The Singapore Tennis Open (STO), the top professional women's tennis tournament in the region, is entering an exciting new chapter in 2026.
Following Singapore's successful return to the Women's Tennis Association (WTA) Tour calendar last year, the tournament has been upgraded from WTA 250 to 500 status.
Singapore has had a long history with women’s tennis, stretching back to 1986 when the Singapore Women’s Open took place, and then with the WTA Finals from 2014 to 2018, where the WTA Tour’s crown jewel event featured the top eight players of the year at the Singapore Indoor Stadium.
