Musk's xAI had assured employees of $420 for their tax information. However, two months later, there has been no payment.

      Elon Musk's AI lab promised its employees a payment of $420 for providing their personal tax data to assist in training Grok before the April 15 deadline. However, two months later, Bloomberg reports that the payments have not yet been processed. Earlier this year, Musk's xAI requested its employees to submit their personal US tax returns as training data for Grok, according to internal communications cited by Bloomberg. The company offered $420 for each submission, a recurring joke from Musk that has now found its way into the tax preparation process for the AI lab. Yet, two months after collecting this data, the promised payments have yet to be made.

      The request for data coincided with the April 15 US tax deadline. By March, many Americans were already using Claude and ChatGPT for tax preparation, while xAI, as per Bloomberg, sought to launch a Grok feature capable of managing tax returns. The internal chats reviewed by Bloomberg indicated that the request was positioned to employees as a means to enhance the model with actual, complex US tax filings, which are otherwise challenging to license en masse and difficult to gather from public sources.

      Two main questions arise due to the missing payments. First, what promises regarding data handling were made associated with the initial request, considering that employee tax returns include sensitive information such as salary, dependents, addresses, financial account details, and Social Security numbers? The second question is what the unpaid funds indicate about the internal controls within a company undergoing a significant corporate restructuring.

      For context, xAI was acquired by SpaceX on February 2, 2026, in an all-stock deal that valued SpaceX at $1 trillion and xAI at $250 billion, marking the highest corporate merger valuation in history. By late March, all eleven original co-founders of xAI had departed, a near-complete exit that Bloomberg, the FT, and others have linked to internal disagreements regarding Grok’s product development and its integration with SpaceX and X. Musk has commented publicly that the company had not been properly established initially and is now being rebuilt from the ground up in what he has labeled the SpaceXAI division.

      This reconstruction context frames the $420 story. According to available reports, xAI’s restructuring has included layoffs at the team level in May, the phasing out of the xAI brand, and its integration into SpaceX’s organizational structure. A financial and controls infrastructure that relies on aligning existing payroll workflows with a new corporate parent is, based on available evidence, precisely the kind of system that could miss a small, unconventional, off-cycle payment.

      The absence of the $420 payment aligns with this pattern, and Bloomberg's framing does not suggest any intent behind it. However, the optics of the situation are significant. Musk has spent two years cultivating a public persona linked to the 4/20 joke (the $420 incentive mirrors Tesla’s famous 2018 tweet regarding a $420 share price for going private) while simultaneously leading a private company whose claimed valuation relies on rapid product development.

      During the week that Bloomberg revealed the issue of the unpaid check, xAI was reportedly trying to launch its first coding agent to compete with Anthropic and OpenAI’s Codex, while, according to accounts from the FT and Bloomberg, it was lagging behind both Claude Code and Codex in internal benchmark tests. In this context, the missing payment represents a minor operational blunder within a larger operational challenge.

      Regulatory scrutiny adds another layer to the situation. Grok is under investigation in several European jurisdictions, including a prominent French criminal inquiry into the mass generation of non-consensual sexual imagery, with which Musk has refused to cooperate, as noted by the US Department of Justice that has also opted not to assist. Any practice involving the collection of employees' personal financial records that hasn't been fulfilled with the promised compensation is likely to raise concerns among regulators monitoring the company, adding to ongoing inquiries into xAI's data handling practices.

      xAI did not respond to Bloomberg’s request for comment. While the individual payment amount is relatively small, the overall cost of compensating all employees who submitted their tax data would likely be in the low six-figure range for a lab of xAI’s size. However, the significant issue is not the dollar amount of the check, but rather what the lack of payment reveals about the operational status of a company that has spent the last four months asserting that it can execute with renewed urgency.
