Disclosed are various embodiments for speculatively generating network page components to reduce network page generation latency. A request for a network page is received. Speculative generation is initiated for multiple network page components that are capable of being included in the network page. A subset of the speculatively generated network page components that will actually be included in the network page is determined. The network page is then generated, where the subset of the speculatively generated network page components are included in the network page and others of the speculatively generated network page components are excluded from the network page.
