Tempus AI is a short idea because the stock is being pumped on recent FDA clearances for its EKG-AI tools, while the revenue from them is far off and may never materialize. x.comÂ

Tempus AI is a second- or third-tier genomic lab whose AI story is marketing mumbo jumbo, and its management team are promoters. x.comÂ
Hims & Hers' compounding direct-to-consumer distribution makes it stupidly undervalued next to Tempus AI. Hims has $2.6B in trailing revenue at a $6.7B market cap, with 66.5% annual revenue growth from Q3 2021 to Q2 2026; Tempus has $1.4B in revenue, a $14.9B market cap and 40.4% annual growth. x.comÂ
Tempus AI's selloff after it beat and raised guidance looks like a great deal, and a further drop would be a chance to buy more. x.comÂ
Tempus AI may go lower near term because of valuation, leadership reputation and insider selling, despite an amazing business. With about 25% growth expected and profitability uncertain, it is not obviously cheap. Glassdoor reviews matter in medicine's high-trust setting, and ongoing insider sales echo founder patterns that ended badly. The data piece, about 5% of market cap, can earn a high multiple, so the stock looks reasonably priced if adoption continues. x.comÂ
Tempus AI's 2025 growth was less impressive than it looks: only half was organic, with the other half coming from the Ambry acquisition. x.comÂ
Tempus AI has a data moat no one has replicated: a multimodal, patient-linked genomic, clinical and imaging dataset at scale. It holds over 8 million imaging files, 1.5 million matched clinical and molecular profiles and 4.5 million sequencing samples, which drug companies leaning on AI increasingly need. It is expanding from oncology into cardiology, neuropsychiatry and radiology. Revenue grows 25% and gross margin rose from 32% in 2021 to 64%, though last quarter's profit was a one-time item. … Show more
Tempus AI deserves a management-quality discount because of governance and credibility risk around Lefkofsky, not established medical malpractice. His history, including his Groupon tenure, how Tempus acquired Ambry, and unresolved allegations mean it should not be treated as a clean long-term compounder until cash flow, AI-derived revenue and related-party disclosures become much clearer. The stock may still trade well technically. x.comÂ
Tempus AI remains one to avoid despite an attractive chart, because the CEO's past 'malpractices' in the industry linger, which may explain how the stock has traded. x.comÂ
Tempus AI could catch a bid as a laggard in the hot medical AI space, and it could catch fire soon. Its setup is getting too hard to ignore, despite plenty of past scars on the name. x.com x.com x.comÂ
Voyager's single-molecule approach could make Nautilus the most asymmetric proteomics bet if it works. Quarterly grant revenue of about $0.2m against over $10m consumed leaves it reliant on capital; a $125m ATM risks dilution. Repeated slips make the mid-2027 launch less likely to hold; independent customer validation and a sales channel are absent. Adoption could justify billions; delay or low-price issuance could send shares below $2 again. Tempus AI remains the preferred larger holding. x.comÂ
