Canalys predicts worldwide smart speakers sales will reach 56.3M in 2018, with 38.4M sales in the US, outpacing AR, VR, and wearables
Context & Ripple Effects
Canalys opened 2018 by calling smart speakers the fastest-growing consumer hardware category of the year — 56.3M units worldwide, 38.4M of them in the US, ahead of AR, VR, and wearables combined trajectories. The call landed mid-ramp: the category had roughly doubled its installed base from under 50M at end-2017 toward close to 100M devices in use by year-end.
Subsequent data validated the trajectory rather than correcting it. Q3 shipments came in at 19.7M globally, up 137% year over year, with the US and China together accounting for 70% of the market, and RBC's survey work showed US household penetration jumping from 21.5% to 41% of consumers owning a speaker in a single year, driven almost entirely by Alexa and Google Home devices.
First-order effects
- Amazon and Google, the two vendors behind nearly all of that US adoption per RBC's survey, get a category where unit volumes beat AR, VR, and wearables — justifying continued price-cutting and bundling to grow the installed base.
- Hardware makers betting on AR, VR, or wearables as their 2018 growth story face a market where the voice-first device is pulling consumer attention and shelf space instead.
Second-order effects
- China's emergence alongside the US as 70% of the global market forces Alibaba, Baidu, and Xiaomi-class players into a speaker race that was previously an Amazon-Google duopoly, pressuring component suppliers and pricing across regions.
- An installed base approaching 100M turns the speaker into a distribution channel — commerce, music, and smart-home vendors now compete for placement on Alexa and Google Assistant rather than for the living-room device itself.
Third-order effects
- If penetration keeps compounding the way RBC measured it — 21.5% to 41% of US consumers in one year — voice assistants become a default interface layer, and control of the assistant platform becomes worth more than the speaker hardware margin.
- The pattern points to smart speakers consolidating into a two-platform market with regional champions, echoing the smartphone structure rather than the fragmented wearables one.
The trend: Consumer hardware spending is rotating toward voice-first devices, with smart speakers outgrowing AR, VR, and wearables and turning assistant platforms into the next battleground after smartphones.
