The xAI logo is the mark of Elon Musk’s artificial intelligence company, which he founded in March 2023 and announced publicly on July 12, 2023. It spells “xAI” in a handful of slanted black strokes, and it has a short but eventful history: in 2026 the company was bought by SpaceX and renamed twice.
The design sits among the tech company logos that avoid brain and robot imagery in favor of pure letterforms.
What is the xAI Logo?
The xAI logo is a black mark that compresses the letters x, A and I into slanted strokes. It has been in use since xAI’s public launch in July 2023, and no designer or agency has been publicly credited. In July 2026 the company moved to a merged SpaceXAI mark after SpaceX acquired it.
| Symbol | Slanted black strokes forming “xAI” |
| Designer/agency | Not publicly credited |
| Current version since | The xAI logo ran from July 2023 to July 2026; the SpaceXAI mark replaced it in July 2026 |
| Colors (hex) | Black #000000 on white #FFFFFF |
| Typeface | Custom geometric letterforms, no typeface. Grok’s 2024 wordmark reportedly used Josefin Sans, a free Google Font |
| Previous major version | None; the 2023 mark was the first xAI logo |
How Has the xAI Logo Evolved Over Time?
For three years the company mark did not change. What changed was ownership and naming: xAI acquired X Corp. in March 2025, SpaceX acquired xAI on February 2, 2026, and the brand followed in July.
xAI Logo (2023–2026)
The original mark is a black, angular wordmark. A thick diagonal makes the “x”, a second diagonal and a tapered vertical bar to its right read as “A” and “I”, and narrow white gaps separate the pieces. It was used on the xAI website and the Grok chatbot from the 2023 launch.
Grok Logo (2024–2025)
Grok’s own branding changed more often than the parent mark. Its first icon reused the xAI symbol, and 1000logos describes the May 2024 Grok-1 logo as a simple black wordmark in Josefin Sans. In February 2025 Grok switched to a black circle with a diagonal slash, designed by Jon Vio around the idea of a singularity, according to IT Home.
SpaceXAI Logo (July 2026)
On July 6, 2026 the company announced “We are now @SpaceXAI” with a video in which the xAI logo morphs into a new mark. Not a Tesla App reported that the new logo takes the swooping X and the stylized A from the SpaceX logo and sets the name in capitals as “XAI”. Fast Company and Gizmodo both criticized how hard the AI part is to read. No designer was named.
SpaceXSI (October 2026)
On October 4, 2026 Elon Musk said SpaceXAI would be renamed SpaceXSI, with “SI” standing for “Super Intelligence”, and the official X account switched to @SpaceXSI. No separate SpaceXSI logo had been reported at the time of writing, so the July 2026 SpaceXAI mark is the last confirmed new logo.
What Do the Design Elements of the xAI Logo Mean?
xAI has not published an explanation of the mark. What can be seen is a compressed spelling of the name: the “x” leads, and the “A” and “I” share slanted strokes, which is why the logo is sometimes misread as “X1”.
Why Is the xAI Logo Black and White?
The logo uses only black and white: #000000 on light backgrounds and white on dark ones. xAI has not published a palette, and the Dodger Blue accent (#2196F3) that appears in some lists has no source.
What Font Is Used in the xAI Logo?
The xAI mark is custom geometry, so there is no font to install. The Grok wordmark is a different matter: 1000logos reports that the May 2024 version used Josefin Sans by Santiago Orozco, which is a close free option for that wordmark. Later Grok wordmarks use a heavier sans-serif whose name has not been published.
How Does the xAI Logo Compare to Competitor Logos?
Among the AI logos in the image, Anthropic’s is also a black letterform mark, while Mistral AI’s pixel-style M uses warm colors and DeepMind’s wordmark pairs with a blue swirl. The xAI mark is the sharpest of the four, with no curves at all.
How Does the xAI Logo Relate to SpaceX and Tesla?
After SpaceX acquired xAI in February 2026, the AI business became a unit of the company behind the SpaceX logo, and that is why the 2026 rebrand borrowed SpaceX’s lettering. Tesla remains a separate company with its own logo.
How Should the xAI Logo Be Used?
The xAI and Grok names and logos are the company’s trademarks. Using them to identify the company in editorial work is generally accepted, but showing them in a way that suggests a partnership or endorsement requires written permission.
FAQ on the xAI Logo
What does the xAI logo look like?
The xAI logo is a black mark made of slanted strokes that read as a lowercase “x” followed by an “A” and an “I”. A thick diagonal forms the x, a second diagonal and a tapered vertical bar sit to its right, and thin white gaps separate the pieces.
Who designed the xAI logo?
No designer or agency has been publicly credited for the xAI logo. The separate Grok icon introduced in February 2025 was designed by Jon Vio, according to IT Home.
When was the xAI logo introduced?
The logo has been in use since xAI’s public launch in July 2023. The company was incorporated in Nevada on March 9, 2023, and Elon Musk announced it on July 12, 2023.
What happened to the xAI logo in 2026?
SpaceX acquired xAI on February 2, 2026. On July 6, 2026 the company renamed itself SpaceXAI and showed a new logo that mixes the xAI mark with letterforms from the SpaceX logo. In October 2026 Musk said the name would change again to SpaceXSI.
What font does the xAI logo use?
The xAI logo is built from custom geometric shapes rather than a typeface. For the Grok wordmark, 1000logos reports Josefin Sans in its May 2024 version. Later Grok wordmarks use a heavier sans-serif that has not been named.
What colors are in the xAI logo?
The xAI logo is black on white, or white on black. The usual values are #000000 and #FFFFFF. xAI has not published a color palette, and an accent blue sometimes listed online is not supported by any source.
What is the Grok logo?
As of 2025 the Grok logo is a black circle with a diagonal slash, paired with a bold uppercase “Grok” wordmark. It replaced an earlier Grok icon that reused the xAI mark. Designer Jon Vio says it is based on the idea of a singularity, like a black hole.
Is the xAI logo the same as the X (Twitter) logo?
No. The X platform uses its own stylized X. xAI acquired X Corp. in March 2025 in an all-stock deal, so the two share an owner, but their logos are different.
What does the xAI logo mean?
xAI has not published an official explanation. The shapes spell the company name in compressed form, and the slanted strokes give it a sharp, technical look.
Is the xAI logo still used?
The xAI logo ran from 2023 to 2026. After the July 2026 rebrand to SpaceXAI the company moved to a merged SpaceX-style mark, and in October 2026 it was reported to be switching to the name SpaceXSI.
Can I use the xAI logo in my project?
The xAI and Grok names and logos are trademarks of the company. Referring to the company in editorial content is generally fine, but implying a partnership or endorsement needs written permission.
Conclusion
The xAI logo is an angular black wordmark that was used unchanged from 2023 until SpaceX absorbed the company in 2026. Its replacement in July 2026 merged it with SpaceX lettering, and the October 2026 rename to SpaceXSI means the branding is still moving. Treat any claim about a designer, accent color or official guidelines with caution, since none has been published.
