Worldwide telecom capital expenditure rose 5% in the first half of 2026, according to the latest figures from analyst firm Dell'Oro Group reported by Light Reading. The increase marks a notable shift for an industry that had spent the previous years tightening budgets as 5G buildouts matured and revenue growth stayed flat.

The 5% growth figure is the hardest data point in the Dell'Oro tally, and it signals that operators are once again loosening the purse strings. For equipment vendors — Nokia, Ericsson, Huawei, ZTE and the rest of the supply base — any sustained capex expansion directly feeds order books, because operator spending on radio access networks, transport and core infrastructure drives a large share of vendor revenue.

Why does a 5% rise matter?

Context matters here. Telecom capex peaked around the height of the 5G radio rollout cycle earlier in the decade, then declined as major markets — China, the United States and much of Europe — completed their initial coverage deployments. Analysts, including Dell'Oro itself, had tracked successive down years for the mobile infrastructure market during that correction.

A 5% increase in the opening half of 2026 therefore suggests the investment cycle has turned. Operators are directing money at the next wave of network work rather than winding down the last one. What the headline figure does not yet reveal is the regional and technology split — whether the growth comes from a handful of large markets or is broad-based, and which segments, such as RAN, optical transport, or cloud-native core, are absorbing the extra spend.

What could be driving operators to spend again?

Several industry pressures fit an inflection of this kind, even though the reported figures do not break out the causes:

• Aging first-generation 5G gear approaching refresh cycles
• Rising traffic loads on both fixed and mobile networks
• The compute and transport upgrades that new AI-driven services demand
• Continued fiber expansion in markets with thin fixed coverage

Dell'Oro's own coverage of the sector has consistently framed capex as the swing variable for vendor fortunes. When operators cut, as they did after the 5G peak, vendor revenues fell with them. When operators spend, the effect flows through the supply chain within quarters.

What comes next?

The first-half number sets the baseline for the rest of 2026. If the 5% growth rate holds through the second half, the full year would represent the strongest worldwide capex expansion since the peak of the 5G investment cycle — and a clear signal that the industry's post-5G austerity period has ended. Operators' budget decisions in the coming quarters, and Dell'Oro's next update, will show whether the first-half acceleration was the start of a sustained upcycle or a one-off catch-up in spending.
