Oh, interesting. I looked up recent IPOs on Nasdaq and ones from last month have options now. First Data (FDC) has been trading only 3 weeks and has options. But really low volume and ridiculous spreads. RACE has been trading only 3 weeks for less time and has more options. Perhaps they are exceptional due to their size?
Not that this would help with FB a whole lot since it'd have dropped a fair amount by the time you could buy options.
The rules aren't based on time, but basically on diversity of shareholders (there need to be a lot of shareholders and a lot of shares outstanding) which makes sense.
You need 7m publicly held shares outstanding (many IPOs don't do this, a lot of shares are controlled by underwriters and insiders who can't sell at the IPO) at least 2,000 shareholders and some minimum trade volume. There's a minimum share price too, but that doesn't effect IPOs.
