TL;DR: Invalid traffic and ad fraud are persistent problems in US programmatic advertising. Agentic advertising platforms need to address IVT not only at the impression level but at the deal governance level, where agent-negotiated terms can be manipulated if the fraud surface is not understood.

The IVT Problem in US Programmatic

Invalid traffic (IVT) refers to advertising impressions that are not generated by real human users. It includes bot traffic, click farms, domain spoofing, and other techniques designed to generate fraudulent ad revenue. The Association of National Advertisers has repeatedly documented the scale of IVT in US programmatic, with estimates of wasted spend running into billions of dollars annually.

US programmatic buyers address IVT through a combination of pre-bid filtering (blocking known bad inventory before bidding), post-bid verification (measuring IVT rates in delivered campaigns), and vendor accreditation (requiring IVT measurement from MRC-accredited vendors).

How Agentic Advertising Changes the Fraud Surface

Agentic advertising introduces additional considerations for IVT and fraud that do not arise in conventional auction-based programmatic.

In an auction-based model, fraud typically operates at the impression level: fraudulent inventory is placed into the supply chain, wins bids, and generates fraudulent delivery data. In a negotiated, agentic model, the fraud surface includes the deal negotiation itself.

A sell-side agent acting in bad faith, or operating on behalf of a publisher with fraudulent inventory, could negotiate deal terms that appear legitimate in the deal record but execute against invalid inventory. The bilateral deal record documents what was agreed; it does not automatically verify that what was delivered was valid.

This means that IVT verification remains a necessary layer in agentic advertising, even where the deal governance layer is transparent. The deal record and the measurement record are distinct, and independent IVT verification is required to connect them.

What Buyers Should Require

US buyers deploying agentic advertising should treat IVT requirements as part of the mandate definition process.

The agent mandate should specify that only inventory verified by an MRC-accredited IVT measurement vendor is eligible for deal negotiation.

The deal record should include the IVT measurement vendor as a parameter, so that the seller's infrastructure knows what verification requirements apply.

Post-campaign, the IVT measurement report should be reconciled against the deal record to confirm that delivery was valid against the agreed terms.

Alkimi's Approach

Alkimi operates as neutral infrastructure for deal negotiation and governance. It does not replace third-party IVT measurement vendors. The DealSheet can document IVT measurement requirements as part of the agreed deal parameters, which gives buyers a record of what verification standards were in place for each negotiated deal.

For US buyers, the right model is to treat agentic deal governance and independent IVT verification as complementary requirements. Deal transparency tells buyers what was agreed. IVT measurement tells them what was delivered validly. Both are necessary.
