Germany’s Alternative for Germany (AfD) is this week the country’s most popular party in two named national polls. Yet it does not govern. That gap — between a survey lead and the power to write law — is what should govern how investors read the next two Sundays.

Infratest dimap, the Berlin firm that runs the monthly Deutschlandtrend for ARD, Germany’s main public broadcaster, and Forsa, a commercial pollster for the private channels RTL and n-tv, both put the AfD first this week, at 27% and 28%. The governing center-right alliance — the Christian Democratic Union (CDU) and its Bavarian sister party, the Christian Social Union (CSU), together called the Union — is at 21% in each survey.¹, ² In the 23 February 2025 election to the Bundestag, the AfD took 20.8% of the party-list vote and 152 of 630 seats — second, behind the Union at 28.6% and 208 seats.³ Sachsen-Anhalt votes for its Landtag (state parliament) on 6 September; Mecklenburg-Vorpommern and the city-state of Berlin follow on 20 September.

The crucial variable is the Brandmauer, the refusal of other parties to form a coalition with the AfD. It is why Chancellor Friedrich Merz’s Christian Democrats govern with the center-left Social Democrats (SPD), not with the party that now outpolls them. Until that firewall cracks, the AfD functions as a shadow agenda-setter: able to force shifts on migration and industrial power, unable to sign them into law. Over the next six to eighteen months those shifts will outrun any move into the federal cabinet. Dexit, a Russia reset, and an AfD government stay blocked while other parties refuse coalition, ministerial office, or formal toleration.

Sunday’s count will show how popular the party is. The talks after will show whether anyone will let it govern.

From Second Place to Policy Catalyst

The February 2025 election ended the Ampel, the traffic-light coalition of Social Democrats, Greens, and Free Democrats. Merz formed a Union–SPD cabinet, leaving the AfD as the largest opposition party, 10.4 percentage points above its 2021 share.³ On 5 September the aggregator dawum showed a population-weighted average of state-parliament polls at 19.7% for the AfD in the former West and 34.8% in the former East, including Berlin.¹⁰ Eastern strength scrambles coalition arithmetic in the states long before it produces a federal majority.

March in the West showed the other side of the map. In Baden-Württemberg on 8 March 2026 the AfD won 18.8%, finished third, and took 35 of 157 seats.⁴ In Rhineland-Palatinate on 22 March it won 19.5% and finished third again.⁵ The party can be exceptionally strong in the East and still appoint nobody to a federal ministry.

Three grievances drive the rise: asylum inflows felt in housing and schools; the post-2022 power-price spike and a law that pushed households to replace gas and oil boilers; and distrust of the parties that have rotated through office since reunification in 1990. The AfD’s offer is halt irregular entry, cheap conventional power, and an attack on the firewall itself. The Union has tried to compete on the first two without touching the third.

First asylum applications at the Federal Office for Migration and Refugees fell from 229,751 in 2024 to 113,236 in 2025, a drop of 50.7%.¹¹ Routes, other EU decisions, and the cycle of earlier inflows sit in the same year; the coalition still has every political reason to show control, and none to adopt Remigration, the AfD’s word for large-scale deportation of non-citizens, sometimes framed more broadly. The overlap is the wish for lower energy costs and tighter inflows. The divergence is the generation mix, Russia, and whether policy stays inside EU law. The Union will adopt stricter borders and talk industrial power caps. It will not cross the Brandmauer for the AfD’s agenda on EU membership or Russia. What firms already face is AfD-lite.

Rhetoric Versus Delivery

The platform is expansive. Asylum claims would be lodged outside the EU; returns would accelerate; Remigration would become policy. Nuclear would reopen, coal would run longer, Paris targets would go, long-term Russian gas would return. On Europe the party prefers a loose “bund of nations,” keeps a German EU exit (Dexit, on the Brexit model) as a fallback, and would end Ukraine arms and lift Russia sanctions. On tax it would abolish the solidarity surcharge — the extra levy on income tax first charged to help rebuild the East after 1990 — and inheritance tax, while still keeping the Schuldenbremse, the constitutional debt brake.

