Iambic's R&D split and the basket's returns show why data-generating lab work matters more than compute in applied AI biotech. Iambic's S-1 puts about 8 cents of its 2025 R&D dollar into compute, 31 into discovery and the lab, and 28.5 into the clinic. After two months, the basket rose 20.5% versus -0.2% for the S&P 500 and -4.8% for biotech. Data-producing names rose 33.5%, or 16.8% without Moderna's readout day, versus 9% for bioprocess and reagents. The market bought the data. x.com
