Twitter raised roughly $4.46 billion from the IPO, based on the 171.6 million shares priced at $26, before over-allotment. The additional underwriter options increased the total raised if exercised. Companies typically allocate IPO shares across institutional investors, retail investors via allocations from brokerages, and sometimes employees exercising early grants.
