TikTok shows an average engagement rate of 2.60% against just 0.48% for Instagram, on a sample of 70 million posts analyzed (Socialinsider, 2026 Social Media Benchmarks, January 16, 2026). On paper, TikTok looks well ahead of Instagram. But raw engagement doesn't tell the full story for an agency or SME building a sustainable growth strategy. Between global audience, usage in France, ad cost, and regulatory context, each platform has its strengths and limits. This guide compares Instagram and TikTok point by point in 2026, with verified figures, to help you choose the right priority for your goals. Whether you manage a single account or several clients as an agency, the question isn't just "which network performs best," but "which network supports sustainable growth in your context."

Instagram vs TikTok in 2026: who leads in global audience?
Instagram is still used by 55.1% of connected adults worldwide each month, against 36% for TikTok (DataReportal / We Are Social, Digital 2026 Global Overview Report, October 13, 2025). This gap of nearly 20 points puts Instagram ahead of TikTok in stated global reach, despite the latter's rapid growth.
TikTok, however, keeps an edge in usage intensity. Users spend an average of 1h37 per day on it on Android, with nearly 10 daily sessions (DataReportal, 2026). In the global ranking of social apps by active users, Instagram ranks 3rd with a Similarweb index of 79.9, while TikTok comes in 5th with an index of 55.1.
These two figures tell different stories. Instagram wins on global reach and established presence. TikTok wins on daily usage intensity, a useful signal for anyone chasing pure visibility rather than an audience built to last.
For an agency that has to allocate its time and budget, this distinction matters more than the raw ranking. A wider, more established audience, like Instagram's, offers a more stable base for building a loyal community over several months, rather than a one-off spike in visibility.
Instagram and TikTok in France: which figures matter in 2026?
In France, Instagram is still used by 55% of internet users each month, with ad reach up 4.3% year-over-year (We Are Social, Digital Report France 2026, January 2026). TikTok is also growing, but stays behind, with 38.3% monthly users and 1h33 of daily time spent on Android.
TikTok's ad reach is also growing, by 3.3% year-over-year, a pace close to Instagram's (We Are Social, 2026). For an agency targeting the French market, Instagram therefore keeps a clear edge in available audience volume, even as TikTok gradually closes the gap.
This French dynamic confirms the trends observed across the whole platform. Our article on the major Instagram trends for 2026 details how these usage shifts are transforming content and organic growth strategies.
For an SME or agency mainly targeting the French market, this balance of power directly shapes the choice of priority channel. A limited budget is generally better spent focused on the platform where most of the available audience already is.
Which network generates the best engagement rate?
TikTok shows an average engagement rate of 2.60%, down 10% year-over-year, against 0.48% for static Instagram posts (Socialinsider, 2026 Social Media Benchmarks, 70 million posts analyzed, January 16, 2026). The gap remains wide, but it says nothing about the type of content that makes up each platform.
Video format changes the picture for Instagram. Reels generate engagement of 6.59% to 8.77% depending on account size, with an average of 120,917 views (Backlinko, eMarketer data, December 12, 2025). Instagram video posts also generate 3.15 times more likes than image posts, with 1,832 average likes against 581 (Backlinko, 2025).
Comparing an average engagement rate across all formats therefore hides a more nuanced reality. On Instagram, Reels-type video content largely rivals TikTok's raw performance, provided it's produced with the same demand for short format and an immediate hook.
Before concluding that one platform "performs better," compare your own Reels engagement rate to these benchmarks by account size, rather than to an all-format average that mixes photos, carousels, and videos.
| Metric | TikTok | Source | |
|---|---|---|---|
| Monthly users worldwide | 55.1% | 36% | DataReportal, 2026 |
| Monthly users France | 55% | 38.3% | We Are Social, 2026 |
| Average engagement | 0.48% | 2.60% | Socialinsider, 2026 |
| Ad CPM | $14.19 | $13.26 | Triple Whale, 2026 |
What ad budget should you plan for Instagram and TikTok?
The average CPM on TikTok reaches $13.26 in 2025, up 16% year-over-year, against a global median of $14.19 on Meta platforms (Triple Whale, TikTok Ads Benchmarks, updated March 24, 2026). TikTok remains slightly cheaper, but the gap is closing fast.
This CPM increase reflects a TikTok platform that's becoming increasingly competitive on the advertiser side, as ad demand rises there. For an agency budgeting a multichannel strategy, TikTok's historical price advantage is shrinking year after year. This weakens one of its main arguments against Meta's mature ad ecosystem.
In practice, many advertisers don't pick a single platform. They test a smaller budget on TikTok for awareness, while concentrating most of their spend on Instagram, where the conversion funnel (bio, Shopping, forms) remains more complete and better documented.
Reels or TikTok: which content format should you prioritize?
