not a compromise. It can be the smarter choice.
The research is catching up to what many of us already know
For years, shared leadership research asked a basic question: does it work? The answer is yes. Teams that distribute leadership outperform those with a single designated leader, show stronger cohesion, and demonstrate greater adaptability.
Also, the answer is no. Too many prominent business CEO breakups reduce public trust; made worse by some research studies, such as one 2017 study reported in the Academy of Management finding high power individuals are prone to power struggles and cognitive paranoia when called to work together, damaging outcomes.
Researchers are no longer just asking whether shared leadership works — they are asking how and why.
A 2024 study published in Group & Organization Management followed 85 teams through a decision-making task and found that teams that shared leadership performed better and learned faster. The mechanism that explains why turns out to be collective efficacy — the shared belief that the team can succeed together. This has implications for how we design teams, onboard leaders, and build organizational culture to create places where leaders believe they can succeed together. Without intentional cultural shifts, co-leadership can be just a structural arrangement with all the trappings of hero leadership.
Co-leadership has growing appeal, and may indeed be The Future of Leadership. It can address the flexibility that sole leadership does not. For example, shared leadership de-stresses maternity and paternity leave, and time off for family emergencies, because while one leader is out of office the other leader is still at work. In January 2026, the BBC’s Why are more bosses sharing the top job offered profiles of a few companies making co-leadership work, adding that the number of public companies with co-CEOs had more than doubled from 2015 to 2024.
Evolving beyond just efficiency and productivity, equity intentions lean toward liberation
Meaningful developments of the past few years come from the nonprofit sector. Opposite university laboratory research under controlled conditions, nonprofits have produced studies yielding rich best practices, using real co-leaders in the wild.
Mosaics & Mirrors, published by co-leaders Devi Leiper O’Malley and Ruby Johnson, included investigation of 25 co-leaders and practitioners, and offers one of the few detailed guidebooks for each stage of the co-leader journey. The feminist co-leaders believe co-leadership can offer a pathway toward collective liberation. Mosaics stands as an example of activism as practice.
In February 2026, researchers at Drexel University's Dornsife School of Public Health published a detailed account of their Shared Leadership Team — a body of students, faculty, and staff across units created to guide DEIB initiatives for addressing racism and discrimination as a health priority. Their core insight: traditional hierarchical decision-making structures can replicate and reinforce the very inequities an organization is trying to dismantle. When you put shared leadership at the center — deliberately bringing in voices from across the institution, distributing both the work and the authority — you get representation in the room and at the table.
In 2024, CommonFuture’s Consensus, Collaboration, and Trust documented its own three-leader model for a multi-racial co-led organization’s guide to sharing power, continuing its commitment to experimentation, innovation, and transformation within. Their report provides one of the most helpful first-hand chronicles, and even addressed the skeptics:
“Regarding organizational bloat: Nonprofit work often asks us to be “scrappy and nimble” and live into the falsehood of martyrdom for respective causes. We asked, can we afford not to invest in best efforts?”
The field is asking hard questions about AI as team member
Perhaps the most emergent conversation in leadership research right now is this one: what happens to shared leadership when your team member isn’t human?
In February 2026, McKinsey & Company published its State of Organizations report, drawing on surveys of more than 10,000 senior executives across 15 countries. One in four leaders said they expect AI agents to act as autonomous team members in the near term — not as tools, but as active participants in how work gets organized and done.
The International Leadership Association is hosting a summit in May 2026 specifically to address how leadership and management practices change when team members are intelligent systems. How do you design workflows, decision rights, and coordination processes in that environment?
These questions matter for practitioners. Even with AI as our co-pilot, we are still paying attention to the underlying principles of shared leadership, aligned with Your Next Harvest’s RALR™ Co-Leadership Onboarding: clear Roles, upfront Agreements, scheduled Learning, and ritualized Repeat— to maintain trust and sustainability.
What this all means for co-leaders right now
Here are takeaways from 2026's emerging picture:
Shared leadership is maturing as a field. The research base is now large enough, as over 1,225 articles and book chapters have been published since 2000 — that shared leadership is a legitimate, evidence-based approach to organizational structure. If you are still making the case internally for a co-leadership model, the scholarship is on your side.
The mechanism matters as much as the model. It is not enough to split a title or divide a job description. Co-leadership works because it builds collective confidence in the team. How and whether you prepare the organization and stakeholders, onboard co-leaders, embrace learning and flexibility, and establish ongoing rituals can sustain or break the partnership. Structure is the starting point, not the destination.
Equity and co-leadership are natural partners. Organizations serious about belonging and inclusion, or liberation — depending on your lived experience and end goal — are increasingly finding that shared leadership models provide the structural expression of those values. If your organization talks about equity, shared leadership may be one of the most concrete ways to live it, and it can be lived out in multiple layers of the organization.
The human skills matter more, not less. As AI becomes embedded, the research is consistent: emotional intelligence, judgment, communication, and trust-building are becoming more valuable, not less. Co-leaders who have cultivated those capacities are well-positioned for whatever comes next.
A final thought
Twenty years ago, the researchers who first published on shared leadership may have had difficulty getting their work into the top journals. The idea may have been considered too far from accepted norms. Today, it is standard in the leadership lexicon — and the evidence that it can work, with best practices, is substantial and growing.
