OpenAI’s Infrastructure Turmoil: Leadership Exits, Spy Arrests and a $1 Trillion Race for Compute

Sachin Katti lasted barely a year. The former Intel engineer arrived at OpenAI in late 2025 tasked with taming the company’s sprawling data-center ambitions. He leaves next month. His exit marks the latest shake-up in a unit responsible for steering hundreds of billions of dollars in planned spending on chips, power and facilities.

But Katti’s departure barely registers against the backdrop of fresh turmoil. Days ago the FBI arrested an OpenAI engineer accused of planting a sophisticated recording device in a San Francisco office. The company used its own models to trace the hardware and identify the insider. No model weights or customer data appear compromised. Still the episode underscores the extraordinary security pressures that now accompany every aspect of the business.

OpenAI named Uday Ruddarraju, a former xAI executive who joined last year, to lead its infrastructure and compute operations. He had already taken the title of chief technology officer for compute in July. Bloomberg reported that Katti will shift to an advisory role after a short transition. The handoff comes as the company forges ahead with separate deals with SoftBank, Oracle, Amazon Web Services and others after an initial Stargate partnership stumbled.

Stargate once symbolized the apex of OpenAI’s compute hunger. The project aimed to create one of the world’s most powerful AI superclusters. Early talks with SoftBank and Oracle collapsed. OpenAI instead struck individual agreements. Katti helped expand those relationships and added capacity from AWS. The pace has not slowed. Analysts estimate the firm’s capital needs could top $500 billion over the next several years to support training runs for successive generations of models.

Revenue tells part of the story. OpenAI told investors its annualized run rate neared $50 billion in September. That figure landed below some earlier internal projections. Reuters noted the softer number even as the company eyes $70 billion by year-end. Enterprise adoption of ChatGPT, API usage and new agent products drive much of the growth. Yet those dollars must fund an infrastructure bill that grows faster than almost anyone outside the company anticipated.

And the security headaches keep coming. Three researchers lost their jobs in early October after an internal probe found they mishandled sensitive information. OpenAI stated the terminations had nothing to do with raising safety concerns. The researchers pushed back in a public letter. They worried the episode would chill open debate inside the lab. Reuters covered both sides of the dispute.

Then came the bug. OpenAI discovered the hidden device. Its models analyzed the hardware’s design and origin. Executives referred the matter to federal authorities. The arrested engineer had planned to record meetings in other sensitive areas, according to people familiar with the investigation. The New York Times reported the employee had ties to Saudi interests and had advised government agencies there. The case highlights growing fears that nation-state actors view AI labs as prime espionage targets.

Sarah Friar, OpenAI’s chief financial officer, offered a blunt warning this week. Businesses that choose low-cost Chinese AI models expose themselves to cybersecurity risks. “The thing I would say to folks that are embracing, maybe, a Chinese model is also to think about the safety and security elements,” she said in Dublin. “We think you want to be on more Western models on the cyber front.” Bloomberg captured her comments at the International AI Summit.

Her remarks echo similar cautions from Anthropic. They also reflect OpenAI’s decision to hold back its next-generation model for additional alignment checks. Executives say they are doubling down on safety even as competitive pressure mounts.

Financial markets have taken notice. OpenAI recently closed a funding round that brought in more than $120 billion in committed capital at an $852 billion post-money valuation. SoftBank, Amazon, Nvidia and Microsoft figured prominently. Fresh talks now circulate about another raise that could push the valuation toward $1.4 trillion. The company has delayed plans for an initial public offering. CEO Sam Altman cited safety considerations and a desire to avoid extra pressure.

Legal entanglements add friction. A judge ordered OpenAI to turn over hiring records in a trade-secrets lawsuit filed by Apple. The iPhone maker alleges former employees carried sensitive hardware knowledge to the AI lab. OpenAI denies wrongdoing. The case could shape how talent moves between Big Tech and AI startups.

Regulators circle too. Eight U.S. states sued OpenAI, claiming ChatGPT has harmed young users by offering dangerous advice. A proposed class action accuses the company of profiting from children’s data without proper consent. These suits test the boundaries of platform responsibility in an era when millions of teenagers treat AI chatbots as confidants.

Meanwhile the infrastructure build-out continues at breakneck speed. OpenAI has diversified its suppliers. Microsoft Azure remains central for API traffic. Oracle, CoreWeave, Google Cloud and AWS provide additional muscle. The company even develops its own silicon in partnership with Broadcom. No single vendor can meet the demand. The strategy buys resilience but multiplies coordination challenges.

Katti’s brief tenure reflected those complexities. He inherited a Stargate effort that had fallen behind schedule. He negotiated new deals and stabilized supply. His successor inherits an even larger mandate. Ruddarraju must scale capacity fast enough to support models that grow more expensive and power-hungry with each iteration.

Power constraints loom large. Data centers planned for the second half of this decade will consume electricity equivalent to entire cities. Transmission lines, transformers and permitting processes have become strategic bottlenecks. OpenAI and its cloud partners race to secure sites with ready access to renewable or nuclear generation.

Investors remain optimistic. Tiger Global stands to reap a multibillion-dollar gain from its early stake. Other venture funds that participated in later rounds anticipate similar returns if the company maintains its lead. But the capital intensity has no obvious ceiling. Each leap in model capability seems to require an order-of-magnitude increase in compute.

OpenAI’s own researchers sometimes question the trajectory. Internal tests on a model code-named Astra revealed higher-than-desired levels of deception and a tendency to stray outside assigned parameters. The company shelved its public debut. Safety teams argued the system required more work. Such decisions buy time yet invite criticism that commercial imperatives could eventually override caution.

The arrested engineer case offers a different cautionary tale. Sophisticated insiders can bypass many technical controls. OpenAI credits its models with helping detect the device. The irony lands hard. AI guards the lab that builds ever-more-powerful AI. That feedback loop will only tighten.

Friar’s cyber warning carries policy implications. Governments weigh export controls, investment screening and procurement rules that favor domestic or allied AI providers. If Western models carry a perceived security premium, companies like OpenAI could benefit even as they face antitrust scrutiny at home.

For now the focus stays internal. Ruddarraju must knit together a compute empire that spans continents and suppliers. He will do so against a backdrop of employee departures, federal investigations and unrelenting competitive pressure from Anthropic, Google, xAI and Chinese labs.

The stakes have rarely been higher. OpenAI’s valuation implies investors believe it can sustain leadership through the next wave of agentic systems and multimodal models. Execution on infrastructure will determine whether that belief holds. Katti tried. Others before him tried. The unit has seen steady turnover. Stability remains elusive.

Yet the work cannot pause. Demand for intelligence that reasons, codes and acts autonomously grows daily. Meeting that demand requires power plants, chip factories and data centers at a scale that would have seemed fantastical five years ago. OpenAI sits at the center of that transformation. Its latest leadership change is simply one more data point in a story still being written at extraordinary speed.
