open letter against Saudi Arabia's bid to host the 2022 World Science Fiction Convention, citing human rights abuses and discriminatory laws. Chengdu, China will host the 81st Worldcon in 2023. It will be the second Worldcon to be held in Asia after the 65th Worldcon in Japan in 2007. The 82nd Worldcon will be held in Glasgow, Scotland in 2024. The only bid for the 83rd Worldcon for 2025 is Seattle, Washington. Jeddah, Saudi Arabia reasserted its bid for 2026, but the bid has since been replaced by one for Cairo, Egypt. Convention committees As WSFS itself is an unincorporated society, each Worldcon is organized by a separate committee (usually) legally incorporated in the local jurisdiction; in the United States, these are usually organized as 501(c)(3) non-profit corporations, while in the United Kingdom, they are usually operated by companies limited by guarantee. The local organizers may be standalone, one-time committees (organized to hold the one event and then disbanded afterwards), or they may be organized by an existing local group. A few groups, such as MCFI in Boston, SFSFC (San Francisco Science Fiction Conventions, Inc.) in northern California, and SCIFI (Southern California Institute for Fan Interests Inc.) in southern California are permanent corporations established to manage Worldcons (or other one-off or rotating conventions) in different years in the same geographical area. Like most non-media science fiction conventions, all Worldcons are managed entirely by volunteers, with no paid staff. Senior committee members typically devote hundreds of hours (not to mention thousands of dollars in travel expenses in some cases) in preparation for a particular convention. While each convention is managed separately by the local committee, an informal and self-selected group of volunteers constitute the "Permanent Floating Worldcon Committee" who volunteer for many Worldcons in different years; this group offers a measure of institutional continuity to otherwise disparate legal organizations. Recent Worldcons have had budgets running in excess of a million dollars. The main source of revenue is convention membership, but Worldcons also collect fees from exhibiting dealers and artists and advertisers in publications, and some conventions manage to attract sponsorships of as much as 5% of total income. The main expenses are facilities rental and related costs, then (if possible) membership reimbursements to program participants and volunteers, then publications, audiovisual equipment rental, and hospitality. Traditionally, all members (except for guests of honor) must pay for their membership; if the convention makes
