The 2026 Credit One Charleston Open, North America’s largest women’s-only professional tennis event, will award a record $2.5 million to players—$2.3 million in prize money and $200,000 toward player benefits—doubling its 2025 investment and making Charleston the first standalone WTA 500 to proactively boost its purse.
This milestone comes after Credit One Bank extended its title sponsorship through 2031 and committed to equal prize money starting in 2026, reflecting a strong belief in supporting women athletes at the highest level.
