The United States posted full-year real GDP growth of 2.1% in 2025, revised down from an advance estimate of 2.2%.[BEA] That number is solid by any developed-economy standard. But the quarterly breakdown tells a more cautious story: Q3 2025 grew at 4.4%, then Q4 collapsed to 0.7% (second estimate), pulled down by falling government spending, weaker exports, and import volatility.[BEA] When you strip out government activity, real final sales to private domestic purchasers grew 2.4% in Q4 — suggesting that private-sector demand held up even as public spending contracted.

Forecasts for 2026 cluster between 1.8% and 2.5%, depending on the policy assumptions baked in. Goldman Sachs projects 2.5% growth (Q4/Q4), above the consensus of 2.1%.[Goldman Sachs] The CBO's baseline assumes the 2025 reconciliation act boosts consumer spending and private investment, with potential GDP growing 2.1% annually through 2030.[CBO] The Philadelphia Fed's survey of forecasters is more cautious at 1.8% annual average.[Philadelphia Fed] Inflation remains the complicating variable: PCE inflation held at 2.6% in 2025, core PCE at 2.8% — both above the Federal Reserve's 2% target.[BEA] Goldman Sachs expects core PCE to fall to 2.1% by December 2026, but the path depends heavily on tariff policy, which remains in flux.

The structural engine of U.S. growth in 2025 was consumer spending and private investment, particularly in AI infrastructure, clean energy, and healthcare. These three sectors are absorbing capital at a scale that is reshaping the investment landscape. The federal fiscal position adds a layer of risk: while CBO data shows revenues at 17.2% of GDP in 2025 rising to 17.5% in 2026 (above the 50-year average of 17.3%),[CBO] the deficit level itself is not directly available in current published sources — a gap noted in the data.

Five sectors dominate U.S. capital allocation in 2025–2026: artificial intelligence infrastructure, clean energy and low-carbon transition, biotechnology and genomics, digital health, and fintech. These are not merely trending — they are receiving structural capital because of policy tailwinds (the CHIPS Act, the Inflation Reduction Act), demographic demand (an ageing population driving healthcare spend), and technology step-changes (mRNA platforms, large language models, energy storage).

Low-carbon infrastructure drew $2.1 trillion globally in 2024, with the U.S. taking the largest share of developed-economy investment.[BloombergNEF] Biotechnology sits at a $1.55 trillion global market (2023 base), growing at a 13.96% CAGR through 2030,[Grand View] driven by mRNA and gene-editing commercialisation — an area where U.S. companies hold a decisive lead. Digital health hit $199.1 billion globally in 2025 and is forecast to reach $573.5 billion by 2030,[PR Newswire] with AI-driven diagnostics and remote monitoring as the growth engine. Fintech is projected to reach $882 billion globally by 2030,[Fortune BI] with U.S. payments infrastructure at its core.

The AI sector presents a more nuanced picture. Enterprise adoption is driving productivity gains across industrials, healthcare, and professional services — and the infrastructure buildout (data centres, power grid upgrades, fibre) is generating secondary investment in construction and materials. But Deloitte flags that elevated P/E ratios and high AI investment caution are moderating equity gains in 2026.[Deloitte] The gap between AI investment and AI monetisation is real. Investors are pricing in outcomes that have not yet been demonstrated at scale.

The federal corporate tax rate sits at 21% — unchanged since the 2017 Tax Cuts and Jobs Act — applied to C-corporations. LLCs, the most common structure for small and mid-size businesses, are typically taxed as pass-throughs, meaning the entity pays no federal income tax and profits flow to owners at individual rates. State corporate tax rates add a layer: New Jersey charges 11.5%, Minnesota 9.8%, while Nevada, South Dakota, and Wyoming levy no corporate income tax at all. This variation makes state selection a meaningful financial decision, not a formality.

Formation costs are low by international standards. A Delaware LLC costs $110 to file and $300 annually in franchise tax. Texas costs $308 to file and charges no annual fee. New York is an outlier — formation is $200 but requires newspaper publication of the LLC notice, costing $300 to $4,500 depending on county. The real cost of operating a business is elsewhere: monthly payroll for a single $15/hour employee costs $18–21 per hour when employer taxes and benefits are included; a small retail operation typically requires $50,000–$150,000 in upfront capital; and insurance, software, and compliance add $600–$1,000 per month at minimum.

The biggest structural challenge for businesses operating across multiple U.S. states is regulatory fragmentation. There is no single national business registration, no unified employment law, and no consistent consumer protection standard. A company operating in California, Texas, New York, and Florida is simultaneously subject to four different sets of employment regulations, data privacy laws, and industry-specific requirements. This fragmentation is not going away — if anything, state-level regulatory divergence is increasing as federal rollbacks push more governance to the state level.

Eurasia Group's top global risk for 2026 is labelled 'the U.S. political revolution' — defined as the Trump administration dismantling institutional checks on executive power and directing government machinery against perceived adversaries.[Eurasia Group] The firm describes the current U.S. administration as practising 'state capitalism with American characteristics' — the most interventionist approach since the New Deal, selectively favouring or penalising industries at a scale without modern precedent.

Harvard Law School's corporate governance researchers document the practical business consequence: direct presidential intervention in decisions about share buybacks, hiring practices, mergers, and foreign investment.[Harvard] This erodes the business judgment rule — the legal doctrine that normally protects company boards from second-guessing by outside parties. When the President of the United States publicly pressures a company to change its board-level decisions, the legal predictability that boards rely on weakens. This is a structural shift, not a one-off event.

