The Infinite Exchange
$18.9Oc base cost · $1.67Qi/sec
Business Overview
The final tier. Beyond counting.
Every tycoon's portfolio eventually includes a The Infinite Exchange — reliable, scalable, and easy to reason about.
Cost Scaling
Every business in Tycoon Cards uses the same cost curve: each copy costs 15% more than the last. For the The Infinite Exchange, that looks like this:
| Copies owned | Cost of next copy | Total spent to reach this many |
|---|---|---|
| 1 | $21.7Oc | $18.9Oc |
| 10 | $76.4Oc | $383Oc |
| 25 | $621Oc | $4.02No |
| 50 | $20.5No | $136No |
| 100 | $22.2Dc | $148Dc |
Income Scaling
Income scales linearly with copies owned — no diminishing returns, ever. Owning more of the The Infinite Exchange always earns proportionally more:
| Copies owned | Income per second |
|---|---|
| 1 | $1.67Qi/s |
| 10 | $16.7Qi/s |
| 25 | $41.7Qi/s |
| 50 | $83.5Qi/s |
| 100 | $167Qi/s |
Profit Calculations
| Payback period (1st copy) | 11,307,305,733 seconds |
| Income per dollar spent | $0.0/s per $1 |
See the Business Tier List for how this business ranks against all other 99 tiers by payback period.
Unlock Requirements
There is no gating system on businesses in Tycoon Cards — the The Infinite Exchange is available to purchase from the very start of any run, the moment you can afford its $18.9Oc base cost. The only realistic "requirement" is reaching that amount of money, either by clicking, by owning cheaper businesses, or by carrying prestige and card bonuses from a previous run.
Best Upgrades
Individual businesses don't have their own upgrade trees in Tycoon Cards — the The Infinite Exchange always earns exactly $1.67Qi per copy at base rate. What actually "upgrades" its value are the game's shared systems: levelling supporting cards (below), earning achievement bonuses, and increasing your prestige multiplier. Each of these applies as a percentage on top of every business you own, including this one.
Best Supporting Cards
At this tier, all-income and passive-income cards deliver the biggest absolute gains, since a percentage bonus on a high-earning business is worth far more in raw dollars than the same percentage on a cheap early tier.
Prestige Recommendations
Reaching this tier is typically a late-run or veteran-account milestone. If you're here, you're likely earning enough lifetime income to justify a prestige reset for a meaningful batch of prestige points.
Read the full Prestige Guide for general reset timing, or the Prestige Point Planning guide to calculate exactly how many points your next reset will earn.
Research Interactions
Tycoon Cards does not currently include a research-tree system — the The Infinite Exchange cannot be researched or unlocked through any mechanic beyond simply affording it. A research tree is listed as a possible future system on our Updates & Roadmap page; this section will be updated if that ever changes.
Evolution Path (Tier Progression)
Businesses in Tycoon Cards don't evolve or transform — each tier is a permanent, independent business. What we can show honestly is this business's place in the overall 100-tier progression:
- Previous tier: ✨ Cosmic Singularity Corp ($12.2Oc base cost)
- This tier: ♾️ The Infinite Exchange ($18.9Oc base cost)
Visual Progression
The five tiers surrounding the The Infinite Exchange in the business roster:
Best Strategies
- Reserved for veteran accounts with substantial prestige multipliers — the cost only makes sense once your income bonuses are well developed.
- Treat owning this tier as a long-term goal for a run rather than something to rush toward immediately after a prestige reset.
- Remember that all businesses share the same 15%-per-copy cost curve, so the fundamental buy/hold maths never changes — only the absolute numbers do.
