The salient point about HHS's enrollment projection for the ACA marketplace in 2017 is that it does not project any growth in the individual market as a whole.
The ASPE brief laying out the forecast projects 13.8 million enrollments in the ACA marketplace by the end of open enrollment 2017, an increase of 1.1 million over the end of the 2016 enrollment period. That estimate includes 1.1 million people expected to move from off-marketplace coverage into the marketplace -- a projection based on HHS's recent estimate that 2.5 million off-marketplace enrollees are potentially eligible for marketplace subsidies.
Since insurers' ACA-compliant off-marketplace plans share a risk pool with their on-marketplace plans, a total market that stays flat will not improve insurers' risk pools, except to the extent that those who come on-marketplace switch from pre-ACA grandfathered and grandmothered plans (as far as I can tell, the ASPE brief does not clarify whether some of the anticipated transfers will come from such plans, which are phasing out). Thus the individual market as a whole may not be any more attractive to insurers next year than this year, except to the extent that this year's price hikes cover last year's losses, or the pent-up demand for medical care on the part of previously uninsured marketplace enrollees starts to level off, or regulatory and risk adjustment changes have a positive effect.
On the other hand, as Kaiser's Cynthia Cox pointed out on Twitter, a transfer from off-marketplace to on-marketplace may reduce insurers' temptation to end their marketplace participation and sell off-marketplace only in some regions.
