The largest deal in this ranking is AirCar’s reported $5 million offer for 50% of the company. The next two entries each reached $3 million. These are amounts and terms reported for deals announced on air—not confirmation that every deal closed or that the investors earned a return.
How this ranking works
The entries are ordered by the investment amounts reported for their televised deals, using Shark Tank Index’s 2025 ranking. That database is a secondary source, not an official show record. The terms below should be read as on-air offers or commitments; the available sources do not confirm that all eight survived due diligence or resulted in the stated investment.
Three deals tie at $2 million, so they share ranks six through eight. Equity percentages describe the reported terms and do not, by themselves, show company value, later performance or investor return.

What stands out about the terms
AirCar is the largest reported amount
At $5 million, AirCar leads the ranking by amount. Herjavec’s reported offer was for half the company, so the largest check did not buy the whole business.
Moki Doorstep stands apart on ownership
Moki Doorstep’s reported $3 million for 100% is described as a full-company acquisition, rather than a conventional minority investment. That makes its terms structurally different from the other entries and cautions against comparing the percentages as if each deal used identical mechanics.

The tied $2 million deals offered different shares
Ten Thirty One Productions, Vengo and Fizzics each have a reported $2 million amount, but the stated equity ranges from 10% to 20%. The amount alone therefore does not show how much ownership a founder gave up.
D Best Products’ valuation figure is inconsistent
The ranking source also gives D Best Products a $1.8 million valuation, but that figure conflicts with its reported $2.35 million investment for 20%. If those terms represent a conventional equity investment, the arithmetic implies an $11.75 million post-money valuation. Because the source does not resolve the inconsistency, the ranking above leaves out its stated valuation.

Deal size is not a measure of success
A televised amount answers how large a deal was reported to be, not whether it ultimately closed, how the company performed, or what an investor made. The available sources do not establish profitability, final deal completion or investor returns for all eight companies. Inc. describes Ten Thirty One Productions as a creator and producer of live Halloween attractions and reports a Ticketmaster partnership and a separate Live Nation investment; those facts provide context, but do not establish the outcome of Cuban’s Shark Tank deal.
