Google wants Australian publishers to wait two more years for AdX fix

What both sides agreed to file

On 2 October 2026, Google and the US Department of Justice filed a joint 41-page proposed final judgment in the Eastern District of Virginia, following Judge Leonie Brinkema's September remedies ruling, AdExchanger reported on 5 October.^[1] Both sides confirmed the same core architecture: AdX must submit real-time bids to non-Google publisher ad servers on exactly the same terms it offers to DoubleClick for Publishers (DFP), Google's own ad-serving platform.^[2]

The DOJ's 16 September press release said the remedies require Google to integrate AdX with Prebid, the open-source header bidding wrapper used by publishers globally, and to establish a six-year monitor and technical committee to check compliance. Associate Attorney General Stanley E. Woodward Jr. said the ruling was "a significant victory for this Department's efforts to protect and restore competition."^[2] Preferential bidding by Google Ads into AdX, and first-look or last-look advantages inside DFP, are both prohibited under the agreed terms.

Four disputes still before Brinkema

Agreement on architecture did not produce agreement on everything. Four contested questions go back to Brinkema, with the integration timeline the sharpest of them. The DOJ's proposed judgment requires Google to build the Prebid application programming interface (API), the technical connection through which rival bids flow, within 180 calendar days of the order taking effect.^[3] Google's competing proposal sets the same deadline at 12 months from the effective date.^[4]

The other open disputes cover monitoring scope, compliance processes and, most consequentially for publishers outside the United States, whether the remedies apply globally from day one or only after a 24-month grace period.

The Australian read: 24 months is the number to watch

Google holds close to 90 per cent of the publisher ad-server market, according to Julia Edwards, director of programmatic sales at Nine, writing in Mediaweek on 6 October.^[5] That concentration means the remedies' geographic scope determines when a local publisher can realistically expect to benefit. If Brinkema grants Google's 24-month international carve-out, Australian publishers sit outside the enforceable remedy framework until late 2028, nearly two years after a US publisher could begin using an open, non-discriminatory AdX connection.

Edwards put a dollar figure on what that delay costs. She wrote that "every 1% of global market share shifting to an independent player could potentially generate $50M-75M in incremental revenue".^[5] Nine's own numbers give that estimate a concrete anchor: after moving to Direct Pay Open Bidding, Edwards wrote, updated partners generated 49 per cent year-on-year revenue growth and a 41 per cent rise in impression volume.^[5]

The six-month gap between the DOJ's 180-day deadline and Google's 12-month proposal carries a direct cost for Australian publishers still waiting for the remedy to take effect. The 24-month international grace period, if granted, extends that window to four years from today.

Parallel pressure from New York

On 30 September 2026, Judge P. Kevin Castel of the US District Court for the Southern District of New York denied Google's motion for summary judgment in the publishers' class action, preserving aggregate damages estimated at US$1.72 billion through 31 March 2024, before trebling under US antitrust law, which could push maximum exposure to US$5.16 billion.^[6] That ruling, one day before the joint proposed judgment landed, adds a separate financial pressure alongside the Virginia remedies fight.

Brinkema now has two competing timelines on her desk: the DOJ's 180-day Prebid deadline and Google's 12-month alternative, along with the global-scope question that determines whether Australian publishers wait months or years. The parties filed on 2 October; the next move belongs to the court.
