Whatnot is a live-stream shopping marketplace, and YouTube interest for the keyword whatnot printed 57 the week of August 22 2026. That is up 18.75% from 48 on August 15 and up 128% from 25 on July 25, per Trends MCP get_growth on youtube. The 261-week get_time_series on the same source runs from August 28 2021 (first print 1) through August 22 2026. Native Android app downloads for com.whatnot returned no series. Google Search peaked at 100 on July 25 and sat at 82 on August 22, an 18% 30-day drop, so search is not the move. TikTok jumped 338.28% in 7 days, from 12.8 to 56.1, but that feed only has 30 daily points. The YouTube curve is the one that still climbs.
About Whatnot
Whatnot is a live-stream shopping marketplace where sellers auction goods on camera. Wikipedia lists Grant LaFontaine as CEO and Logan Head as co-founder, with a 2019 start in Marina Del Rey, California. The first inventory was Funko Pop figurines. Live shows arrived in 2020 and became the business.
TechCrunch covered a January 2025 Series E of $265 million at nearly $5 billion. The New York Times dated a $225 million Series F to October 28 2025, at $11.5 billion. CNBC, on August 7 2026, reported a $545 million Series G led by Iconiq, Lightspeed, and Avra that valued the company at $20 billion. Wikipedia says sellers moved $3 billion via live sales in 2024, then more than $8 billion in 2025, and that the company claimed nearly 60% of live commerce across North America and Europe that year. March 2026 brought a Shopify inventory sync and 15 arbitration claims over card "breaks." The company told The Athletic that gambling is not allowed and that breakers are 4% of sellers.
What the time series shows
YouTube interest for whatnot printed 57 on August 22 2026, the peak of the 261-week series. Last eight weekly prints are 21, 24, 26, 25, 28, 33, 48, and 57. Closest 30-day point is 25 on July 25 (+128%). Closest 90-day point is 19 on May 23 (+200%), which matches get_growth on the 3M window. Same week of the year: 12 on August 23 2025, 4 on August 24 2024, 5 on August 26 2023, 4 on August 27 2022.
The chart window starts August 24 2024 so two years of the slow grind stay in view. 2024 prints sit between 4 and 7. 2025 spends most weeks at 8 to 13, with a 16 on November 15. 2026 opens at 15 on January 3, touches 25 on February 14, 31 on June 20, then 33, 48, and 57 across the three August weeks. 57 is a new high, not a bounce under an old peak. The week-to-week path is a climb a stranger can read in one glance.

The Trends MCP calls for this keyword
get_time_series with source youtube and keyword whatnot is the call behind the chart: 261 weekly points from 2021-08-28 through 2026-08-22, stored as {date, value} with no smoothing. get_growth on the same pair, windows 7D and 30D, is the headline math: 48 to 57 (+18.75%) and 25 to 57 (+128%). The 3M window on that pair is 19 to 57 (+200%). Those tools have to share a source. Mixing the Google Search 82 with the YouTube 57 would invent a story the APIs do not tell. get_top_trends on App Store Top Free supplies the rank-26 context. The YouTube trends source page documents the 0-100 weekly index. The App Store Top Free API page is the board that still has Whatnot inside the top 30 free apps.
