There really are markets in everything.

The Chinese ecommmerce site Taobao — part of entrepreneur Jack Ma’s Alibaba group — has made it illegal to bet on the length of Taylor Swift’s romantic relationships, specifically her most recent reported beau, British actor Tom Hiddleston.

Xinhua–the state run media over there–reports the betting began last week.

No word on the odds, but The Hollywood Reporter notes Swift’s romances average about two and a half months.
