DAX US, the digital advertising exchange owned by Global, on October 1, 2026 took over dynamic ad insertion, hosting and distribution for the TWiT podcast network, with all 13 of TWiT's shows moving onto Global's Captivate platform in time for fourth-quarter sales. TWiT, which has produced technology programmes since 2005, keeps direct control of the host-read advertising embedded in its episodes, so a single network's inventory will now be sold through two separate routes.

In Short

A company called DAX US, which sells audio ads through automated software, will now drop ads into the 13 technology podcasts made by the TWiT network. The ads that TWiT's own hosts read inside each episode stay with TWiT, which means brands wanting those listeners will be dealing with two different sellers. The shows are switching to a hosting service owned by DAX's parent company so that the inserted ads can start selling in the last three months of 2026 and through 2027.

What was agreed

According to DAX US, the arrangement expands an existing relationship. Beyond acting as exclusive advertising partner across TWiT's full network, DAX US becomes the network's partner for dynamic ad insertion (DAI), host read and distribution, with distribution running through Captivate, the podcast hosting platform that Global also owns. The company said the partnership begins in October 2026 and that it will work closely with TWiT's in-house team on embedded advertising.

The release, issued from New York at 12:00 ET on October 1, does not say what the earlier relationship between the two companies covered. Nor does it give the length of the agreement, the division of revenue or a single audience figure for any TWiT show.

The firmest commitment came from TWiT itself. "Our confidence in this partnership is so strong that we're accelerating our move - all 13 TWiT shows will be hosted on Captivate in time for Q4 DAI sales - and well beyond," said Lisa Laporte, chief executive of TWiT. The fourth quarter began on the day those words were published, and neither company set a completion date for the migration.

Rob Walch, vice president of podcast relations at DAX US and Captivate, described the role in narrower terms than the headline of the release. DAX, he said, had been "chosen as the DAI and hosting partner for the TWiT network", and the company looked forward to providing TWiT with tools to support its growth. Laporte thanked Walch personally "for bringing us into the fold" and said DAX US wanted to work with TWiT's team "to build campaigns that deliver meaningful results for the brands we serve together."

Two sellers, one feed

The structure is a division of rights rather than a wholesale handover. According to DAX US, TWiT's embedded host-read advertising "remains fully under TWiT's direct purview", while DAX US runs the network's dynamic audio advertising through its programmatic marketplace. Brands and agencies negotiate directly with TWiT for embedded host-read campaigns and takeover sponsorships. For dynamically inserted audio across the network, they go to DAX US.

That distinction follows a technical line running through podcast advertising. A host read is recorded by the presenter in their own voice. When it is baked-in, it is mixed into the episode file during production and reaches everyone who downloads that file, permanently and without targeting. A dynamically inserted ad is chosen by an ad server at the moment the episode is requested, which allows targeting, replacement and an end date. Host reads can be delivered either way.

What "exclusive" covers

On this point the release is not consistent with itself. Its headline names DAX US the "exclusive advertising partner" of the network, and its opening paragraph lists host read among DAX's new responsibilities. Two paragraphs later, embedded host-read advertising is placed under TWiT's control, and brands are told they can work with TWiT directly on host-read campaigns and takeovers. Both executives quoted describe DAX's role as DAI and hosting. Neither mentions host reads.

Who, then, sells the host read? One reading reconciles the text: DAX US could handle spots that presenters record but that are inserted dynamically, while TWiT keeps the reads baked into episodes. The release does not say so. In practice, the exclusivity it describes applies to dynamic inventory, not to every advertisement heard on a TWiT programme.

Thirteen programmes and a new AI show

According to DAX US, the shows covered are This Week in Tech, Security Now, MacBreak Weekly, Windows Weekly, Intelligent Machines, Tech News Weekly, This Week in Space, Home Theater Geeks, Hands-On Tech, Hands-On Windows, Hands-On AI, Untitled Linux Show and iOS Today. TWiT describes its coverage as spanning cybersecurity, artificial intelligence, enterprise IT, operating systems, consumer technology and space.

The newest began on the day of the announcement. Hands-On AI, hosted by Mikah Sargent, debuted on Thursday, October 1, with new episodes due weekly. The programme sets out what AI tools do and walks listeners through using them in short, practical episodes, according to the release. The companies present AI as the fastest-growing category in technology and the show as a premium environment for brands seeking technically engaged audiences. The release offers no data in support of either claim.

The count also mixes old and new stock. Twelve of the 13 programmes arrive with existing episode archives; Hands-On AI starts from nothing.

