But Pinterest itself warned of slower growth from ad competition, and October 29 earnings will say which force wins. [Meta](https://theinference.org/markets/companies/meta) slammed the door on October 8, banning [ByteDance](https://theinference.org/markets/companies/bytedance), TikTok's parent, [from buying ads on Facebook and Instagram in the US, Canada, Egypt, Indonesia, Japan, Thailand and Vietnam](https://www.msn.com/en-us/technology/tech-companies/meta-bans-tiktok-ads-on-its-platforms-in-us/ar-AA2dQZbB), and the ban extends to any advertiser linking to TikTok [1]. TikTok's user-acquisition budgets did not disappear. They moved, and the first post-ban week shows where: [Sensor Tower's allocation estimates, published October 21](https://www.businessinsider.com/tiktok-pivots-ad-dollars-youtube-and-pinterest-after-meta-ban-2026-10), show the share of TikTok's ad spend landing on [Pinterest](https://theinference.org/markets/companies/pinterest) tripling to 9% between October 9 and 16, from 3% in the first week of October [2]. That is a windfall landing on a company that just told investors to expect less. [Pinterest warned in October that quarterly revenue growth will slow](https://www.cfoobserver.com/articles/pinterest-flags-slower-revenue-growth-as-ad-market-tightens-bb9f4549), blaming intensifying competition for advertising budgets, without naming rivals or quantifying the pricing pressure [3]. The windfall is one advertiser. The pressure is the whole market. ## Pinterest is the third stop, not the first Pinterest's redirect is real but small. [YouTube](https://theinference.org/markets/companies/alphabet), a far larger destination, took 17% of TikTok's spend in the post-ban week, up from 9%, and mobile-app ad networks like Google's AdMob took 58%, up from 19% [2]. Pinterest is the third stop, not the first. *Chart: **TikTok's spend shifted hardest to ad networks; Pinterest tripled but stayed third** Grouped columns showing TikTok's ad spend share by destination before and after Meta's ban: Pinterest 3% to 9%, YouTube 9% to 17%, mobile-app ad networks 19% to 58%.* *Share of TikTok's ad spend by destination, the week to Oct. 7 versus Oct. 9–16, per Sensor Tower allocation estimates after Meta's Oct. 8 ban.

On October 16, Pinterest [announced a partnership with tvScientific](https://adtechsumo.com/news/pinterest-expands-into-connected-tv-with-tvscie-fe19b4) to put its ads on connected TV, opening the fast-growing streaming market to its advertisers [4]. And it named [Amazon](https://theinference.org/markets/companies/amazon)'s James Dibbo as its new CFO, a hire the trade press read as a response to a softening ad market [4]. *Chart: **Pinterest has grown revenue for 12 straight quarters; Oct. 29 tests the run** Columns of Pinterest's quarterly revenue from Q3 2023 to Q2 2026, rising from $0.76 billion to $1.18 billion with seasonal peaks in each fourth quarter.* *Pinterest's quarterly revenue in US$ billions from its SEC filings; year-over-year growth has ranged from 11% to 23%.

[6]* Both camps get their number on October 29, when Pinterest [reports third-quarter results after market close](https://www.businesswire.com/news/home/20261019534697/en) [5]. The report either shows the redirected TikTok dollars offsetting competitive pressure, or it confirms Pinterest's own warning. Until then, the honest position is that a forced advertiser is a tailwind, but a tripling of one advertiser's share is a rounding error next to pricing power eroding across the sector. Pinterest told the market what to fear; October 29 tells it how much [5]. ## Takeaway Pinterest's share of TikTok's ad spend tripled to 9% in the first week after Meta's ban, but YouTube and ad networks took more, and Pinterest's own warning on ad competition makes its October 29 earnings the real test. ## Sources 1.
