 At net prices with 48% rebates, semaglutide achieves $32,219/QALY ICER, making it highly cost-effective. The Trump Medicare deal at $245/month (82% discount) would push ICER below $30K/QALY. The inflationary claim may need scope qualification: GLP-1s are inflationary at list prices but potentially cost-saving at negotiated net prices, and the price trajectory is declining faster than the 2035 projection anticipated.

 The Trump Administration's Medicare GLP-1 deal establishes $245/month pricing (82% below list) with narrow eligibility criteria requiring comorbidities (BMI ≥27 with prediabetes/CVD or BMI >30 with heart failure/hypertension/CKD). This targets ~10% of Medicare beneficiaries—specifically the high-risk population where downstream savings (24% kidney disease progression reduction, cardiovascular protection) offset drug costs under capitation. The narrow eligibility is the mechanism that changes the cost-effectiveness calculus: inflationary impact depends on population breadth, not just drug price.

+The sarcopenic obesity mechanism creates a pathway where GLP-1s may INCREASE healthcare costs in elderly populations: muscle loss during treatment + high discontinuation (64.8% at 1 year) + preferential fat regain = sarcopenic obesity → increased fall risk, fractures, disability, and long-term care needs. This directly challenges the Medicare cost-savings thesis by creating NEW healthcare costs (disability, falls, fractures) that may offset cardiovascular and metabolic savings.

 The $50/month out-of-pocket maximum for Medicare beneficiaries (starting April 2026 for tirzepatide) removes most financial barriers to persistence for the eligible population. Lower-income patients show higher discontinuation rates, suggesting affordability drives persistence. The OOP cap may improve persistence rates specifically in Medicare, though this remains untested.

+The discontinuation problem is worse than just lost metabolic benefits - it creates a body composition trap. Patients who discontinue lose 15-40% of weight as lean mass during treatment, then regain weight preferentially as fat without muscle recovery. This means the most common outcome (discontinuation) leaves patients with WORSE body composition than baseline: same or higher fat, less muscle, higher disability risk. Weight cycling on GLP-1s is not neutral - it's actively harmful.

 Phonon Studio AI launch failed to reach its $88,888 target and entered refunding status, demonstrating that not all futarchy-governed raises succeed. The project had demonstrable traction (live product, 1000+ songs generated, functional token mechanics) but still failed to attract sufficient capital, suggesting futarchy capital formation success is not uniform across project types or market conditions.

 NFA.space launched on futard.io with $125,000 target, demonstrating futarchy-governed fundraising for physical art RWA marketplace. Project has pre-existing traction: 1,895 artists from 79 countries, 2,000+ artworks sold, $150,000 historical revenue, $5,000 MRR, 12.5% repeat purchase rate. This shows futarchy ICO platform attracting projects with demonstrated product-market fit, not just speculative launches.
