Combination?", page 8

3.       Please clarify if the sponsor and its affiliates can earn a positive
rate of return on their
         investment, even if other SPAC shareholders experience a negative rate
of return in the
         post-business combination company.
4.       Please quantify the aggregate dollar amount and describe the nature of
what the sponsor
         and its affiliates have at risk that depends on completion of a
business combination.
         Include the current value of securities held, loans extended, fees

         expenses for which the sponsor and its affiliates are awaiting

Summary, page 17

6.       In an appropriate location in this section, please revise your
disclosure to show the
         potential impact of redemptions on the per share value of the shares
owned by non-
         redeeming shareholders by including a sensitivity analysis showing a
range of redemption
         scenarios, including minimum, maximum and interim redemption levels.
7.       Please revise to disclose all possible sources and extent of dilution
that shareholders who
         elect not to redeem their shares may experience in connection with the
business
         combination. Provide disclosure of the impact of each significant
source of dilution,
         including the amount of equity held by founders, convertible
securities, including warrants
         retained by redeeming shareholders, at each of the redemption levels
detailed in your
         sensitivity analysis, including any needed assumptions.
8.       It appears that underwriting fees remain constant and are not adjusted
based on
         redemptions. Revise your disclosure to disclose the effective
underwriting fee on a
         percentage basis for shares at each redemption level presented in your
sensitivity analysis
         related to dilution.

         of the merger in the filing and whether you intend for the merger to
qualify as a
         reorganization within the meaning of Section 368(a) of the Internal
Revenue Code. To the
         extent you believe that the merger qualifies as a reorganization
within Section 368(a) of

11.    We have reviewed your response to prior comment 12. Please address the
following
       items;
           Your response indicates that on March 7, 2021, you signed the
definitive merger
           agreement with dMY with a pre-money equity value of $1.275 billion
and the fair
           value of IonQ's common stock was determined to be $31.71 per share.
Further, your
           response states that on March 8, 2021, you announced the proposed
business
           combination with a pre-money equity value for IonQ of $1.275
billion, which
           resulted in an implied fair value of the shares of IonQ common stock
to be $41.30 per
           share. Please explain what occurred to result in the change in the
fair value of the
           shares during this one day.
           Given the final implied fair value of $41.30 on March 8, 2021,
please explain in
           greater detail how you concluded your deemed fair value of shares on
recent grant
           dates, for example, $30.61 on March 4, 2021 remains appropriate. We
note your
           disclosure under the title, Reassessment of 2021 Awards, that "IonQ
did not identify
           any significant events that occurred during the period between
valuation dates that
           would have caused a material change in fair value."