Exchange and host under one owner

The deal places both ends of TWiT's dynamic advertising inside one group. DAX was created by Global, which describes itself as Europe's largest audio and outdoor company. The exchange began operating in the UK in 2014 and in the United States in 2017, with US headquarters in New York's Penn District. According to DAX US, advertisers can reach more than 100 million listeners through it across music, radio, podcasts and mobile games, with publisher brands including Deezer, LiveOne, AccuRadio, Live365 and HitsRadio.com.

That reach figure is lower than the one the company used earlier in the year. When DAX US brought DISQO's brand lift measurement to every audio campaign on January 6, 2026, it cited more than 108 million listeners. The October release does not explain the difference. In May, Basis and DAX gave political advertisers exclusive programmatic access to DAX's US audio inventory, which the companies described as spanning 60,000 or more podcasts and 350 or more terrestrial radio stations.

The exchange's name has shifted with its scope. Originally the Digital Audio Exchange, DAX was renamed the Digital Ad Exchange when it added digital out-of-home screens from February 2020.

Captivate arrived in the group by acquisition. Founded in Sheffield in 2019, it was bought by Global on December 20, 2021; Global said at the time that the platform hosted more than 14,000 podcasts. According to DAX US, Captivate now bundles hosting, distribution, IAB-certified analytics and marketing and workflow tools with monetisation options including Captivate Marketplace, programmatic ads and full DAI campaign management.

Owning both the host and the ad technology is a familiar pattern in audio. Triton Digital took over The Washington Post's complete podcast stack on November 13, 2025, covering hosting, programmatic sales and measurement. Whoever runs the ad server decides which campaign plays when a file is requested, and that control is the commercial prize.

How the inserted inventory works

Podcast advertising money attaches to one element of a show's RSS feed: the enclosure URL that points to the media file. Dynamic insertion operates at that request, stitching a different advertisement into the file each time an app asks for it. Moving TWiT's 13 feeds to Captivate is therefore the precondition for DAX selling anything. Until an episode is served from Global's infrastructure, there is no request for DAX's systems to answer.

The mechanism already dominates US podcast revenue. According to the IAB, dynamic ad insertion accounted for more than 90% of US podcast ad revenue by October 2023, roughly double its share three years earlier, while programmatic buying represented 11% of podcast revenue against 87% across other digital channels. Most dynamically inserted podcast inventory, in other words, is still sold through direct negotiation rather than through automated exchanges such as DAX.

The switch changes how delivery is counted, too. Under the final version 2.3 of IAB Tech Lab's Podcast Technical Measurement Guidelines, an ad placed in the first 25% of an episode counts as delivered once 25% of the file has downloaded, whereas a dynamically inserted ad needs all of its bytes to arrive. No ad counts inside a download that never reached one full minute. A host read baked into a TWiT episode and a spot DAX inserts into the same episode will be tallied against different thresholds.

Then there is the archive. Because insertion decides the ad at request time, older episodes can carry current campaigns, which is how Triton's arrangement with NBC Sports turned a back catalogue of sports episodes into live inventory. TWiT has two decades of episodes. Whether DAX will sell into that archive, or only into new releases, is not stated.

Timing is the other open question. Podcast infrastructure migrations typically take several months, covering hosting transfers, ad insertion set-up, historical content migration and staff training. TWiT has committed to moving 13 feeds within a quarter that started on announcement day.

The release also refers only to audio. It says nothing about video editions of TWiT's programmes, even though Apple added HTTP Live Streaming video with dynamic ad insertion to Apple Podcasts in February 2026, extending the same request-time mechanism to video episodes.

A network under commercial pressure

TWiT's founders have spoken publicly about advertising strain for several years. On December 12, 2023, Leo Laporte told listeners of This Week in Tech that the company projected a loss of about $1.1 million for the following year based on ad sales to date, according to a transcript published by Podnews. Three staff were laid off that week, and Laporte said TWiT hoped to double membership of Club TWiT, its subscription programme priced at $7 a month. He attributed the decline in podcast advertising partly to advertisers moving to platforms able to tell them more about who sees an ad, which he said open podcasting could not offer.

In July 2024, Lisa Laporte wrote on X that advertising goals were mostly being met that year but that the company could no longer afford a physical studio, which would close on August 9. Club TWiT, she wrote, had missed all of its growth goals since its creation.

Set against that record, the October deal adds automated, targetable demand to a business built on presenter-read sponsorship. Whether it answers the problem Leo Laporte described in 2023 depends on information the release withholds: audience size, the data used for targeting and the measurement attached to campaigns.

