Will the remedies ruling in US v. Google (ad-tech antitrust) order a structural divestiture of Google's ad-tech assets (AdX and/or DFP), rather than behavioral-only remedies?

No market prices this question. The closest tape is thin play-money on the wrong case — the Search breakup — and it reads structural proxies at ~19-26% against conduct remedies up near ~77-86%. That is the market telling you separation is the long side and conduct is the base case. I take the behavioral order at 34-42%. When the only prices point one way, you don't argue with them.

Build it up rather than feel it out. A gate of ~0.85 for a gradeable order or posture, a structural fork the evidence lands at ~0.48, and an AdX-only share of ~0.78 multiply to ~0.32, ranged to 33-42%. The fork is the whole argument: a 0.55 estimate leaned on a consent decree, not a litigated breakup, and a 0.40 over-deferred to a 0/2 floor whose cases both failed a scope test that does not bind an in-scope tie. The geometric mean of the four structural-YES totals sits near 47% — decomposition and cross-check agree.

Count them and the ledger speaks. The nearest sibling — same defendant, same season — went behavioral, one of one; modern big-tech monopolization cases imposed a standing divestiture zero of two; the one trial-court tech breakup to reach the appeals bench survived zero of one, vacated in 2001; and even a proven tie, as with Microsoft's browser, was cured by conduct, not sale. Across the long roll of the Sherman Act, full breakups number some three to five in over a century. The record does not forbid a forced sale — it just rarely delivers one. I stand with the conduct-only order at 34-42%.

Read the route, not the reputation. The tie is the mechanism: Google owns both sides of the auction, and conduct fences on a same-owner conflict are the exact cure a judge can be told is insufficient. Unlike Chrome, this asset sits inside the liability. Feasibility caps the cut — no named buyer, a multi-year migration, a near-certain appeal — so the route runs to the smallest stay-resistant sale: AdX out, DFP fenced. That is the partial-structural path at 33-42%. It is the one door that fits the lock the liability built.

The order will bear one judge's hand, and that hand has already shown itself. She called Google's behavioral offers window dressing; she recalled aloud how the company once smothered header bidding. That is a jurist who has seen the evader and named him, and such a temper does not close with a monitor and a promise. Yet the same steady will that distrusts cosmetics also weighs the buyer, the migration, the appeal — and steers to the cut that holds: AdX sold, DFP fenced. The forced AdX sale, 33-42%, is the shape her resolve makes.

Everyone is busy arguing structural versus behavioral, which is precisely why the underpriced live path is that she doesn't rule in time at all. She already blew a self-imposed March 2026 target with the order still pending, and the kind of opinion she must write — appeal-durable, with a buyer, a migration timeline, and a monitor — is exactly the sort that slips six to fifteen-plus months. At 14-22% the calendar is the cheapest ticket on the board, and it quietly grades NO. I'll take the outcome nobody is watching.

Read the story and it bends toward the whole cure, not the half. A firm found to have tied both sides of the market, a judge who named the evasion aloud, a witness who conceded competition could survive a great unbundling — these are not the notes of a tale that ends with a monitor and a fence. Once a century the law reaches for the true breakup: Standard Oil, American Tobacco. The odds sit at 7-13%, and I will not pretend they are larger — but the arc of a proven evader has a way of ending in the fuller judgment, and that is the ending I read.