Content that works on TikTok and on Instagram Reels shares common codes: vertical format, fast pace, a hook in the first three seconds. This is a widely shared industry observation, without a verified primary-methodology study to quantify it precisely, but it guides content production on both platforms.
The difference mainly comes down to how content is discovered. On TikTok, content circulates mostly through an algorithmic feed built around interests, rather than around the user's network of relationships, a qualitative trend widely accepted in the industry rather than a published figure. On Instagram, the social graph (follows, discovery via followed profiles) still carries weight in distribution, alongside the algorithm.
For an agency, this means two different production logics. TikTok rewards volume and fast experimentation. Instagram rewards brand consistency over time, a key factor for turning an audience into a loyal community rather than just one-off views.
Adapting the same shoot for both platforms
In practice, the same vertical shoot can feed both platforms, as long as you adjust the edit. Keep the most fast-paced cuts for TikTok, where skipping is instant, and keep on Instagram the versions that better showcase your visual identity and your bio, the natural entry point to your offer.
Is TikTok facing regulatory uncertainty in 2026?
TikTok's US divestiture case closed on January 22, 2026. Oracle, Silver Lake, and MGX now each hold 15%, or 45% in total, while ByteDance retains about 19.9% of shares, under the 20% legal threshold (deal corroborated by Variety and three other independent sources, December 2025 to January 2026). TikTok continues to operate normally in the United States: there has been no ban.
In Europe, the European Commission published preliminary findings on July 24, 2026 stating that TikTok would not be complying with the Digital Services Act on the protection of minors' accounts, notably regarding public-by-default accounts (European Commission, Digital Strategy, July 24, 2026). This is a preliminary procedure, with no final decision or confirmed sanction at this stage.
This context doesn't condemn TikTok, but it introduces a structural uncertainty that Instagram doesn't have. Meta is not subject to either a forced divestiture procedure or an open DSA investigation on this topic. That currently makes it the more stable of the two platforms for building an organic growth strategy over several years.
For an agency committing a budget or production time over twelve to twenty-four months, this stability criterion carries as much weight as engagement figures. A sudden change of ownership or regulatory restriction can reshuffle the rules of the game overnight, a risk Instagram doesn't currently carry.
Instagram or TikTok: which network should you choose for a sustainable B2B growth strategy?
76% of B2B marketers cite LinkedIn as the most effective channel for their thought leadership content, well ahead of other measured channels like email newsletters (54%) or webinars (52%) (Content Marketing Institute, B2B Content and Marketing Trends 2026, October 2025). This study doesn't measure Instagram or TikTok with the same granularity, but it confirms that effective B2B is built on one dominant relationship channel, not a stack of platforms.
At Propulse, we see this choice confirmed on the ground: agencies managing a B2B or services clientele get better conversion into qualified appointments via Instagram, where the profile and bio format allows for a more direct buying journey than on TikTok.
This doesn't mean ignoring TikTok, especially for B2C awareness or a younger target. But for a sustainable organic growth strategy, backed by a mature ad ecosystem and a stable regulatory context, Instagram remains the recommended foundation. Discover how Propulse's Instagram organic growth features fit into this strategy.
Should you be present on both platforms?
Nothing stops you from testing TikTok as a complement, especially if your target is young or mass-market. But for an agency or B2B SME with limited resources, it's better to consolidate one channel before opening a second. Instagram, with its wider audience and complete ad ecosystem, remains the safest starting point.
How Propulse helps you put all this into practice

Instagram or TikTok, which network has more users in 2026?
Instagram is still used by 55.1% of connected adults worldwide each month, against 36% for TikTok (DataReportal, 2026). In France, the gap is similar, 55% against 38.3% (We Are Social, 2026). TikTok partly makes up for it with stronger usage intensity, with 1h37 of average daily time spent on Android.
Does TikTok have a better engagement rate than Instagram?
Yes, on raw data across all formats: 2.60% against 0.48% (Socialinsider, 2026). But Instagram Reels reach 6.59% to 8.77% depending on account size, a level comparable to TikTok (Backlinko, 2025).
Is TikTok banned in the United States in 2026?
No. The divestiture case closed on January 22, 2026, with Oracle, Silver Lake, and MGX as majority shareholders and ByteDance under the 20% legal threshold. TikTok continues to operate normally in the country.
Which network costs less for advertising, Instagram or TikTok?
TikTok shows an average CPM of $13.26 against $14.19 on Meta, but the gap is narrowing: TikTok's CPM rose 16% year-over-year (Triple Whale, 2026).
Why choose Instagram over TikTok for a B2B strategy?
Available B2B studies don't compare Instagram and TikTok head to head, but they confirm that one dominant relationship channel works better than spreading effort across several platforms (Content Marketing Institute, 2026). Instagram also benefits from a more stable regulatory context, with no divestiture procedure or DSA investigation underway, a significant factor for a content investment spanning several months.
