Naomi Osaka is leaving IMG to launch her own sports agency with Stuart Duguid, her representative since 2019. The move puts one of tennis's highest-earning athletes—$53 million in off-court income in 2023, per Forbes—in direct control of her commercial apparatus and positions Duguid to build a roster outside the WME-owned conglomerate.

Osaka and Duguid will operate the new entity independently, handling representation, endorsement negotiation, and licensing for Osaka's existing portfolio—Nike, Louis Vuitton, Lululemon, Mastercard, Nissan, Panasonic, Sweetgreen—and for any future clients Duguid signs. IMG, which absorbed Duguid when it acquired Essentially Sports Management in 2022, loses the commission stream but retains relationships with Osaka's brand partners across its broader talent and event divisions. The agency confirmed the departure, characterizing it as amicable.

The separation reflects a structural shift in athlete representation: stars with diversified income streams increasingly see agency commissions—typically 10-20% of endorsement deals—as extractive rather than value-additive once the initial relationships are secured. Osaka earned roughly $1 million in prize money in 2023 but ten times that from Nike alone. Her skincare line, Kinlò, and her majority stake in pickleball team Los Angeles Ships add equity upside that traditional agencies cannot monetize directly. Running her own shop means Duguid's economics are tied to Osaka's growth, not WME's margin targets.

For Duguid, the bet is that Osaka's infrastructure—legal, finance, brand strategy—can support additional athletes without IMG's overhead. If he signs two or three marquee names, the agency becomes a credible boutique. If he signs ten, it becomes a mid-market competitor. The timing is intentional: Osaka is preparing for a full 2025 season after maternity leave, and her ranking climb—she is projected to return to the top 50 by mid-year—will refresh sponsor interest and open new categories. Duguid wants to own that cycle outright.

Osaka's brand work has always skewed long-term. She joined Nike's board in a brand-building capacity in 2021, rare for an active athlete. Lululemon extended her deal in 2023 despite limited match play. Louis Vuitton kept her in campaign rotations through injury. These are relationships built on patience and cultural alignment, not tournament results. The independent agency allows her to formalize that approach: fewer clients, deeper integration, equity participation where possible.

Watch for Duguid's first external signing, likely within six months. He has relationships across women's tennis and Olympic sports from his IMG tenure. A second name—ideally in a complementary category like track, soccer, or action sports—would signal ambition beyond a single-client vehicle. Osaka's media company, Hana Kuma, is already producing content for Netflix and ESPN; the agency could bundle representation with production deals. Nike's next fiscal year ends May 2025, and any renewal or expansion of Osaka's contract would set the valuation benchmark for the new shop.

The broader market will read this as validation: if Osaka can unbundle, others will try. The agency model that worked in the 1990s—one firm, every sport, global scale—loses relevance when athletes have eight-figure social followings and direct-to-consumer channels. Duguid is not building the next CAA. He is building the infrastructure Osaka needs to be worth $100 million in equity by 2030, and he is betting three or four other athletes want the same math.
