A similar race is on around China's Alibaba, which is expected to raise more than $15 billion this year. Bank chief executives such as JPMorgan's Jamie Dimon and Citigroup Inc's Michael Corbat have made it a point to meet Alibaba founder Jack Ma.

Twitter's debut, though much smaller than Facebook's, could generate tens of millions of dollars in fees from the underwriting mandate itself. Assuming it sells around 10 percent of its shares, or $1 billion, underwriters could stand to divide a fee pool of $40 million to $50 million, assuming an overall fee cut of 4 percent to 5 percent, according to Freeman & Co.

But the benefits for banks that underwrite the deal would likely be far-reaching.

Twitter is allowed to file its registration statement confidentially due to the Jumpstart Our Business Startups (JOBS) Act, a 2012 law that loosened some of the regulations surrounding the IPO process and other forms of capital raising.

Companies that file under that law do not have to reveal certain details until 21 days before embarking on an investor roadshow.

It could allow Twitter to avoid some of the harsh public scrutiny that other tech companies such as Groupon Inc faced.

Meanwhile, Silicon Valley boosters who were left red-faced by Facebook's stumble are hoping that Facebook's recovery and a smooth Twitter IPO would turn investor sentiment back toward consumer Internet companies.
