يصل تركيز أسهم الذكاء الاصطناعي داخل مؤشر S&P 500 إلى ذروة فقاعة الدوت كوم – وأصبح عمال مناجم البيتكوين مكشوفين الآن

The 10 largest AI stocks now make up about 41% of the S&P 500, according to a BofA Global Research chart circulated online . That puts the AI basket at the same concentration level that tech and telecom reached around the dot-com peak. The BofA chart put the Nifty Fifty at 40% in the 1970s and Japan at 44% in the late 1980s. The comparison turns a stock-market concentration warning into a stress test for a corner of crypto that has spent the past year selling investors a new identity. The market concentration is the stress trigger. Miner disclosures and mining reports supply the exposure map.

That would hurt miners whose new valuations depend on AI growth, while possibly helping remaining miners if scarce infrastructure becomes easier to secure.
