3 keys to success every Citadel intern learns their first week on the job
Interns of Ken Griffin's $62 billion hedge fund, Citadel, will travel to Fort Lauderdale on Monday for the start of their 11-week summer program.
The 2025 class is the most exclusive yet — 0.4% of the 108,000 applicants were extended an invitation to the program across both Citadel and its market-making sister firm Citadel Securities.
This year's class is full of high-achieving brainiacs — about 80% study computer science and mathematics at schools like MIT, Stanford, Cambridge, Princeton, and Harvard. More than a dozen were USA Computing Olympiad Platinum division participants, and dozens more were medalists at the International Olympiad in Math, Physics, and Informatics.
Yet, not everyone will end the summer with a full-time job offer — the ultimate goal of the internship for many students.
As part of our exclusive look into this year's class, Business Insider spoke to Matt Mitro, the head of campus recruiting for Citadel, about how an intern stand out at such a large hedge fund.
He told BI about a few keys to success that will be drilled into the interns in their first week on the job, including learning to be "commercial" and collaboration.
Mitro's keys to a successful internship
Mitro said the first week is vital for orienting students and explaining what's ahead. They will participate in workshops, team-building exercises, and social activities — and hear from senior leaders and external speakers.
They will also learn what it will take to succeed, including the hedge fund's focus on being "commercial."
What does that mean? Mitro said it involves interns "understanding how their work applies in markets and also whether an idea they have can be put to use in a timely manner."
Meaningful and effective collaboration is another "critical feature" of Citadel's culture and a characteristic the hedge fund is looking for in would-be hires, he said.
"Some students may be used to working by themselves or in very small groups, but here, you rely on your teammates every single day," said Mitro. "We are constantly working within and across teams, and it's important to feel comfortable talking with others, relying on them, and asking questions. We're all available to each other."
Mitro added that interns should try to be self-aware and reflective of where they can grow. Even at this level, they won't be perfect.
"It's important for them to be very aware of their own developmental areas," Mitro said. "That could be communication or collaboration — how do I work with my colleagues? That commitment to self-awareness and continuous improvement is important."

Musk Follows Harvard In Biting The Hand That Feeds
Elon Musk and Harvard Both Bite the Governmental Hand that Feeds Them From an early age, children are taught essential lessons: do not play with fire, do not pet strange dogs, and if one cannot swim, stay out of the deep end. Another timeless rule—often forgotten by those in positions of immense wealth and influence—is this: do not bite the hand that feeds you. This lesson, while simple, has profound implications in the real world. It applies just as readily to billionaires and institutions as it does to children on a playground. Yet recent actions by both Elon Musk and prominent academic institutions—most notably Harvard, but also Columbia, MIT, and others—suggest that even the most successful individuals and organizations are capable of ignoring foundational wisdom. Harvard set the tone. Amid growing political scrutiny and a shifting cultural landscape, the university has drawn intense criticism over its handling of campus protests, particularly those involving slogans such as 'from the river to the sea.' The administration's decision to defend even the most controversial speech—widely viewed by many as antisemitic—has triggered investigations and jeopardized billions in tax-exempt status and government research funding. This raises a critical question: is this truly the hill worth dying on? Is preserving the right to controversial protest slogans worth risking Harvard's institutional future? It is doubtful that most students and faculty would knowingly trade funding, grants, and prestige for this fight. Elon Musk, the world's richest man, has now followed suit—this time turning his attention toward President Donald Trump, with whom he has launched a high-profile and personal feud. What makes this move especially striking is that President Trump is not a distant figure or a fading influence. He is once again sitting in the White House, wielding executive authority over regulatory agencies, defense contracting, and infrastructure initiatives—all areas that directly affect Musk's companies. Tesla, SpaceX, and xAI have flourished in part because of government partnership. SpaceX alone holds multibillion-dollar contracts with NASA and the Department of Defense. Tesla has benefitted from years of energy subsidies and EV tax incentives. Picking a fight with the sitting president—regardless of personal conviction—puts this entire ecosystem at risk. And again the question must be asked: is this battle worth the damage? Whatever principle Musk may be defending, the consequences extend far beyond himself. Shareholders, employees, and retail investors—many of whom placed their trust and savings in his leadership—are the ones left exposed. The parallel between Harvard and Musk is striking: both have been immensely successful, aided