Largest IPO Nears, Topping SpaceX; 2028 AI Self-Iteration Countdown

史上最大规模IPO逼近，超越SpaceX！28年AI自我迭代，智能爆炸倒计时

Xinzhiyuan says Anthropic is considering a near-$1 trillion valuation, with ARR rising to $45 billion in five months; Jack Clark predicts a greater than 50% chance that AI systems can autonomously build better versions of themselves by the end of 2028, while the article cites a 72% Kalshi probability of an IPO announcement before November 1.

Why it matters: HKR-H/K/R all pass: the hook is sharp and the post gives valuation, ARR, and 2028 odds. Source is secondary and IPO/ARR claims lack official confirmation, so it stays in 78-84.
