Airbnb Peer Marketplace (2008)

Class card for Airbnb as a peer accommodation marketplace — the canonical DM-Day asset-light lodging platform. Founded August 11, 2008 in San Francisco by Brian Chesky, Joe Gebbia, and Nathan Blecharczyk as "AirBed & Breakfast" (air mattresses in their SoMa loft rented during the 2008 SF Democratic National Convention design conference). Y Combinator W09 batch. The defining structural innovation: hosts bear all property costs off Airbnb's balance sheet via independent-listing model, enabling near-zero marginal cost of supply expansion — the canonical DM push motor layered over an emergence dynamic (hosts self-organize supply without Airbnb direction). The trust/verification semiotic layer (host profiles, star ratings, review system, Superhost certification) constitutes Airbnb's core OPP: travelers cannot access peer-lodging supply without routing through Airbnb's identity-verification and reputational layer. International expansion 2011–2015. ~$120M Series A 2011 (Andreessen Horowitz). Airbnb Experiences launched 2016 (activity-booking vertical). Airbnb Plus (curated 2018). COVID pivot 2020: pivoted toward longer-term stays, work-from-anywhere demand, rural inventory. IPO December 10, 2020 (ABNB Nasdaq; $68/share offering price → $146 close → ~$100B peak market cap day-1; actual day-1 close ~$47B–$100B depending on fully-diluted basis). ~7M+ listings 2024. $10.9B revenue 2024. Regulatory pushback: NYC Local Law 18 (effective Sept 5, 2023) requires host registration + in-person presence, effectively prohibiting entire-apartment short-term rentals under 30 days — Airbnb NYC listings fell >80% post-enforcement. Barcelona mayor announced phase-out of all 10,101 tourist apartment licenses by Nov 2028 (June 2024). Paris implemented strict registration + rental-night caps. EU Short-Term Rental Regulation (2024) mandates host registration across member states. Hotel industry impact: Barron, Kung + Proserpio (Marketing Science 2021) find ~0.018% rent increase per 1% Airbnb listing increase in US cities; ~$2B/yr hotel-revenue diversion at peak; 10–15% lodging market share in major US cities. Racial discrimination findings: Edelman, Luca + Svirsky (AEJ:Applied Econ 2017) document ~16% callback penalty for African-American-sounding host names. V0.2 GAP: tep_phase trajectory irruption→frenzy→turning_point not capturable as single enum field; recorded here. Motor=emergence (primary) + push (secondary/atlas) per atlas DM-10 seed. dm_current=late_modernity (energetic zombie: massive listing-count growth, evolutionary intelligence withdrawing as municipalities close short-stay regulatory gaps). heavy_or_light=light (host properties off-balance-sheet — canonical asset-light DM platform).
