xAI is acquiring X. This will be one of the largest and most impactful companies in history.
@xAI has acquired @X in an all-stock transaction. The combination values xAI at $80 billion and X at $33 billion ($45B less $12B debt). Since its founding two years ago, xAI has rapidly become one of the leading AI labs in the world, building models and data centers at unprecedented speed and scale. X is the digital town square where more than 600M active users go to find the real-time source of ground truth and, in the last two years, has been transformed into one of the most efficient companies in the world, positioning it to deliver scalable future growth. xAI and X’s futures are intertwined. Today, we officially take the step to combine the data, models, compute, distribution and talent. This combination will unlock immense potential by blending xAI’s advanced AI capability and expertise with X’s massive reach. The combined company will deliver smarter, more meaningful experiences to billions of people while staying true to our core mission of seeking truth and advancing knowledge. This will allow us to build a platform that doesn’t just reflect the world but actively accelerates human progress. I would like to recognize the hardcore dedication of everyone at xAI and X that has brought us to this point. This is just the beginning. Thank you for your continued partnership and support.

Thank you, Mr. President @POTUS, for this opportunity. It will be an honor to serve my country under your leadership. I am also very grateful to @SecDuffy, who skillfully oversees @NASA alongside his many other responsibilities. The support from the space-loving community has been overwhelming. I am not sure how I earned the trust of so many, but I will do everything I can to live up to those expectations. To the innovators building the orbital economy, to the scientists pursuing breakthrough discoveries and to dreamers across the world eager for a return to the Moon and the grand journey beyond--these are the most exciting times since the dawn of the space age-- and I truly believe the future we have all been waiting for will soon become reality. And to the best and brightest at NASA, and to all the commercial and international partners, we have an extraordinary responsibility--but the clock is running. The journey is never easy, but it is time to inspire the world once again to achieve the near-impossible--to undertake and accomplish big, bold endeavors in space...and when we do, we will make life better here at home and challenge the next generation to go even further. NASA will never be a caretaker of history--but will forever make history. Godspeed, President Donald J. Trump, and Godspeed NASA, as America leads the greatest adventure in human history 🇺🇸
