The WNBA collective bargaining agreement restricts draft eligibility to women, with no male or former NBA player ever selected, creating the core barrier behind traders' 96.9% implied probability that none will be drafted in 2027. Recent declarations by Enes Kanter Freedom and Royce White, who cited self-identification language in league guidelines, have prompted commissioner acknowledgment and internal discussions but no eligibility confirmation or policy shift. Standard requirements such as the four-year rule for U.S. players and age minimums further complicate entry, while the league's historical enforcement of its women's category sustains market skepticism. Realistic scenarios that could alter the outcome include explicit rule clarifications allowing broader self-identification before April 2027 or successful legal challenges, though both remain unconfirmed and face significant institutional resistance.