in large part by government funding, favorable regulation, and public goodwill. And both have, for different reasons, chosen to confront the very institutions and leaders that have helped sustain their growth. There is precedent for how this ends. Jack Ma, once the most powerful entrepreneur in China, famously criticized the Chinese government. The backlash was immediate and absolute. His companies were dismantled. His IPO was cancelled. His wealth and influence evaporated almost overnight. Even in less authoritarian systems, the lesson holds: those who antagonize the systems that support them may not survive the consequences. While Musk's personal net worth has dropped from nearly $450 billion to approximately $300 billion, the impact is more symbolic than practical for him. But for millions of investors, employees, and stakeholders, these battles matter. Market volatility, regulatory backlash, and reputational risk all come with tangible financial costs—costs borne not just by Musk himself, but by those who have trusted and invested in his vision. The same applies to Harvard and peer institutions. Their leadership may believe they are standing on principle, but the price of alienating government agencies and key financial backers could reshape the long-term trajectory of these universities. The erosion of public trust, the loss of bipartisan support, and the potential withdrawal of federal funding pose existential threats. Leadership—whether in business or academia—requires more than conviction. It requires judgment, timing, and the discipline to separate personal ideology from institutional responsibility. Founder-led companies often outperform when leaders are focused, visionary, and measured. But when ego replaces strategy, the consequences can be swift and severe. No one is demanding absolute political alignment or silence in the face of controversy. No one is asking Elon Musk to wear a MAGA hat. But his recent actions have been so volatile, so self-destructive, that investors may soon be tempted to hand him something else entirely—a MEGA hat: Make Elon Great Again. In today's polarized environment, the margin for error has narrowed. And for those who owe much of their success to public support—whether in Silicon Valley or the Ivy League—biting the hand that feeds is not just unwise. It is unsustainable. ---------------------------------- Disclosure: Past performance is no guarantee of future results.

Prosthetics Startups' Biggest Market Isn't Humans. They're Building Hands For Robots Instead.
Aadeel Akhtar, the founder of Psyonic, has a PhD from the University of Illinois Urbana-Champain. Matt Carney was good at building robots — he just didn't want to. While earning his PhD at MIT, he'd spent years studying mechanical engineering and biomechatronics in service of developing bionic prosthetics that could help people who'd lost limbs. He hoped to build robotic legs that could pick up on the phantom signals sent by a body's muscles or function autonomously so it could move naturally, unlike the plastic, unmoving prostheses that are common now. But as he began talking to venture capitalists about funding a company that would develop these so-called bionics, he quickly discovered that the market didn't want robotic devices that could replace human limbs, it wanted robots that could replace human beings, the sort of humanoids championed by sci fi laureates like Isaac Asimov and self-appointed tech visionaries like Elon Musk. Investors cautioned him against venturing into the cost-heavy medical world and regularly asked if he might be more interested in building humanoids or exoskeleton suits. Even trusted experts building bionic limbs told him the technology currently available wasn't advanced enough to be truly helpful. Without a breakthrough in AI, let alone an addressable market, building futuristic robot body parts wasn't something investors would bankroll. So Carney looked elsewhere, taking a job as chief engineer at Persona AI, an early-stage contender in the field of humanoid robotics that has raised $27 million in funding. It's facing off against much larger startups like Boston Dynamics, Foundation Robotics and Figure AI, which have achieved valuations greater than $1 billion for their human-like bots. Then there's the elephant in the room: Musk's Tesla, which the world's richest man has pivoted toward building humanoid robots, with the idea that they'll generate trillions in revenue for the company and someday outnumber humans. Musk has touted a lofty vision of the future where he sees these robots as a catch-all method for labor, posting on X about replacing surgeons, being a 'personal C-3PO or R2-D2' to perform the bidding of an owner, and, of course, driving a car. Much of the tech world seems sold on them, too. The Information reported Wednesday that Amazon will begin testing out package delivery with humanoids. Speaking onstage at an event in late May for the Ronald Reagan Presidential Foundation and Institute, billionaire venture capitalist Marc Andreessen said that humanoid robotics provide a solution to regaining manufacturing dominance in the United States, with these robots performing tedious tasks such as installing screws on an assembly line. Carney plans to return to the prosthetics space one day. But he isn't the only entrepreneur who originally wanted to focus on building so-called bionic limbs to help real people, and instead have been pushed