I know that it has been mentioned here before, but what about creating a market for some of the monthly numbers that BLS releases like the unemployment rate, job growth, etc. Unemployment rate might not have enough market choices as in most months it won't change more than 0.2% over last month, but job growth you could easily do 5 different options (e.g. below 150K, 150-200K, 200-250K, 250-300K, 300K+)
Thank you very much for the suggestion! I will pass it along to our markets committee for future consideration.
