Amazon says there are now 40K Alexa Skills, up from 25K in December and 10K in February 2017, and makes in-skill purchases generally available in the US

Context & Ripple Effects
The skill-count race has been Amazon's headline metric for over a year: from 7K+ skills in January 2017 to 15K by mid-year, then 25K in December, when Voicebot flagged that growth was slowing. Today's 40K figure reaccelerates the curve — and pairs it with something new: in-skill purchases going generally available in the US, giving developers a way to earn money inside Alexa for the first time at scale.
That matters because the catalog gap is already enormous — when Alexa passed 15K, Voicebot counted just 378 voice apps on Google Home and 65 on Cortana. Monetization is Amazon's answer to the next phase: keeping developers building as raw novelty wears off.
First-order effects
- US Alexa developers can now sell content and subscriptions inside their skills rather than relying on Amazon's earlier limited-purchase programs, turning the 40K-skill catalog into a direct revenue surface.
- Amazon converts its distribution lead into a lock-in tool: with Google Home and Cortana an order of magnitude behind on voice apps, developers chasing paying users have one obvious platform.
Second-order effects
- Google and Microsoft face pressure to match in-app purchasing for their assistants or concede the paid-voice-app market before it forms elsewhere.
- A 40K-strong catalog sharpens the discovery problem — with more skills than any user will browse, ranking and promotion inside Alexa become valuable placement that Amazon controls.
Third-order effects
- Voice computing is following the mobile-app playbook: platform owners who control both the storefront and the payment rail capture the economics, while developers compete for discoverability rather than distribution.
- If the pattern holds — Voicebot later counted 56,750 US skills by year-end 2018 — the industry shifts from measuring assistant capability by skill counts to measuring it by developer earnings and retention.
The trend: Voice assistant platforms are moving from land-grab skill counts to monetized app economies, with whoever owns the payment rail — currently Amazon — setting the terms.
