Will another Millennium Prize Problem be solved before 2028?

The Millennium Prize Problems are seven problems in mathematics that were stated by the Clay Mathematics Institute in 2000. The problems are:

• Birch and Swinnerton-Dyer conjecture

• Hodge conjecture

• Navier–Stokes existence and smoothness

• P versus NP problem

• Poincaré conjecture

• Riemann hypothesis, and

• Yang–Mills existence and mass gap.

A correct solution to any of the problems results in a US $1M prize (sometimes called a Millennium Prize) being awarded by the institute. The only solved problem is the Poincaré conjecture, which was solved by Grigori Perelman in 2003.
