ASC 842 Is About To Drop A Bomb On AI Hype

AI hyperscalers like Microsoft, Meta, Amazon, and Alphabet face a looming liability surge as ASC 842 lease accounting rules hit. ASC 842 will force recognition of long-term lease obligations on balance sheets, materially increasing reported leverage and altering financial optics. Current GAAP accounting timing mismatches—especially for capex and lease expenses—have overstated AI sector profitability and masked true cash outflows. As lease and purchase commitments become recognized, AI companies’ earnings growth faces significant headwinds, and current high valuations appear increasingly suspect.

In December 2018, a seemingly small change to standard accounting sent shockwaves through retailers and office users. The aftershock clipped REITs as tenants across most property sectors were no longer willing to sign very long leases. In 2026, this same accounting change is about to send a similar shockwave through AI. Trillions of dollars of lease obligations that are currently under the radar are about to show up as liabilities on the balance sheets of hyperscalers and other AI purveyors. All of this is due to ASC 842. This article will dig into the subtleties of accounting rule ASC 842 and discuss its implications for the balance sheets of major AI players.

What is ASC 842?

In December of 2018, the Financial Accounting Standards Board (FASB) replaced ASC 840 with ASC 842. Under the former rule, lease obligations could be held off-balance sheet, but under 842, lease obligations were to be recorded as liabilities. The magnitude of this change becomes clear when considering something like a 20-year lease in which the present value of the full 20 years of rent payments now shows up as a liability. Imagine the percentage of Americans that would have negative net worth if creditors were to treat the present value of the next 20 years of apartment rent as a debt. Apartment leases are generally 1 year long, so this doesn’t happen, but it was common for retail and office to have 20-year leases.

As this was implemented, retailers with previously decent balance sheets suddenly had high leverage. Take a look at Kohl’s Corporation's (KSS) balance sheet before and after ASC 842. It seems there was a grace period such that ASC 842 was not in the February 2019 numbers but is in the 2020 numbers. KSS Kohl’s already had many long-term leases, but the $2.6B operating lease liability is a new figure on the balance sheet for the 2020 column. For a company with only $1.86B in long-term debt, an extra liability line item of $2.6B really changes the profile. There is an offsetting operating lease asset recorded ($2.39B in Kohl’s screenshot above), so it doesn’t have a major effect with regard to shareholder equity. However, liabilities as a percentage of the balance sheet are substantially higher post-ASC 842. Over time, it seems to have changed perceptions of the balance sheets of retailers and office users. Prior to ASC 842, 20-year leases were quite common across multiple real estate asset types. The duration of new leases has since shortened to more like 5-10 years. I suspect this is to reduce the size of that liability line item. REITs felt the burden of this change in appetite for long leases. Leases now have to be renewed significantly more often, and a lower weighted average lease term reduces visibility of future cash flows. I believe this was a material contributor to REIT underperformance in the 2019-2025 timeframe.

AI is about to get hit with over $2.4 trillion of liabilities

One of the subtleties of ASC 842 is that leases only have to be recorded as liabilities once the leases commence. A signed lease is not yet shown as a liability until the actual commencement of rent, and due to the rapidity of AI buil...
