Google confirmed in December 2025 that it is "enabling third-party speaker devices as well" as part of Gemini for Home, adding "Third-party speakers" to its official compatibility list alongside every Nest and Google Home product, 9to5Google reported. That same month, Walmart's Onn 4K Pro became one of the first non-Google devices to receive the Gemini upgrade, per Android Authority. Walmart has not officially announced a Gemini-powered smart speaker, but a Connectivity Standards Alliance listing has now surfaced for an unreleased Walmart Onn Smart Speaker that appears to use Gemini rather than Google Assistant. That makes the question less theoretical than it was in late 2025.
What follows separates what Google has confirmed, what users have observed, and what remains unverified because those are three different things.
What Google confirmed: third-party speakers are in
Google announced Gemini for Home in August 2025 and began early access for Nest and Google Home devices in late October, per the Google Blog. Third-party hardware wasn't part of the original stated plan.
The December update changed that framing explicitly. Google's announcement read: "We're also enabling third-party speaker devices as well." The updated compatibility list reflects it, 9to5Google reported. By that point, US users could opt in to Gemini for Home early access and most would receive an invite within 24 hours. "Millions of households" now have access via smart speakers. The rollout began in the U.S., but availability has been expanding, and Google's support materials still frame Gemini for Home services as dependent on region and device compatibility.
That language is the clearest proof point. It confirms strategic intent, not just a technical accident.
What users observed: Gemini on abandoned hardware
Days before Google's official statement, users had already noticed something unexpected. Insignia and Lenovo devices from 2018 and 2019, long discontinued and no longer receiving regular updates, were quietly gaining Gemini for Home, Android Authority reported. The Insignia Voice Speaker, a Best Buy house-brand product that had already lost its iHeartRadio integration, responded to "Hey Google, who are you?" with a Gemini for Home identification, confirmed in user-recorded footage, per 9to5Google. Reports of the Lenovo Smart Clock series receiving the update were also circulating, though with less definitive evidence, 9to5Google noted.
These reports show a technical pathway exists. Google's official language confirms the strategic intent behind it. The user observations and the policy change are different kinds of evidence; the latter carries more weight, but the former arrived first.
What neither confirms is scope. It remains unclear whether Gemini third-party support covers all legacy Google Assistant hardware, a subset based on processing capability, or only devices whose manufacturers have re-engaged with Google on updated terms. Technical requirements and commercial agreements haven't been published.
Why the business model makes third-party expansion logical now
Google's third-party Assistant hardware push ran roughly from 2017 to 2020. Brands including Sony, Anker, Lenovo, and JBL shipped Assistant-enabled speakers under Google's licensing framework. Support was uneven, devices aged out of updates quickly, and Google shifted focus to the Nest line.
The Gemini-era approach is structurally different in one important way: the revenue model has changed. The base Gemini for Home upgrade ships free to compatible devices. Google Home Premium starts at $10 per month: Google says the Standard plan includes Gemini Live, Ask Home automation help, 30 days of video history, and intelligent camera alerts, while the $20-per-month Advanced plan adds AI event descriptions, Home Brief summaries, and searchable video history. That subscription tier didn't exist during the Assistant era.
That changes the calculus. Every additional Gemini-capable speaker in a home, whether made by Google or a retail partner, becomes a potential entry point into Google's paid smart home ecosystem, though specific features such as Gemini Live may still depend on device support, region, and subscription tier. The 24-hour invite window and "millions of households" figure suggest Google is actively trying to expand that installed base, as 9to5Google reported. Third-party hardware, in that context, isn't a concession; it's a growth channel.
Why a Walmart smart speaker with Gemini is worth watching out for
Walmart's Onn line already ships with Google software. It runs Google TV, launched with Google Assistant built in, and receives Google software updates through an established Android TV hardware pipeline. More recently, Walmart's updated Onn 4K Pro has appeared with Google Gemini support for hands-free voice control, search, and recommendations, plus Matter-over-Thread compatibility, according to The Verge. Some early users reported receiving Gemini on the Onn 4K Pro before seeing it on their Google Home devices.
That early-mover placement reflects a functioning software integration relationship, not just a retail shelf agreement.
It's worth being precise about what that proves. A streaming box with voice assistant behavior is a different product category from a dedicated smart speaker. An Onn-branded smart speaker would require its own engineering, certification, and go-to-market decisions that the 4K Pro rollout doesn't speak to directly.
What makes Walmart a more plausible candidate than other potential Gemini for Home third-party speaker partners Best Buy's Insignia line, Lenovo, or generic Android TV brands is the combination of an established Onn brand built around aggressive pricing, a Google software relationship already producing early-mover results, and the scale of Walmart's physical retail footprint.
That alignment between Walmart's hardware infrastructure and Google's subscription growth goals is the actual basis of the speculation. No Walmart retail page or FCC filing has surfaced yet, and Walmart has not officially announced the product. But a Connectivity Standards Alliance listing reported by Android Authority points to an unreleased Walmart onn. Smart Speaker with Gemini, Google Cast for Audio, Wi-Fi, Bluetooth, smart home controls, a 10W speaker, far-field microphones, physical controls, LED indicators, and a hardware microphone kill switch.
What to watch, in order of importance
The Gemini for Home third-party rollout is confirmed by Google, broader than initially indicated, and still expanding. The monetization infrastructure is in place. Walmart's Onn hardware has already appeared early in Google's Gemini and Matter-related TV rollout.
The first concrete signal has already arrived through the CSA listing. The next stronger signals would be an FCC filing, a Walmart.com product page, Google Home app support, or an official announcement from Walmart or Google. A Google I/O appearance or a Walmart hardware event would be the natural venue for a product in this category to surface publicly.
Track the broader Gemini for TV rollout as well. As of last December, the wider streaming ecosystem expansion may spill into this year, per Android Authority. How far that expands will signal whether Google is treating third-party Gemini as a genuine strategic priority or a limited compatibility exercise.
For readers thinking practically: third-party Gemini support now exists in a way it didn't a year ago. That means budget Gemini hardware could arrive through retail partners before Google ships a new Nest speaker. It also means older Google Assistant devices already in homes may gain meaningful capability through software updates alone — no new hardware required.
