美国股市触及互联网泡沫峰值警报水平——比特币矿工因人工智能而暴露

The AI trade has become concentrated enough to revive comparisons with the dot-com peak. For Bitcoin miners that have spent the past year selling investors on AI and HPC growth, that concentration is now a balance-sheet risk. 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. Public Bitcoin miners increasingly trade as hybrid infrastructure companies with BTC exposure. Many have signed AI or high-performance computing contracts, raised capital for denser data centers, converted premium power sites, or shifted investor attention toward long-term lease economics. If the AI infrastructure premium fades, those companies face a different kind of pressure. The risk moves from hashprice alone into debt, contract durability, construction execution, and equity multiples. At the same time, Bitcoin gets a second-order test. A weaker AI buildout could ease the scramble for power, rack space, interconnections, cooling equipment, and GPUs. That would hurt miners whose new valuations depend on AI growth, while possibly helping remaining miners if scarce infrastructure becomes easier to secure.
