Czech billionaire Daniel Kretinsky has emerged as the biggest shareholder at West Ham United after David Sullivan’s position was plunged into crisis by a misconduct scandal that has shaken the club’s ownership structure. Kretinsky, who already held a significant minority stake, has moved to increase his shareholding as pressure mounts on Sullivan, whose long-term control of the club now appears under serious threat.
Sullivan, for years the dominant figure in the boardroom, has faced intense scrutiny following historical allegations about his conduct away from football, prompting calls for a reassessment of his suitability as an owner under fit-and-proper rules. While Sullivan has strongly denied the accusations and vowed to clear his name, the fallout has created an opening for Kretinsky to expand his influence and take a leading role in West Ham’s future.
Kretinsky, whose business empire spans energy, logistics and retail, has steadily built his presence in east London since first buying into the club, positioning himself as a long-term investor ready to step in if the existing hierarchy faltered. With Sullivan’s stake now under scrutiny and his focus diverted by legal and reputational battles, sources around the club see Kretinsky as the de facto powerbroker at West Ham, shaping strategic decisions on finances, recruitment and infrastructure.
Supporters are watching developments closely, with some welcoming the possibility of new leadership after years of frustration over ownership decisions, while others are cautious about a shift towards another billionaire-led model. Fan groups have already called for transparency over any change in control, insisting that lessons be learned from past missteps and that the club’s identity and long-term stability remain at the heart of any restructuring.
For West Ham, the timing is critical: the club faces ongoing financial and competitive pressures, and any transition at the top will directly affect transfer plans, managerial backing and stadium strategy. As Sullivan battles to defend his reputation off the pitch, Kretinsky’s rise as the club’s biggest shareholder signals a new era in east London one that could redefine West Ham’s direction for years to come.
