UnitedHealth runs more than 3,000 subsidiaries and moves $150 billion a year between them, and Mark Cuban, co-founder of Cost Plus Drugs, told a16z in this interview that employers who sign its benefit contracts rarely know where their money goes.
Much of the talk about AI in healthcare is about claims and billing. Mark thinks the bigger lever is an employer reading its benefits contract before it signs, and that one AI prompt now does the reading.
"If the employers representing 67%, the 160 million plus Americans, actually did one thing — ran their contracts through AI before they signed them... The cost of health care in this country would drop like a rock."
Mark built Cost Plus Drugs from 111 generic medications in January 2022 to about 4,000 products, and he has run the same contract review for the cities of Dallas, Denver and Fort Worth.

With Mark Cuban, Co-Founder of Cost Plus Drugs
Key Takeaways
Vertically integrated insurers profit from the subsidiaries they route patients to, not only from premiums
UnitedHealth has 3,000-plus subsidiaries and $150 billion in yearly intercompany transfers
One AI prompt can flag the overcharges in a benefits contract within about 30 seconds
AI only helps before the contract is signed, because after that the terms bind the employer
The AI "bot war" over claims nets out, so the bigger gain goes to patients checking their own costs
The cost of a drug designed around one patient's DNA will approach zero, starting with over-the-counter drugs
Doctors become more necessary, not less, as medicine moves to data about one person
Mark would make every contract that involves taxpayer money public, with no redactions
1. From 111 Drugs to 4,000
Cost Plus Drugs launched on January 19, 2022 with 111 generic medications. It now carries roughly 4,000 products.
A Cost Plus Drugs pharmacy card lets patients pay its prices at 17,000 local pharmacies
Each affiliated pharmacy gets a $12 fee per prescription filled. Mark set it up that way to support independent pharmacies.
Cost Plus Drugs' Dallas plant fits into 5,000 square feet what would normally need a football field
AI and robotics let the facility turn over a batch of drugs every four hours. The company also builds "pods," mobile factories about the size of a tractor trailer that cost roughly $20 million each. The government was the first customer. A pod can be set up for sterile injectables, for tablets, or for therapies made for a single patient at a research hospital.
