If you weren't paying close attention in late 2024 and early 2025, you can be forgiven for thinking the TikTok US situation is resolved. It kind of is — the app is still operational in the US, the ownership structure got rewritten in a way that I'm not qualified to explain the legal nuances of, and the average American user's experience is more or less unchanged. Advertisers can still run TikTok ads. Budgets can still flow through TikTok Ads Manager. The doomsday scenarios from that period didn't play out.
But something did play out, and it's one of the most interesting budget-reallocation stories of the decade, and almost nobody has written about it accurately. During the uncertainty period — roughly October 2024 through the end of Q1 2025 — US advertisers collectively pulled an estimated $1.8-2.4 billion in planned TikTok spend and redirected it to other channels. That's real money. Much of it came back to TikTok after the situation stabilized, but a meaningful percentage didn't. And where it went is instructive about where the next wave of paid social budget is going to flow, regardless of what happens to any one platform.
This is not a post about TikTok. It's a post about what a brief stress-test revealed about the structure of the paid social market, and what I'm doing with that information in 2026.
What every agency predicted would happen
At the time, the prevailing narrative — stated with varying degrees of confidence in industry trade publications — was that TikTok budget would migrate cleanly to Reels and YouTube Shorts. This made sense on paper: same format (short vertical video), similar audience behavior, established alternatives. If you were a Fortune 500 CMO planning your 2025 contingency, this was the default assumption.
The reality was a lot messier, and I know because I was helping clients execute these reallocations in real time. Here's roughly where the money actually went, based on what I saw across my client book and what agency contacts shared with me in off-the-record conversations during that period.
Meta (Reels + Feed): ~45% of reallocated TikTok budget. Meaningful, but less than predicted. Meta was the obvious beneficiary and captured a plurality but not a majority. Two things suppressed Meta's share: creative mismatch (a lot of TikTok-native creative didn't perform well when directly ported to Reels, which caught advertisers by surprise), and CPM inflation (Meta's auction got noticeably more expensive in Q4 2024 as budgets flooded in, which reduced ROAS and caused some advertisers to rethink the allocation before fully committing).
YouTube (Shorts + Demand Gen): ~15% of reallocated budget. Less than predicted by most analysts, and the reason was interesting — YouTube Shorts' ad inventory was still relatively immature for direct-response advertisers at that point. Brands that moved budget to YouTube largely moved it to Demand Gen (the format formerly known as Discovery) and full-length YouTube video, not Shorts specifically.
Snapchat: ~8% of reallocated budget. Modest in absolute terms but large relative to Snapchat's baseline ad revenue. Snapchat had the closest creative parity to TikTok — vertical video, AR features, similar demographic — and a meaningful cohort of direct-response advertisers who had been running TikTok-first creative found Snapchat's Spotlight format to be a genuine alternative. This was the surprise beneficiary of the period.
Pinterest: ~5% of reallocated budget. A sleeper winner. Pinterest had spent 2023-24 repositioning as a lower-funnel purchase intent platform, and the TikTok uncertainty accelerated advertisers' willingness to test it. Pinterest's ROAS numbers during Q1 2025 looked exceptional, partly because of incremental spend from advertisers who had never seriously tested it before.
Connected TV / CTV: ~12% of reallocated budget. This was the most structurally significant shift. Advertisers — particularly larger brands — who were uncertain about short-form vertical video as a category responded by pulling budget up the funnel rather than sideways. CTV platforms (Roku, Samsung Ads, Disney+, Netflix Ad Tier, Hulu) absorbed a meaningful chunk of what would have been vertical-social spend. Once this budget moved, a lot of it stayed there.
Google Search and Performance Max: ~10% of reallocated budget. The boring answer, and it's always a bigger part of the story than people admit. When advertisers lose confidence in a top-of-funnel channel, a significant chunk of that spend gets redirected to bottom-of-funnel intent capture, even though the two are not substitutes.
Offline / brand / "retained in reserve": ~5%. Small but worth noting because it's the part of the reallocation that never came back to digital. A subset of large advertisers treated the uncertainty as a signal to shore up brand measurement and invested in things like OOH, TV, and brand tracking surveys.
What this tells us about 2026
A few things, and they're worth thinking about even if you have no specific interest in TikTok:
The short-form vertical video category is more fragile than advertisers pretend. When one major platform wobbled, the budget didn't flow cleanly to substitutes. It diffused into a dozen different channels, and about a third of it went to formats that aren't vertical video at all. This suggests that the specific creative-plus-platform fit matters more than the category, and advertisers should be running real platform-substitution tests rather than assuming creative is portable.
Pinterest and Snapchat are underweighted in most media plans. I had clients — good operators, thoughtful media plans — who discovered during the reallocation period that they were leaving meaningful ROAS on the table on Pinterest and Snapchat. Not because those platforms had gotten dramatically better, but because the clients had simply never run enough budget through them to know. If you're not testing $5-15K/month on each of Pinterest and Snapchat, you're probably missing an incremental channel, and the TikTok reallocation proved it at industry scale.
CTV is now where mid-market brands that aren't sophisticated enough for "real" TV end up. The CTV inflow during the reallocation period was disproportionately from brands that had never bought traditional TV. CTV ad platforms (especially Netflix's and Disney's ad tiers) have gotten easy enough to buy that they're now in the consideration set for brands spending $100K/month-plus on digital. This is a genuine shift and it's going to continue in 2026.
Platform diversification is undervalued. The clients who came out of the reallocation period in the best shape were the ones who had maintained active presences on 4-5 social platforms rather than concentrating 80% of their spend on one or two. This is counterintuitive — concentration usually produces better efficiency in steady-state — but it produces dramatically better resilience in stress-test scenarios, and 2024-25 proved that stress-test scenarios happen.
How I'm advising clients in 2026
Concretely, here's what I'm building into media plans this year:
Maintain active presence on at least four paid social platforms, even if three of them are at minimum viable spend ($3-5K/month). The insurance premium on platform diversification is cheap; the cost of concentration surprises is not.
Build creative strategies that are intentionally cross-platform — a creative system that produces Meta Reels, TikTok, YouTube Shorts, Snapchat Spotlight, and Pinterest Idea Pins from a shared base — rather than hiring a "TikTok agency" and a "Meta agency" with different creative pipelines. The ability to quickly shift budgets across platforms without creative lag is now a competitive advantage.
Treat CTV as a mainstream channel in any account spending above $75K/month. The buying platforms have matured, the measurement is less terrible than it was, and the inventory is absorbing significant budget from digital. Not testing it at this point is a strategic decision, not a technical limitation.
Run at least one quarterly "platform holiday" test — intentionally pulling 20-30% of budget from your largest platform for two weeks and measuring the business impact directly. It's the only way to know what that platform is actually worth to you in incremental terms, versus what its reported ROAS claims.
The TikTok saga was a preview of a kind of disruption that's going to keep happening. Not the specific geopolitics — that was idiosyncratic — but the general pattern of a major platform becoming uncertain, budgets reallocating messily, and advertisers discovering things about their media mix they should have known already. You want to be the operator who discovers those things on a quiet Tuesday in a planning meeting, not on a Thursday afternoon when your CMO forwards you a news alert.
If your media plan is over-indexed on one platform, that's exactly the conversation I have with clients in the opening weeks of every engagement. Or read my take on the AI Overviews traffic collapse for another angle on how advertisers are being forced to restructure in real time.