Exclusive network deals elsewhere

TWiT is one of several podcast publishers to hand advertising rights to a single outside seller over the past 18 months. Acast signed an exclusive global deal with The Athletic in April 2025 covering more than 35 sports podcasts, and in early February 2026 became the exclusive advertising and distribution partner for Slate's podcast network, adding more than 1.5 million weekly listens. Libsyn signed exclusive hosting and advertising partnerships with five podcasts. At far larger scale, SiriusXM Media became the exclusive US advertising representative for YouTube's audio inventory on April 22, 2026.

DAX US has assembled a run of exclusive supply of its own. LiveOne renewed its exclusive audio partnership with DAX US on December 18, 2025, a relationship first signed in 2015, projecting a 30% rise in programmatic audio ad revenue for 2026. On February 11, 2026, DAX US became the sales partner for Learfield's live college sports audio streams across more than 200 institutions. The Basis integration in May added political demand.

Nor is the host-read question new to the exchange. DAX has worked with Frequency since 2019, and in March 2025 the two companies partnered on Frequency's Premium Publisher Network, designed to make host-read campaigns buyable at programmatic scale. TWiT has taken the opposite route for its embedded reads and kept them in-house.

Why the split matters to buyers

Podcast budgets have been rising. US podcast advertising revenue reached $2.9 billion in 2025, a rise of 17.6%, according to the IAB and PwC. Magellan AI recorded 32% year-on-year growth in podcast ad spending in the fourth quarter of 2025, with 1,482 brands entering the channel in that quarter alone. Host reads took 46% of quarterly podcast spending in the third quarter of 2025, according to Magellan AI, and the firm's first-quarter 2026 benchmarks put host-read response at 2.45%, against 1.93% for programmatic placements.

Those numbers sharpen the commercial question inside TWiT's arrangement. The format with the higher measured response stays with TWiT's own sales team; the format with automated targeting and scale goes to DAX. An agency wanting both now places two orders with two counterparties, each with its own pricing and its own delivery counting. Does that make the network easier to buy, or harder?

DAX US argues the former. According to the company, agencies want host-read trust and programmatic flexibility in the same buy, a combination it says has been hard to find in podcasting, and the deal reaches technology-minded listeners and business decision-makers who are otherwise difficult to target. TWiT's 2027 advertising calendar opened with the announcement, as agencies settle next year's plans. Brian Conlan, president of DAX US, is due at Advertising Week New York the following week, where the company intends to argue that audio belongs alongside CTV in 2027 plans as a performance and reach line rather than a test budget.

The wider data cut both ways. Audio accounts for 31% of consumers' media time but only 9% of advertising budgets, according to AdsWizz, and audio and podcast advertising make up 9% of programmatic spend, up from 7% in 2023. A Video Advertising Bureau report in September forecast that podcasts will take 48% of US digital audio advertising by 2030, up from 42% this year. Exchanges need publishers that bring identifiable audiences. Publishers need demand beyond the presenter-read model that has, by TWiT's own past account, struggled to cover its costs.

What the release leaves open

Several details that buyers usually require before committing budget are missing. No download or listener figures are given for any of the 13 shows. The release does not name the demand-side platforms through which TWiT inventory will be reachable, or whether it will trade in open auction, private marketplace or programmatic guaranteed deals. Measurement is described only through Captivate's IAB-certified analytics, and it is unclear whether the DISQO brand lift integration DAX added in January will apply to TWiT campaigns. The revenue terms and the contract length remain private.

Timeline

Summary

Who: DAX US, the digital advertising exchange owned by Global, and the TWiT podcast network led by chief executive Lisa Laporte. Rob Walch, vice president of podcast relations at DAX US and Captivate, and Mikah Sargent, host of the new Hands-On AI programme, are named in the release.

What: DAX US becomes TWiT's exclusive advertising partner for dynamic audio and its partner for dynamic ad insertion, hosting and distribution through Global's Captivate platform. TWiT retains embedded host-read campaigns and takeover sponsorships, which brands buy from it directly. The release is inconsistent on whether DAX also has a host-read role.

When: The deal was announced on October 1, 2026, the same day Hands-On AI debuted and TWiT opened its 2027 advertising calendar. All 13 shows are due on Captivate in time for fourth-quarter 2026 DAI sales, with no completion date given.

Where: The release was issued from New York, where DAX US is headquartered. The inventory consists of TWiT's 13 technology podcasts, delivered through RSS feeds to podcast apps.

Why: According to DAX US, agencies want host-read credibility and programmatic targeting in the same buy as they set 2027 plans. For TWiT, which projected a loss of about $1.1 million in late 2023 and closed its studio in 2024, the arrangement adds automated demand to a business built on presenter-read sponsorship.
