When platforms become infrastructure, the governance question shifts from market competition to public utility.
The Infrastructure Threshold
Platforms cross the infrastructure threshold when the cost of not using them exceeds the cost of the terms they impose. Before that threshold, users have genuine choice: they can decline a platform's terms and operate on alternatives without significant loss. After it, the choice is nominal — the alternatives have been foreclosed by network effects, by the migration of counterparties onto the dominant platform, or by the integration of the platform's services into operational processes that cannot easily be restructured. The platform has become infrastructure in the economic sense that matters: something you cannot practically function without.
The governance implications of this threshold shift are substantial. Markets can govern optional services through competition — users who find one provider's terms unacceptable can switch to another, and this switching threat disciplines provider behaviour. Markets cannot govern infrastructure through competition alone, because the infrastructure threshold is defined by the absence of credible alternatives. Once a platform has crossed into infrastructure, the competitive discipline that would otherwise govern its terms no longer operates.
The Infrastructure Governance Gap
The infrastructure governance gap is the space between what infrastructure requires — reliable, non-discriminatory access on terms that do not extract monopoly rents from the users who depend on it — and what private platform ownership, motivated by shareholder returns rather than public utility, is structured to provide. Physical infrastructure networks — water, electricity, telecommunications — crossed this threshold in prior centuries and were eventually subjected to regulatory frameworks designed to close the governance gap. Digital platforms have crossed the threshold more recently, more rapidly, and in forms that the existing regulatory frameworks were not designed to address.
The gap produces specific and predictable harms: the arbitrary terms changes that users cannot reject because exit costs are prohibitive, the preferential treatment of the platform's own services in contexts where the platform also operates the marketplace, and the data extraction that users cannot prevent because the platform's value proposition depends on it. Each of these harms is a direct consequence of the infrastructure governance gap — of the absence of the regulatory framework that infrastructure dependence requires.
The platform that has become infrastructure has acquired a form of power that market competition cannot constrain. The question is not whether to govern it — it will be governed, by the platform itself if not by public authority — but whether the governance serves the users who depend on it or the shareholders who own it.
