I'm married and file separately. We have a tenant in common / joint brokerage account. The account is 100% funded by me. Can I claim 100% income/loss from this account?

I just got married this year and the brokerage account became tenant in common account after the marriage. The bank does not send separate 1099. Since it is fully funded by me, can I claim all the income/loss in my filing and my spouse does not claim anything from the account in their filing?
