Congratulations on hitting your milestone.
If you live in the U.S. and think inflation is around the corner, you can buy TIPS, treasury inflation protected securities. Due to the way they are taxed they are best held in retirement accounts.
Buying other web sites or domain names can be a good investment. You can buy them to make money as well as drive traffic to your other sites. I don't find a lot of good deals, though. A lot of the stuff on the auction sites is just junk.
