OPENAI IS PAYING EMPLOYEES MORE THAN ANY MAJOR TECH STARTUP IN HISTORY

OpenAI's average stock-based compensation for its roughly 4,000 employees is about $1.5 million per employee. The company's equity awards, aimed at helping it keep its lead in the AI race, are inflating its heavy operating losses and diluting existing shareholders. OpenAI recently announced the discontinuation of a policy that required employees to work at the company for at least six months before their equity vests. This could lead to further compensation increases.

Metal prices have risen in recent months as China has restricted exports in response to US tariffs. It will be difficult for local startups to compete as China's grip on the industry is tight, and it is known to sell rare-earth metals for less than it costs to produce them. The biggest question is whether the US government will continue to subsidize the domestic industry, and at what level.

SOFTWARE ENGINEERING IN 2026

The primary impact of AI tooling so far is that the marginal cost of producing code has gone down significantly. However, producing code is only part of the job, so the bottlenecks for engineering time will shift elsewhere.
