How platform-competition intensity affects the single- vs multihoming trade-off

In the platform economy, multihoming is often seen as a virtue. Creators are told to “be everywhere,” to stream on Twitch, upload to YouTube, post on TikTok, and cross promote across channels. The more platforms, the better, or so the story goes. After all, spreading one’s content should expand reach, hedge risks, and capture the benefits of network effects.
But what if being everywhere makes creators less effective once platforms start competing fiercely for user attention? What if multihoming, instead of being a strength, becomes a liability?
That’s the surprising pattern I discovered in the YouTube–Twitch rivalry, explored in my recent article published in the Strategic Management Journal. When Twitch was still a niche platform favored primarily by hardcore gamers and posed no significant threat to YouTube, multihoming (maintaining a presence on both platforms) proved to be a highly effective strategy for content creators and their channels. Creators could tap into distinct audiences and leverage economies of scope by repurposing content across platforms. Consequently, multihoming channels produced more content and consistently outperformed their single-homing counterparts.
But this advantage faded as the two platforms converged. When Twitch and YouTube started competing for the same viewers, multihoming no longer paid off. I examined this shift through Twitch’s 2016 integration with Amazon Prime, which suddenly boosted the platform’s exposure among over 60 million Prime users.
As a result of this integration, Twitch evolved from being a niche platform catering primarily to hardcore gamers into a mainstream service appealing to a much broader audience. Following this competitive shock, multihomers decreased their content creation on both YouTube and Twitch, while single-homers ramped up their effort and gained market share.
The figure below illustrates this divergence in content creation activity between single-homing and multihoming YouTube and Twitch gaming channels in the wake of Twitch Prime.
This counterintuitive result offers a window into how complementors’ strategies can either strengthen or weaken platform ecosystems when markets become contested.
About the Research: Drawing on a panel dataset of around 2,000 YouTube and Twitch channels with over 20,000 monthly observations, I examined how content creators responded to Twitch Prime’s 2016 launch. The shock sharply increased competition for viewers. Using difference-in-differences analysis, I find that multihoming creators cut their content production by roughly 10 percent and saw steeper declines in subscribers than their single-homing peers. The same pattern held on Twitch itself: multihomers streamed less and lost followers, suggesting a fundamental shift in incentives rather than migration across platforms.
Why multihoming becomes a liability when platform rivalry increases
To understand this puzzle, I developed a simple game-theoretic model that examines the different incentives faced by single-homing and multihoming complementors. The core idea is that single-homers are more motivated to fight for their platform when threatened by a rival. Their best response to increased rivalry is to ramp up effort and content creation to make their platform more attractive. If their platform loses the “platform war,” they lose their only home.
Multihomers, however, do not face the same incentive. They have little reason to prefer one platform winning over the other, so their effort is less responsive to competitive threats.
A simple metaphor helps clarify this logic. Imagine a war between two countries. Individual soldiers are motivated to fight for two reasons: personal gains and a desire to help their country win. But this second motivation is weaker for a soldier with dual citizenship in both warring countries, similar to a multihoming complementor. This soldier lacks the patriotic incentive to see one country triumph at the other’s expense. While such an individual may perform well in peacetime, their value diminishes during conflict, when commitment to a single cause becomes critical.
Implications for platform managers
For platform owners, the findings highlight a trade-off often overlooked in governance design:
When platform competition is limited and platforms target distinct user bases, encouraging multihoming can expand reach and leverage creators’ cross-platform efficiencies.
When rivalry intensifies and platforms compete for the same audience, managers may need to reenergize single-homers, for example by offering targeted incentives or exclusive partnerships that align creators’ interests with the platform’s.
The broader lesson is that openness and exclusivity are not static ideals. Platform managers should dynamically adjust their complementor strategy depending on the degree of between-platform competition. Openness promotes growth when platforms are distant; exclusivity preserves commitment when they collide.
Implications for complementors and creators
For creators, these findings offer a cautionary message. Multihoming can diversify risk and increase audience reach, but only up to a point. When rival platforms compete for the same audience, divided attention may dilute performance. Creators who commit to one platform can, paradoxically, become more visible and valuable as competition intensifies.
This dynamic resonates with today’s “creator economy” debates: should influencers spread across TikTok, Instagram, and YouTube Shorts, or focus on one? The answer depends on whether platforms are expanding into distinct niches or directly encroaching on each other’s territories.
Implications for policymakers
The findings also have implications for regulators and competition authorities. Policies promoting data portability, open-interface APIs, and cross-platform interoperability, while valuable for consumer choice, may have unintended effects on ecosystem innovation.
If stronger rivalry discourages multihoming creators from contributing high-quality content, increased openness could paradoxically reduce total creative output. Regulators aiming to foster healthy digital ecosystems should therefore consider both sides of platform competition: the benefits of lower entry barriers and the potential dampening of complementor incentives when platforms become too similar.
In short, openness without attention to incentives may not produce the innovation it intends.
Looking ahead
As digital markets evolve, rivalry between platforms is increasingly less about devices or mediums, and more about content ecosystems built around short videos, live streaming, creator effort, and user attention.
Platforms that once occupied distinct niches now overlap almost entirely. After the meteoric rise of TikTok, YouTube and Instagram introduced similar features, Shorts and Reels, to capture the same creators, viewers, and engagement loops. Instagram’s new iPad app, for instance, opens directly to Reels, designed to mimic TikTok’s vertical flow.
In this converging landscape, the strategic logic for platform owners and creators is changing. When multiple platforms chase the same users and adopt similar business models, the competitive stakes escalate. My findings suggest that in these moments of convergence, when platforms essentially become clones of one another, deep commitment to one platform can yield greater rewards than spreading effort across all of them.
For platform strategists, the key question is no longer only how many creators they onboard, but how their incentives and loyalties evolve as competitors start to look and behave alike.
For creators, this means that in an attention economy crowded with identical options, focus can sometimes be a better strategy than “being everywhere.”
