Microsoft Advertising this month updated its pilot program policies to allow cryptocurrency exchanges to run ads across the Microsoft Audience Network in all markets where the company accepts cryptocurrency advertising - a notable shift from a position that had, since May 2022, confined crypto exchange campaigns strictly to search inventory.

A policy boundary that held for four years

When Microsoft first opened its search platform to cryptocurrency exchanges in May 2022, the boundary was explicit. Advertising for cryptocurrency exchanges remained prohibited in Microsoft Audience Network display and native advertising. The company restricted crypto exchange campaigns to pre-approved advertisers who qualified specifically for search placements, while the broader Microsoft Audience Network - encompassing display and native placements across MSN, Outlook, and connected Microsoft properties - remained off-limits to the sector entirely.

That boundary has now been lifted. According to Microsoft's May 2026 Pilot Program Policies update, Audience Ads for cryptocurrency exchanges are now allowed in all markets where Microsoft accepts cryptocurrency advertising. Advertisers must comply with all applicable Cryptocurrency and Related Products policies.

The change is published in the Microsoft Advertising Policies Change Log under the May 2026 section, covering the global scope of the pilot program. It sits alongside four other policy updates issued by Microsoft this month: a gambling expansion in Belgium and Taiwan, a predictions markets pilot in select US states, and this global Audience Ads change for cryptocurrency exchanges.

What the Audience Network is, and why it matters

The Microsoft Audience Network is the display and native arm of Microsoft's advertising business. It delivers ads across properties including MSN, Microsoft Start, Outlook.com, and Microsoft Edge, as well as a range of third-party publisher inventory that Microsoft sources programmatically. Unlike search campaigns, which reach users who have actively queried a keyword, Audience Network placements are served based on audience targeting signals - interest data, behavioral profiles, and contextual relevance derived from Microsoft's user graph.

For cryptocurrency exchanges, access to this surface represents a meaningful expansion. Search campaigns, while effective for capturing demand from people already searching for specific products, are limited to moments of declared intent. Audience ads allow campaigns to reach potential customers earlier in the decision cycle, at scale, and across content environments that carry contextual weight - financial news pages on MSN, for instance, or Outlook inboxes of users profiled as financially active. That shift from reactive to prospective reach is the fundamental difference between search and audience-based inventory.

The global scope of the change also matters. Microsoft's cryptocurrency exchange advertising has been expanding progressively by market since 2022. According to the change log, in January 2026 alone, Microsoft extended search eligibility for cryptocurrency exchanges to 27 European markets: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czechia, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, and the United Kingdom. Before that, in April 2025, India and Japan were added to the search eligibility list, following a February 2025 expansion that covered Austria, Estonia, Finland, France, Germany, Ireland, Netherlands, and Spain. Canada, New Zealand, and Switzerland had gained search eligibility in December 2024.

The May 2026 Audience Ads expansion does not enumerate specific markets. Instead, it ties access to all markets where Microsoft currently accepts cryptocurrency advertising - meaning the expanding market list for search effectively governs which markets benefit from the Audience Ads change too.

Technical requirements that remain in place

Opening the Audience Network to cryptocurrency exchange ads does not mean the sector gains unrestricted access. The pilot program policies document sets out specific program requirements that apply to all cryptocurrency advertising on Microsoft's platforms, whether through search or audience placements.

Advertisers must comply with all regulations and licensing requirements for the specific locations where their ads will be served. That includes any mandatory disclaimers, risk warnings, and labeling requirements that a given jurisdiction imposes. Where regulations or licensing requirements cannot be met for a specific state or country, the advertiser is required to exclude that location from targeting - a targeting exclusion obligation that sits with the advertiser, not Microsoft.

A structural constraint also applies: only first-party brand owners are eligible. Affiliate advertisers are not allowed. If promotions are mentioned in an ad, the advertiser must disclose any related terms and conditions on the landing page. In markets where the products being offered or traded are classified as a security, advertisers must comply with all regulatory and disclaimer requirements that flow from that classification.

Advertisers must clearly disclose the risks of investing in virtual currencies - either in the ad itself or on the landing page - and cannot represent such investments as safe or risk-free. Microsoft also requires the use of a unique Manager Account (CID) exclusively for cryptocurrency-related ads. Mixing disallowed or non-cryptocurrency content into that account can result in permission to serve crypto ads being revoked.

Advertisers seeking to participate must submit a Cryptocurrency Advertising Program Participation Form. The process involves pre-approval and is not self-serve. That requirement aligns with how Microsoft has handled other regulated categories - pharmacy and healthcare, for example, moved to a mandatory pre-approval process in January 2026 for online pharmacies and prescription drug advertisers.

