The SI Wave: What Domain Investors Need to Know

Every technology wave creates a domain wave. Social media created demand for names with "social," "share," and "connect." Crypto created demand for "chain," "coin," and "meta." AI created demand for anything ending in .ai.

The SI wave is next. Here's what domain investors need to know.

Si Wave: The demand driver

Research investment in superintelligence and synthetic intelligence is accelerating — billions of dollars from the largest tech companies and a growing number of dedicated SI/ASI startups. Each one needs names, domains, and positioning. The demand curve is the same one that made .ai a 600% growth story.

The supply picture

On .com, SI-related keyword names are mostly claimed. On .ai, there's moderate inventory at aftermarket prices. On .si, there's significant inventory at registration prices. The arbitrage is clearest on .si: names that would cost $10,000–$50,000 as .ai are available for $50–$200 as .si.

Timeline expectations

The .ai wave took roughly 4 years to go from niche to mainstream (2019–2023). If the SI wave follows a similar trajectory, the repricing window is 2026–2030. Patient capital is rewarded; quick-flip expectations are unrealistic.

Realistic risk assessment

The SI category might not materialise as an independent wave. It could be absorbed back into "AI." The .si ccTLD could face policy changes. The aftermarket for .si names is currently thin. Size positions for speculative upside, not core portfolio value.

When evaluating si wave, start with the fundamentals: what problem it solves, who it serves, and how it compares to the alternatives buyers consider first.

Start with the fundamentals. Define who you are serving, the single outcome you want, and the budget you are comfortable committing before you compare any options.

A practical rule is to favour clarity over cleverness. The choice that is easiest to understand, spell, remember and act on tends to win over the long run.

Context changes the answer. What is optimal for a fast-moving startup is rarely optimal for an established brand, so weigh your own stage, market and ambitions.

Avoid the common mistakes: rushing the decision, copying competitors blindly, and ignoring the total cost of ownership beyond the very first year of use.

Think in terms of trade-offs rather than a single perfect answer. Every option trades memorability, cost, reach and flexibility in a slightly different mix.

Document your reasoning. Writing down why you chose one path makes it far easier to revisit the decision later and to explain it to partners and investors.

Test with real people. A quick check with a handful of your actual customers will surface problems that no amount of internal debate ever reveals.

Plan for growth. The option that fits today should still make sense when your audience, catalogue or team is several times larger than it is right now.

Finally, revisit the decision periodically. Markets, tools and best practices move quickly, and a choice that was ideal last year may deserve a fresh look today.

Frequently asked questions

Is the SI domain opportunity as big as AI was?

It could be, if the SI category matures independently. It's smaller and more uncertain — but the entry prices are vastly lower, so the risk/reward per name is comparable.

How long should I hold .si domains?

Plan for a 3–5 year hold. The repricing will be gradual — patient capital wins.

What .si names should I focus on?

Short (2–5 chars), one-word English dictionary words, AI/tech keywords, and brandable coined names. The same quality filters as .com and .ai.
