Threads is the safer default for most brands in 2026: it is bigger by the only figures either company publishes, it costs nothing to post to, and its audience comes attached to your Instagram following. X remains the better choice for real-time news, link-driven traffic and any audience that simply has not moved.
The awkward part of this comparison is that only one side publishes numbers.
How many people use each one?
Meta said Threads crossed 500 million monthly actives on its Q2 2026 earnings call. X stopped publishing user figures after it went private, so any current X number you see is an estimate from an outside analytics firm, not a company disclosure. We are not going to print one as if it were fact.
That asymmetry is itself useful information. You can plan around a figure a public company has to stand behind. You cannot plan around a third-party panel estimate.
| Threads | X | |
|---|---|---|
| Audience | 500 million monthly actives (Meta, Q2 2026) | Not published since the company went private |
| Post length | 500 characters | 280 characters, more for paid accounts |
| Video | Yes | Yes, longer limits on paid tiers |
| Links | Allowed, historically down-ranked | Allowed, historically down-ranked |
| API for posting | Threads API, free, Meta app review required | Paid access tiers, free tier is minimal |
| Monetisation | Meta creator programmes | Ads revenue share for paid subscribers |
| Suits | Brands with an Instagram audience, conversation | Breaking news, real-time, established followings |
Note: Figures here were verified against Meta’s Q2 2026 earnings call (July 2026) and each platform’s own help centre and developer documentation as of September 2026. Platforms change these without notice.
Which gets more reach for a new account?
Threads, in almost every case, and for one structural reason: it imports your Instagram graph. A brand new Threads account belonging to an established Instagram account does not start at zero followers. On X, a new account starts at zero and stays there for a while.
The exception is an account that already has a large X following built up over a decade. That following does not transfer anywhere, and abandoning it because the platform is out of fashion is a bad trade. If you have it, keep posting there.
What about the API?
This is the clearest practical difference for anyone automating.
The Threads API is free to use. The cost is Meta’s app model: a developer app, permission review, and a long-lived token you have to refresh on a schedule. It is bureaucracy rather than money. The full walk-through is in our Threads API guide.
X charges for API access in tiers, and the free tier is small enough that it is really only useful for testing. If posting through the API is central to what you are building, price that in before you design around it. We covered what the official documentation states, and what it does not, in X API pricing and limits.
For a small brand posting by hand, that difference does not matter. For anything programmatic it can decide the whole question.
Do links work on either?
Both platforms have a history of showing link posts to fewer people than text or native media. Neither documents a penalty, so treat this as an observed pattern rather than a rule, and test it on your own account rather than trusting anyone’s blog post about it.
The workaround people use on both is the same: put the substance in the post, and the link in a reply or in the profile. That works better than arguing with a ranking system.
If you are measuring which platform actually sends you traffic, tag the links properly rather than guessing. The UTM link builder will do it consistently.
Should you post to both?
Usually yes, because the content is nearly identical in shape. Text and images move between the two without adaptation, apart from the length ceiling: X’s 280 characters is the tighter of the two for a standard account, so write to that and Threads will take it unchanged.
The failure mode is posting the same thing at the same second on both and having it read like a bot. A small stagger and a slightly different opening line is enough to avoid that. Our general take on when duplication helps and when it hurts is in what is cross-posting.
The verdict: who should pick which?
Pick Threads if you are starting now, or if your audience is on Instagram. It is the only one of the two where a new account has a realistic path to an audience, and it is free to post to programmatically. For most consumer brands in 2026 this is the default.
Pick X if you sell to a real-time audience. News, politics, finance, sport, developer tooling and anything where the conversation happens as events unfold. X still owns that reflex, and nothing has replaced it.
Keep X if you already have a following there. Reach you have already paid for is not something to walk away from because a competitor is growing.
Do not pick either if your content is visual and long-form. These are both text-first networks. A brand whose actual product is video or imagery gets more from Instagram, TikTok or YouTube, and should treat text networks as a secondary channel.
The short version
Threads is bigger by the only published figure, free to automate against, and comes with an audience if you already have one on Instagram. X does not publish user numbers any more, charges for API access, and remains the place where real-time conversation happens. Most brands should post to Threads by default and keep X if they already have an audience there. Write to 280 characters and both will take the same text.
Scheduling both from one queue
BulkPublish publishes to Threads and X alongside 13 other networks, so the same post can be queued to both with a stagger and a per-platform text override where the character limits differ. Failures on one platform do not silently take the other down with them. See scheduling.
