San Francisco-based Twitter is expected to file initial public offering papers as early as this week, according to the Wall Street Journal.

That means Twitter stock could begin trading in late October or early November if the offering goes as planned.

Twitter announced earlier this month that it had made a confidential filing with regulators. Its IPO is one of the most anticipated in recent years, but it's expected to be far smaller than Facebook's offering.

Private markets have valued twitter at around $10 billion.