For cryptocurrency wallet advertisers - a separate category from exchanges - the pilot remains more restricted, with country-level criteria still applying individually. In India, custodial wallet services must be registered with the Financial Intelligence Unit - India (FIU-IND). The Advertising Standards Council of India requires a specific disclaimer: "Crypto products and NFTs are unregulated and can be highly risky. There may be no regulatory recourse for any loss from such transactions." India and Japan gained wallet eligibility in December 2025; this month's update applies only to exchanges, not wallets.

Predictions markets pilot adds another federally regulated category

Alongside the crypto Audience Ads change, Microsoft's May 2026 policy update introduces a predictions markets pilot for the United States. This is a carefully circumscribed program tied to federal regulatory authorization, and it mirrors language that first appeared in Google's own predictions market policy in January 2026.

According to Microsoft's Pilot Programs Policies document, eligible advertisers must be authorized by the Commodity Futures Trading Commission (CFTC) as a Designated Contract Market (DCM) whose primary business must be the listing of Exchange Listed Event Contracts - or the advertiser must be authorized as a brokerage by the National Futures Association (NFA) to offer third-party access to products listed by such a DCM.

The eligible states for the predictions markets pilot are Alaska, California, Florida, Georgia, Kansas, Kentucky, Missouri, Nebraska, New Hampshire, New Jersey, New Mexico, Ohio, Oklahoma, Texas, Virginia, West Virginia, and Wyoming - 17 states in total. Self-serve access is not referenced in the pilot document for predictions markets, and applicants must use the Predictions Market Application form to be considered.

Content restrictions within the pilot are explicit and go beyond standard advertising policy boundaries. Prediction market ads may not promote or monetize subject matter that Microsoft Advertising does not otherwise permit. The policy specifically names election outcomes, geopolitical conflicts, and natural disasters as prohibited topics. Ads must not promote or facilitate predictions about outcomes involving the death, serious harm, loss of liberty, or loss of fundamental rights of an identified or identifiable individual. That last clause is precise: it targets prediction markets for outcomes tied to specific named people, not general event categories.

Google Ads opened prediction market advertising starting January 21, 2026, exclusively for platforms authorized by CFTC as Designated Contract Markets or NFA-registered brokerages. Microsoft's May 2026 pilot applies the same federal regulatory threshold as the entry criterion. Both platforms now treat CFTC authorization as the minimum standard for eligibility, establishing a de facto industry norm around federal oversight as the gateway to prediction market advertising.

Belgium opens for gambling; Taiwan allows social casinos

Two further market-level changes appear in Microsoft's May 2026 update. The Gambling and Games policy has been updated to allow ads for casinos, sports betting, and fantasy sports on Search in Belgium. And in Taiwan, the same policy now allows ads for social and sweepstakes casinos.

The Belgium change is notable given the country's historically strict gambling advertising framework. Microsoft's change log records that in July 2023, advertising for gambling became no longer allowed in Belgium at all. The May 2026 update reverses that position for Search, though eligibility criteria and pre-approval requirements for Belgian gambling advertisers would still apply under Microsoft's standard gambling policy framework, which since January 2026 has expanded its pre-approval process to all gambling and games clients globally.

For Taiwan, the change is narrower: only social casinos and sweepstakes-style games qualify, not real-money gambling. Social casinos operate without real-money wagering, allowing users to play for virtual currency or prizes that carry no cash value. The distinction matters for advertiser eligibility, as Microsoft - like Google and Meta - treats social casino advertising as a separate category from licensed gambling operations. Microsoft's January 2026 global gambling update had defined games of skill, games of chance, and social sweepstakes casinos more precisely, laying definitional groundwork that the Taiwan expansion now draws on.

The progression of Microsoft's crypto policy since 2022

The trajectory of Microsoft's cryptocurrency advertising policy since 2022 illustrates how major platforms have moved from blanket restriction toward market-by-market, category-by-category expansion. The sequence is worth tracing in full to understand where May 2026 fits.

In May 2022, Microsoft allowed pre-approved cryptocurrency exchanges into US search for the first time. Display, native, and Audience Network remained prohibited for the sector. In December 2024, Canada, New Zealand, and Switzerland were added. February 2025 brought Austria, Estonia, Finland, France, Germany, Ireland, Netherlands, and Spain. April 2025 added India and Japan. January 2026 added the remaining 27-market European list cited above, alongside a separate global expansion of the pre-approval process to all gambling and games clients.

