Open the Draft of the ICANN Operational Plan, turn to page 15, and then look at the column titled "Resources Required." This is the cost of a new gTLD application. At the public forum on the Operational Plan, I said that this looked like about $250,000. The answer was that $250,000 was about right, but the actual number will depend on the outcome of the GNSO policy process. This is five times higher than the application fee required from Afilias and Neustar and Global Name Registry and the other new registries accepted in November, 2000. If you're interested in this, you ought to participate in the new gTLD policy processes (and perhaps comment on the ICANN Operational Plan). The cost of a new gTLD application will be directly proportional to the complexity of the new gTLD evaluation process.
