As long as people are going short, banks have incentive to keep the price high and rake in the interest, using it to keep inflating the price. Only when everyone has stopped believing the price will go down and stops short selling, then the banks can no longer inflate the price and will let it go down. See oil for an example.

Welcome to the rigged game.

and assuming you can find shares to short, and are willing to pay the borrow cost.

During the first 30 days after an IPO, the underwriters are not allowed to lend shares for short sale. Additionally, number of shares are limited. The entire float is not available on the first day of trading. So today, it is probably impossible to short. 30 days from now, it should be available to short.

I've heard that larger banks and brokerages (not the underwriters) will start making shares available for shorting as early as Tuesday, which should help ease the share price down.

put options?

Options are available for trading only after a certain number of days (generally 60 to 90 days, but in some cases much earlier than that).

There always is.

Not always. There are some companies that don't have enough liquidity to effectively make that trade or have no investors willing to lend the shares. Not to mention shorting (or options) aren't even allowed yet on this particular stock.

But in this case there is almost a certainty that people would accept your short. I would.

except that's not how shorting stock works. it's not a person-to-person deal.

If you want to know, I tried shorting it at 110 just for the heck of it. tdameritrade says 'this stock not available for short sell'.
