Thesis
Hesitation is not cost-neutrality. It is a bet that entry in two years will be cheaper than entry today. This bet is quantitatively losable, because authority in LLM retrieval compounds, it does not grow linearly. Whoever starts in 2028 does not pay for 2028 conditions, but for the accumulated lead of competitors over three intervening years.
The one number
A 12-month mandate with Q4 2026 start reaches around 32 per cent in additional cost compared to a Q4 2025 start.
Not because of inflation. Because of authority compounding. Established domains accumulate mentions, citations and retrieval signals that newly entering operators must catch up with at higher volume and over a longer runtime. The schedule: around 1.15× over six months, around 1.32× over twelve months, around 1.75× over 24 months as a strategic outlook. The calculation sits below.

The cited top-30 domains fluctuate monthly, but the authority accumulation of established publishers raises the threshold for late entrants. Between 2026 and 2028, competitors accumulate three years of mention signals (Ahrefs correlation 0.664).

Monthly production must rise, because work runs against three years of accumulated competitive signals. +50 to +100 per cent publication volume for the same mention-share target. Cost per article remains compliant with the NB Procurement Standard, but the runtime total rises.

without it: invisible
Similarweb declared referral volume plateauing (Q1 2026). That means: growth is slowing, positions are hardening. Whoever is not cited in 2028 is not reticent, but invisible, and invisibility at tier-1 operators directly costs market share.

Portal commission
double-digit % / contract
If the upstream influence layer is not built, the operator compensates the gap via comparison-portal commissions. In the DE telco sector these typically sit in the double-digit per-cent range per concluded contract. The margin migrates structurally, not temporarily.

The rational conclusion
Entry is possible at any time. It is cheapest today.
This is not urgency rhetoric. It is the mathematics of accumulating authority signals. With every passing quarter, the price for the same result rises, not linearly, but compoundingly.
