Africa's 2026 Sovereign Restructuring Cycle: Common Framework Outcomes, China Bilateral Geometry, and IMF Program Design
Six African sovereigns defaulted between 2020 and 2024. Zambia, Ghana, Chad, and Ethiopia have now closed Eurobond and bilateral deals. The pipeline runs through Egypt, Angola, Tunisia, Kenya, Mozambique, and Senegal, while 21 Sub Saharan countries are in active IMF programs and external debt service hits roughly USD 100 billion in 2025 and 2026.
Africa's external Eurobond stock peaked near USD 145 billion in 2021 and stood at roughly USD 140 billion at end 2024, per S&P Global Ratings. Six issuers defaulted across 2020 to 2024: Zambia, Chad, Ethiopia, Ghana, Mozambique on the Tuna Bond, and Mali on regional debt. The G20...

The African data center buildout 2026: Lagos, Nairobi, Cape Town, and Cairo
Africa hosts roughly 1.5 percent of global colocation capacity but is on track to triple installed megawatts by 2028, with Lagos, Nairobi, Cape Town, and Cairo absorbing the bulk of new builds and forcing fresh thinking on power, regulation, and inference latency.
African data center capacity is finally inflecting in 2026. Installed colocation power across the continent now sits near 700 megawatts, still a small share of the global 55 gigawatt market, but contracted pipelines suggest a path to roughly 1.8 gigawatts by 2028. South Africa, N...

The AI advertising shock: how generative search is rewiring the 700 billion dollar attention economy
Google Search ad revenue ran 198 billion dollars in 2024, a 12 percent gain that masks a structural threat. ChatGPT, Perplexity, and Claude are bleeding off the high intent query layer, AI Overviews are eroding publisher click through, and a federal judge has ruled the search monopoly illegal. The next two years rewrite the unit economics of every ad funded business on the internet.
Digital advertising sits at roughly 700 billion dollars globally, and roughly half of that pool routes through one query box at Mountain View. Alphabet reported 198 billion dollars in Google Search and other advertising revenue for 2024, up 12.5 percent year over year, with Q4 al...

Compute behind a fence: US AI export controls in 2026
Four years of BIS rules have built a tiered global compute regime. The October 2022 baseline, the October 2023 patch, the December 2024 HBM and tooling rules, and the January 2025 AI Diffusion Framework now shape every chip flow worth tracking. DeepSeek R1 forced the harder question. Are the controls working.
United States chip export controls have moved from a narrow performance ceiling into a full architecture for who gets to compute at frontier scale. The October 7, 2022 BIS rule set the first thresholds. October 17, 2023 closed the H800 and A800 workaround. December 2, 2024 added ...
