The Singapore Tennis Open (STO), the country’s premier professional women's tennis tournament, is entering an exciting new chapter in 2026.
Following a successful return to the Women's Tennis Association (WTA) Tour last year, the tournament has been upgraded from WTA 250 to 500 status, the first of its level on the city’s shores.
While the event made its long-awaited return last year after more than three decades, its history stretches back to 1986, when it was first established as the Singapore Women's Open. The tournament was held until 1994 before returning last February.
