“The social media platform formerly named Twitter is still officially called Twitter rather than X.”
The conclusion
Official records and current platform listings establish that the service was renamed X in 2023 and is operated by X Corp. “Twitter” remains widely used informally and appears in legacy legal names, trademarks, and “formerly Twitter” descriptions, but those remnants do not make it the platform's current official name.
Caveats
- Widespread informal use of “Twitter” should not be confused with official branding.
- Legacy corporate names and retained TWITTER trademarks do not determine the platform's current name.
- The platform brand and the legal name of its operating company are distinct, though both now use X.

Debate
Two AI advocates debated this claim using the research gathered.
Argument for
Although the platform underwent a highly publicized public rebranding to "X," it officially remains Twitter in a legal and operational capacity, as evidenced by X Corp.'s continued active use of the live "TWITTER" trademarks (Source 3, Source 35). Furthermore, the platform's official provider on major app storefronts is still legally registered as "TWITTER INTERNATIONAL UNLIMITED COMPANY" (Source 22), proving that Twitter remains the platform's true official designation.
The Proponent conflates ownership and residual use of TWITTER trademarks with the platform's official name—a non sequitur—while Source 3 expressly states that the platform was rebranded to "X" in 2023. The Apple listing's provider field for TWITTER INTERNATIONAL UNLIMITED COMPANY (Source 22) identifies a legal entity, not the service's designation; that same official listing calls the service "X (formerly Twitter)," corroborated by Google Play's "Welcome to X" (Source 4).
Argument against
The platform's current official consumer-facing identities call it X: Google Play titles it “X” and says “Welcome to X” (Source 4), while Apple calls it “X (formerly Twitter)” and identifies developer X Corp. (Source 22). Court filings likewise state that Twitter, Inc. merged into X Corp. and that the platform was rebranded to X in 2023 (Sources 2 and 3), so residual Twitter trademarks or legacy references cannot establish that Twitter remains its official name.
The Opponent cherry-picks consumer-facing app titles while ignoring that X Corp. itself explicitly admitted in court filings that the "TWITTER" mark "continues to persist in many ways" and is still actively used by the company (Source 3). Furthermore, by dismissing the platform's registered legal provider, "TWITTER INTERNATIONAL UNLIMITED COMPANY" (Source 22), as a mere legacy reference, the Opponent commits a logical leap that conflates a superficial marketing rebrand with the platform's official, legally binding operational identity.
Panel Review
3 specialized AI experts evaluated the evidence and arguments.
Reviewer 1 — The Logic Examiner
The evidence overwhelmingly and consistently shows that the company legally changed its name from Twitter Inc. to X Corp. (Sources 11, 13, 18, 20) and rebranded the consumer-facing platform to X in 2023 (Sources 7-10, 15-17, 19, 21, 25-26), with app stores now titling it 'X' or 'X (formerly Twitter)' (Sources 4, 22, 33); the Proponent's argument commits a composition/division fallacy by treating residual trademark ownership and a legacy provider-entity name as proof that 'Twitter' remains the official platform name, when the direct evidence (legal filings, corporate name changes, app store listings) shows the opposite. The claim that the platform is 'still officially called Twitter rather than X' does not follow logically from the evidence—if anything the evidence directly refutes it, since even the residual trademark holder is X Corp. and the platform itself is officially branded and legally operated as X.
Reviewer 2 — The Source Auditor
The most reliable sources—court filings (Sources 2–3), major outlets including Reuters, BBC, AP, CNBC, CBS, CNN, and TechCrunch (Sources 7–11, 14, 19, 21), plus current app-store listings (Sources 4, 22) and Britannica (Sources 6, 31)—uniformly establish that Twitter, Inc. merged into X Corp. in 2023 and the platform was officially rebranded to X, with residual TWITTER marks and legacy entity names insufficient to keep “Twitter” as the official designation. Trustworthy evidence therefore refutes the claim that the platform is still officially called Twitter rather than X.
Reviewer 3 — The Precision Analyst
The evidence overwhelmingly shows that the platform was officially rebranded to X and its corporate entity is now X Corp (Sources 2, 3, 4, 7, 8, 9, 11, 24, 28). The claim that it is 'still officially called Twitter rather than X' is directly contradicted by the facts, despite residual trademark usage or legacy corporate entity names.
Panel summary
Authoritative court filings, current app-store listings, and reporting from Reuters, AP, BBC, and other major outlets consistently document the 2023 rebrand from Twitter to X and the merger of Twitter, Inc. into X Corp. Logical analysis shows that continued ownership or informal use of the TWITTER trademark does not establish Twitter as the platform's official name. Precision analysis finds the categorical wording directly contradicted by both official branding and current listings. Residual references to “Twitter,” including legacy entity names and “formerly Twitter” descriptors, identify the former brand rather than the current official name.
