Jane Street is often seen as the gold standard in trading top infra, top talent, massive volume. But they’ve been tied to questionable practices (e.g., alleged market manipulation in India, early SBF connections), and their business model is arguably just high-frequency rent-seeking.
Yet in quant circles, they rarely face pushback. Why is that? Is it just respect for execution, or are we overlooking real ethical concerns in favor of performance? Curious what others here think.