The November 2026 midterm elections add a layer of near-term uncertainty. All 435 House seats, 33 Senate seats, and 36 governorships are up for election.[Coface] A change in House control would immediately constrain the administration's legislative agenda. The Supreme Court is expected to rule on the limits of executive tariff authority in 2026 — a decision that could either validate or significantly curtail one of the administration's most-used economic tools.[Coface] For businesses that have restructured supply chains around current tariff levels, the outcome of that ruling matters enormously.

The deregulatory agenda cuts both ways. Some sectors — financial services, energy — are benefiting from reduced compliance burdens. But the assault on Federal Reserve independence, documented by Harvard researchers,[Harvard] introduces monetary policy uncertainty that typically increases the cost of capital. Morgan Stanley notes that populist proposals like credit card interest rate caps have already dented financial sector stock prices.[Morgan Stanley] The regulatory direction is not uniformly positive or negative for business — it depends entirely on which sector you are in and which side of the political ledger you occupy.

The United States ranks third globally in the Global Innovation Index 2025, behind Switzerland and Sweden.[GII 2025] Where it leads the world: market and business sophistication (ranked first globally), gross business R&D expenditure, and corporate R&D investment. The San Jose–San Francisco cluster ranks third globally in innovation intensity and leads in Silicon Valley-driven output.[GII 2025] On AI specifically, Capital Economics' proprietary AI Economic Impact Index places the U.S. first globally on both innovation and diffusion capacity.[Capital Economics] No other country is close on those two dimensions simultaneously.

The infrastructure ranking — 32nd globally — is not a minor footnote.[GII 2025] It reflects real constraints: power grid capacity is the binding constraint on AI data centre expansion, broadband availability remains uneven in rural and lower-income urban areas, and the gap between innovation output and physical deployment infrastructure is widening. The CHIPS Act and the Infrastructure Investment and Jobs Act were designed to close this gap — federal investment in domestic semiconductor manufacturing and broadband expansion. Specific deployment figures for both programmes were not available in current published sources; the Commerce Department and NTIA are the authoritative trackers of these programmes.

U.S. and Chinese multinationals together lead the global digital firms ranking,[World Bank] meaning the U.S. private sector is generating digital economic value at scale. The structural risk is that this leadership is concentrated in a small number of very large companies — and those companies are increasingly subject to the political dynamics described in the governance section. For businesses entering the U.S. market, digital infrastructure is strong in major metro corridors and weak at the edges. Planning around that geography matters.

The United States is simultaneously the world's largest consumer market and — in 2026 — the world's most active generator of trade disruption. The April 2025 tariff announcements imposed broad import duties across key categories, with Coface estimating that 80% of the costs are borne by U.S. businesses and consumers rather than exporters.[Coface] The short-term political rationale is domestic — protecting manufacturing employment and generating revenue — but the operational consequence for multinational businesses is higher input costs, longer supply chain planning cycles, and reduced predictability.

The Supreme Court is expected to rule in 2026 on the scope of executive authority to impose tariffs without Congressional approval.[Coface] If the Court limits executive tariff power, existing tariff structures could be unwound relatively quickly — a scenario that would benefit import-dependent businesses but disadvantage domestic manufacturers who invested in response to tariff protection. If the Court upholds executive authority, the current tariff architecture is likely to persist through the election cycle and potentially beyond.

For inbound market entry, the U.S. market's scale remains unmatched. An e-commerce market projected at $6.9–$8.1 trillion globally by 2026 has the U.S. as its largest single-country component.[Research] The combination of a 335-million-person consumer base, high per-capita income, deep digital payment infrastructure, and sophisticated logistics networks makes the U.S. irreplaceable for any business with global ambitions. The trade risk is real — but it is a cost variable, not a market-access variable.

The base case for the United States is straightforward: the world's largest economy, with strong innovation capacity, a mature legal system (despite current political pressure), deep capital markets, and a consumer base that no serious global business can ignore. The CBO projects potential GDP growth of 2.1% annually through 2030,[CBO] unemployment declining from 4.3% toward lower levels, and inflation returning to near the 2% target. The sectors attracting the most capital — AI, clean energy, biotechnology — have multi-decade tailwinds that do not depend on which party controls Congress.

What has changed in 2026 is the width of the scenario distribution. Governance risks that were previously theoretical — executive intervention in corporate decisions, tariff policy as a political tool, challenges to central bank independence — are now documented realities.[Harvard][Eurasia Group] This does not change the central estimate. It widens the range of outcomes on either side. A November 2026 election that changes House control could accelerate a return to institutional norms, compressing downside risk. A scenario where institutional checks continue to erode could push the U.S. toward a governance environment that increases the cost of doing business in ways that no forecast currently prices.

For businesses evaluating U.S. entry or expansion in 2026, the relevant question is not 'is the U.S. viable?' — it clearly is. The question is 'what is the cost of the uncertainty premium, and can our business model absorb it?' Companies with diverse global operations, pricing power, and limited supply chain exposure to tariff categories are well positioned. Companies with concentrated U.S. regulatory exposure, single-source supply chains through tariffed geographies, or business models that depend on policy stability are carrying more risk than their spreadsheets may show.
