Livestream commerce quietly hit its US inflection in H1 2026

This pulse is built on Momentum Works' tracking of TikTok Shop gross merchandise value (GMV), the cleanest public series on US social commerce. Three numbers are our own calculations. Implied H1 2025 US GMV is about $5.8B ($11.8B / 2.03). The FY2026 run-rate is about $26B ($11.8B for H1, plus $14.2B for H2 from a 20% seasonal uplift, $11.8B x 1.2). Creator-touched GMV in 2026 is about $15.6B ($26B x the 60% creator share measured in 2024). Livestream-specific figures come from third-party aggregators and are flagged low confidence throughout.

How fast did US TikTok Shop GMV grow in H1 2026?

US GMV reached $11.8B in H1 2026, up 103% year on year, according to Momentum Works. That is roughly double the implied $5.8B of H1 2025. The more important signal is the slope. Full-year 2025 grew 68%, from $9B to $15.1B, per Momentum Works' 2025 report. A market that accelerates from 68% to 103% growth at a $15B base has crossed from early adoption into mainstream behavior.

Rebase 2024 to 100 and the US market reads 168 in 2025 and 289 on the 2026 run-rate, a roughly 2.9x expansion in two years ($26B / $9B). The global picture points the same way. Tubefilter, reporting Momentum Works, puts TikTok Shop on track for about $112B in global 2026 GMV, up 70%, with the US leading growth.

How much of that volume is actually livestream?

The live-specific numbers are thinner but point the same direction. Dashboardly estimates US TikTok LIVE sales topped $3B over the trailing 12 months, with LIVE at about 26% of TikTok Shop GMV versus about 14% in 2024. That is an aggregator figure, so treat the exact share as directional. The trend, live taking a growing slice of a fast-growing pie, is consistent with everything else in the data.

Session-level economics explain why sellers are moving to live. TTS Vibes reports that TikTok Shop-managed LIVE sessions convert at about 10.4%, average about $12K per session, and hold buyers for about 22 minutes. Managed sessions are likely the top of the distribution, not the median. Even discounted heavily, those are conversion rates that static product pages rarely approach.

Why does this matter for creators rather than brands?

Because creators already route most of the money. US influencers generated $5.4B of TikTok Shop GMV through videos and livestreams in 2024, about 60% of the US total, per Contentgrip, citing TikTok Shop's 2024 recap. If that ratio holds, the ~$26B 2026 run-rate implies about $15.6B of creator-touched US GMV ($26B x 60%). The ratio is two years old, so the figure is directional. The structural point is not: in US social commerce, the creator is the storefront.

Where is the data strongest, and where is it directional?

The strongest numbers are Momentum Works' reported GMV figures: $9B in 2024, $15.1B in 2025, and $11.8B in H1 2026. The $26B run-rate depends on our 20% H2 uplift assumption, so it moves if holiday seasonality is stronger or weaker than modeled. The creator-touched estimate inherits a 2024 ratio and is the weakest of our derived numbers. Every LIVE-specific figure (the 26% share, the $3B TTM, the 10.4% conversion) comes from aggregators and carries low confidence. The next input we would plug in is a first-party LIVE GMV disclosure from TikTok, which would turn the livestream share from directional to measured.

The inflection was quiet because it arrived inside a single platform's half-year numbers rather than in a headline launch. But the arithmetic is plain: US social commerce doubled in a year, it is accelerating, and live video is taking a growing share of it.
