No. Having US$1,015,000 available does not create a visa number. The gift is made when USCIS instructs you to make it, and availability depends on your classification and chargeability area. A couple applying together commits US$2,030,000 in programme amounts, and that figure buys eligibility evidence, not priority.
Liquidity is your constraint; visa numbers are not
Consider a Mont-Royal couple who sell a holding to have funds ready in advance. Their readiness affects only their own risk: the US$15,000 per person is explicitly non-refundable, while the qualifying gift is instructed later in the sequence. Nothing about early liquidity accelerates a category with limited numbers, so treat the funding date and the visa date as two separate lines in your plan.
The Gold Card gift is money given to the U.S. government with no return and no project; EB-5 capital is invested at risk in an enterprise that must create jobs and may or may not repay. The gift is not recoverable business equity or EB-5 capital, and the programme relies on EB-1 or EB-2 classification rather than purchasing a conventional visa outcome.