to follow the money: why not build for robots too? Take San Diego-based Psyonic, which officially launched in 2021 solely as a prosthetics company, building a waterproof robotic hand with built-in sensors to register touch sensations (alongside perks like the ability to charge a cell phone). Psyonic found some early traction, with Medicare covering the cost of its hands for patients. It was last valued at $65 million in 2024 and has raised a total of $8 million, according to PitchBook. Not long after launching, CEO and founder Aadeel Akhtar started to realize that there could be an entirely new market for his startup's hands, signing on Meta as an early robotics customer for an AI project. By 2023, humanoid robotics were booming, and demand skyrocketed. Now, the majority of Psyonic's business comes from selling its hands to manufacturing firms and robotics companies like Apptronik, which has raised more than $400 million to build humanoid, general purpose robots. The robotics side of his business 'is growing exponentially right now,' Akhtar told Forbes, later adding, 'The big draw there is being able to have one generalized robot do many tasks as opposed to activity specific robots.' Shifting toward catering to humanoid robotics startups comes with advantages. The hundreds of millions being poured into the space is helping commoditize the cost of the core technologies — the actuators, sensors, control methods and carrying capabilities needed to build both humanoid robots and bionic limbs. Akhtar said the shift has helped it further develop its prosthetics technology, and lower its prices. For San Antonio-based Alt-Bionics founder and CEO Ryan Saavedra, who was inspired to build inexpensive robotic hands after his hand was injured in a rock climbing accident, Apptronik is also a major customer. Now, the company sells more robotic hands than prosthetics to 'tier one humanoid companies.' It's a form of 'cross-pollination,' Saavedra said. And Leeds, England-based COVVI, which makes prosthetic hands with the ability to move individual fingers, recently launched a robotic hand tailormade for humanoid robots. 'Every humanoid robot needs robotic arms and legs,' said Connor Glass, the CEO and founder of Phantom Neuro, which is developing a non-invasive implant that enables a person to control a prosthetic device and works closely with prosthetics companies. 'Now [startups] are able to pivot in a way, and try to generate revenue by working with these humanoid robot companies.' It looks like a savvy business move. A Goldman Sachs report from 2024 projects that the total addressable market for humanoid robots will reach $38 billion by 2035. It projects that millions of general purpose human-shaped robots will be produced by then, with a 40% reduction in costs. (Right now, they're often prohibitively expensive; Apptronik is targeting a $50,000 price tag but hasn't reached this unit price, and Boston Dynamics' Atlas robot reportedly costs hundreds of thousands of dollars.) By contrast, there are only 5.6 million U.S. citizens with limb loss or limb difference, according to the Amputee Coalition. That makes this a very small market, and one that's accessed through the U.S. healthcare system. It can take years and millions of dollars to get a more advanced product through the FDA or navigate a complicated insurance system. Robots don't have such hurdles. Not all prosthetics startups are going after this new opportunity. Joel Gibbard, who cofounded Bristol, U.K.-based Open Bionics in 2014 and has raised $18 million to date, has decided to stay focused on making its 3D-printed bionic arms for humans, not robots. 'Everyone in this space is probably having those ideas, thinking about it as a growth opportunity,' Gibbard said. 'I don't know if we've made the right judgment, but I can tell you that we've made a conscious decision.' Bionics needs a watershed moment to get investors' attention, said Tyler Hayes, founder of Atom Limbs, which is building a complex AI-powered arm. 'A company is going to need to demonstrate a pretty significant breakthrough, as the public would see it, for bionic limbs to get that kind of traction,' he said. Building robot limbs for bots is far from a sure bet. Ken Goldberg, the cofounder of robotics firms Ambi Robotics and Jacobi Robotics and a University of California-Berkeley professor, told Forbes that while advances in humanoid robotics are possible in the (very) long term, the timeline and hype surrounding them are exaggerated. Videos promoting these humanoids' capabilities are often misleading, and there's always a wizard behind the curtain, he said. 'Robots are getting very good at locomotion, walking, and so there are all these robots out there that look like humans, walk like humans, and people think 'Well then, they are humans',' he said. 'Manipulation, the hands, is where the challenge is.' (That's why his company, Ambi Robotics, is building purpose-built AI-powered robots that can grip and sort packages, while his newer startup, Jacobi Robotics, is developing purpose-built robots for moving items on and off industrial pallets.) Simple tasks like folding a box or clothes, anything that requires dexterity, are challenging and harder than an activity like walking. It's no wonder humanoid startups are looking toward bionic prosthetics for help. 'We're nowhere near being able to automate those things,' Goldberg said. 'Hands on a robot is a surprisingly big leap.'
