... increase in supply.

The prices of tickets for the Jazz game were selling at pretty high prices this early AM. All the sudden the supply of tickets for sale is 3x what it was just last night. Prices keep going up, so will supply of tickets for sale, and eventually by Friday early AM prices will be much lower (I'll forecast), because prices will be out of the range of the willingness to pay of those who want to attend, and there will be a large supply of excess tickets for sale.

Increase in price will always increase the supply. This is evident in the oil/gas industry if you need further proof.

Economics.