The feasibility of this agenda is near zero without executive power. Remigration collides with the Basic Law and EU asylum rules. A generation-mix reversal hits closed plants, EU climate law, and years of build time. Dexit would put at risk the single market German exporters live on. Article 115 caps the federal structural deficit at 0.35% of GDP.¹² The solidarity surcharge yielded about €12.6bn in cash in 2024; assessed inheritance tax in 2025 was €13.3bn.¹³, ¹⁴ Cutting both while keeping the brake means spending offsets or a constitutional amendment, neither of which an opposition party can pass.

Migration enforcement and industrial-price politics already move through the Union–SPD cabinet. BDEW, the German utilities association, put new-contract industrial electricity for small and mid-size firms at 17.2 cents per kilowatt-hour for 2026, against 17.64 cents in 2025. The renewable-energy surcharge (EEG) on that bill has been zero since 2023.¹⁵ There is no unused levy left to repeal. Manufacturing was 19.7% of German gross value added in 2024 — the slice most sensitive to those bills.¹⁶ Tax abolition, Dexit, and a wholesale Russia reset wait on a finance ministry the party does not hold.

The legal cloud is narrower than a ban and broader than a nuisance. On 2 May 2025 the Federal Office for the Protection of the Constitution raised the federal party to a “confirmed right-wing extremist endeavour.” On 26 February 2026 the administrative court in Cologne barred the service, pending the main case, from classifying or publicly treating the federal party as that confirmed endeavour.¹⁷ As of 17 June 2026, Correctiv reported five state branches that state intelligence offices may still call confirmed extremist: Brandenburg, Lower Saxony, Saxony, Sachsen-Anhalt, and Thuringia.¹⁸ Only the Bundestag, the Bundesrat, or the federal government may petition the Federal Constitutional Court in Karlsruhe; no such petition is treated here as filed. For firms the immediate consequence is counterparties and reputation, especially in the East.

What Firms Are Pricing

The probable path — by some distance, perhaps seven chances in ten — is that the Brandmauer holds. The AfD remains locked out of the federal cabinet and still forces the coalition toward border enforcement and factory energy subsidies. For bulk power users that near-term climate is mixed-to-favourable: factory-price relief without a change of government.

A state-level breach, nearer one in four than a shock, would raise regional friction and noise in Brussels. A minister-president, a ministry, or a tolerated minority would not itself write a Dexit, restart Nord Stream — the Baltic pipelines that once brought Russian gas to Germany — or abolish the solidarity surcharge. It would show the firewall is a declining convention.

The tail, perhaps one in twenty, is a material route toward federal executive participation: generation-mix reversal, a fight over Ukraine aid, deep friction with the EU and the United States. Exporters would carry that exposure, not the domestic power bill. The shares in the diagram are a judgement. A national poll that prints 26 instead of 28 leaves them where they are.

After Magdeburg

Two polls put the AfD at 42–43% in Sachsen-Anhalt ahead of 6 September: Infratest dimap at 42% and INSA at 43%.⁶, ⁷ The question that matters is what happens after such a result. A first-place finish followed by a united refusal to govern with the AfD would leave the firewall as law and raise the pressure on the Union to compete on migration and energy. An AfD executive role would do the reverse: Dexit would remain distant, but the assumption that has kept the high-delivery path remote would be broken.

The 20 September elections are the second test. In Mecklenburg-Vorpommern the last named Infratest poll has the AfD at 35% and the SPD at 32%.⁸ In Berlin, Infratest has the AfD at 18%, behind the CDU at 21% and The Left at 19%.⁹ A strong eastern-rural result beside a weaker metropolitan showing would be geographic polarisation and harder state arithmetic — the March western thirds already point that way. Only Sunday’s count in Magdeburg, and the 20 September counts in Schwerin and Berlin, are results.

Over the next year the federal Brandmauer should hold. Apocalyptic scenarios — Dexit, a sudden restart of Nord Stream, the abolition of key levies — remain structurally blocked. The Union–SPD coalition will keep executing AfD-lite on borders and factory bills. A two-point miss in tomorrow’s poll leaves that reading intact; a durable breach of the firewall rewrites it.

Watch the coalitions. If the AfD finishes first and still faces a united opposition bloc, the firewall holds as law; if any local branch of an established party forms a working majority with it, the tail moves closer.

Watch the courts. Cologne’s merits ruling can change compliance judgements without deciding who governs.

The definitive takeaway for this month's balance sheet is not how high the AfD climbs in the polls, but whether any established party is finally willing to share power with them.