December 2025 added two more categories: cryptocurrency wallet advertisers gained eligibility in India and Japan, and Contract for Difference (CFD) advertisers gained eligibility in Germany and the United Kingdom, each subject to country-specific regulatory compliance requirements.

May 2026 now adds the Audience Network layer globally. Every market that has been progressively unlocked for search is now also unlocked for display and native placements through the Audience Network, under the same compliance conditions. It is an additive change, not a replacement of search eligibility: exchanges that qualified for search remain qualified, and the Audience Network access is layered on top.

What this means for the marketing community

Microsoft's search advertising revenue reached $13.9 billion for fiscal year 2025, a 21% increase year-over-year. In Q3 FY26, search advertising grew 12% with the AI business at a $37 billion annual run rate. Within that context, the opening of the Audience Network to crypto exchange advertisers represents an incremental inventory expansion for Microsoft, adding a new revenue-eligible category to a network that has historically been available to financial services advertisers in other sub-categories.

For practitioners managing cryptocurrency exchange accounts, the change has immediate practical implications. Campaigns that have previously existed exclusively within the Search Network can now be extended to Audience Network placements, subject to the compliance infrastructure already required for search eligibility. The Audience Network operates on CPM-based buying rather than cost-per-click, which changes optimization logic. Audience targeting replaces keyword targeting as the primary lever - and Microsoft's audience signals, drawn from Outlook, Edge, and Microsoft account data, offer behavioral and interest profiles that search keyword data does not.

Microsoft's enhanced website exclusion tools, launched in August 2025, allow advertisers to block up to 10,000 websites per list. For cryptocurrency exchanges operating in regulated markets with strict advertising compliance requirements, that exclusion capacity is directly relevant to Audience Network campaigns: it provides the mechanism to prevent ads from appearing on content environments that could create regulatory or reputational exposure.

The compliance obligation that sits with the advertiser - rather than Microsoft - to ensure correct geo-targeting exclusions is also significant. Cryptocurrency advertising regulations vary sharply by jurisdiction. A cryptocurrency exchange authorized to advertise in Germany and the United Kingdom under CFD rules, or in France under the Autorité des marchés financiers framework, must build campaign structures that prevent delivery into markets where they are not licensed. That is not a new obligation for search campaigns, but Audience Network campaigns introduce additional complexity because display and native inventory can be purchased across a wider range of publisher environments, potentially including international traffic on domestic publisher sites.

Pilot program confidentiality rules apply. According to Microsoft's Pilot Programs Policies document, information that participants acquire, become aware of, or learn as part of their participation may not be publicly divulged or communicated to external third parties. That constraint limits what publicly available case study data will emerge from early participants.

Summary

Who: Microsoft Advertising, the advertising division of Microsoft Corporation, is the entity publishing the policy updates. Cryptocurrency exchange advertisers, licensed gambling operators in Belgium and Taiwan, and CFTC-regulated prediction market platforms in the United States are the affected advertiser categories.

What: Microsoft has expanded its Pilot Program Policies to allow cryptocurrency exchange ads to run on the Microsoft Audience Network - display and native placements - in all markets where Microsoft currently accepts cryptocurrency advertising. Separately, gambling advertising has been opened in Belgium for Search, social and sweepstakes casino ads are now permitted in Taiwan, and a predictions markets pilot has launched in 17 US states limited to CFTC-authorized Designated Contract Markets and NFA-registered brokerages.

When: The changes are recorded in Microsoft's May 2026 Advertising Policies Change Log, published in May 2026. Today is June 6, 2026.

Where: The Audience Ads cryptocurrency change is global in scope, applying to all markets where Microsoft accepts cryptocurrency advertising. The Belgium gambling expansion and Taiwan social casino change are market-specific. The predictions markets pilot covers 17 named US states: Alaska, California, Florida, Georgia, Kansas, Kentucky, Missouri, Nebraska, New Hampshire, New Jersey, New Mexico, Ohio, Oklahoma, Texas, Virginia, West Virginia, and Wyoming.

Why: Microsoft has been progressively expanding the range of regulated categories and the geographic scope of its advertising policies since 2022. The Audience Network expansion for crypto exchanges removes a structural distinction that had separated search from display and native placements for this category since May 2022. The predictions markets pilot aligns with a regulatory model that Google adopted in January 2026, applying CFTC authorization as the threshold for eligibility. The Belgium and Taiwan updates reflect local regulatory conditions that have shifted to permit certain forms of gambling or gaming advertising on Microsoft's platform.
